3 Operating Principle
3.1 Operating Principle
Air source heat pump water heater is developed based on the principle of reverse Carnot cycle.
Driven by a small amount of electricity, with refrigerant as the carrier, it can continuously absorb low
grade heat (-26°C~46°C) in the air, and then transform the heat into usable high grade heat, which
will be released into water so as to generate domestic hot water (Default temperature is 55°C, and
maximum temperature is 70°C), which will be carried by the hot water pipes to users.

Notices:
Generally, air source heat pump water heating system is composed of direct recurrent model water
heater and insulating water tank, including auxiliary devices such as connecting pipes, water pumps,
valves and so on.
Air source heat pump water heater mainly consists of compressor, water side heat exchanger, air
side heat exchanger, throttling device, waterway regulating valves and so on.
3.3 Process Descriptions
Water heater is connected with power. Then it starts to work and enter the heating process. The
low temperature and low pressure refrigerant gas is compressed into high temperature and high
pressure gas after being absorbed into compressor. Then it gets into the water side heat exchanger
and exchanges heat with domestic water. The refrigerant after heat exchange becomes liquid,
and enters into air side heat exchanger after its pressure and temperature is lowered by electronic
expansion valves. It will exchange heat with surrounding air inside the air side heat exchanger, and
evaporate into low temperature and low pressure refrigerant gas, and then back to compressor for
the next circulation. Meanwhile, the domestic water which exchanges heat with refrigerant inside the
water side heat exchanger is heated and ows to heat insulating water tank upon driving of the water
pump.

6.3 Installation Notes
Notice:
♦The design and installation of the project must be executed by qualified processional staff in
accordance with relative laws and regulations as well as this manual.
♦When installing modular units, parallel connection should be adopted. Up
to 16 water heaters can be connected in parallel at the same time, each of which
should be installed with ball valve at the water inlet to adjust water inow.
♦In different working conditions, water output would be different. As a result,
please calculate and dene the calibers of water outlet and inlet according to the
double rated ow and recommended ow rate.
(1) Installation location:
♦Installation location must bear the weight of water heater. Meanwhile
operation noise, discharge gas and condensate water won’t affect neighbors.
♦Never install units at places with ammable or explosive objects, or places
where explosive and ammable gas may leak out.
♦Never install units at places with corrosive gas, heavy dust, salt fog or oil fume.
♦Installation location should be well-ventilated and has enough space for air inlet and maintenance.
Make sure there is no obstacle at the air inlet or outlet and the air circulation is smooth.
♦Place that is convenient for connecting pipe and electrical system.
<40°

(2) Goods reception check:
♦Water heater should be transferred to the possibly nearest location from the installation location
before taken out from package.
♦Reception check should be done after the unit arrives at the installation location.
1) Check whether the attached papers and accessories are complete.
2) Check the model number and specications according to the attached papers.
3) Check whether the unit is damaged, whether the parts are complete and whether there is
refrigerant leakage.
If there is any damage or question, please contact our company or local ofce in time to get a proper
solution.
(3) Transporting and installation:
♦When lifting the water heater, add protection board on the surface that contacts with steel wire
to avoid metal plate damage. Use two steel cables that are larger than φ6 mm and long enough to lift
the unit steadily from 4 directions when transporting. The angle between the cable and the vertical
direction shall not be above 20°, while the tilt angle of the water heater shall be less than 15°. Handle
carefully to avoid erce collision. The right drawing is CH-HP40MFNM. Other units are similar.
♦Install the water heater vertically on cement block or U-steel, and secure the supporting feet
with M12 bolts. Install shock absorbing spring or rubber shock pad at the 4 corners so as to meet the
requirements for noise and shock. When building the cement block, ground screws must be 50mm
higher than the xed position. Meanwhile make sure the water drainage of water tray and the drain
ditch is smooth.
♦Before moving the water heater to the cement block, put on a rubber pad which is 20mm’s thick
to prevent shock and absorb vibration. Then move the water heater onto the cement block, with the
rubber pad pressed underneath. Then x 4 ground screws with spanner. Make sure screws are xed
tightly and the water heater is placed vertically. The tilt angle after installation is finished shall be
within 5°.
♦When multiple units are installed together, make sure there is enough space for repair and heat
exchange. Airow short circuit is forbidden, because it will degrade the heating performance or even
damage the units.
♦In case that the water heater is not under the lightning protection of the building, then lightning
protection measures should be taken according to the existing local national standards.
(4) Water pipe connection:
♦The design and construction of water system must comply with the current national and related
design standards of water-heating system.
♦PPR pipes are recommended, yet expansion of pipe between the main unit and water tank
should be considered. Please calculate and determine the calibers of water outlet and inlet for direct
heat model units according to double rated ow and recommended ow rate. The table below shows
the recommended specs for PPR pipes:

