Safety instructions
1. Read and strictly follow the installation and operating instructions to ensure a long
life and reliable operation of this appliance.
2. Installation and use of heat pump inconsistent with this instruction is not permitted
- may cause malfunction and will void the warranty.
3. Room for installation should have cubature of minimum 20 m3and provide adequate
air exchange.
4. Device must not be installed in rooms where the ambient temperature may drop
below 0°C.
5. Mounting and commissioning of heat pump and accompanying installation should
be entrusted to a specialist service company.
6. Heat pump should be installed only in horizontal position on a at surface with
appropriate lifting capacity.
7. Device must be installed in such a place and in a such a way that the emergency
leakage from connectors would not cause ooding of the room.
8. Room must have a possibility to drain condensate to the sewer.
9. After installation device must be connected to water supply system and optionally
to heating system as described in the manual. Inconsistence with the description
of the connection invalidates the warranty and may cause malfunction.
10. Connection to the water supply system must be made in accordance with the binding
norms.
11. Heat pump is designed to connect to installation with pressure not exceeding
0,6MPa. If the water pressure exceeds 0,6MPa, install a pressure reducing valve
in front of the machine.
12. Water dripping from the discharge pipe of the safety valve is normal and should not
be prevented because blocking the valve can be the cause of failure.
13. Do not use the device if there is a possibility that the valve security is broken.
14. The tank is equipped with a magnesium anode - an additional protection against
corrosion. The anode is an operating part, therefore, it is exposed to wear.
The condition of the magnesium anode should be controlled every 12 months,
however, it is due to be replaced with a new one every 18 months.
15. The heating medium temperature must not exceed 80°C !.

cold water inlet connection between and safety valve; at its outlet cannot be placed
any cut-off valve or any throttling element; safety valve must be installed so that
water leak is visible,
- connect heat pump with mounted safety valve to water supply system,
- install cut-off valve at cold water inlet. Domestic hot water outlet must be connected
to CW connector which is located at the upper part of device.
- each device is equipped with a C connector designed to connect circulation.
Connection to the heating and water supply system
Connection to the water supply system must be
done in accordance with the binding norms. Heating
pump HPSW 2 is a pressure device adapted for
connection to water supply system not exceeding
pressure 0,6MPa. If the water pressure exceeds 0,6
MPa, install a pressure reducing valve in front of the
machine.

the device. Siphon should be hermetically connected to the condensate pipe and then
led to sewerage. The pipe should be led without any bends to allow free drainage.
Device is equipped with a power cord that must be permanently connected to electrical
installation.
The electrical system should be equipped with a residual current protective devices and
means providing that device can be disconnected from power source where distance
between joints of all poles is not less than 3 mm.
Before starting the unit, visually check the connection of the device and proper installation
in accordance with the diagrams.
Cylinder must be lled with water:
- open the valve on the cold water inlet,
- open the valve on the hot water outlet installation (full ow of water stream, without
air bubbles indicates that the tank is full)
- close the taps.
Open the valves connecting the heating system with the coil. Check for leaks on the
sanitary hot water and heating medium side. Check the operation of the safety valve
(in accordance with the valve’s manufacturer instruction).

Note that connection of the sensor is optional. When it is not mounted,
circulation pump works continuously according to circulation schedule.
If the sensor is mounted, circulation pump also works according to circulation
schedule but only until the temperature in the circulation stabilizes.
At certain time intervals circulation temperature is veried. If water temperature
needs to be raised, the pump is activated.
When the sensor is not mounted, the pump works continuously. When the sensor is
mounted, the pump works when temperature in circulation declines. Control system
automatically detects the presence of the sensor and adjusts accordingly circulation
pump control algorithm.
Master appliance (entry NA)
In order to limit the electricity used, it is possible to make the work of devices conditional
from other external controllers. In this case, the break contact needs to be connected
to NA entry so that switching on electricity master appliance will result in opening the
contact, which will block the heating.
Function entry (entry FN)
Entry of switching on heating regardless of the schedule. In order to use this function
the break contact needs to be connected to NA entry. Contraction of FN entry will result
in turning on heating with all available sources (heat pump, coil heater, external heat
source) to setting 60°C.
Exit ZC
It is a relay output for controlling an external heat source. It is active only if option
“Additional heat source” was switched on in setup.

Failures
If fault occurs there will be Err message on display. In case of error contact authorized
service of Kospel.
Anode’s state control
When device is in use, the anode wears naturally. That is why, periodic control and
replacement is necessary. In heat pump HPSW an insulated anode was used which
allows for preliminary control of its consumption with no need to disassemble. System
for measuring the state of anode is built into the device’s controller. The measurement
is carried out automatically once a day. In case when insufcient protection is detected,
a message about the need to replace the anode will appear on the panel. It is also
possible to verify the state of anode using universal meter.
To verify the state of anode:
- disconnect the power supply (leave device lled with water),
- remove the casing cover,
- disconnect the anode wire from connector joint,
- use universal meter to measure protective current between an anode and
a cylinder’s jacket (pic.).
If the value of measured current exceeds 0,3 mA, anode provides sufcient protection.
In other case, unscrew the anode, evaluate its state of use, and if needed exchange it.
