Description
2.1
General Information
The hot-water heat pump is a ready-to-use heating device and
mainly consists of hot water cylinders, the components for the refrigerant, air and water circuits, as well as all of the control, regulation and monitoring devices required for automatic operation.
Using electrical energy, the hot-water heat pump heats water
using the heat stored in the air which is sucked in. The hot-water
heat pump with internal heat exchanger can be connected to additional heat generators such as heat boilers or solar installations. A vertical cladding tube (inner ∅ ≥ 12 mm) houses an external temperature sensor. The devices are standard equipped
with an electric heating element (1.5 kW).
The temperature of the air sucked in (the heat source) is used as
reference value for energy consumption and DHW preparation
heat-up time.
For this reason, an air duct system (DN 160, max. length 10 m)
can be connected to the standard spigot of the hot-water heat
pump for specific waste heat recovery. In principle, effective operation of the heat pump requires that there is no air short-circuit
between the air that is sucked in and the air that is blown out.
This can, for example, be achieved by a flexible air hose on the
intake and outlet side.
Falling outlet air temperatures reduce heat pump performance
and increase heat-up time. Air inlet temperature should not fall
below 15 °C for economical heat pump operation. If the air inlet
temperature falls below 8 °C ±1.5 (dead-band value 3 K), the
heat pump is switched off and the DHW is heated by the standard heating element (1.5 kW).
The electric heating element fulfils four functions:
„ Supplementary heating
The heating-up period is approx. halved by switching on the
heating element (using the “Heating Element” switch, see
Point 2.3) in addition to the heat pump.
„ Frost protection
If the air temperature falls below 8 ±1,5 °C (dead-band value
3 K), the electric heating element switches on automatically
and (nominally) heats the water up to the set hot water temperature. The hot-water temperature generated by the heating element in antifreeze mode can exceed the set value!
„ Emergency heating
The water supply is maintained by the electric heating element if the heat pump is out of order.
„ Higher water temperature
If the required hot water temperature is higher than the temperature achievable by the heat pump (approx. 60 °C), it can
be raised to a max. of 85 °C by using the heating element.
ATTENTION!
When the hot water temperature reaches > 60 °C, the heat pump switches
off and the hot water is heated solely by the heating element. The heating
element controller is factory set to 65 °C (see 3.3.3).
2.2
Refrigerant Circuit (Heat Pump
Operating Principle)
The refrigerant circuit is a closed-loop system in which the refrigerant R134a is the energy source. The finned heat exchanger extracts heat from the air sucked in at a low evaporation temperature, and transfers it to the refrigerant. The vaporous refrigerant
is sucked in by a compressor where it is compressed to a higher
pressure and temperature level before being transported to the
liquifier, where the heat taken up in the evaporator and part of the
compressing energy is transferred to the water. Subsequently,
the high condensation pressure is lowered to the evaporation
pressure via a throttle mechanism (expansion valve). In the
evaporator, the refrigerant will again take up heat from the air
that is sucked in.
2.3
Water Circuit
The hot-water heat pump water circuits depend on the pump type
(with or without internal heat exchanger). They must be installed
on site. The water connections (see illustration) are at the rear of
the unit.

Safety and Control Devices
The hot-water heat pump has the following safety features:
High-pressure switch
The high-pressure switch protects the heat pump against impermissibly high operating pressure in the refrigerant circuit. In the
event of fault, the pressure switch will switch off the heat pump.
The heat pump is restarted automatically if there has been a
pressure drop in the refrigerant circuit.
Safety temperature limiter for heating element
(STL)
English
The STL protects the hot-water installation against impermissible
temperature increases.
The heating element is switched off if the set switching value
(99°C) is exceeded.
The heating element cannot be re-started until the hot-water temperature has decreased to ≤ 90 °C and the reset button (see illustration) on the STL is pressed (this may be done by qualified
personnel only).

&RQWUROSDQHO
The hot-water heat pump is equipped with the following regulation and control devices:
Heating element temperature controller (TC)
The heating element temperature controller regulates the hot
water temperature during heating element operation. The maximum controller temperature is factory set to 65 °C (the controller
and the STL are installed together in a casing). Temperature settings can be changed using suitable tools (see illustration).
Changes to this setting may be carried out by qualified personnel
only!
In automatic operation (activated via air temperature thermostat),
the water is heated by the heating element until the set value has
been reached (by the heat pump temperature controller). In contrast to heat pump operation only, a smaller amount of water is
heated up in order to minimise heating element operating periods. In continuous manual operation, the hot water is heated until
the set maximum temperature of the heating element has been
reached. The heating element may optionally be controlled via
an external switch (see Point “Electrical Connection”). The water
is again heated until the set maximum temperature of the heating
element controller has been reached.
E-4
Heat pump temperature controller
Temperature control in the water cylinder and the regulation for
compressor operation is carried out by the temperature controller. This controller measures the hot-water temperature via a
sensor and controls it in relation to the set value. The desired
temperature level (set value) is set via the rotary knob on the
control panel.
Air temperature thermostat
This thermostat sensor measures the hot-water heat pump temperature directly upstream of the evaporator (air inlet temperature). If the temperature falls below the set value (8 ±1,5 °C,
dead-band value 3 K), hot water preparation automatically
switches from heat pump operation to heat element operation.

