Important Installation Points
The unit must be installed to comply with national regulations and/or codes of practice. A qualified
electrician must carry this out.
Ensure at least 39” (1000 mm) clear front access to the electrical and steam sections.
Do not locate the cabinet where the ambient temperature around the unit could exceed 95ºF (35ºC);
or fall below 40ºF (5ºC) e.g., an unventilated roof mounted enclosure – see minimum space /
ventilation requirements pages 4 - 7.
Do not locate the cabinet where a ladder is required for service access as this could make
servicing and cylinder service or exchange hazardous.
Make sure steam line(s) have adequate slope (min 12%) for condensate drainage and use
condensate separators if the pipe is lower than the unit.
Provide adequate support to prevent sags developing in flexible steam lines, which can fill with
water and create a "trap".
Do not locate vented drain directly under the cabinet.
Important Electrical Connection Items
Vapac only recommend the use of UL recognized stranded copper conductors, adequately sized
for the unit - The use of aluminum conductors is not recommended.
Before commissioning the unit, check that all electrical (power) connections - including those at
the terminals and contactor are tight.
Check that the transformer primary winding connection is correct for the supply voltage at Vapac
terminals A1 & A2.
The Vapac transformer must not be used to power other equipment.
To comply with EMC aspects see recommendations on page 10.
Do not mount the 'LE' unit close to a source of strong electromagnetic emissions, such as a
variable speed motor drive, Kva transformer, or 'UPS' unit.
A minimum gap of 2 meters must be maintained between the unit and such devices.
Larger output devices may require an increased gap distance, depending on the nature of
screening / filtration measures fitted to the device.
Use a high-limit humidistat connected to ensure positive interruption of unit operation when overhumidification is detected (page 19).
It is important that the control signal connected to terminals 5 & 6 must be referenced to ground at
the control PCB – this can be done by linking either terminal 5 or 6 to terminal 7.
NB if the controller output is referenced to ground, it is important that the “leg” which is
connected to ground at the controller is also connected to ground at the Vapac unit. Grounding
the opposite “leg” will cause damage to the controller and/or the Vapac control PCB.
Important Maintenance Items
Only a qualified electrician should carry out maintenance.
The boiler contains hot water, and must be drained before any maintenance is carried out on the
steam section. This should be done prior to isolating the power, and removing the front access
panel
ESD SENSITIVE DEVICES USED ON PCB. ENSURE ANTI-STATIC PRECAUTIONS ARE TAKEN
WHEN REMOVING OR REPLACING PCB’S.

Flexible Steam
Pipe.
Steam pipes should be positioned as shown below,
allowing a minimum rate of fall back to the unit of
12% to allow the free flow of condensate back to the
unit. If the above fall is not possible, then
condensate separators must be fitted as shown in
figure 1.
The position of the steam pipe or multipipe in a airconditioning system relative to other items such as
bends, filters, heat exchangers, etc. is critical. The
steam pipe must not be located closer to such item,
than the entrainment distance, and must be decided
by the design engineer responsible for the project.

Plumbing Considerations.
Do’s
1.3.1
Cold water supply.
Do install a stop-valve/Shut-off valve and a strainer close
to the unit.
Do provide a water supply with sufficient pressure and
pipe size to ensure an adequate flow rate to all units
connected to the system.
Do use the water connection with nylon nut provided.
General
The Vapanet range of electrode boilers is capable of
operating with a range of “raw mains” water quality. The
water supply should be within the following limits:Hardness
50 – 500 ppm
Conductivity
80 – 1000µS
PH
7.3 – 8.0
Silica
0
Pressure of between 1 – 8 bar (22 – 116 psi.)
Don'ts
Don’t use a wrench or other tool to tighten the water
supply connection - the nylon nut and rubber washer
provided, should only require tightening by hand to
effect a seal. If water seepage occurs, undo the nut to
wipe the washer clean and re-seat it.
In addition, if stainless steel electrodes are used the
chloride level must not exceed 170 ppm.

