System installation

Installations of water should be carried out in accordance with the present
standards concerning installation of water. In accordance with the present


rules the coldwater connection should be provided with a drain valve, a
safety valve and an adjustable retaining valve. The valves are not standard
equipment.
Safety valve, check valve, drain
The heat pump installation must be equipped with a double check valve
and safety valve on the cold water supply line. This is to ensure that hot
water from the tank is not leaking into the cold water system and to release
pressure when the tank is heated. From the evaporator in the heat pump
there will be condensation water. The amount is depending on air humidity.
The safety valve and the condensation connection should be connected to a
drain to avoid leakage. For the specification of pipe connections - please see
the dimensional sketch "Technical data".
To maintain your cylinder for safety there is a requirement to check the
pressure relief valve 2-3 times yearly. To do this, the valve needs to be
turned clock wise half a turn until the valve clicks and closes. It is normal for
water to be released when this action is carried out" If water continues to
release after this test has been carried out the valve is faulty and requires
replacement.
To avoid injuries (scalding) from high water temperatures it is recommended
to install a thermostatic mixing valve on the hot water outlet. At normal
operation the temperature will not reach levels where scalding is a risk. If a
failure occurs during normal heating temperatures up to 70 °C is possible
before the safety thermostat will stop the immersion heater, otherwise the
immersion heater cuts out at 80 °C. If the safety thermostat cuts, it has to be
reset manually.
In order to avoid noise in the piping system it is recommended to use
approved couplings when connecting the heat pump. The heat pump can be
installed both stand alone and as a part of an existing system. When the tank
is filled during the startup it is necessary to bleed in order to get it filled.
The time needed to raise the water temperature from 10 °C to 45-55 °C is
between 8 and 10 hours at an ambient temperature of 15 °C.
