FUSES

The system and its supply/interconnecting wiring must be protected by fuses, preferably High Rupture Current (HRC) motor rated types (EN60269) or miniature circuit breakers (EN60898) or local codes having similar time lag characteristics, that allow starting of the compressor yet still afford close overcurrent protection under running conditions. The ratings below are for HRC motor rated fuses.

DXD/DXDH FAN COIL UNIT INSTALLATION

TEV DXD/DXDH Fan Coil Units are designed to be installed within a ceiling void. Air discharge should be via insulated ducting, connected to 200mm diameter spigots (250mm diameter spigots also available) and to appropriately sized discharge plenums/grilles. Ducting and discharge facilities are supplied by others and are not included with the fan coil units. Similarly, return air arrangements, via ducting or to the ceiling void, must also be provided.

The installer must ensure that the mounting suspension points are capable of supporting the operating weight of the unit,

(refer to the table below).

UNIT FIXING

NOTE: All kits should be fitted prior to hanging the unit and connecting the pipework.

1.

Before lifting the unit into position, mark out the four outer fixing points as shown below, and fit suspension rods of appropriate length and diameter, (minimum recommended thread size M8); two inner central fixing points are available for installer convenience. DO NOT lift the unit by its spigots, drain tray or electrics box when raising it into position.

SUSPENSION MOUNTING

The installer must supply 4 x M8 threaded rods with 16 nuts and washers to suit.

IMPORTANT:

The stabilizing brackets provided MUST be used when suspending a unit.

Fit the stabilizing brackets to the top corners of the backpanel and front face using the No. 10 screws provided, (2 per bracket).

If these brackets are omitted the unit will be subject to unacceptable movement on compressor start

(Fig. 2).

Where long drops of M8 rod are used, it is advisable to incorporate flexible pipes in the suction and expansion lines.

Using the template printed on the side of the packing carton, (centres marked A), mark out the ceiling and drill 4 holes to suit M8 screwed rod, (see

Fig. 1). Raise the unit to the required height and pass the screwed rods through the mounting holes in the units feet and stabilizing brackets. Secure the unit with a nut and washer on either side of each stabilizing bracket and two nuts and washers underneath each foot mounting hole, (Fig. 2).

Fig. 2.

WALL MOUNTING

Wall mounting brackets are available as an optional kit (53200407).

CONDENSATE DRAIN (DHPUE)

The DHPUE coil will act as an evaporator during the heating cycle and create water. A condensate drain must be fitted.

Remove the plate from the valve end mounting foot and fit a

22mm ID hose to the copper stub.

Route the hose through one of the knockouts.

A 5m head condensate pump kit (54300452) is available for applications where gravity drain is not possible.

DUCTWORK

Each unit is supplied with air inlet and discharge spigots:-

Models 15- 40: 354mm (14") Ø Models 50-80: 404mm (16") Ø.

These may be used for connecting installers ducting or with the optional duct, plenum and grille kits (refer to the kit instruction for installation). The front face of the units are fitted with M6 rivnuts to accept square ducting (shown below). Maximum flange width is 25mm and fixing holes should be central within them.

NOTE: It is essential that ducting is adequately insulated to prevent sweating, (both inlet and discharge ducts on

DHPUE models). An insulation thickness of at least 45mm is recommended.

APPLICATION - ALL CONDENSING UNITS

1.

To maximise performance, pipe runs should be kept as short as possible, avoiding sharp bends. However, individual pipe runs to a maximum of 80m, including 20m lift, are permissible provided good refrigeration practice is followed.

Published performance duties are based on 7.5m pipe runs. Correctly sized pipes for each installation, and fitting the correct expansion orifice (restrictor) will result in no significant loss of capacity on extended pipe runs.

a) Pipe sizes are based on:-

Minimum of 3.8 m/s (750 fpm) suction gas velocity for horizontal or downflow.

Minimum of 7.6 m/s (1500 fpm) suction gas velocity for upflow.