♦If pipes are made of metal such as steel or copper, the unit must be connected with PPR
connecting pipes. Then connect units with metal pipes through the PPR connecting pipes.
♦Water pipes should be installed straight and plumb with appropriate pipeline arrangement to
avoid possible bending.
♦Filter (above 30 mesh) must be installed at the water inlet to prevent blocking of tube in tube
heat exchanger inside the unit. Clean them periodically.
♦Usually service valve needs to be installed in front of the electromagnetic valve on the system
pipeline for future maintenance. For the convenience of system cleaning, install drainage valve and
discharge valve at the lowest point and the highest point of the system respectively.
♦When pipe connection of the water system is completed, perform water pressure leak test and
drainage according to relative HVAC standards to make sure the water pipes are clean inside and
without rust or dirt. Pipelines as well as the heat exchanger and water pump of the units can’t be
blocked; otherwise, units may get damaged.
♦After the water system passes the leak test, perform heat insulation at the inlet and outlet pipes
as well as the water replenishing pipes in order to prevent heat loss or frost cracking of pipes in
winter. Heat insulation is necessary for each valve.

6.4 Installation of Water Level Switch
The water flow switch is used for measuring water flow of the circulating water side. When the
circulating ow reaches its closed ow, it is used to output closed loop circuit; and when water ow is
smaller than a certain ow, water ow switch will send out a break-off signal to stop the units and thus
protect compressor, water pump and other important components.

(1) Usually water flow switch contains detachable paddles that are 45mm, 65mm, 75mm or
85mm’s long and 16mm’s wide. The paddle can be trimmed conditionally during installation.
Please make sure the rear part forms an arc that matches the pipe and the bottom of the
paddle should be 10%-20% above the pipe central line, thus avoiding collision between the
paddle and the inner surface of pipes as well as other objects inside.
(2) Please make sure that the ow direction is consistent with marks on the water ow switch box
cover;
(3) Water flow switch should be installed on horizontal pipes, and make sure that size of A in
above diagram is at least 5 times larger than pipe caliber;
(4) The wiring distance between the water ow switch and the units should be less than 10m, and

the water ow switch should be installed at a position where wiring is easy;
(5) Water ow switch project should be added by rain-proof equipment (Rainproof cover should
be set up);
(6) Water ow switch installation size is G1" .

Water tank installation refers to the tting-in between water tank and pipes as well as water level
switch. Pay attention to the following points during installation:
(1) User intake should be at least 50mm above the cyclic outlet in order to avoid possible water
shortage during operation;
(2) If users utilize water that is over 60°C, water-softening device MUST be installed.
(3) Overow port should be at least 50mm above the highest level oat of water level switch to
avoid water leak of the water tank; and the overow port must be connected with the hose
tube leading to the oor drainage;
(4) Hot water inlet and user backwater port can’t face the water level switch squarely in case the
inlet water ow lashes against the water level oat, which will cause error of the switch.
(5) If electric auxiliary heater is installed on the water tank, make sure that electric auxiliary heater
is located lower than the user intake.
(6) Temperature sensor blind pipe should be lower than the user intake, and make sure the inner
side of the blind pipe is dry and without moisture.

Notice:
(1) Hydraulic calculation must be taken after water pipe is selected. If the water side pipeline
resistance is larger than the delivery lift of the selected water pump, then select a larger water
pump or increase the water pipe to a bigger size.
(2) In winter when the ambient temperature is rather low or the unit is not started for a long time
(24hours), supply power to the unit for at least 8 hours before startup.
(3) In winter when the ambient temperature is rather low, the power can’t be disconnected after
