3. Heat pump unit working principle
3.1 Heat pump working process
● First, the low pressure and superheated gas in the evaporator is inhaled into the compressor then
becomes the high temperature and high pressure overheated vapour.
● Second, the overheated vapour is exhausted into the condenser and exchange the heat with the
water, then the refrigerant is condensed and becomes the saturated or over cooling high pressure
and high temperature refrigerant liquid. The water is heated up by heat pump when absorbing the
heat energy which released by the refrigerant.
● Third, the refrigerant liquid releases the pressure by passing the expansion valve, then becomes
the low temperature and low pressure liquid.
● Fourth, the refrigerant liquid flows into the evaporator and absorb the energy from the air, then is
vaporized and became the low pressure and overheated vapour. The refrigerant working repeatedly
as described above, then the water which flows through the condenser is heated up constantly, the
temperature rise and can get the hot water.

● The pipe press and flow rate should be calculated before the diameter selection.
● The hydraulic calculation should be made after the selection of pipe diameter, if the resistance is
more than pump head, then need to choose a more power pump, or choose a bigger pipe.
6. Installation of optional accessories
6.1 Selection of the water pump
- 14 -
● The circulation pump is necessary for the system operation, the power port is prepared for the pump
inside the unit.
NOTE
Please check the Electric Diagram which located inside of the unit
● The head of circulation pump = height difference between water level and main unit + total pipelines
resistance (determined by the hydraulic calculation) + pressure loss of main unit (see the nameplate
on heat pump ).
NOTE
When multi paralleled, the water pump head is subject to the worst working condition loop.
6.2 Selection of the flow switch
● The selection of the flow switch is based on the actual system, the target flow switch is
recommended. Temperature of fluid: 0-120 °C , max working pressure 13.5 bar.
● The flow switch can be installed on the horizontal pipeline or the vertical pipeline which the fluid flow
direction is upward, but should not be installed on the vertical pipeline which the fluid flow direction is
downward.
● The flow switch must be installed on a straight pipeline, there must be more than five times the
length of the pipe diameter at its two sides. And, the direction of fluid must follow the arrow on the
controller. The terminal block should be in an easy operation position, (Figure 10)
● The pannier is absolutely forbid to touch the flow switch floor, or the switch will be deformed and
invalid, (Figure 11)
A
● Please be sure that the model of target sheet is determined by the system rated flow, diameter of
outlet pipe and the adjustable range of the target(see the user manual). And the target sheet can not
contact the in-wall of pipe or other throttlers in pipe, or will cause the switch can not reset.

9. Adjusting and Initial operation
9.1 Attention
● Within 12 hours after running, please connect the circuit breaker, and make the crankcase
heater be preheated.
● Open the valve of water system, and the valve of assistant tank, inject water into the system,
and exhaust air inside.
● Do adjustment after electrical safety inspection.
● After the power is switched on, start the test running of heat pump, to see if it can function
well.
● Forced operation is forbidden, because it is very dangerous to work without protector.
9.2 Preparation Before Adjustment
● The system is installed correctly.
● Tubes and lines are putted in the right place.
- 40 -
● Accessories are installed.
● Ensure the smooth drainage.
● Ensure the perfect insulation.
● Correct connection of ground lead.
● The supply voltage can meet the requirement of rated voltage.
● Air inlet and outlet function can work well.
● Electrical leakage protector can work well.
9.3 Adjustment Process
● Check if the switch of the line controller can work well.
● Check if the function keys of the line controller can work well.
● Check if the indicator light can work well.
● Check if the drainage system can work well.
● Check if the system can work well after starting up.
● Check if the water outlet temperature is acceptable.
● Check if there is vibration or abnormal sound when the system is functioning.
● Check if the wind, noise and condensate water produced by the system affect the
environment around.
● Check if there is refrigerant leakage.
● If any fault occurs, please check the instructions first, to analyze and remove the fault.
10. Operation and maintenance
10.1 Personals shall possess professional knowledge or operate according to
professionals from our company. To ensure the well functioning, the system shall be
checked and maintained after a period of time. During the maintenance, please pay
attention to some points below:
● Control and protect the equipment, please do not adjust any settings discretely.
● Pay close attention to whether all the operation parameters is normal during system working.
● Examine regularly whether the electrical connection is loose, if yes, fasten it on time.
● Examine regularly the reliability of the electrical components, change all the failed or
unreliable components on time.
● There will be calcium oxidized or other mineral substance deposition on the surface of
- 41 -
water heat ex-changer copper coil after long period of operation, which will influence the heat
exchange performance and lead to high electrical consumption, discharge pressure
increasing and air suction pressure drop, unit hot water volume produced is less. We can
adopt formic acid, citric acid, acetic acid or other organic acid to clean.
● The dirt retention on the surface of evaporator fin should be blowed by more than 0.6Mpa
compressor air, brushed by fine copper wire, or flushed by high pressurized water, usually
one time per month; if too much dirt, we can use paintbrush dipping gasoline to clean.
● After long downtime, if we restart the equipment, we should make following preparations:
examine and clean the equipment carefully, clean the water pipeline system, examine the
water pump, and fasten all the wire connections.
● Replacement parts must use our company original accessories, can not be replaced by
other similar accessories.
10.2 Refrigerant filling
Examine the refrigerant filling condition through reading the data of liquid level from display
screen, also the air suction and exhaust pressure. If there is leakage or changing components
of the refrigeration circulation system, we have to make air tightness examination first.
10.3 Leak detection and air tightness experiment
During leak detection and air tightness experiment, never let the refrigeration system filling
oxygen, ethane or other flammable harmful gas, we can only adopt compressed air, fluoride
or refrigerant for such experiment.
10.4 To remove the compressor, please follow the following steps
● Turn off the power supply
● Exhaust the refrigerant from the low pressure end, attention to reduce the exhaust speed,
and avoid frozen oil leakage.
● Remove the compressor air suction and exhausting pipe.
● Remove the compressor power cables.
● Remove the compressor fixing screws.
● Remove the compressor.
10.5 Conduct regular maintenance according to the user manual instruction, to make
sure the unit running in good condition.
● Fire prevention: if there is a fire, please turn off the power switch immediately, put the fire
out with fire extinguisher.
● To prevent flammable gas: the unit working environment should stay away from gasoline,
ethyl alcohol and other flammable materials, to avoid explosion accident.
- 42 -
● Malfunction: if malfunction occurs, should find out the reason, eliminate it and then reboot
the unit. Never boot the unit forcibly if the malfunction has not been eliminated. If refrigerant
leakage or frozen liquid leakage, please turn off all the power switch, if the unit can not stop
buy controlling switch, please turn off the general power switch.
● Never short connect the wire for protection required device, or else, in case unit malfunction,
it can not be protected normally and will damage the unit.
