4. Re pressurise the system to 2.0 bar as necessary
5. Open the top vent of the heat exchanger by rotating
the plastic section connected to the silicone tubing.
Close the vent when water is released.
6. Re pressurise the system to 2.0 bar as necessary
7. Operate the internal heater pump for about 10
seconds by holding in the button located underneath
the power switch on the front of the heater.
8. Vent using the top and side vents until water ap-
pears
9. Re pressurise to 1.5 bar as necessary
10. Repeat items 7 - 9 until no air can be heard when
the pump button is pressed.
11. Operate the pump for repeatedly for short periods (2
seconds on - 2 seconds off ) to shift any remaining
air to the vent points, and vent any remaining air.
12. Operate the pump for around 1 minute to confi rm
that all air has been vented. The pump should oper-
ate almost silently when all air has been vented.
13. Vent further times if necessary.
ONLY when you are satisfi ed that the noise
of air in the primary system is no longer
present, should commissioning proceed
with the gas supply turned ON and the pool
pump operating (see following page)
THIS HEATER AS SUPPLIED IS NOT FILLED
WITH SUFFICIENT WATER IN THE PRIMARY
CIRCUIT. DO NOT UNDER ANY CIRCUM-
STANCES OPERATE THIS HEATER UNTIL
THE PRIMARY CIRCUIT HAS BEEN FILLED
& PRESSURISED WITH WATER & ALL AIR
HAS BEEN VENTED.
IT IS ESSENTIAL TO FOLLOW THE GUID-
ANCE BELOW, AS PERMANENT DAMAGE
COULD OCCUR TO THE PRIMARY HEAT
EXCHANGER AND THIS DAMAGE WILL
NOT BE COVERED BY THE WARRANTEE
This heater primary circuit contains Sentinel
X500 inhibitor/anti-freeze. Minimum water
should be released during
fi lling and venting to
maintain its concentration.
4.1 REMOVAL OF PRIMARY SYSTEM AIR
The elimination of air from the heat exchanger is es-
sential to maximise the life of the heater. The following
venting procedure should be followed with the heater
powered, the gas supply turned off and the pool pump off :
1. Connect a pressurised fresh water supply to the
water fi ll point directly or use the hoselock attachment
supplied.
2. Referring to the pressure gauge on the front of the
heater, initially open the shut off valve and pressurise
the primary system to 2.9 bar.
3. Open the side vent on the right hand side of the
heater and vent until water is released
