1. Preface
This manual includes all the necessary information in regard to installation, debugging, discharging
and maintenance of your unit. Ensure the contents of this manual are read carefully before the unit
is opened or maintained.
Read these operation and installation instructions carefully. Positioning, installation and
commissioning must be carried out by trained personnel working in accordance with these
instructions.
If the heat pump is to be installed at a later time, keep it free from damage, rust and abrasion by
using the following methods:
-All access points such as water connections must be sealed correctly
-The unit must be free from sun exposure, and kept in temperatures of under 45°
-Ensure a dust build up does not occur on the unit to avoid dirt reaching the evaporator
It is vital that all instructions are adhered to at all times to keep the warranty. The unit can only be
installed or repaired by a qualified installer and authorised dealer. Maintenance and operation
should be carried out according to the recommended frequency. Only genuine standard spare
musts must be used. Pictures and drawings in this manual are for your information only. The
manufacturer has the right to change or improve the product when required, without prior
notification to the users of this device.

2. Information on the Evo Comfort
2.1 Evo Comfort Technology
The Evo Comfort extracts heat from ambient air and transfers it to water. By circulating the water, the
energy is used to warm the house efficiently. Compared with oil boilers, gas boilers, and electrical heaters,
the heat pump is the best solution by providing high efficiency, safety, and environmental protection.
The Evo Comfort is ideal for luxury domestic and commercial applications that require space heating and
cooling and hot water, offering a unique high efficiency solution to heating, cooling and hot water using the
one heat pump.
The Evo Comfort provides hot water up to 65°C and by combining EVI Technology, features a wide operating
temperature range with stable running performance - even in cold climates. Using Wet Injection Technology
allows the Evo Comfort to work safely with reliability at ambient temperatures as low as -30°C.

When the heat pump needs to be moved or installed again, please
entrust the dealer or qualified person to carry it out. Improper
installation will lead to water leakage, electrical shock, injury or fire.
Entrust
When the heat pump needs to be repaired, entrust the dealer or a
qualified person to carry it out. Improper movement or repair on the
unit will lead to water leakage, electrical shock, injury or fire.

4. Installation
4.1 Transit
When the heat pump is to be transported, please keep the unit
standing upright. The unit cannot be laid down, otherwise inner
parts of the device may become damaged.
If the unit needs to be hung up during installation an 8 metre cable
will be needed to do so. There must be padding of some kind
between the cable and the unit to prevent damage to the heat
pump cabinet.
DO NOT TOUCH THE RADIATING FINS BEHIND THE MACHINE WITH
HANDS OR OBJECTS!
4.2 Installation Notes
-The unit can be installed in any outdoor area which can carry heavy machinery, such as a terrace,
rooftop, the ground etc.
-The location must have adequate ventilation and be free from strong winds.
-The installation location must be free from heat radiation and fire hazards.
-Ensure there are no obstacles near the air inlet and outlet of the heat pump.
-There must be a water channel around the heat pump to drain condensing water.
-Ensure that there is enough space around the unit for maintenance.
-The heat pump can be installed onto the concrete basement using expansion screws, or onto a steel
frame with rubber feet which can be placed on the ground or rooftop. Ensure the unit is placed
horizontally.
A snow shelter is required in areas that receive snow:

4.3 Water Loop Connection
•Try to reduce the resistance to the water from the piping.
•The piping must be clear and free from dirt and blockage. A water leakage test must be carried out to
ensure that there is no water leaking before the installation can be made.
•The pipe must be tested by pressure separately. DO NOT test it together with the unit.
•There must be an expansion tank on the top point of the water loop, and the water level inside the tank
must be at least 0.5meters higher than the top point of the water loop.
•The flow switch is installed inside of the heat pump, check to ensure that the wiring and action of the
switch is normal and controlled by the controller.
•The connection between the heat pump and the construction is best to be of a flexible type to avoid
vibration transfer. The support to the water pipe must be separate, but not rely on the heat pump unit.
•Try to avoid any air from being trapped inside the water pipe, there must be an air vent on the top point
of the water loop.
•There must be a thermometer and pressure meter at the water inlet and outlet for easy inspection
during running.
•There must be drainage on the low points of the water system, and there is already drainage on the
chassis of the heat pump. The water in the system must be drained out during winter if the heat pump is
not to be used.

4.5 Water Connection Diagram
4.6 Power Supply Connection
-Open the front panel and open the power supply access.
-The power supply must go through the wire access and be connected to the power supply terminals in
the controlling box. Then connect the 3-signal wire plugs of the wire controller and main controller.
-If the outside water pump is needed, please inset the power supply wire into the wire access as well and
connect to the water pump terminals.
-If an additional auxiliary heater is needed to be to be controlled by the heat pump controller, the relay
(or power) of the aux-heather must be connected to the relevant output of the controller.

4.7 Cable and Switches
•The unit should use independent power supply, Wiring required by the corresponding table, Power
supply voltage must in line with rated voltage.
•Power supply circuit must be equipped with an All-pole disconnect device that has at least 3mm contact
opening distance.
•The wiring must be completed by professional technicians in accordance with circuit diagram.
•Power supply circuit must have earth wire, the earth wire of power should be connected with external
earth wire safely, and the external earth wire must be in order.
•The creepage protection device must be settled in accordance with the relevant national technical
standards for electronic equipment.
•The power wire and signal wire should be neatly arranged. High voltage wire and low voltage wires must
be separated and free from any interference, and they must be free from any piping and valves of the
unit.
•When all the wiring is completed, the power can only be connected after a double check.

4.8 Inspection Before Trial Operation
Check the indoor unit, make sure that the pipe connection is done correctly and that the relevant valves are
open.
Check the water loop to ensure that there is enough water inside of the expansion tank, that the water
supply is good and that the water loop has no air in it and is full of water. Make sure there in good insulation
for the water pipe.
Check the electrical wiring. Make sure that the power voltage is normal, the screws are fastened, the wiring
is made in line with the diagram and the earthing is connected.
Check that the heat pump, including all the screws and different parts are in good order. When the power is
on, review the indicator on the controller to see if there are any failure indications. The gas gauge can be
connected to the check valve to see the high pressure (or low pressure) of the system during trial running.
4.9 Trial Operation
Start the heat pump by pressing the ‘Power Button’ key on the controller. Check whether the water pump is
running, if it is running normally there will be 0.2MPa on the water pressure meter.
When the water pump runs for 1 minute, the compressor will start. Hear whether there is a strange sound
coming from the compressor. If an abnormal sound occurs, please stop the unit and check the compressor. If
the compressor runs well, look for the pressure meter of the refrigerant.
Check whether the power input and running current is in line with the manual. If not stop the unit and check
for why this may be occurring.
Adjust the valves on the water loop to make sure that the hot (cool) water supply to each door is good and
meets the requirement of heating (or cooling).
Review whether the outlet water temperature is stable.
The parameters of the controller are set by the factory, the user must not change these.
