Note: If automatic dosing equipment for chlorine and acidity (pH) is used, it is essential to protect the
heat pump against excessively high chemical concentrations which may corrode the heat exchanger.
For this reason, equipment of this sort must always be fitted in the piping on the downstream side of
the heat pump, and it is rSMARTmmended to install a check-valve to prevent reverse flow in the
absence of water circulation.
Damage to the heat pump caused by failure to observe this instruction is not covered by the warranty.
