Davey QB SERIES SPA POOL PUMP - Manual (Page 4)

Starting the Pump
To operate efficiently and prevent pump damage there must be a free flow of water
to and from the pump. Before starting ensure that:
- all pipework is correctly sealed.
- the pool/spa water level is at the correct height.
- that all appropriate valves are open and there is nothing preventing the flow of
water through the system.
1. First prime the pump by ensuring that the pump is below the water level of the
spa pool.
2. Connect to the power supply or spa controller as applicable and switch on.
3. Allow the pump to run, so that any air trapped may be expelled.
4. If prime is not established within less than a minute, as evidenced by a strong
flow of water, switch off the pump and repeat the procedure.
Pump Operation
The water level of the spa or spa pool should always be maintained to at least the
spa jets, thus ensuring water is in the pump at all times.
Trouble Shooting
If the pump runs but there is no water flow or water flow is reduced, the
following condition may apply:
1. The pump is not primed. Re-prime as per instruction in ‘Starting the pump’
2. There are air leaks in the suction piping. Check all piping and eliminate leaks.
Air bubbles in the water flowing back to the pool would indicate a leak in the
suction to the pump allowing air to enter the pipework.
3. A leaking pump shaft seal may also prevent operating. Evidence of this would be
water on the ground under the pump.
4. The pump is not able to get water from the pool. Check that the valves to the
pump are fully open and that the pool water level is up to the spa jets.
5. Blockage in the piping or pump.
Never run pump dry. Running the pump with no water may damage the
mechanical seals, causing leakage and flooding. Dry running damage and
associated damage is not covered under warranty.
Failure to undertake regular maintenance may cause damage not covered
by warranty.
Trouble Shooting continued......
If the pump does not operate, the following conditions may apply:
1. The power is not connected. Where a spa controller is used, check to see if the
controller touchpad is illuminated and the pump is connected to the correct AMP
socket. Also check fuses and the main power supply switch
2. Automatic overload is tripped following an overheating period. The pump motor
has an in-built thermal overload which will re-set after the motor has cooled.
Determine the cause of the overload tripping and rectify.
3. Blockage is preventing the pump from rotating.
4. Motor is burnt out - burning smell is evident. Replacement is required.
If you are unable to resolve any installation or operation difficulties with your QB
Series pump, contact the supplier from whom it was purchased or your nearest
Authorised Davey Pool Equipment Service Centre. If any further assistance is
required, contact the Davey Customer Service Centre at the address indicated in
this manual.
Removal of the Pump from Pipework
Should it be necessary to remove the pump, follow these instructions:
1. Switch off the power and remove the plug from the power source.
2. Close the water valves on the pool return and the pump inlet pipework.
3. Remove the discharge & suction barrel unions taking care not to lose the
orings.
4. Move the pipework with the barrel unions attached until the pump can be pulled
clear.
Water Quality
Maintaining balanced water chemistry is important to the life of your spa pool pump.
This pump is designed to be used with Pool & Spa water, balanced in accordance
with Langelier Saturation Index, with a pH level of between 7.2 and 7.8 and is
regularly treated with a chlorine sanitising agent with the level not exceeding 3PPM.
Please consult your local pool shop regularly to have your water tested.
NOTE: If the pump is hard wired into a time clock or another automatic
control, the wiring should be removed by a qualified electrician.
NOTE: When making any enquiries about your Davey QB Series be certain
to quote the model number from the nameplate located on motor.