3.1
Storage and Transport
General Information
The hot-water heat pump should generally be stored and transported wrapped up, upright and containing no water. If handled
carefully, the unit can be transported over short distances with a
max. tilt angle of 45°. Ambient temperatures between -20 and
+60 °C are permissible during transport and storage.
3.2
Fork-Lift Truck (or Lift Truck)
Transport
The hot-water heat pump must remain installed on the pallet during fork-lift transport. The pump should be lifted slowly. Because
of its high centre of mass, the hot-water heat pump must be secured against canting. To prevent damage, the hot-water heat
pump must be lowered onto a level surface.
3.3
Manual Transport
Use the wooden pallet for manual transport. A second or third
carrying position can be determined with the help of ropes or carrying slings (these may be positioned around the ventilator case
and fixed to the water pipe nipples). If the pump is transported in
this manner (or with a sack barrow), the max. tilt angle of 45°
must not be exceeded (see illustration). If the pump can only be
transported in a tilted position, the hot-water heat pump ("heat
pump" switch) should not be operated until at least one hour after
installation in its final location.

Minimum room height for “free venting” is approx. 2.5 m
Installation Location
4.2
Installation location criteria:
„ The hot-water heat pump must be installed in a frost-free
and dry room. The room temperature / air sucked in by the
hot-water heat pump should be within a temperature range
of 15 °C to 35 °C (required for heat pump operation).
„ Furthermore, installation and air intake is not permitted in
rooms with air which is potentially explosive because of
gases, vapours or dust.
„ In order to prevent damage to interior walls caused by
dampness, it is recommended to provide good thermal insulation between the room into which the exhaust air is released and the neighbouring rooms.
„ Condensate drainage (with a siphon) must be provided.
„ The air sucked in must not be excessively contaminated or
contain large amounts of dust.
„ The load-bearing capacity of the foundation must be sufficient (weight of the filled hot-water heat pump approx.
410 kg!).
To ensure smooth operation and facilitate repair and maintenance work there should be a minimum clearance of 0.6 m on all
sides of the device, as well as a minimum room height of approx.
2.50 m for operation without air ducts/hoses or bends (Î "free
venting") when the hot-water heat pump is installed (see illustration). Hot-water heat pump connection is (optionally) performed
with insulated ductwork of the NW 160, which must not exceed a
total length of 10 m.
To ensure effective operation, an air circuit bend (90° NW 160)
must be installed on the blow-out side in rooms with lower ceilings and without ductwork. If the air circuit bend is used, place it
onto the spigot (nominal width DN 160) of the outlet side so that
the exhaust air outlet of the air circuit bend is as far away from
the unit's intake opening as possible. Also observe the minimum
clearances as shown in the illustration. The hot-water heat pump
air connection stubs ("intake stub" and "outlet stub") are labelled
with stickers.

Set-Up
„ Remove the three M12 transport restraint screws fixing the
unit to the pallet.
„ Remove pallet and install the three M12 supporting feet (in
plastic bag attached to the cylinder barrel nipple).
„ Position the hot-water heat pump and align vertically by adjusting the device feet! Then tighten the counternuts on the
device feet.

Installation
5.1
Connecting the Water Pipes
The nominal pipe widths for the on-site sanitary installation must
be determined by taking into account the available water pressure and any pressure drops expected to occur in the pipework.
Water installations must be executed according to DIN 1988 (see
Appendix – for example, a pressure reducing valve must be used
if water pipe pressure is impermissibly high); also observe local
regulations for domestic water installations!
Both rigid and flexible water pipes are possible. Observe corrosion behaviour of the pipework materials to prevent damage
caused by corrosion (see Section: Start-Up).
ATTENTION!
When installing the on-site pipework, ensure the pipes do not get
contaminated (flush pipes before connecting hot-water heat pump)!

Connecting the Condensed
Water Pipe
The condensed water hose is fed through the foil cladding at the
rear of the device. It should be routed so that the condensate
produced (during heat pump operation) can flow away freely.
English
There is a pressureless seal valve which must also be relocated
when shortening the condensed water hose (valve can be easily
removed and replaced into the hose). This valve is of special importance if longer air hoses are fitted to the device or if a filter is
installed on the exhaust air side. The condensate should be
drained into a siphon (see maintenance information 7.1).

5.3
6.1
Electrical Connection
The hot-water heat pump is wired ready for use; power is supplied via connection cables plugged into an earthed wall socket
(~230 V, 50 Hz). This socket has to remain accessible after installation.
To control external devices for the second heat generator (hotwater heat pumps with internal heat exchanger only), a separate
cable has to be connected to the device via an available cable
union and be strain relieved. (For this electrical connection, the
hot-water heat pump plastic cover has to be removed.) The cable
must then be led through the available cable feedthrough provided, and guided through the partition. The electrical connection
terminal (X5 – 4/5/PE) with a floating contact to control (ON/OFF)
the external ancillary devices (pump, solenoid valve etc.) is located on the rear of the partition in the device.
External heating element control
It is possible to optionally control the heating element via an external switch (e.g. timer), in parallel to the “Heating Element”
switch on the hot-water heat pump operator panel. For this connection, a floating contact on the external switchgear is required.
2
Furthermore, an additional cable (min. 2 x 1.0 mm / max. cable
outside diameter 10 mm) must be inserted into the device and attached to connection 6 and 7 of terminal strip X5.

