7 Start-Up
7.1 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
„ Filling hot water system via external connection.
„ De-aerate
hot water system (open hot-water taps at the highest extrac-
tion points until there are no more traces of air).
„ Check entire hot water system for leaks .
„ Supply voltage (plug in socket).
„ Switch on heat pump switch (see illustration in 3.1).
„ The desired hot water temperature is infinitely adjustable
(up to 60 °C) via the temperature control button.
„ If hot water consumption is high, the electric heating ele-
ment is switched on automatically or manually at air inlet
temperatures of below 8 °C.
„ Hot water preparation via a second heat generator is pos-
sible by switching on the heat exchanger loading pump (pro-
vided that the required electrical connection has been estab-
lished).
8 Maintenance
ATTENTION!
Before opening the hot-water heat pump, unplug mains plug and observe
possible coasting of ventilator!
General Information
Do not carry out any maintenance work on the refrigerating cir-
cuit of the heat pump. Only use a damp cloth and soap solution
for cleaning the hot-water heat pump.
ATTENTION!
Ensure water does not come into contact with the operator controls.
Furthermore, a one-off visual inspection for possible leakage in
the water system or stopping-up of the condensate outflow
should take place a few days after the maintenance work has
been carried out.
8.1 Water Circuit / Condensate
Outflow
The water circuit check is limited to filters that may have been in-
stalled on-site, and possible leakage. Dirty water filters should be
cleaned and replaced if necessary. The seal valve in the con-
densed water hose should occasionally be checked for contami-
nation, and replaced if necessary.
8.2 Air Cycle
Maintenance work is limited to cleaning the evaporator (with a
vacuum cleaner) on a regular basis, and as needed.
ATTENTION!
Risk of injury caused by sharp-edged fins. Fins must not be deformed or
damaged!
If air filters are used, they should be regularly checked for con-
tamination and cleaned and replaced if necessary.
8.3 Corrosion Protection Anode
The corrosion protection anode installed in the hot water cylinder
should be electrically checked on a regular basis, at least every
two years after start-up, and be replaced if necessary. Electrical
checking is carried out by means of a suitable electric current
meter, without draining the tank.
Procedure:
1) Unplug PE cable from protecting anode tab.
2) Connect ammeter (0 ... 50 mA) between PE cable and tab.
3) Evaluation of protection anode wear:
Measured value > 1 mA
⇒
protection anode is in working
order.
Measured value < 1 mA
⇒
protection anode must be tested
or
replaced.
If electrical testing does not provide any clear results, a visual in-
spection of the protection anode is recommended. Should re-
placement of the protection anode [by a technician] be neces-
sary, the tank must be drained via the valve provided (fitted
during installation - see appendix).
ATTENTION!
Malfunctioning protection anodes reduce the operating life of the device!
(Reactive anode: electrically insulated magnesium anode with selenium
according to DIN 4753 Part 6)