Electrical Connections
Important Power Connection Information
Vapac 24V and 9 V secondary Transformer Primary supply connections:
Vapac units are wired to allow connection to alternative site Voltages.
Make the following simple checks before connecting the power supply:Move the RED connection on the VAPANET transformer primary winding circuit to the
position marked with the supply Voltage that is to be connected between VAPANET
power terminals A1 and A2.
The transformer primary circuit terminal positions are clearly marked: - 120V, 208V,
240V, 460, & 600V. The transformer is fitted below the Drain tray, and is accessible by
removing two screws and the cover, which should be slid it towards you.
Note:

Control Cable / Security Circuit
Screening Arrangement
Important E.M.C. Considerations
Use a dedicated, earthed metal conduit for both the
control signal cable and the security circuit cables along
their entire length - they may share the same conduit
where practicable. The earth must be made by "metal-tometal" contact and should be a good RF (Radio
Frequency) earth.
Tail to be kept short
(less than 50mm)
The control and security circuit connections should be run
in screened cable with the screen grounded at the
VAPANET end (onto the electrical section back panel).
The screen should be maintained as close as possible to
the cable ends and any tail between the screen and the
earth point must be kept short (50 mm maximum).

1.4.2
Power Supply Connection
The unit requires the following connections as shown in the
diagram below
1.4.2.1 Volt free alarm outputs
The unit has connections for volt free alarm outputs these are on
the three double terminals next to the main power input terminals.
The top terminals are for unit volt free fault alarm as follows:
542
543
544
common for fault alarm
Normally closed when no fault
Normally open when no fault
The bottom terminals are for unit volt free run signal as follows:
545
546
547
Common for run signal
Normally closed when unit is in standby or
fault (not running)
Normally open when unit is in standby or fault
(not running)
If the unit is part of a master slave system or network, the
run & fault outputs can be selected (via keypad & display)
as either network (system) or unit only. This is selectable
at Service Engineers Level, in the Engineering Menu, in
the window “Fault/Run Scope”. The default is “network”. It
is possible to get both alarm & Run indication in all units:
Single cylinder units will give this indication if the service
interval has expired; Twin Cylinder & Networked units will
give this indication if the service interval has expired or if
the master cylinder is operating and any slave cylinder (or
cylinders) are in fault.
1.4.2.2 Unit control terminals
For unit control and network termination see section
1.5 the terminal layout is shown.

1.4.3
Electrical Connections
1.4.4
The wiring to the Vapac should be done by a qualified
electrician. The external over current protection and wiring
should comply with the appropriate Regulations and
Codes of Practice.
Cable Entry Provision
Cable glands must be used to ensure cables are held
securely at the entry position. All Vapac cabinets are
equipped with a removable gland-plate. The installing
electrician should remove this and take it to a work-bench
to drill for the required cable gland size.
Important: Make sure the connection to the primary
Voltage winding of the Vapac transformer matches the
supply Voltage which is to be connected between Vapac
terminals A1 & A2.
1.4.5
Vapac Control Circuit Transformer
The internal control circuit of the Vapac unit operates at
24Vac - the transformer secondary is set at 24V.
A fused disconnect / isolator or MCB should be used to
disconnect the supply from all electrodes simultaneously.
As standard the Vapac VAPANET includes a transformer
with alternative primary winding options 208V, 230, 460,
and 600V and requires on site adjustment to match it to
the Voltage connected to Vapac terminals A1 and A2.
The transformer also has a 9V secondary tapping which
provides power to the VAPANET 1150630 PCB.
This must be sized to suit the total maximum phase/line
current of the unit and should be located adjacent to the
Vapac cabinet or within easy reach and readily accessible.
In Vapac VAPANET units terminals A1, A2 and A3 are for
the power supply connections as indicated in the diagrams
below (twin cylinder units have two supplies A1, A2, A3 &
B1, B2, B3).
Important: The Vapac transformer must NOT be used to
power other equipment or the warranty will be invalidated.
1.4.6
RDU Connection
Vapac terminals 25 & 26 are included to provide a 230Vac
electrical supply for the fan motor in the RDU (Room
Distribution Unit) .
Note: The 230Vac at terminals is derived from the
incoming electrical supply to the Vapac. If the local supply
cannot provide 230Vac (example 400V No Neutral supply)
it will be necessary for a transformer to be fitted in the
RDU as indicated below.
Twin cylinder units’ have terminals for the connection of
two power supply input circuits. On twin cylinder units’ this
allows individual external protection of each steam
cylinder. Fused disconnect/isolator or MCB provision must
be linked to ensure both 3 phase supply inputs are
disconnected simultaneously.
Notes:1.
2.
3.
All units must have a PE earth connection connected to the units terminal.
Unit with N.A. in the following tables means NOT AVAILABLE there is not a unit available to run at the voltage
and phases shown. Please check that the correct model reference is ordered and installed, for the low or high
voltage required, and at the desired steam output.
Standard design is for 60 Hz Supplies.
FOR FULL ELECTRO-MAGNETIC COMPATIBILITY A NEUTRAL CONNECTION IS REQUIRED FOR ALL PROPORTIONAL
UNITS AS INDICATED IN THE CONNECTION DIAGRAMS ON THE FOLLOWING PAGES.
RDU Connection
The three type’s of RDU are for various voltages and phase without neutrals connections that can be made to the Vapanet unit. Please refer to
the Microvap connection diagram on the following three pages as to which type of unit is required. On twin cylinder units two fan circuits as
shown below one for each cylinder will be in the RDU unit.