Maximum of 15.2 m/s (3000 fpm) suction gas.

b) Where vertical risers exceed 3m, oil traps must be formed in the pipe. This will help ensure that oil returns to the compressor. Typically fit an oil trap every 3m with a trap at the bottom of the riser.

2.

Add 25 grams of POE (polyolester) refrigerant oil (obsolete units fitted with rotary compressors contain PVE oil and require no extra charge) for every 350 grams of charge added to systems with pipe runs exceeding 25m, up to a maximum of 300 grams; preferably by slowly pumping into the suction side with the unit running, after charging the system.

3.

The maximum pipe lengths to be used for each pipe size and outdoor unit are shown in the table opposite. Use of these sizes and lengths is recommended in order to achieve optimum system performance.

In calculating equivalent lengths of pipe runs, the effect of bends and fittings must be taken into account. The table below covers the fittings most likely to be encountered in this type of installation. The equivalent lengths of all the fittings in a particular pipe run must be added together and the total added to the actual length of pipe in the run, in order to calculate the total equivalent length.

NOTE:

Ensure that both service valves on the outdoor unit are closed (IN, fully clockwise) before commencing installation.

Indoor units have a low pressure holding charge of nitrogen, which may be released into the atmosphere without damage to the environment. This should be done prior to making pipework connections.

2. Outdoor units are delivered with restrictors fitted - determine if a change is needed by reference to the above tables.

3. MHPUE 15 - 90/DHPUE are supplied with 2 expansion assemblies. One (cooling) is fitted to the outdoor unit and one

(heating) is supplied loose to be fitted at the indoor unit, in the expansion line. For any change of restrictor, reference must be made to the tables above.

a.

When installing a heat pump system, the second expansion assembly (140mm long) must be fitted to the expansion line as close to the indoor unit as possible. This provides throttling of the refrigerant and eliminates the need for separate check valves.

b.

Remove the flare nuts from the suction service valve and the expansion device as appropriate.

c.

Ensure that both the suction and expansion lines are fully insulated.

d.

Place the flare nuts over the incoming pipework and flare the pipe ends. The use of a little refrigeration oil on the flaring tool will help.

e.

Connect the pipework between the units. Do not leave pipe ends, valves etc. open to the atmosphere. Always use two spanners when tightening the flare nuts to avoid twisting the pipes. Use a small amount of refrigerant oil on the mating surfaces.

f.

Sight glasses and filter driers are not necessary, but if required should be fitted between the outdoor unit liquid shut off valve and the expansion device.

4. For units supplied with an alternative restrictor, replace the restrictor in the outdoor unit by:

a.

Completely removing the expansion assembly from the outdoor unit.

b.

Split the expansion assembly in the middle.

c.

Remove the existing restrictor.

d.

Drop the new restrictor vertically downwards into the field connector.

e.

Reassemble in the vertical plane (field connector lowest) and refit the expansion assembly to the outdoor unit.

ELECTRICAL CONNECTIONS

Mains, control and interconnecting cables must be supplied and fitted by the installer.

Installer wiring must be carried out in accordance with local and national codes.

Refer to the interconnecting wiring diagrams on pages 32 to 36.

Mains supply cables must be size compatible with the recommended fuse for a given system (see page 13).

An all pole isolator switch should be positioned within easy reach of the indoor unit.

The equipment must be earthed.

Cable clamps for use with stranded cables are supplied in units 15 - 90 and should be used to secure all incoming/outgoing cables. Installers must supply a method of securing any solid sheathed cables.

Systems require a supply to the outdoor/ducted unit with connecting cables run to the indoor unit.

SCROLL COMPRESSOR ROTATION

On 3 Phase unit sizes 50 to 200 it is possible for the scroll compressor to run backwards. This becomes obvious on start up; the compressor will not develop a normal running pressure differential and the top will not become warm. It may be excessively noisy. If this happens, switch off the mains power and exchange any two of the phases supplying the unit. This will correct the rotation of the compressor.

