Part 2 - The Benefits Of Accu-Tab® System
The Accu-Tab® System offers a number of advantages over other methods of dosing Calcium
Hypochlorite based products into swimming pools or spa water.
•
The unique Accu-Tab® Chlorinators. Patented technology with 4 different sized
chlorinators to handle volumes of water from a small spa of a few hundred litres to
the largest commercial pool of over a million litres.
•
The Accu-Tab System provides accurate and uniform chlorine delivery.
•
The Accu-Tab Chlorinators are guaranteed for life and the chlorinator itself has no
moving parts.
•
The chlorinators can only be used with the 3” Accu-Tab® Blue SI tablets making
handling easier and reducing dust levels and making for Health and Safety benefits
when compared to granular products.
•
Accu-Tab SI Tablets are formulated with a proprietary and patented controlled erosion
agent to provide slow and consistent chlorine release.They are specially formulated to
inhabit scaling in hard water applications.
•
Accu-Tab SI tablets are supplied in 25 kilo plastic drums with an easy to open latch on
the lid.
•
The Accu-Tab chlorinators are designed to operate unpressurised (eg, outlet open to
atmosphere) and such that only the underside of the 3” tablets are eroded to reduce
any build up of sludge.
•
The system has large bore pipework throughout to avoid clogging and alleviate
problems of blocked injectors.
•
Accu-Tab SI tablets have a pH value of pH 9-10 and as such are much friendlier to pool
equipment and surfaces compared to some alternative types of chlorine donors.
•
The PowerBase units that are required for certain types of commercial and below
water level installations are manufactured in the UK, with readily available replacement
stock parts.
•
All significant items on PowerBase units are fitted using unions for easier maintenance.

Chlorinator - Operating &
Cleaning Instructions
Operation
To refill the chlorinator:
1. Wear appropriate personal protective equipment
2. Isolate the chlorinator. Important: Close the inlet valve BEFORE closing any outlet
valve to prevent over-pressurization of the chlorinator.
3. Remove the lid. Wear respirator (be careful not to inhale fumes).
4. Fill the tablet canister with Accu-Tab® Blue SI Tablets, making sure the tablets lay flat.
5. Replace the lid, making sure that the gasket is clean and properly seated in place.
If necessary, use silicon oil to lubricate the o-ring (do not use Vaseline).
To operate the chlorinator:
1. Start the flow through the chlorinator. Important: Open any return isolation valve
BEFORE opening the inlet valve to prevent over pressurization of the chlorinator.
2. Adjust the calibrated control valve to the desired setting. Check the available chlorine
regularly to determine the optimum setting.
3. Adjust the control valve and refill the chlorinator with Accu-Tab Blue SI Tablets
as needed to maintain Free Chlorine levels.
Cleaning
The chlorinator should be cleaned, if necessary, once or twice a year to remove any residual
product that may have accumulated inside the unit. Cleaning may be accomplished by
soaking in a dilute acid solution. Addition of acid will lower the pH of the water. Be prepared to add a suitable pH increaser after cleaning is complete.
Preparation for cleaning:
1. Prepare a dilute acid solution by adding 1/2 kg of sodium bisulphate to 5 litres of water.
ALWAYS ADD ACID TO WATER, NEVER ADD WATER TO ACID. Wear rubber gloves
and rinse all equipment thoroughly when finished.
2. Have a clean, empty container for temporary storage of any Accu-Tab calcium
hypochlorite tablets from inside the chlorinator.

the cleaning process, turn the pump on now. Then open the control valve to flush the
chlorinator for 30 minutes at 5-10gpm (20-40 litres/min).
8. After 30 minutes of flushing, isolate the chlorinator and rinse with water. Drain the
chlorinator by temporarily opening the return isolation valve. Rinse a second time and
drain.
9. Soak the tablet canister in the dilute acid to remove scale. Make sure the holes in the
bottom of the tablet canister are free of residue. Use a pointed instrument to clean
them, if necessary. Rinse with water. Cleaning is now complete.