Master/Slave System
For larger duties, VAPANET “Electrode boiler” units can be interconnected and arranged to operate from one proportional signal as a
Master/Slave system. The system allows up to 10 cylinders to be linked in this way. The slave units will all be “on / off” units. The master
unit, to which the proportional signal is connected, can be “on / off” but will preferably be a “proportional” unit.
To “configure” a system, ensure that the control signal is zero [disconnect the control signal, or switch the units off at the front panel switch].
Press and hold the service pin on the master control PCB, until the user LED’s flash amber, release and check that the LEDs flash
red/amber/green, if not repeat the procedure. Then press the service pin (network button) on each of the slave control PCB’s in the order
that they are required to operate, the slave user LED1 will flash Green/amber until it is configured, once the light goes out [or flashes
red/off], proceed to the next slave. If units of different capacity are used, ensure that the master is equal to or greater than the capacity of
the slaves, and that the largest capacity slaves come on before the smaller capacity units]. Once this process is complete, confirm the fact
by pressing the service pin on the master PCB until user LED2 goes green [this step is not necessary if all nine slave cylinders are
configured].
NB. The total cable length of the network (using the cable recommended by V.H.C.L. – Our part
number 8040251) is 500 m and it should be assumed that there is 1 m of cable in each unit of the
“system” (including the “master”).

Start-Up / Operation
2.0.1
Start-up check list
a)
Water supply and Drain Connections:
these should be connected as indicated
under Plumbing and in accordance with the
relevant local regulations. An isolation valve
should be adjacent to the unit. The
connecting metal plumbing must be
grounded close to the unit.
Steam Line: This must be connected
according to the installation instructions with
adequate slope and support.
Power supply: Wiring to the Vapanet unit
Should be by a qualified electrician and
comply with the relevant regulations using
appropriately sized cable and cable glands,
with disconnect and fuses to suit the
maximum fuse rating of the unit at the supply
Voltage. The disconnect/fuses should be
adjacent to the unit or within easy reach and
readily accessible.
Control Connections: Ensure the control
signal and security circuit are
correctly connected according to the relevant
instructions/diagrams.
VAPANET 24v / 9V Control Circuit
Transformer:
The
standard
24V
transformer used in the units has primary
winding for 120V, 208V, 230V, 460V, & 600V
60Hz connection derived from the local
electrical supply.
The maximum output & kW rating of the unit
is determined by a Current Set Plug. It is
therefore possible to down rate units to any
output, down to approximately 50% of the full
rated output.
Unit Configuration Plug (U.C.P.). Sets the
maximum current level for the unit. It is fitted
directly onto the control P.C.B. If a display is
fitted, it is the only resistor required to be
fitted to the control P.C.B.. However if no
display is present additional resistors need to
be fitted, to provide the microprocessor with
information relating to the control signal etc.
For ease these are fitted to a small PCB
fitted to CR4 of the PCB, and resistor
selection is via shorting links, see control
signal selection on page 13. If insufficient
information is available the unit will remain in
the “not_config” state (see “Used LED” on
page 19) until the information is supplied.
This additional information is provided via
the keypad – when the display is fitted.
b)
c)
d)
e)
f)
g)
2.0.2
The display (if fitted) will now show the Set-Up
procedure.
Follow the procedure by:
selecting: the preferred language,
Attaching the control PCB to the Display.
nominating: the type/quality of the supply
water.
nominating: the control signal (or Vapac sensor
when being used).
When the control signal has been nominated, the SetUp will be entered into the memory. The Set-Up can
then be checked by reading the information menu. If
an error has been made, it will be necessary to go
back to the Set-up menu. If no display is fitted the
information is set using the jumpers on the small
resistor PCB 1150634, fitted to CR4 of the control
PCB.
2.0.3
Commissioning/Start-Up
Once the Set-Up procedure has been completed, the
unit is available to operate according to the
requirements of the control signal.
When starting with an empty cylinder, the VAPANET
programme switches in the contactor and feeds water
in until the water reaches the electrodes, and current
starts to flow. Thereafter the VAPANET system will
continuously monitor and control the conductivity by
adjusting the amount of water drained and fed into the
cylinder.
With no demand the LE unit has the right hand light
will flash red the left hand light will be off. When the
demand increases or the unit is switched on the cyl 1
LED will flashing green Amber at rate depending on
the demand input and the actual current drawn, the
actual run current of each cylinder is monitored and
until the actual current has two feed above 95 % the
LED will flash green amber when the current is above
95% for two consecutive feed the light will flash red.
If twin cylinder unit the second cylinder starts in the
same way but only when the demand is above 50% to
unit
2.0.4 Features
Boiler Unit
of
VAPANET
Electrode
The VAPANET system of control is designed to adjust
the function to keep the unit operating in the face of
changing water quality in the cylinder and changing
electrode condition even if, in an adverse operational
circumstance, this results in some reduction in output
while the situation exists.
Foaming protection *
In particular, the VAPANET is designed to prevent the
onset of foaming and to introduce corrective drainage
to keep the unit working.
Automatic switch-off
The VAPANET PCB will stop operating in response to
extreme fault conditions identified as:
Drain Fault STOP (no drain function)
Feed Fault STOP (water not reaching cylinder)
In each case, the display will show the STOP
condition and a Help Message, the User LED’s on the
fascia will indicate the condition see table on page 16.
A warning signal will be available for remote
indication. The STOP condition of a VAPANET PCB
will be cleared via the key pad if a display is fitted or
by pressing the reset button on the fascia – then
switching the unit off and on. THIS ACTION SHOULD
Start-Up Instructions
First check:
a)
That the transformer connection matches

