(inverter type) is used. The Lochinvar Limited states that it is of fundamental importance the correct flow rate of water source in order to avoid problems of freezing of the source heat exchanger. In this regard it is noted that the source water pump should be exclusively dedicated to the heat pump and, must be working as an on/off type control. -
Page 25: Chemical Characteristics Of The Water
System return water must be fitted to the connection labelled: ”USER WATER IN” as incorrect connection can damage the heat exchanger by freezing. It is compulsory to install on the USER WATER IN connection, a water strainer with a mesh not larger than 1 mm. Fitting this filter is COMPULSORY and the warranty will be invalidated if it is removed. -
Page 26: Installation With Source Open Circuit (Water To Water Heat Pump)
The limit values in the table may cause clogging by mud in the pipes and the heat exchanger. The maintenance of the quality of ground water is borne by the user and / or maintenance Lochinvar Limited. The temperature of source groundwater at the inlet of the source heat exchanger in heating mode, must not fall below 7.8 ° C to avoid freezing problems in the source circuit. -
