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.
Unscrew the strainer basket lid knob anti-clockwise and remove the lid. Prime
the pump by filling the strainer basket area with water. Replace the lid,
ensuring that the sealing ring is clean and located flat side down in the casing
groove. Tighten the lid by screwing knob clockwise.
Firm hand-tight only is
required.
2.
Connect to the power supply and switch on.
3.
Allow the pump to run so that any trapped air may be expelled.
4.
If prime is not established within approximately two minutes, as evidenced by a
strong flow of water, switch off the pump and repeat the procedure. Continued
evidence of air under the strainer basket lid indicates an air leak in the suction
piping or lid gasket which should be rectified.
Pump Operation
For optimum pump performance, the strainer basket housing should always be full
of water and free from air bubbles. The water level of the pool should always be
maintained to at least halfway up the skimmer box ensuring water is in the pump at
all times. From time to time it may be necessary to re-prime the pump. This should
be carried out as described above.
Emptying the Strainer Basket
The strainer basket should be inspected frequently through the transparent lid and
emptied when a build-up of rubbish is evident. The directions below should be
followed:
1.
Switch off the pump.
2.
Unscrew the strainer basket lid knob anti-clockwise and remove the lid.
3.
Remove the strainer basket from its housing.
4.
Empty the trapped refuse from the basket. Hose out with water if necessary.
5.
Replace the strainer basket such that it locates in the lugs at the top and bottom
of the housing.
6.
Replace the lid ensuring that the sealing ring is clean and located flat side down
in the casing groove. Tighten lid by screwing knob clockwise.
Firm hand-tight
only is required.
7.
Orings and gaskets should only be lubricated with a lubricant suitable for nitrile
rubber. No other sealants are required.

Trouble Shooting
If the pump runs but there is no water flow or water flow is reduced,
the following conditions may apply:
1. The filter requires backwashing or it is blocked. Refer to the relevant
section in the filter manual.
2. The pump is not primed. Re-prime as per instructions in “Starting the
Pump”.
3. There are air leaks in the suction piping. Check all piping and eliminate
leaks, also check for a loose strainer basket lid. 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.
4. A leaking pump shaft seal may also impair operation. Evidence of this
would be water on the ground under the pump.
5. 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 levels is up to the
skimmer box.
6. Blockage in the piping or pump. Remove the strainer basket and check
for any blockage to the pump impeller entry. Check the skimmer box for
blockage.
If the pump does not operate, the following conditions may apply:
1. The power is not connected. Check the power point by plugging in a
portable appliance to ensure power is available. Also check fuses and
the main power supply switch.
2. Automatic overload is tripped. The pump has as in-built thermal
overload which will re-set automatically after the motor has cooled
following an overheating period. Determine the cause of 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
Davey Pool Pump, contact the supplier from whom the pump was
purchased or your nearest authorised Davey Pool Equipment service
dealer. For assistance in locating your nearest dealer contact the Davey
Customer Service Centre. For professional after sales service or repair
contact your Davey Dealer.

Removal of the Pump from Pipework
Should it be necessary to remove the pump, the following procedures should
be followed:
1. Switch off the power and remove the plug from the power point.
2. Close the water valves on the pool return and the pump inlet pipework.
3. Undo the barrel unions taking care not to lose the orings.
4. Lift the pipework with the barrel union attached until the pump can be
pulled clear.
Water Quality
Maintaining balanced water chemistry is important to the life of your pool
pump. This pump is designed to be used with Pool & Spa water, balanced
in accordance with Langlier 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 3000PPM.
Please consult your local pool shop regularly to have your water tested.
NOTE:
If the pump is wired into a time clock or other automatic control, the
wiring should be removed by a qualified electrician.
NOTE:
When making any enquiries about your Pool Pump be certain to quote the
model number from the nameplate located on the top of the electric
motor.
If water is seen to be leaking from the pump or fittings, have the pump
serviced immediately. Failure to fix water leaks can cause damage to the
pump not covered by warranty.
Never run the 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.
DANGER - Hazardous suction. Do not block water entry into filtration
system with any part of your body as the pressure can trap hair or body
parts, causing severe injury or death. Do not block suction. Turn off
pump immediately if someone becomes trapped.
Caution! Do not add chemicals directly to the pool skimmer. Adding
undiluted chemicals may damage pump and filter and void warranty.
Small children using the pool or spa must ALWAYS have close adult
supervision.

Routine Maintenance tasks – to maximise the life of your pool equipment
& personal safety, use this checklist once a week. Turn pump off first.
a. Make sure that any pressure gauges are in working condition and the
operating pressure is within limits as specified on the product.
b. Make sure that each suction inlet, and main drain has a cover that is
securely attached and in safe working condition.
c. Make sure that all skimmer covers are securely attached and in safe
working condition. These should be replaced every 3 to 4 years.
d. Remove any obstructions or debris from the main drain cover.
e. Ensure the skimmer baskets and the pump hair and lint pots are free of
leaves and debris at least once a week.
f. Remove obstructions and combustibles from around the pump motor.
g. Make sure all wiring connections are clean and that all wiring and electrical
equipment is in good condition. Damaged wiring must be repaired or
replaced by a qualified electrician as soon as damage is discovered.
h. Check water balance and sanitiser levels at your local pool shop.
WARNING! Pump suction is hazardous and can trap and drown or
disembowel bathers. Do not block suction. Do not use or operate
swimming pools, spas or spa baths if a suction cover is broken, missing
or loose. Two suction covers and inlets must be provided into every pump
to avoid suction entrapment.
