1.5 Installation of check-valve
Warning: When using automatic chlorine and pH dosing systems, it is of utmost importance to
protect the heat pump from high concentrations of chemicals as they could corrode the heat
exchanger. It is therefore recommended that these systems should add the chemicals into the
pipes located DOWNSTREAM (after) of the heat pump, and it is also recommended that a
check-valve be installed in order to prevent backflow when there is no water in circulation.
Damage to the heat pump caused by disregarding any of these recommendations will
invalidate the warranty.
