Start-Up

6.1 Hot-Water System

ATTENTION!
Only operate hot-water heat pump when filled with water!
Hot-water system requirements
The following materials may be found in the consumer's hot-
water system:
 Copper
 Stainless steel
 Brass
 Plastic
Depending on the materials used in the hot-water system (cus-
tomer installation), material incompatibility may lead to corrosion
damage. This especially applies to zinc-plated and aluminous
materials. If there is a risk of water contamination during opera-
tion, the installation of a filter may be required.
Hot-water system start-up
 All installations at the water circuit, air circuit, as well as all
electrical installations must have been performed correctly
and fully completed
 Filling hot-water system via external connection.
 De-aerate hot water system (open hot-water taps at the
highest extraction points until there are no more traces of
air).
Check entire hot-water system for leaks.

 Supply voltage.
 Switch on "Heat Pump" switch (see illustration).
 The desired hot-water temperature is infinitely adjustable
(up to 60 °C) via the temperature control button. A certain
heat-up time should always be allowed for, until the desired
temperature level has been reached (Hot water tempera-
tures above 45 C can extend the heating-up period consid-
erably).

Operation
Control panel
 Temperature indicator
The thermometer sensor measures the hot-water tempera-
ture in the upper part of the hot-water cylinder. The indicator
is located on the control panel.
1 Heat pump - " ventilation switch"

Switch position "O" Heat pump operation "OFF,
ventilation operation "OFF",

Switch position „ " Heat pump operation "ON",

in switch position „I" Heat pump operation "ON", ventilation operation "ON"
2 "Heating Element" switch
When the switch is in "I" position, the heating element is permanently switched
on.
The heating element is permanently switched off if the switch is in the
"O" position.

4 Temperature indicator
Hot-water temperature controller (rotary controller)
The rotary button is used to set the desired hot-water tempera-
ture. If the cylinder temperature is lower than the set hot-water
temperature, the heat pump is switched on (as long as the heat
pump switch is not in the "heat pump operation OFF" position).
The maximum hot-water temperature that can be attained with
the heat pump is 60 °C ±1.5 K. The standard heating element
can be used if higher temperatures are required.
