Positioning and piping connection of the heater
To enable the power supply cable to be inserted through the back panel, allow space
behind the heater equal to at least the depth of the heater casing.
The minimum clearance above the heater should be 400mm.
The default water flow direction through the heater is left to right, allowing the
temperature controller to sense the temperature coming from the pool. This direction
can, however, be modified by following the instructions below.
The heater must never be installed at the highest point of a pipework system. Water may
drain from the heater causing damage to it. The pipework must be designed such that the
heater is always full of water.
The heater must always be installed horizontally and properly levelled; NEVER install
vertically.
Pipe connections are stub flanges to suit 120 mm (3") nominal bore pipe (uPVC or ABS). lf
using ABS the solvent jointing compound must be suitable for both materials. Reducers
may be fitted to suit smaller pipes.
It is not necessary to fit unions either side of the heater as the stub flanges are easily
disconnected from the heater, by removing the nuts securing the aluminium backing
flanges to the heater. In very tight installations, the studs themselves may be unscrewed.
