Water connection
The
inner tank surface is enamelled and the tank is equipped with a sacrificial anode.
All connectors have 3/4” threads, with the exception of the anode access which is a 5/4” sleeve.
All water pipes are connected to the bottom of the unit.
If
required, hot water circulation can be established by fitting a non-return valve to the recirculation
connector of the tank after inserting a 80cm long circulation pipe (optional accessory) into the tank.
See figure 3 below.
If
hot water circulation is not required, the connector and fitted blanking plug should be left un-
touched.
Hot
water circulation may result in considerable heat loss within the piping system. A large propor-
tion of heat pump output may therefore be lost. To prevent heat loss, circulation and hot water
pipes must be insulated with at least 30mm of mineral wool or other type of pipe insulating materi-
al.

Note: The water tank must be filled with water before the unit start up.
Supplementary heating element DHW
The hot water tank has a supplementary heating element of 1,5kW. The heating element can be
activated and de-activated via the CTS 602 control, see the “Hotwater” menu.
The temperature, at which the heating element should be active (T11), can be set in the “Hotwater”
menu, see “Directions for use of the CTS 602 control