Fax: 01823 665807


OUTDOOR UNIT WIRING

Cable entry for the outdoor unit electrics is through the cabinet to a terminal block.

MCU+, MHPUE, DCUE and DHPUE units are supplied wired via a head pressure controller to give maximum control. Ensure that all connections are secure and that both units are earthed.

MCU unit fan motors have a high speed (black) wire and a low speed (red) wire; the speed not being used is wired into a dummy terminal. They are supplied wired for low fan speed, which is suitable for temperate climates. If continuous running is expected at ambient temperatures of 35°C or higher, change to high speed by interchanging the black and red wires, i.e. black to fused terminal, red to terminal 4 (single fan units) or terminals 4 and 8 (double fan units).

DATA PLATES

Because of the ability to mix-match indoor and outdoor units, the data plate only gives information on outdoor units.

To obtain the system details, input power and currents from indoor and outdoor units should be added together. Data plates show basic units with electric heater kit loads shown separately.

FIRE LINK

In order to automatically switch off the fan in the event of a fire, it is necessary to fit an external switch (240V, 3A, closed to run, volt free contact) between terminal block terminal 14 and the TEV remote control thermostat terminal

1. This switch should be operated by the building's fire alarm or BMS system.

EVACUATING

Connect a vacuum pump to the service ports on the outdoor unit valves and evacuate the interconnecting pipework and indoor unit to 1000 microns (1 Torr) or better and allow to be held for a minimum of 15 minutes.

ADDING REFRIGERANT

1.

After evacuating the indoor unit and interconnecting pipework, open the valves using a 4 or 5mm Allen key. The high and low side pressures should equalise within a minute.

2.

Additional charge for all systems, including heat pumps, should be introduced with the system in the AIR

CONDITIONING MODE.

3.

If a manual HP cutout is fitted, ensure that the reset button is depressed.

4.

On MHPUE/DHPUE models a random start delay of up to 1 minute occurs when mains is first applied. A 3 minute delay occurs between successive compressor operations on all systems incorporating MHPUE units, or MCU/MCU(+) units fitted with a 3 minute timer kit.

5.

Additional charge should be introduced through the Schrader valve on the indoor unit or the service port on the suction service valve on the outdoor unit (see charging section below to calculate the weight).

6.

MHPUE/DHPUE are supplied with link JP6 fitted on the outdoor unit pcba; this allows additional charging and overrides alarms during the charging process. With both units powered, the MHPUE fans will run at high speed. Set the DXD(H) unit to operate in cooling mode at maximum speed. MCU outdoor units should have a speed appropriate to their expected operating ambient. On MCU+ units transfer the blue wire(s) from fan speed control terminal 4 to

terminal 1 during charging and return to 2 (4) on completion.

7.

Ensure that the refrigerant being added is the same refrigerant that the system was factory charged with.

8.

Run the system for a few minutes to allow it to stabilize.

DXD/DXDH SYSTEMS - PIPE RUNS BELOW 7.5m:

UK conditions: Each outdoor unit is precharged with R22/R407C to give the correct system charge with pipe runs up to 7.5m.

Additional oil is not required.

NEMA conditions: add refrigerant as shown on page 21

DXD/DXDH SYSTEMS - pipe runs over 7.5m.

For pipe runs above 7.5m, extra refrigerant and oil must be added by the installation engineer for each additional metre over 7.5m, based on the following: (if charging for NEMA conditions, , add the charge shown on page 21 as well as for extra length)

Expansion line size.

Additional R22 (g/m).

Additional oil.

25g per 350g of additional R22/R407C to a maximum of 300g

Typical charge to be added for longer liquid lines: 1/2" OD add 80 gms/m; 5/8" add 110 gms/m.

Typical suction pressures on short lines at UK conditions, with high speed evaporator fan, low speed condenser fan

(commissioning speed for MCU+ and MHPUE), should be; Electromechanical Comfort Systems approx. 4.4 bar (65 psig);

Electronic Comfort Systems approx. 3.8 bar (55 psig); Heat Pump Systems approx. 4.0 bar (58 psig).

