OSITIONING
Your heater must be screw fixed to a firm base or wall. The heater
MUST
be horizontal and
upright i.e. with the control enclosure located above the flow tube (see diagram below). Under no
circumstances should the heater be operated in any other orientation.
The heater should be installed at a low point in the filtration system. It should be positioned after
(i.e. downstream) of the filter but before (i.e. upstream) of any dosing or other water treatment
plant.
NOTE If the
flow direction
is reversed
(explained
later in this
booklet) the
heater
MUST
remain sited
after the filter.
Only clean filtered water
should enter the heater.
It is essential that the pipe work connecting to and from the heater has a minimum bore (internal
diameter) of 1¼’’ (32-mm).
To assist correct air purging and to ensure the heater remains completely full of water during
operation, the return pipe which carries the water back to the pool must incorporate a safety loop
or kick up in the pipe, installed as close as possible to the heater (see diagram on following
page).
Note: When coupling to flexible pipe a safety loop can simply be created by routing the pipe up
and over an obstacle. Remember to use pipe clips to securely fasten all hose connections.
