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 and 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.
It is essential that the power supply to the heater is protected by a
30mA RCD (Residual Current Device). If in doubt consult a qualified
Electrician.

Power Requirements

Flow Requirements

The flow rate of water into the heater must not exceed 17,000 litres per
hour (3,740 UK gallons/hour) A higher flow rate will require the installation
of a bypass to prevent damage to the heater element. The heater will not
operate with a flow rate below 1,000 litres / hour (220 UK gallons/hour)