Service Advice
2.1
The water hardness and the humidity demand at site will
determine the effective life of a steam cylinder. Units located
in areas with naturally soft waters will experience the longer
cylinder life, possibly upwards of 12 months in calendar
terms. With hard waters, a more frequent cylinder exchange
must be expected and cylinder exchange 2 or 3 times a year
can be the average situation. The normal scaling up of the
Vapac steam cylinder is outside the Vapac warranty.
2.1.1
Procedure for cylinder Exchange.
1.
With the power connected to the unit, manually drain
the unit, by depressing (and holding) the Run/Off/Drain
Switch to the lower momentary drain position.
2.
Disconnect the Vapac from the incoming electrical
supply by means of the external isolator (disconnect
switch). This should be “locked off” to prevent
accidental operation.
3.
Unlock the access panel, and swing open to gain
access to the steam cylinder.
4.
Carefully ease off (lever) the electrode caps (1& 2). If
the cylinder is to be replaced, care should be taken not
to twist the electrode caps while removing the black
power caps. As the electrodes can rotate in the
cylinder bosses (if the plastic cylinder is hot) and lead to
unbalanced electrical loads.
5.
Loosen the hose clip (1) and disconnect the steam
hose (4) from the top of the cylinder.
6.
Using a twisting movement, lift the cylinder clear of its
seating in the feed/drain manifold and carefully remove
the used cylinder from the unit.
7.
Inspect the feed/drain manifold to ensure to ensure this
is clear of sediment.
8.
The drain pump can be removed for inspection and
cleaning, by following the instructions below.
9.
Component Identification

With the pump back in position, insert the cylinder into
the feed/drain manifold, pushing it down firmly to
ensure it is seated correctly.

10. Reconnect the steam hose.
11. Replace the electrode caps – ensure that the are
replaced in the same sequence as when removed. With
the cylinder full pin towards the front of the unit,
electrode number 1 will be to the left of the white
cylinder full electrode. Electrodes 2, 3, 4 etc will be
sequentially connected clockwise around the cylinder
(from number 1), when viewed from above.

