Purge air from plumbing system
TIPS ON FILLING SPA
•
Before filling remove spa skirt and be sure that all valves in the plumbing
system are fully open to maximise the amount of air that can escape the pipe
work during filling
•
Remove filter cartridge(s) before filling and be sure to fill the spa through the
filter itself to flood the pipe work with water and minimise the chance of air
pockets forming in the plumbing during the filling process.
•
DO NOT fill spa by placing hose in the foot well. Filling a spa this way will create
a large number of air pockets in the pipe work and may cause difficulty when
priming. Always fill spa through the filter area.
•
Once the spa is filled to the correct level attempt to power up the spa with the
filter cartridges still removed. Verify that the spa controller completes its
priming sequence and begins normal operation. Once normal operation has
been verified turn mains power off, re-install filter cartridge(s) and restart spa.
WARNING
RESTRICTION OF WATER FLOW DUE TO DIRTY FILTER CARTRIDGES IS THE MOST
COMMON CAUSE OF ER-3 FAULTS.
IF THE SPA POOL HAS BEEN OPERATING
NORMALLY THEN INTERMITTENT ER-3 FAULTS START TO OCCUR THE FILTER
CARTRIDGE(S) WILL REQUIRE SERVICING.
DEPENDING ON TYPE OF FILTER CARTRIDGE(S) INSTALLED THE FILTERS WILL EITHER
REQUIRE CLEANING, SOAKING IN A FILTER CARTRIDGE DEGREASER SOLUTION OR
REPLACING. REFER TO SPA RESELLER / MANUFACTURER FOR DETAILS ON TYPE OF
CARTRIDGE INSTALLED AND RECOMMENDED CLEANING FREQUENCY & METHODS.
Every time the power is turned on the SV controller will initiate a water priming
sequence on start up. During a priming sequence the filtration pump will run for up to 20
seconds at a time in an attempt to purge air from the plumbing. The keypad display will
scroll PRIMING during this sequence.
If the spa controller is successful in clearing all of the air from the heater tube the system
will begin normal operation. However if air is still detected the spa controller will shut
down and latch on fault code (ER3-Water Prime).
How do I solve ER-3 WATER PRIME:
Press Pump A button to retry water priming sequence
Check spa is filled to correct operating level as advised by spa manufacturer
(refill if necessary)
Remove filter cartridge(s) and retry water prime
With mains power turned OFF, bleed airlock from pipe work by slightly
loosening couplings on front of filtration pump and allowing air to escape
With filter cartridge(s) removed use hose to flush water down pipe work in an
attempt to clear the air pockets from the plumbing
IMPORTANT NOTE
Do not allow the filtration pump to continue to run after five (5) x failed priming attempts.
Operating a pump without water for extended periods may cause damage to the pump.
Turns power off, wait ten (10) minutes and then try again later.
The in-heater water sensor constantly monitors the presence of water in the heater tube. If
at any time air bubbles are detected the spa controller will automatically cancel all current
operations and force a water priming sequence to begin. This will occur whether the spa is
in automatic mode or manual use. If the priming sequence is successful in clearing the air
pockets from the plumbing normal spa operation will resume in automatic mode. If
unsuccessful the spa controller will shut down and latch on fault code ER-3 Water Prime.
