2. Introduction
2.1 PRODUCT OVERVIEW
KENSOL pump uses the energy in the air and transfers it to our buildings, allowing us to heat and cool
our rooms and prepare hot water.
The KENSOL series uses a DC Twin Rotary inverter compressor thanks to this technology, the unit
ensures smooth operation from -30°C to 43°C. The unique control logic allows our series to intelli-
gently regulate the water temperature in accordance with the changing ambient temperature. With
this feature, our users can enjoy comfort at a lower cost.
The control system guarantees simple and intuitive management of the entire heating system. A buil-
t-in installer and user assistant provides support for the setup and operation process.
The ability to equip the heating circuit system with additional room thermostats makes it possible
to maintain the thermal comfort level set by the user from any room. A web-based system with a
mobile application that performs management and service functions allows us to remotely operate
and diagnose our device.
Reducing and preventing global warming is an important mission for KENSOL.
By using the low greenhouse effect potential of R32 refrigerant, the device is part of the green trend.
In addition, the use of R32 refrigerant provides 20% higher efficiency at low ambient temperatures.

3. INSTALLATION
WARNING!
Do not install the heat pump near hazardous materials and areas. Do not install the heat pump under
deeply sloping roofs without gutters, exposing the unit to excessive flooding and drenching. Place
the heat pump on a structure founded on a stable foundation with adequate load-bearing capacity,
such as a concrete foundation. This will allow proper drainage of condensate and rainwater from the
base of the unit. Use anti-vibration washers for mounting. During operation of the device, condensate
condenses from the evaporator, which drains at a constant rate, depending on the temperature and
humidity of the air in the environment. The higher the ambient humidity, the greater the condensation
will be. The lower part of the unit acts as a tray that retains rainwater and condensation. The drain
holes located on the lower base plate of the unit should always be free of debris. It is required to raise
the unit to a minimum height of 30 cm.
3.1 INSTALLATION DETAILS
All criteria given in the following sections are for minimum spacing. However, each installation should
be evaluated on a case-by-case basis, taking into account local conditions such as the proximity and
height of walls and the proximity of areas accessible to people. The heat pump should be placed in
such a way as to provide clearance on all sides for maintenance and inspection.
1. The installation site of the heat pump must provide free air exchange, and the air inlet/outlet
must not be obstructed.
2. Ensure adequate drainage of condensation, for example, into an absorbent substrate.
3. Do not install the device in areas of accumulation of contaminants, such as agresive gases (chlo-
rine or acids), dust, sand, leaves, etc
4. To facilitate maintenance and troubleshooting, no obstructions around the unit should be closer
than 0.5 m. There must be no obstructions that impede ventilation within 2 m vertically of the
unit. (see Figure 1)
5. The heat pump must be installed on anti-vibration bushings to prevent vibration or unbalance.
6. Hydraulic lines must be installed with adequate support to prevent possible damage caused by
vibration.
7. The outdoor unit should be connected to the system with flexible conduits to ensure compensa-
tion for any movement between the heat pump and the system.
8. Since the heat pump operates in bivalent mode, each installation must be equipped with an
automatic peak heat source. Such a source must meet the following requirements:
a) It must be activated via a potential-free contact with the PC.
b) It must work for all heating circuits and DHW depending on demand
9. In order to protect the heat pump from impurities, it is absolutely necessary to install a magnetic
separator and a mesh filter on the return
10. The heat pump system must operate in a closed system. In addition, such an installation should
be protected against large pressure changes with a diaphragm vessel and against excessive
pressure with a safety valve (max 3bar)
11. Heating water parameters:
a) Temperature: ≤60oC

Installation, operation and use instructions for KTM 6 KW, KTM 10 KW, KTM 14 KW, KTM 17 KW 12/49
b) pH: 7-9 pH
c) Alkalinity: 60mg/l<HCO3<300mg/l
d) Conductivity: <500µS/cm
e) Hardness: 3,5-8,4 odH
12. The unit must have external antifreeze protection. This protection is designed to prevent the
circulating water in the system from freezing in the event of an electrical failure/outage.
Acceptable anti-freeze solutions:
a) Propylene glycol solution to a concentration of 30%
b) Solution of other antifreeze with corrosion inhibitors
c) Anti-freeze valves
d) UPS-based anti-freeze systems with manufacturer’s guarantee for tripping in emergency
situations
NOTE
Own solutions are not allowed as the only option to protect the heat pump from freezing
3.2 CONDENSATE DRAINAGE
Condensation occurs during the heat pump defrost process. The frequency of this process and the
rate of condensate drainage will depend on the outside temperature and humidity. The higher the
humidity, the greater the condensation will be. The lower part of the device functions as a drip tray
that catches rainwater and condensation. The drain holes, located on the lower base plate of the unit,
should always be kept free of debris..