Hot-water system requirements
The following materials may be found in the consumer's hotwater system:
„ Copper
„ Stainless steel
„ Brass
„ Plastic
Depending on the materials used in the hot-water system (customer 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 operation, 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.

„ The desired hot-water temperature is infinitely adjustable
(up to 60 °C) via the temperature control button (see illustration). A certain heat-up time should always be allowed for,
until the desired temperature level has been reached.
6.2
Hot-Water Heat Pump
Operation
Hot-water temperature controller (rotary controller)
The rotary button is used to set the desired hot-water temperature. If the cylinder temperature is lower than the set hot-water
temperature, the heat pump is switched on (if the heat pump
switch is in the “Heat Pump Operation ON” position).
Control panel
„ Temperature indicator
The thermometer sensor (analogue distance thermometer)
measures the hot-water temperature in the upper part of the
hot-water cylinder. The indicator is located on the control
panel.
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.
Notes on economical use of energy:
„ To achieve a high COP with the integrated heat pump while
cutting water level losses, the hot-water heat pump should
normally not be operated at a hot-water temperature of more
than 45 °C (see illustration).
„ Only set the temperature controller to higher values or manually switch on the heating element if necessary.
„ To ensure optimum compressor operating times and downtimes, it is important to avoid manual and repeated switching
on and off of the heat pump!

If more hot water is needed or if a higher water temperature
(> 60 ±2 °C) is desired, the "Heating Element" switch can be
used to switch on the integrated 1.5 kW radiator.
If the "Heating Element" switch is in the "I" position, the approx.
upper third of the cylinder will be heated up to the maximum temperature of the heating element controller (factory setting 65 °C);
at hot-water temperatures > 60 °C, DHW preparation is done by
heating element only. It is possible to optionally control the heating element via an external switch (see point 5.3). If the "Heating
Element" switch is in the " " position (automatic operation) and
the air temperature is 8 ±1.5 °C (dead-band value 3 K), the cylinder volume is heated up (nominally only) to the setpoint temperature of the hot-water temperature controller.
Note → Heating element controller
The heating element controller is a second control unit for the operating range of the electric heating element, and independent of
the hot-water controller. The factory set switch-off temperature of
65 °C can be changed by a technician (see Point 2.4)
"Heat Exchanger" switch (hot-water heat pumps

Heat pump operation can be blocked as required if domestic hot
water is to be prepared using a second heat generator. This is
achieved by removing the factory-mounted copper bridge A2 (at
terminal strip X5, see Section 5.3) and integrating a floating contact from the second heat generator regulation in the same position. An external regulation must not lead to the maximum
switching frequency (12 operations/h) of the heat pump being exceeded. It may be necessary to take the local utility company
(EVU) specifications into consideration in this regard.
7.1
Relay for heat exchanger operation
Relay with a floating contact (hot-water heat pumps with internal
heat exchanger only) to control the ancillary devices (pump, solenoid valve etc.) for operation with a second heat generator. The
relay contact is closed when the "Heat Exchanger" switch is activated and a hot water request from the hot-water heat pump temperature controller is present.
7.2
Sensor pipe for external temperature sensors
A vertical sensor pipe ∅i 12mm (opening in the bottom plate
sealed with a leading-in tube) for an external heat sensor is fitted
in the rear of the hot-water heat pump and a cable feedthrough is
available in the rear panel.
Water Circuit / Condensate
Outflow
The water circuit check is limited to filters that may have been installed on-site, and possible leakage. Dirty water filters should be
cleaned and replaced if necessary. Occasionally check the seal
valve in the condensed water hose for contamination; replace if
necessary.
Air Circuit
Maintenance work is limited to cleaning the evaporator 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 contamination and cleaned and replaced if necessary.
7.3
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 ammeter, without
draining the tank.
Procedure:
External temperature sensor installation position
(device cover removed)

Maintenance
ATTENTION!
Disconnect the power supply before opening the hot-water heat pump;
observe possible coasting of ventilator.
General information
The hot water heat pump is virtually maintenance-free. 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.
Do not carry out any maintenance work on the refrigerating circuit of the heat pump.
Only use a damp cloth and soap solution for cleaning the hotwater heat pump.
ATTENTION!
Ensure water does not come into contact with the operator controls.
Unplug mains plug/disconnect the power supply before beginning any
cleaning work.
E-8
1)
Unplug PE cable from protection anode tab.
2)
Connect ammeter (0...50mA) 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 inspection of the protection anode by a technician is recommended.
Should replacement of the protection anode [by a technician] be
necessary, 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!
