10. 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 water level is at the correct height.
• Ensure that all appropriate valves are open and there
is nothing preventing the flow of water through the
system.
1. When the pump is above the pool water line, first prime
the pump by removing the strainer basket lid and filling
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 flow 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
rectified to avoid pump damage.
11. 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.
12. 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 and unplug.
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.
9. Turn pump back on.
Failure to undertake regular
maintenance may cause damage
not covered by warranty.
13. 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 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. Ensure pump is
turned off. 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
difficulties with your Henden Single Speed pool pump,
contact the supplier from whom the pump was purchased
or your local Reece Irrigation & Pool branch as indicated
at the back of this manual.
The repair, removal and maintenance of the appliance
shall be carried out by the manufacturer or the
professional personnel of the agent.
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. Henden Single Speed
pool pumps incorporate self-resetting
thermal overload, reducing potential
damage.
