Pipe Work
It is essential that the pipe work connecting to and from the heater
has a minimum bore (internal diameter) of 1¼” (32mm). 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 as close as possible to the
heater (see fi g 4)
NOTE: When coupling to a fl exible 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.
Weather Protection
The heater must be installed within a dry weather proof enclosure.
Caution! If the heater is not used during winter months it must be drained to
prevent frost damage.
Electrical Connection
The heater must be installed in accordance with the country / regional
requirements & regulations. In any event the work must be carried out by
a qualifi ed electrician, who will provide a certifi cate of conformity upon
completion of the work. The power supply must be fi tted with a RCD. If
required your electrician may replace the supplied cable entry gland with a
larger size to secure the cable powering the heater, this will not aff ect your
warranty if carried out by a qualifi ed electrician.
Cable section: This should be calculated at 5-amp / mm2 for distances
up to 20 metres (these sections are indicative and should be checked and
adapted if necessary for cable lengths over 20 metres.
