Safety group
When water is heated to 60 °C, it expands by 2%. A pressured tank could burst without a safety valve keeping excess water out. The
safety valve should therefore drip during warming up.
The end of the overflow pipe must be visible, and it must be able to run out safely via the drain.
Safety group with anti-scald protection
In the control, a temperature limit for the domestic hot water of 65ºC is set as standard. This setting prevents scalding of the users
when the hot water tap is opened.
When the unit is in cooling mode, the energy is deposited in the hot domestic water tank instead of leading it out of the house. This also
means that if the hot water temperature exceeds 65ºC, the unit stops cooling the supply air. If there is a larger need for cooling, the
temperature limit can be raised to 80ºC, but then a scalding fuse must be fitted under the hot water tank, which prevents users from
scalding when they open the hot water tap.
The scald protection mixes the hot water with cold water so that the temperature is lowered and scalding is avoided. This extended the
period during which Compact can cool.
CAUTION
Safety group must be installed in connection with hot water tanks.
Installation:
a. The double nut is attached to the water heater´s cold water pipe so that the arrows are point-
ing in towards the water heater (in the direction of the flow). The joint with the water heater is
sealed using a threaded washer.
b. The joint between the double nut and the unit is sealed using fibre packing.
c. The rubber ring seal (the O-ring) is fitted to the unit so that it can function as a seal between the
safety valve and the unit in such a way that the valve is locked.
ATTENTION
Water expands as it heats up, therefore the safety valve will drip.
ATTENTION
The installer is responsibly to instruct the consumer about the location and function of the safety valve, as well as that
the safety group at least twice a year should be tested to avoid overgrowth.
CAUTION
If a solar panel is connected to the hot water tank, an anti-scald device must be mounted.
1. Hot water from the hot water tank
2. Cold water to the hot water tank
3. Stop tap cold water
4. Pressure relief valve
5. The overflows from the safety valve are led to a prominent drain
6. Cold water supply
7. Domestic hot water for the dwelling
8. Mixing valve for domestic hot water for the dwelling (can be set between 35 - 60 ºC)
