ixi gas pool and spa heater
Installation Manual
Section 6. Water Connections
Install pool system components with connections as
illustrated in
Figure 6
. Any configuration other than as
illustrated in
Figure 6
can affect the operation of the
water pressure switch. Locating the heater above or
below the pool water surface can also affect operation
of the water pressure switch.
NOTE:
When pool equipment is located below the pool
surface, AstralPool is not responsible for any large scale
water loss, fl ooding or damage caused by a leak.
CAUTION
The pool equipment must be protected from back-
siphoning of water. If there is any chance of back-
siphoning, provide a check valve between the pool and
the fi lter pump inlet.
6.1
Pump Sizing
The flow bypass within the heater manifold will
accommodate flows rates delivered to the heater from
a minimum of 114 Litres per minute (lpm) (30 gpm) to
a maximum flow of 379 lpm (100 gpm.)
CAUTION
The system water pump must be capable of providing
no less than 114 lpm (30 gpm) of fl ow through the
heater. Flow rates at less than 114 lpm (30 gpm) may
cause nuisance operation causing the heater to turn off
or damage to the heater.