9. On MHPUE units, once refrigerant has been added, REMOVE link JP6, identified by a white label (otherwise the unit will always run at full speed).

WHEN INSTALLATION HAS BEEN COMPLETED - CHECK :-

1. All pipe work and joints for leakage.

2. All pipe work and fittings for insulation.

3. All bolts are secure and that the fan rotates freely.

DXD WIRING DIAGRAM

TESTING THE PUMP AND CONTROL a b c

DXDH WIRING DIAGRAM

Connect a suitably fused supply to the unit (refer to the unit installation instructions). Allow approximately one minute for the controls and sensor to stabilize.

Slowly add water to the condensate tray sump until the pump runs. Initially the pump will be noisy until the air in the hose has been expelled. It is possible that, on this first cycle, the pump will run dry for a short period

(indicated by noise). This will not harm the pump unless it is run dry for a longer period.

Add more water to the sump and the pump will cycle in the normal manner.

d

With the system in cooling mode, continue adding water to the sump until it reaches the higher of the sensor probes. The cooling cycle will shut down, and the pump continue to run, until the water has dropped below level of this probe. Cooling will restart automatically depending upon demand.

the

NOTE:

Whenever the electrical supply to a unit fitted with a condensate pump and controls is interrupted, a delay of at least 1 minute will occur before the pump will start after the supply is reinstated.

TROUBLE SHOOTING

Unit will not cool

Pump does not run

Cooling is interrupted

circuit

Excessive pump noise

No mains supply to the control board.

The fuse on the pcba has failed (315 mA x 20mm)

Sensor is disconnected from the control board

Restriction in pump flow allowing the condensate level to rise and trip the overflow

- check for blockage or kink in hoses.

Condensate at high level -- tripping overflow circuit

Pump filter blocked - remove, clean and replace

Air leak in hoses and/or joints

Pumping without water in sump -- control board fault

Loose connection between the sensor and the control board

Loose fuse, intermittent mains supply to the control board

Water syphoning due to lack of an air break in the outlet from the pump

APPLICATION NOTES

1

The pump will work against a 5m head. Flow rate is highest with minimum head.

2

Long drains should not be exposed outdoors, as condensate may freeze and block the drain in winter.

3

Ensure that there are no kinks in any of the drain hoses as this could seriously affect the pump performance.

4

Avoid having the drain outlet more than 200mm below the level of the pump, otherwise syphoning may occur, giving rise to noisy pump operation. Avoid this by fitting an air break eg. by pumping into a larger diameter pipe than that

5

Clean the filter at regular intervals.

It is preferable to fit this kit prior to installing the unit, the following refers to bench fitting.

ISOLATE THE SYSTEM ELECTRICALLY PRIOR TO INSTALLATION OF THIS KIT

The 1 and 2kW heaters fitted to DXD 20 and 30 are single bent elements fastened at the electrics box end, whilst the

2.5kW fitted to the DXD 50 is a single straight element supported by a bracket at either end which is secured through the side panel. Unit sizes 60 to 130 are similar to the size 50, but in this case have two straight elements each of 2kW.

In addition to fitting of the elements, assembly of the kit involves fitting of a manual overheat cutout, routing the capillary to suit the size of the unit, fitting a relay and MCB, routing and making electrical connections.

ASSEMBLY

1 PREPARE THE UNIT

Lay the unit on its backplate on a bench and remove the access panel, drip tray and electrics box cover.

2 ELECTRICAL FITTINGS

Fit the relay bracket and relay.

Secure the terminals and MCB onto the DIN rail in the electrics box.

3 MANUAL CUTOUT AND CAPILLARY CLAMPS

Fit the manual cutout to the unit by making a small hole in the insulation and passing the capillary through the 30mm hole in the electrics box. Position the capillary underneath the clamps already fixed inside the unit, (see the diagram overleaf for bending to shape for each unit).