Returning the chlorinator to service:
1. After cleaning is complete, re-install the tablet canister and refill the chlorinator with the
tablets from the temporary storage container. Add fresh tablets if necessary to bring the
tablet level to a full charge, ensuring that the tablets are laid flat.
2. Secure the lid, making sure that the gasket is clean and properly seated in place.
3. Open the return isolation valve.
4. Open the inlet isolation valve; adjust control valve.
Remember to check the pH of your pool or spa water. With the addition of acid during the

Accu-Tab® PowerBase
The simple principles of the Accu-Tab® range of feeders – large bore pipework, large water
flows, the outlet pipework a larger size than the inlet pipework – is extended into the
Accu-Tab PowerBaseTM unit.
Assembled onto a robust aluminium frame made in the UK from ‘off the shelf’ standard
components generally available from Certikin International Limited, or from leading plumbers
and electrical merchants.The system has PVC socket unions on either side of all significant
components for easy maintenance or replacement.
Which installations require a PowerBaseTM?
An Accu-Tab® PowerBaseTM is required where the pool or spa plant room is BELOW pool
water level. If an Accu-Tab feeder cannot be sited above pool/spa water level and dosed by
gravity into a balance tank, then an Accu-Tab Powerbase must be used.
How does a PowerBaseTM work?
The pool circulation water pipework is tapped, usually post filter, to give a 11/2” (or 50mm)
supply into the PowerBase at the three-way tee-piece. It is suggested that an inline ‘Y’
strainer is fitted in the supply line, preceded by an isolation valve. At the three-way tee piece
the PowerBase diverts some of the water into the water tank via the ball cock to give a
continuous flow of water to the tank.
The rest of the water to the PowerBase tee-piece is diverted up via the solenoid valve into
the feeder; via a control valve and flow-meter.This water flows across the underside of the
tablets picking up a little chlorine, which thus feeds chlorinated water via a large diameter
pipe, under gravity, into the tank to mix with the water supply via the ballcock. An upper
level switch to prevent the tank over-flowing due to excess inward water supply will
automatically close the solenoid valve. A second, but ‘low-level’ float switch is fitted to the
tank to switch off the pump to prevent the pump running dry.
The booster pump outlet is fitted with a top quality non-return valve to prevent pool
circulation water flowing back into the pump if it is switched off. It is suggested that a second
in-line ‘Y’ strainer is also fitted to prevent dirt from entering the non-return valve.
A 11/2” ball valve is supplied and should be fitted at a convenient point, after the non-return
valve, to throttle the pump outlet water to help balance the system water flow of the
PowerBase, where it returns chlorinated water to the main pool circulation system. This
prevents water leaving the tank faster than it is supplied.
An optional electric delay timer may be fitted in the control box if the pump requires a
larger operating cycle.
16
How does the PowerBaseTM differ from other cal hypo systems?
Unlike any other system that makes a chlorine solution from calcium hypochlorite, a solution
of around 200ppm is generated in the tank using only large bore pipework and big flows of
water. This prevents scale build up which with other systems in the past has led to blocked
injection points. The PowerBase does not use injectors. The simple design and operation of
the PowerBase means that such blockages are avoided. Problems have been designed out:The
Accu-Tab® Powerbase is better by design.
How much room will the PowerBaseTM need in the plant room?
The 3012 PowerBase is supplied on an aluminium frame approximately 92cm long x 66cm
wide and 61cm high (plus feeder height 66cm).
The 3075 and 3150 PowerBase are supplied on an aluminium frame approximately 122cm
long x 61cm wide x 61cm high (plus feeder heights 61cm for the 3075 and 66cm for the
3150).
What comes with a PowerBaseTM?
The PowerBase comes complete with:
• Accu-Tab® Chlorinator
• 3/4 hp booster pump
• Solenoid valve
• Translucent tank and lid with float valve and high and low level float switches
• Angle seat check valve
• 2 No in-line ‘Y’ strainers
• 1 1/2” gate valve
• Control valve and flowmeter
• Interconnecting pipework (grey PVC)
• Electrical connection box
• Full installation manual
Note that the feeder, which contains the Accu-Tab® SI tablets, is not under pressure, so there
is no need to consider the Pressure Vessel Regulations of 1995/2002.
