3.7 Fit a union nut onto each pipe.
3.8 Push the gasket over the pipe until the gasket is about 5 -10mm from the edge of the
pipe. You may need to lubricate the gasket.
3.9 Insert the pipe into the heat pump and tighten the union nut.
3.10 The union must only be hand tightened.
3.11 If the swimming pool is equipped with a chlorinator, brominator, or possibly chemical
control with acid and chlorine pumps, these must be in the return pipe work after the
heat pump and a non-return valve used. Any dosing system must be the final equipment
before the water returns to the swimming pool. Damage caused to the heat pump by
chemical dosing units is not covered by warranty.
3.12 Any heat exchanger or electric heater fitted as auxiliary heating must be installed
after (downstream from) the heat pump so as to avoid pre-heating the pool water before
it enters the heat pump.
