Resetting the Safety Valve ... ONLY TO BE CARRIED OUT BY QUALIFIED SERVICE TECHNICIAN
The safety valve prevents damage to the pump seals and
valves caused by a pressure spike.
The safety valve should only be reset after checks to
ensure the unloader valve is working correctly. If in doubt
contact, your nearest Aussie Eco-clean service centre.
The following steps should be taken to reset the safety
valve, with the unit running.
1.
Unscrew the lock nut (C) on the safety valve and the
adjusting the hex knob (D), it should be screwed in
all the way.
2.
Loosen the lock nut (B) on the unloader and wind
the unloader knob (A) in gradually until the required
pressure is obtained whilst the trigger is pulled and
water is running through the pump. Do not exceed
the maximum rated pressure of the pump.
3.
The lock nut (B) should then be wound up to meet
the adjusting nut. The small grub screw in the
locking ring should be screwed in to secure.
4.
Paint mark across the nut and knob to identify any
tampering with the setting.