Other Maintenance:
•
Should only be carried out by a qualified
electrician.
•
The steam cylinder should be drained prior to
carrying out any maintenance in the steam
section – This must be done prior to isolating
the electrical supply, i.e. before removing the
front access panel.
•
The unit should be isolated from the electrical
supply before any cover or access panel is
removed.
2.2
2.2.2
The pump is a sealed unit and should
not be dismantled. Instructions for
removal / replacement are as follows
1) Place a bucket below the
pump, to catch any water
remaining in the housing
or pipework.
Service and Maintenance
As the operation of the Vapac is entirely automatic, it
normally requires no attention on a day-to-day basis.
General cleaning and maintenance of the component parts
of the Vapac are recommended at intervals of about one
year, but this is largely dependent upon the frequency of its
use and the quality of the water supply. Where the Vapac is
part of an air-conditioning system being serviced regularly,
the Vapac should be inspected at the same time.
2.2.1
2) Remove the two screws
holding the pump cover &
lift clear.
3) Undo the three screws
holding the pump body to the
feed & drain manifold, and
remove it - any water trapped
in the pump will be released at
this point.
Feed Valve with Strainer
The nylon bodied solenoid valve incorporates a small nylon
strainer which is a push fit in the 3/4" inlet of the valve. With
a new plumbing installation, residual loose solid material in
the pipework could partially block the strainer after start-up.
If for this or any other reason a restriction of the water flow is
suspected (outside of supply pressure considerations), it
would be possible to clean the strainer as follows:Turn off the water supply to the Unit.
Undo the nylon nut connecting
the flexible connection to the
Valve with flow
valve inlet .
restrictor
The strainer can be removed
using ‘long-nosed’ pliers to grip
the centre flange provided on
the strainer for this purpose.
Withdraw the strainer.
Wash and replace it.
Reconnect and turn on water
supply.
Reconnect electrical supply to
allow unit to operate.
Note:
Always replace the
strainer after cleaning as it is
required to prevent material
lodging in the valve seat or
blocking the small flow control
restrictor which is fitted in the
valve.
Drain Pump
4) Fit the replacement pump by
following the above steps in
reverse order. Ensuring that the
O-ring surrounding the impeller
Housing is correctly seated, and
That it mates correctly with the
Feed / drain manifold.

UCP1 valid.
For units fitted with a display, the unit requires factory set-up (Number of Electrodes and
Number of Turns)
For units fitted with a configuration board, the UCP2 and/or UCP3 are not being detected.
UCP1 valid.
For units fitted with a display, the unit requires site set-up.
This state does not occur if the unit is fitted with a configuration board.

Invalid configuration. The combination of UCP1 & UCP2 or UCP1 and the number of turns is
not valid.
At the end of the initialisation process, the LEDs will flash Green, Red, Amber
repeatedly for 10 seconds to check that the LEDs are operation correctly.
Remedy:
1
Check that UCP1 is fitted to plug fitted to CR4 pins 7 & 8 for units with Alpha-numeric
display or fitted to configuration PCB part number 1150634, which is fitted to CR4 if no
display is fitted. See page 16 of manual for more details. Ensure that good electrical
contact is made in each case.
2
a) For units without a display, check that UCP2 is fitted to the configuration PCB (see page
16 of the “Installation, Operation & Maintenance Manual”) and that jumper J2 is set to
“electro boiler” and J1 is set for the correct site control signal.
b) For units with a display, select “factory set-up”, logon using password “2121” and enter the
number of power electrodes and number of times the electrode cable passes through the
current sensing transformer (this information can be found in section 1.5 of the manual
and drawing LZD557 sheet 3 of 3). Please note that this will only be necessary if the PCB is
replaced as a new unit will be sent out with the factory set-up pre-installed.
3
For units with a display: Enter “Set-up unit”, enter the “control signal” type and “site
voltage”, see Alpha-numeric display module operating manual..
4
For units with a display: Once the unit has been “set-up” press ok at the prompt “Apply
changes are you sure *?*” when the unit will exit this state.
5
For units with an Alpha-numeric display: Re-enter “Factory set-up” using password
“2121” and re-enter the correct “number of power electrodes” and “number of turns”
information, following the on screen prompts
For units without a display: Check that UCP1 & UCP2 are securely fitted to the
configuration PCB.

