An automatic internal thermal overload switch protects the
motor from heat damage during operation and if operated can
restart without notice.
Maximum ambient temperature for motor operation must
not exceed maximum ambient temperature range (See page
4). Switch the pump off at the controller or power point while
ambient temperature exceeds maximum.

Priming Pump

Release all air from filter, pump and piping system:
refer filter owner's manual. In a flooded suction system
(water source higher than pump), pump will prime itself
when suction and discharge valves are opened.
If pump is not in a flooded suction system, disconnect power supply to pump follow
above instructions for removing trap lid; fill trap and pump with water.
Do not lubricate the trap lid o-ring. The original equipment O'ring contains a permanent
internal lubricant.
If the o-ring needs replacement insist on genuine Maytronics service parts. Clean and
inspect o-ring; reinstall on trap. Replace trap lid turn clockwise to tighten by hand only -
no wrenches!
Pump should prime now. Priming time will depend on vertical height of suction lift
and horizontal length of suction piping. The self-priming time range is 1 to 3 minutes
for a height difference of 2 to 3 metres, under normal installation conditions. Normal
conditions are understood to be: with suction having an internal diameter of DN 50mm,
water temperature at 20°C, and 50Hz mains power supply.
Should the pump not prime, ensure that all valves are open, lint trap is clear of debris
and suctions and suction pipe end is submersed in water, and that there are no leaks in
suction pipe. See troubleshooting guide.