Installation, operation and use instructions for KTM 6 KW, KTM 10 KW, KTM 14 KW, KTM 17 KW 14/49
NOTE! Avoid the use of unnecessary angle joints, connectors and constrictions. If there are
a large number of connectors, increase the diameter of the wires. Pipelines and connections
should be thermally insulated. It is recommended to connect the outdoor unit with flexible
installation elements or use expansion joints.
BUFFER TANK
In heat pump heating systems, the buffer tank performs key functions. The main tasks of buffer tank
– heat accumulation for the defrost process,
– hydraulic separation of the heat pump circuit and the central heating system circuit, ensuring the
minimum heating water flow rate required by the heat pump,
– possibility of expanding the heating system with other heat sources,
– extending the operating time of the heat pump in periods of partial demand, this affects the reduc-
tion of cycles of compressor start-ups extending its service life
– storage of thermal energy, e.g., during the cooperation of a heat pump with a PV plant
WARNING - In the case of a heating system based on a radiator system and the occurrence of
other heat sources, it is necessary to include a buffer tank in the heat pump installation.
A minimum water charge should be ensured in the installation. For Kensol heat pumps, assume the
relationship for the minimum water charge: 15L of discharge per 1kW of nominal PC power A buffer is
not required, but it is recommended to install a heat buffer on the system in parallel connection due
to a number of advantages. You can hook up the PC directly to the system, however, you must ensure
a minimum water charge and minimum flows regardless of the external control of the circuits on the
system.
DWH STORAGE TANK
The DHW tank is a tank equipped with a heat exchanger that stores hot water distributed for domestic
use.
Average daily energy consumption for DHW heating per person can be assumed from 1.5 kWh to 2.5
kWh and water consumption of 50-70 L per person.
The use of DHW circulation can increase energy consumption for DHW purposes by up to two times.
When selecting a coil tank for a heat pump, it is important to pay attention to its appropriate capacity
for the DHW demand and the heat transfer surface area.
For single-family houses, small and medium-sized heat pump installations, the minimum exchanger
area should be taken as 0.2 m² per 1 kW (recommended 0.25 m² per 1 kW) of storage charging capacity.
3.5 ELECTRICAL CONNECTION
WARNING - Electrical shock hazard may occur when working on the device.
Before installing the heat pump, make sure that all high-voltage circuits are disconnected. Contact
with these circuits can cause death or serious injury to users, installers and others from electrical
shock, and can also cause damage to property.

Installation, operation and use instructions for KTM 6 KW, KTM 10 KW, KTM 14 KW, KTM 17 KW 15/49
NOTE - Before disconnecting the wires when servicing the heat pump, mark all wires. Wiring
errors can cause incorrect and unsafe operation of the device. After servicing, check that the
device is working properly.
SUPPLY
1. If the supply voltage is too low or too high, it may cause damage and/or unstable operation of
the heat pump unit due to high inrush currents
2. The minimum starting voltage should be above 90% of the rated voltage. The allowable opera-
ting voltage range should be within ±10% of the rated voltage.
3. The wires used must be designed for permanent installation and be resistant to external
conditions.
4. The cross-section of the wire depends on the distance between the device and the switchboard.
The value should be verified by a person with appropriate electrical qualifications.
5. The electrical installation should be carried out by a person with the appropriate authorization
and in accordance with applicable national regulations.
6. All power wires should be run in insulation. The length of the stripped section of wire should not
be longer than 50mm.
7. Do not frequently interrupt the voltage supply to the heat pump, as this may shorten its life.
8. Do not unplug the wires and sensors located in the outdoor unit.
A PC<->KT-Multi communication wire is included with the controller.
MAIN POWER SUPPLY CONNECTION
NOTE - Before installing the heat pump, verify the connection power of the building and the
protection used. In addition, note that the heat pump and the controller must be protected by a
residual current circuit breaker with a tripping current of IΔn ≤30mA
1. The device should be powered directly from the electrical switchboard.
2. The heat pump should be protected by an overcurrent circuit breaker with characteristic C and
a 30mA residual current device
Recommended protection and minimum cross-section of the main power wire:
1-phase system (KTM6KW) C20A 3x4 mm²
3-phase system (KTM10KW) C16A 5x2,5 mm²
3-phase system (KTM14KW) C20A 5x4 mm²
3-phase system (KTM17KW) C20A 5x4 mm²
3. The wire should be inserted through the cable gland and plugged in according to the wiring
diagram.