Fault stop: Once the problem has been cleared the fault can be re-set by one of the
following procedures.
i) Units fitted with an Alpha-numeric display: Power the unit right off, using the local
isolator (not the unit on/off switch), waiting ten seconds then re-applying power. When the
message “Cylinder x drain fault” is once again displayed press the o.k. button, and the unit
will revert back to it’s operational state.
ii) Units not fitted with a display: Power the unit right off, using the local isolator (not the
unit on/off switch), waiting ten seconds then re-applying power. When the constant amber
“drain fault” indication is showing, press the unit “fault reset” button, which is located on the
fascia above the “Vapac” Logo.
4
Service Interval Expired / Low Output: Will be seen if either of the following occur.
i) Service Interval Expired: Seen if the unit has run for a period exceeding the service
interval of 4500 hours.
ii) Low output: Seen if the cylinder has failed to reach 80% of the demand current after 30
hours run, or if the cylinder achieves this, then the current is monitored and an alarm
generated if the current subsequently falls to less than 60% of the demand current for
period of 4 hours run time.
If this indication is seen the cylinder should be inspected as soon as possible
If it is not convenient to carry out this inspection immediately it is possible to
postpone it for a short time.
4-A)
Unit with Display:
When the unit will require servicing, a message will appear on the display and suggest either
to ‘Postpone Fault’ or ‘Service Now’
i)
If you choose to ‘Postpone Fault’, a message will reappear on the display in 120 hours to
service the unit if the fault was due to Service Interval Expired. In the event of Low Output
Fault, the low output timer will be reset and will resurface if the unit fails to achieve 60% of
demand for a period of 4 hours.
When the alarm is repeated, it should be serviced immediately – and not postponed further.
US
29
ii)
If you choose to ‘Service Now’, select the option with the cursors.
Once you choose to ‘Service Now’, DO NOT disrupt the process, as it
performs its default servicing. If the sequence is interrupted, it will have to be
repeated.
4-B)
Unit without Display:
You will once again be expected to choose between either postponing fault, or servicing unit.
i)
If you choose to postpone the fault, press the reset button once. The appropriate cylinder
LED will change to constant “amber” and the external alarm will be reset, allowing the unit
to continue to run without an external alarm for 120 hours run time (5 days) if the fault
was caused by the service interval expiring. In the event of Low Output Fault, the low
output timer will be reset and will resurface if the unit fails to achieve 60% of demand for a
period of 4 hours
When the alarm is repeated, it should be serviced immediately – and not postponed further.
ii)
If you choose to service the unit,
- Press the reset button: This will cause the appropriate LED to change to constant “amber”, the
external alarm to be reset.
- Press the service button again: (this should be within ten seconds of the first push).
- This will cause a “service routine” to be implemented.
Once you chose to service the unit, DO NOT disrupt the process, as it
performs its default servicing. If the sequence is interrupted, it will have to be
repeated.
5) Periodic Flush/Periodic Drain/Manual Drain/Auto Flush in progress
The items below apply to units with Display and without Display
- LED will commence flashing GREEN every 2 seconds
- The drain pump will initiate and drain the cylinder in its entirety.
- Cold water will then enter the cylinder and fill it up.
- The water will then be drained with excess mineral build up on the elements.
- This flushing process will be performed a second time.
6)

Constant output:
i)
Units fitted with an Alpha-numeric display: This is another transitional state, and once
the “constant output period” has expired, the unit will revert to normal “controlled” operation.
The LED indication will automatically revert to the cylinder’s “current state”.
ii)
8)
Units not fitted with a display: Once the testing of the unit is complete, the jumper J1
on the configuration PCB should be removed from the full output position and returned to its
normal operating position.
No voltage input: Check the wiring to CR6 of the “level sense” daughter board (part number
1150633). If the line voltage can be measured here, check the wiring between CR1 pins 5 &
6, of the same daughter board and CR2 pins 13 & 14 of the main control PCB. If this is also
correct then either the daughter board or the main control PCB is faulty. Once the fault has
been cleared the LED indications will revert back to the cylinders “current state”.

When this is activated the unit will operate, at a preset demand level, if the temperature surrounding the unit falls
below a preset level, to prevent the pipe work from freezing.
It is enabled by setting “frost demand” (via keypad/display) to >0 (it I disabled by setting “frost demand” to 0).
However the unit will not operate unless “frost demand” is set above the unit minimum demand level. Minimum
demand level for LE units is 21% and for LEP units it is 10%.
Frost demand is fully adjustable between 0 & 50%.
Timed Drain down.
Used to drain all the water from the cylinder if the unit remains on standby for longer than a preset (but
adjustable) time period.

