2. GENERAL INSTALLATION INSTRUCTION
2.1 Mounting instruction
The heater should be either installed horizontally or vertically allowing enough space for the pipe
connections and wiring. It should be firmly secured using screws to a firm base or wall.
WARNINGS: If the heater is placed against a combustible material a fireproof barrier must be
placed between the unit and the wall, this must cover a minimum of 15cm
around the outside of the heater. The unit must not be covered to allow adequate
ventilation.
The heater must be installed within a dry, permanent weather-proof area. In any
case where water or moisture enters the enclosure the warranty will be void.
Caution: If the heater is unused during the winter months, it must be drained to prevent
frost damage. Water must not be allowed to freeze in the heater, as this will
cause severe damage.
2.2 Pipework
The heater should be installed at a low point in the filtration system. It should be positioned downstream
of (after) the filter and upstream of (before) any dosing or other water treatment plan. (see Fig. 2).