All electrical components are C.E. Rated and the control box is IP55 rated. A wiring diagram
is shown on page 21 and the unit is ready to wire up to an automatic controller where
required.
Isolation valves (not supplied) should be fitted on the feed to and the return from the
PowerBase.
17
Accu-Tab PowerBase Installation,
Start-Up and Balancing Instructions
18
1.
Locate Chlorination System in adequately ventilated area of Plant Room and on level ground
preferably away from other Electrical and Auto Dosing Equipment. If system is in area subject
to standing water, then system should be raised above standing water. Adjust, levelling feet as
necessary.
2.
All systems are tested in full operation at the factory, however fittings may loosen during
shipping. Before Installing System, hand tighten all fittings on valves, check valves and
unions.
3.
Tap into the pool circulation system, and add isolator valves (not supplied) for subsequent
servicing of the Accu-Tab chlorination system. The preferred connections are before the
heater for the feed to the PowerBase and after the heater to return from the PowerBase.
4.
Use 1.5” diameter minimum piping on the PowerBase inlet and outlet piping to ensure ample
supply of water. The 1.5” gate valve should be installed downstream of the Angle-Seat check
valve (N.R.V.) on pump outlet. The N.R.V. is installed in a convenient position (with optional
Y-strainer preceeding it) after the pump outlet, clear of electrics to allow safer cleaning of
it. (Refer to the charts at the end of these instructions for the minimum required system
supply water flow rate.) Use isolation valves (not supplied) at main system connections. Do
not use the gate valve provided for this as it is only intended to be used as a
pump discharge valve. An (additional) in-line strainer can be useful on the inlet to the
PowerBase to prevent ingress of grit/sand to the system and thus to reduce possibility of
Solenoid Valve being blocked open.
5.
A qualified electrician is required to make connection
to the IP55 rated junction box on the Powerbase. Access
holes should be made in the box to suit site. Any controller
should be connected as shown on the wiring diagram.
(page 21)
All Electrical work to comply with current regulations
(eg 16th Edition I.E.E. Regs) with special
consideration to use of R.C.D.
Note that the frame of the PowerBase must be
bonded to Earth.
6.
Once the electrical power and pool water input and
output connections are in place, start the pool
circulation system. Verify that system is operating properly. Then open isolation valves that
feed to and from the PowerBase and check for leaks. Supply water will begin filling the tank
through the float valve. Do not as yet add any Accu-Tabs to the feeder. Water should
begin to fill the tank through the float valve, and the water level should rise to a level and then
stop as the float valve shuts off.
7.
Open the isolator valve on the discharge side of the chlorination unit, and open the gate valve
on the pump discharge about 1/4 open. The non-return valve (check valve) should prevent
back flow into the tank. If the level in the tank increases, close isolator valve, and inspect NRV
(check valve) for debris. If debris is a regular problem in the system, the consider using an
in-line strainer before NRV, if not already installed.
8. Close the valve that controls water flow to the chlorinator.
9.
Turn system on using the automatic
chemical controller (if any) to open
solenoid valve and start the pump. The
level should again stabilise as water is
added by the float valve.
10.
Open chlorinator inlet valve and set at
desired flow rate.
19
11.
Slowly, and in small increments, continue to open the pump discharge gate valve, and adjust
chlorinator inlet valve as necessary to get desired inlet flow. If water level in tank becomes too
high, the high level float switch will close the solenoid valve until the level drops.
12.
Continue to open gate valve on pump discharge until tank level appears as though it will go
empty, and begin closing gate valve to stabilize the water level. If tank goes empty, and pump
loses prime, de-energize the control circuit, and wait until float valve fills the tank. Begin the
procedure again at step 9. (NEVER LET THE PUMP RUN DRY)
13.
Adjust the flow to the chlorinator as necessary according to the chart, using grey calibrated
valve (3012), or inlet Gate Valve (3075 and 3150).
14.
When the water level is stabilized at about 1/2 - 3/4 level in the tank, the flows are balanced.
