12. TROUBLE SHOOTING
If the pump runs but there is no water flow or
water flow is reduced, the following condition
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 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 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 prevent 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 level is up to the skimmer box. Typically half
way up the face of the skimmer box is sufficient.
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 220-240 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. The pump has an in-built
thermal overload which will reset automatically after
the motor has cooled following an overheating period.
Determine the cause of the overload tripping and
rectify. Reset the pump by switching the power OFF for
30 seconds.
3. Blockage is preventing the pump from rotating.
13. 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 o-rings.
4. Move the pipework with the barrel unions attached
until the pump can be pulled clear.
14. 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 7.6 and is regularly treated with a chlorine sanitising
agent with the level not regularly exceeding 3.0 ppm.
Please consult your local Reece Irrigation & Pools branch
regularly to have your water tested.
NOTE When making any enquiries about
your Henden Variable Speed Pump be
certain to quote the model number from
the nameplate located on the motor.
NOTE: If the pump is hard-wired into
a time clock or another automatic
control, the wiring should be removed
by a qualified technician.
