ROTECTION
The heater should be installed within a dry weatherproof enclosure.
CAUTION
If the heater is not used during winter months it must be drained to prevent frost damage.
Upon completion of the installation, run the water-circulating pump to purge the system & heater
of air (i.e. remove any trapped air in the system & heater).
The heater must be installed in accordance with the country / regional requirements &
regulations. In any event the work must be carried out by a qualified electrician, who will
provide a certificate of conformity upon completion of the work.
The power supply
must
be fitted with a RCD. If required your electrician may replace the
supplied cable entry gland with a larger one to secure the cable powering the heater, this will not
affect your warranty if carried out by a qualified electrician.
Cable section: 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).
