Pump Operation
Fill the bath to the correct level.
Air Switch Models
Depress the air button to operate the pump. Depress the air button again to switch
off the pump.
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.
Electronic Models
“Spa” button
- turns pump and heater on/off together.
“Boost Heat” button - enables the heater to be turned off/on while pump is running.
CAUTION
To operate efficiently and prevent pump damage there must be a free flow of water to and
from the pump. Ensure that any valves are appropriately positioned and there is nothing
else preventing the flow of water through the system.
If the pump stops due to power failure or overheating, turn the pump off otherwise it will
automatically restart when power supply resumes or the motor cools down.
Avoid filling the bath with very hot water as this may cause “nuisance tripping” of the
element in heated models (refer TROUBLE SHOOTING section part C). Nuisance tripping
can be prevented by partially filling the bath with cold water and then adding hot water for
a comfortable temperature.
Avoid foreign objects such as tissues or large amounts of hair entering the bath water as
they may be drawn into the pump causing it to jam.
Trouble Shooting
A) If the pump runs, but does not deliver water, the following may be the cause:
1. The pump is mounted too high relative to the jets in the bath, causing it to air lock.
Usually this can be rectified by activating the air bleed
(refer to section ACTIVATING AIR BLEED)
If this fails, the pump will have to be lowered 10 - 15 mm at a time until it primes
(refer to section PLUMBING INSTALLATION).
2. Leak in the suction pipework allowing air to be drawn in.
3. Pipework is blocked.
B) If the motor does not run, the following may be the cause:
1. Power is not connected or a fuse has blown.
2. Overload has been tripped.
The motor is fitted with an automatic re-set overload which is designed to protect
the motor from damage under overload conditions. Allow the motor to cool and
the overload will re-set automatically to start the pump again. Determine the cause
of overload if possible and rectify. Constant stopping indicates a problem to be
rectified before permanent damage occurs.
3. Air operated switch is in “OFF” condition.