Symptom
Main Disconnect Power = ON
Power Light = OFF
Display stuck on initializing
-
Display is not operating
-
Manual Drain not working
-
-
Check/Cause/Remedy
Check the right hand side of the transformer (refer to wiring diagram,
5.0), there should be 3 wires exiting the transformer. Wire 1 on
Common, Wire 2 on 120V (drain pump) and Wire 3 on site voltage.
Check power supply fuses F1 and F2 for continuity.
Check that UCP1 is fitted properly on main control board on CR4.
Verify the connection of the legs of the resistor on the white connector
and the connection of the white connector on board.
Verify that the network cable that allows the main board to
communicate with the display board is properly installed. The main
board has a connector on CR11net that connects to the display board
on CR1net.
Check for inadvertent grounding with cables on board.
Verify the network connectors that are fed from the control board are
properly installed, from CR11net on main board to CR1net on display
board.
Verify the fuse on the control board for continuity (Top left side).
Verify if 9V is being fed from second wire on left side of the transformer
to connection 2 on CR1.
Verify 120V on right hand side of transformer leads to drain pump.
Verify J5 jumper on control board is properly plugged on board and
properly connected to the rocker switch on right hand side. Continuity
should be confirmed from left wire of J5 to wire 44, top right side of
rocker switch. Similarly, continuity should be confirmed from right wire
of J5 to wire 43, bottom right side of rocker switch.
On CR5, between terminal 4 and 6, one should read 120V when unit is
not draining and should read 0V when pump is summoned.

-
Check/Cause/Remedy
Verify unit for open circuit (refer to section 1.6.6 and 1.6.7.)
Make sure that on terminal strip, 9-10 are made (jumper) and 11-12
are made (closed circuit for proving switch and high limit humidistat or
jumper across the terminals).
Verify if there is a demand from controller. (For POT, confirm that
terminals 6-8 are a closed circuit. For a sensing head or controller,
confirm that from terminal 6-Ground, there is a +VDC.)
Verify that controls are properly installed in terminal strip, as instructed
in the literature of controls on hand.
Verify correct ‘Control Type’ configured in ‘Setup Unit’. Note: If control
is strictly a sensing head, SH to precede signal type in ‘Control Type’
Check if water supply valve is open.
Check if water fill valve is energized when unit calls for a fill cycle.
Check hoses leading to manifold from tundish cup have no kinks,
leaks, air pockets or obstructions.
Check with an amp clamp that the current going to the first lead to
cylinder from contactor is increasing as expected.
Check connection on daughter board.
Check electrode caps in proper position along with high water sensor
cap.
Check that torroid (current transformer) corresponds to proper lead
going into electrode cap closest to high water sensor cap. Also check if
torroid is properly installed on main control board (CR3 connection 1
and 2).
4.3 Trouble-Shooting with Mid-Life (Fault during Operation)
Symptom
Solid Amber LED
Drain Fault
-
Check/Cause/Remedy
Once the unit goes in drain fault, reset the fault by disconnecting on the
main power, reconnecting the power, and accepting the fault on the
display.
Confirm that the wire going to the pump is tapped on the right hand
side of the transformer at 120V (Wire should be labeled number 2).
Verify if Manual Drain (Push down on rocker switch) works.
If it does not work, verify wiring from J5 to rocker switch (Refer to
wiring diagram 5.0 and section 4.1 Manual Drain Not Working)

