Location

The pump should be located as close to the water as practicable and mounted on a rm

base in a well-drained position, high enough to prevent any ooding. It is the installer’s

responsibility to locate the pump such that the nameplate can be easily read and it can

be readily accessed for service. The four holes in the base shall be xed on the ground

(alternatively, this can be with a rubber pad and/or mounting frame) after installing the pump.

Weather Protection

It is recommended that the pump is protected from the weather.

Power Connection

IMPORTANT INFORMATION: Your Davey pump is Double Insulated to Water Circuit. If

equipotential bonding structure is required, then a Equipotential Bonding Point is provided.

(Please refer to your local statutes and regulations for AS/NZ 3000 Wiring standards).

Davey SureFlo pool pumps are suitable for connection to a nominal 240 volt 50Hz power

supply and are equipped with a ex lead and 3 pin plug. If a power outlet is not available

within 3 metres of the pump, a 3 pin power point in a safe, dry place may need to be

provided by an electrician. Extension cords are unsafe around pools – and should be

avoided. If the supply cord of this product is damaged it must be replaced by the Dealer or

manufacturer, with genuine Davey spares.

Davey Water Products recommends that all installations are tted with

earth leakage or residual current protection devices.

CAUTION: In the interest of safety, we advise that all brands and types of pool

pumps must be installed in accordance with AS3000 wiring rules or equivalent.

In accordance with AS/NZS 60335.2.41 we are obliged to inform you that

this pump is not to be used by children or inrm persons and must not be

used as a toy by children.

Power supply to this pump needs to be through an isolating transformer

or RCD, having a rated operating current not exceeding 30mA.

If the pump and lter are located below pool water level, it is necessary to

t isolating valves in the pipe between the pump and the skimmer box and

in the return pipe between the pump and the lter.

The ttings on this product are constructed of ABS. Some PVC jointing

compounds are incompatible with ABS. Check compound suitability

before use.

CAUTION: In order to avoid a hazard due to inadverdant resetting of the

thermal cut-out, this appliance must not be supplied through an external

switching device such as a timer, or connected to a circuit that is regularly

switched on and off by the utility.

WARNING! Ensure that an electrical isolation switch is located with easy

access so that the pump can be turned off in an emergency.

Pipe Connection

A set of self-aligning barrel unions are provided for connecting to the piping from the pool.

The pumps are designed to accept the following PVC pipes by tting the pipe to either the

inside or a pipe socket to the outside of the union tail.

Inlet PVC Outlet PVC

40mm Pipe ID /

50mm Socket OD

40mm Pipe ID /

50mm Socket OD

The use of any pipe smaller than those specied above is not recommended. Suction

piping should be free from all air leaks and any humps and hollows which cause suction

difculties. The discharge piping from the pump outlet should be connected to the inlet

connection on the swimming pool lter (usually at the lter control valve).

Barrel unions need to be hand tightened. No sealant, glues or silicones

are required.

Starting the Pump

To operate efciently and prevent pump damage there must be a free ow of water to and

from the pump. Before starting ensure that:

• All pipework is correctly sealed.

• The pool water level is at the correct height.

• Ensure that all appropriate valves are open and there is nothing preventing the ow of

water through the system.

1. When the pump is above the pool water line, rst prime the pump by removing the

strainer basket lid and lling the strainer basket area with water. Replace the lid,

ensuring that it seals on the O-ring.

2. Connect to the power supply and turn on.

3. Allow the pump to run, so that any air trapped may be expelled.

4. If prime is not established within approximately two minutes, as evidenced by a strong

ow of water, turn off the pump and repeat the procedure. Continued evidence of air

under the strainer basket lid indicates an air leak in the suction piping which should be

rectied to avoid pump damage.

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 on page 6.

Never run pump dry. Running the pump with no water may damage the

mechanical seals, causing leakage and ooding. Dry running damage

and associated damage is not covered under warranty. Davey SureFlo

pool pumps incorporate self-resetting thermal overload, reducing

potential damage.

Emptying the Strainer Basket

The strainer basket should be inspected frequently through the transparent lid and emptied

when a buildup of rubbish is evident. The directions below should be followed.

1. Turn off pump.

2. Close all valves in pipework.

3. Unscrew the strainer basket lid anti-clockwise and remove.

4. Remove the strainer basket by lifting upwards from its housing.

5. Empty the trapped refuse from the basket. Hose out with water if necessary.

6. Check the strainer basket for cracks, replace the strainer basket in the pump if OK.

Failure to undertake regular maintenance may cause damage not covered by warranty.

7. Replace the lid and ensure that it seals on the rubber O-ring. Firm hand tightness only is

required. The O-ring & thread can be lubricated with Hydra slip or equivalent products.

8. Open all valves in pipework.

Failure to undertake regular maintenance may cause damage not covered

by warranty.

Trouble Shooting

If the pump runs but there is no water ow or water ow is reduced, the following

condition may apply:

1. The lter 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 instruction 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 owing 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 prevent operating. 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 level is halfway 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. For 240 volt only, 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 following an overheating period. The pump 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 difculties with your Davey SureFlo

pool pump, contact the supplier from whom the pump was purchased or you’re 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. Turn off the power and remove the plug from the power source.

NOTE: If the pump is wired into a time clock or another automatic

control, the wiring should be removed by a qualied electrician.

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 O-rings.

4. Move the pipework with the barrel unions attached until the pump can be pulled clear.

NOTE: When making any enquiries about your Davey SureFlo pool pump be

certain to quote the model number from the nameplate located on motor.

Water Quality

Maintaining balanced water chemistry is important to the life of your pool pump. This pump is

designed to be used with Pool 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 3.0 PPM.

Please consult your local pool shop regularly to have your water tested.

POWER CONNECTIONS AND WIRING MUST BE CARRIED OUT BY

AN AUTHORISED ELECTRICIAN.

WARNING! Pump suction is hazardous and can trap and drown or

disembowel bathers. Do not block suction. Do not use or operate

swimming pools if a suction cover is broken, missing or loose. Two

suction covers and inlets must be provided into every pump to avoid

suction entrapment.

Caution! Do not add chemicals directly to the pool skimmer. Adding

undiluted chemicals may damage pump and lter and void warranty.

Small children using the pool 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 rst.

a. Make sure that any pressure gauges are in working condition and the

operating pressure is within limits as specied 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 qualied electrician as soon as damage is discovered.

h. Check water balance and sanitiser levels at your local pool shop.

i. Check for sufcient air-ow behind pump – clearance.

DANGER – Hazardous suction. Do not block water entry into ltration

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.