15.
If tank level rises or falls, make adjustment to the gate valve on the pump discharge.
16.
Shut down chlorination unit by closing solenoid valve. Water will drain from the chlorinator,
and water level should stabilize.
17.
(a)
If level continues to increase, shut the discharge isolator valve. If level stops increasing,
inspect the check valve for debris.
(b)
If the level continues to rise, shut the inlet isolator valve, and inspect the solenoid for
debris.
Turn the system OFF and ON several times, allowing it to operate for several minutes
each time. Check all connections for leaks, make sure the delivery pump suction always
remains covered with water.
Note:There is a low level float switch that will turn off the pump if the water level is too low.
If water fill is too slow, then a “delay timer” can be added to the control box to prevent the
pump “hunting” or if the feeder is on a very lightly used spa or pool.
18.
Put on appropriate Personal Protective Equipment (PPE) eg gloves, goggles etc.
19.
To begin chlorinating, remove the chlorinator lid and half fill the Chlorinator with
ACCU-TAB® Blue SI tablets.
20.
Check the system daily for leaks and proper operation of all components.
21.
Adjust the flow rate through the chlorinator by adjusting the inlet valve.

Troubleshooting Guide
Solution Tank Levelling: Possible Causes.
a) Tank level runs low causing the pump to lose prime or low-level-switch to
turn it off.
This is caused by the pump moving more water than is fed to the system. This can lead to
inconsistent chlorine residuals, and can lead to premature pump motor failure. Follow the
procedure to adjust:-
b)
c)
1.
Slowly, and using small increments, close the pump discharge gate valve.
2.
Make incremental changes to the discharge gate valve until the tank water level rises
and stabilizes, and is approximately at 1/2 to 3/4 tank level.
3.
A further option is the use of a delay-timer in the control box so that if the low level
switch turns the pump off and then water level in tank rises but pump comes on again
and quickly pumps it out, then if these cycles are too short, with the pump turning on
and off quickly, then the addition of a delay timer enables, a long period (eg 15
minutes) to be set before the pump switches on again.
Tank level runs high causing the solenoid to close due to high level float switch.
This is caused by either too high a flow through the chlorinator, or the discharge valve is closed
too much. Follow the procedure to adjust:1.
Slowly, and using small increments, open the discharge valve.
2.
Make incremental changes to the discharge valve until the tank water level drops and
stabilizes, and is approximately 1/2 to 3/4 tank level.
3.
If level will not drop, begin reducing the water flow to the chlorinator. If this results in
low chlorine residuals, contact Accu-Tab specialist for assistance.
Tank fills and continuously overflows when system shuts down.
A.
Solenoid has failed.
1. Shut inlet isolation valve to verify that it is the solenoid.
2. Disassemble the solenoid to check for debris
3. Reassemble the solenoid, and open isolation valve.
4. If overflowing continues, replace solenoid valve.
B.
Check-valve (Non-return Valve) on pump outlet has failed.
1. Shut outlet isolation valve to verify that it is the “check valve”.
2. Disassemble the “check” valve (NRV) to check for debris or scale.
3. If scale is present, clean with a dilute acid solution.
4. Reassemble the “check” valve (NRV) and open the isolation valve.
5. If overflowing continues, replace check-valve/or use an In-line Strainer.
23
d)
Tank fills and overflows slightly, then stops
Level in the solution tank is too high during operation. Refer to “Solution Tank Levelling” in the
“Operating and Maintenance Instructions” section of this manual.
e)
Tank continually runs low level/empty, causing pump to lose prime, or low
level-switch to turn it off.
A.
Float Valve not operating properly.
1. Remove solution tank lid and verify that float is free to move up/down.
2. If the float is in the up position, and cannot be freed, replace float valve.
B.
Solenoid Valve failure
1. Check flow rate on flow meter.
2. If no flow, then contact Accu-Tab Dealer.
C.
Improper tank levelling.
1. Refer to “Solution Tank Levelling” in the “Operating and Maintenance Instructions”
section of this manual.
Please contact Accu-Tab Dealer for further troubleshooting assistance.