If it does work, check the drain line for proper and suggested
installation, including a downward slope and air gap to avoid all backpressures.
If it does work, check the pump and feed/drain manifold for build-up of
minerals.
If this fault occurs in start-up, verify the factory set-up for any
inconsistencies. Particular attention to the number of electrodes, and
number of turns.
Verify the conductivity of the cylinder and the state of the water. If
water tests are taken, and deemed to be highly conductive water, then
corresponding cylinder should be high conductive.
Investigate if any conductive catalyst was introduced to the unit.
Confirm that water supply is open and unobstructed to the unit.
Verify if the fill valve is energized and water can travel to tundish cup
(fill cup) unobstructed.
Verify that the tundish cup spigot is aligned with the hole in the cup and
water is permitted to travel to feed/drain manifold beneath the cylinder,
unobstructed.
Verify that water level in cylinder rises with facility and is not affected
by and back pressure coming from duct or steam distributor. If it is
affected by a back pressure, one will notice the unit will fill into the
drain at the tundish cup.
If unit fills past the high water sensor pin, drain unit and monitor current
in the lead going to an electrode. If the current is not increasing relative
to water level, conductivity with the water is an issue.
If unit fills to the top and low output fault appears, perform tasks as
mentioned in section 3.4 – step 4.
Specialized check of the Solid State Relay
Important: The following check should be carried out by a competent electrician
Equipment needed:
An AC Voltmeter, multi-meter set to full AC line voltage or suitable voltage test instrument.
Procedure:
1) Remove access panels from both the steam cylinder and electrical compartments
2) Ensure that the humidifier has an operational level of water in the cylinder. Switch unit
on and check that the display indicates “Vapac on line”.
3) Apply the voltmeter, set to the full line Voltage, across the output terminals of the SSR
being tested (i.e. the two terminals carrying the cabling to the elements).
Correct Voltmeter Response – oscillating between full and near zero Voltage.
If Voltmeter reads a constant near zero Volts, Check:
a) That the unit is not feeding water – if it is, wait until the feed valve closes and then recheck. The reason for this is that the SSR will hold closed while the feed valve is open).
b) That the control PCB is giving the correct pulsed D.C. signal (approx 5V D.C.) to the
SSR control input terminals.
SSR Replacement:
A faulty SSR should be replaced with an SSR of the same (or higher) Voltage and
amperage rating. Disconnect the unit from the electrical supply. Disconnect the SSR and
undo the mounting screws. The SSR is bedded in thermal compound to assist heat
transfer – it is important that this is cleaned off, and a layer of fresh compound placed
under the replacement SSR, when it is secured in position.
Reconnect the SSR, reconnect the electrical supply and check the SSR function (as
above) before replacing the access panels.
Note: Use proprietary thread locking compound on the line voltage terminals of the
SSR’s.

Steam pipe to have a minimum slope from
the horizontal of 7° or 12% to allow the
condensate to drain back to the cylinder or
trap. NO HORIZONTAL RUNS. NO 90°
ELBOWS.
2
Water condensate tube to slope at 10° or
18% from the horizontal for condensate to
drain back to drain point.
3
Steam pipes which are mounted
horizontally must discharge vertically
upward.
4
Vertically mounted Steam pipes must
discharge horizontally facing upstream
airflow.
5
If the total pressure within a duct air flow
exceeds 2000 Pa and the static is below
2000 Pa then the probe may face
horizontally at right angles to the air stream.
6
Care should be taken to support steam
hose sufficiently such that no kinks are
formed which would flood with condensate
causing the bore of the tube to become
constricted, leading to excessive pressure
in the steam lines.
N.B Standard steam distribution pipes are
manufactured such that any condensate is drained
back towards the Vapac steam cylinder. Reverse
slope pipes are available, and are fitted with a drain
connector, to enable condensate to be taken away to
a suitable drain.

Figure 1 shows the versatility of the steam
pipe / steam hose steam delivery system. It
also indicates where and how condensate
traps / condensate separators should be
used. If the steam pipe slopes such that the
steam connection is lower than the far end of
the pipe, this indicates that a reverse slope
steam pipe is required. This is fitted with a
drain point to allow condensate to be taken
away to a convenient drain.

The duct should be clear of obstructions,
transformations and bends until the steam
has been absorbed into the airflow. Vapac
Humidity Control Ltd. suggest a figure of 1.5
times the estimated absorbtion distance
stated on the “Vapasorb” design sheet.
Which is supplied with the quotation.

Should it be necessary to slope the steam
hose away from the Vapac Boiler, it will be
necessary to fit a condensate separator to
remove the condensate at the lowest point.
This will need to be taken to a suitable drain.
Notes:
1
Steam pipe to have a minimum slope from
the horizontal of 7° or 12% to allow the
condensate to drain back to the cylinder or
trap. NO HORIZONTAL RUNS. NO 90°
ELBOWS.
2
Water condensate tube to slope at 10° or
18% from the horizontal for condensate to
drain back to drain point. A suitably sized
trap will be required to prevent steam from
escaping via the condensate drain
connection.
3
Care should be taken to support steam hose
sufficiently such that no kinks are formed
which would flood with condensate causing
the bore of the tube to become constricted,
leading to excessive pressure in the steam
lines.
