Air Source Heat Pump Water Heater
3 Working Principles and Advantages
3.1 Schematic Diagram of the Air Source Water
Heater
Figure 3-1 Schematic diagram of the air source water heater
3.2 Brief Introduction to Principles
The air source water heater unit is designed based on the heat pump
principles. It consumes a part of electric energy as a supplement, and by using
the thermodynamic cycle, absorbs heat from the low-grade energy (air source)
environment, and transfers the heat to a condenser through a compressor, and
releases it to the water inside the water tank. In this way, the water is heated up.
The working principles of an air source water heater are the same as those
of a heat pump air conditioner. A heat pump air conditioner absorbs heat from the
natural environment and transfers it to the indoor air; however, the air source
water heater uses the absorbed heat to heat up domestic water. The air source
water heater is a novel, efficient, energy-saving, and environment-friendly heater
product.
3.3 Advantages
(1) Efficient and Energy-Saving
The outdoor unit of this product adopts an electronic expansion valve for
9
Page 15
Air Source Heat Pump Water Heater
adaptive control. It automatically adjusts its opening size based on the unit
operating conditions, and uses the heat in the air to heat up domestic water, so
that the unit always runs at optimal performance as well as ensuring reliability.
This unit adopts inverter 2-stage compressor and the capacity can realize
stepless adjustment. EER is much higher and noise is lower under low-frequency
operation; rapid heating can be realized under high-frequency operation. Heating
capacity is improved by 40% above compared with common heat pump water
heater.
The water tank adopts an externally wrapped microchannel heat exchanger,
and is in planar contact with the inner container, which features higher efficiency
in heat exchange and a high pressure-bearing capability. Effective
thermally-conductive materials are used between the microchannel heat
exchanger and the inner container of the water tank to enhance heat transfer.
In testing conditions of the unit, the coefficient of performance (COP)
reaches up to 3.0, and the operating costs are more economical than
conventional heaters.
(2) Reliability and Durability
The unit adopts heap pump water heater specialized inverter 2-stage
compressor, which provides a powerful heat for the air source water heater. The
unit can produce 55℃ hot water reliably under -25℃ ultra-low ambient
temperature.
The insulated water tank adopts the advanced stainless steel inner port,
equipping with the anticorrosive design for the super-long magnesium. The
complete unit is with multiple kinds of protection.
(3) Simple and Convenient Installation
The installation is not subject to any environmental limitation. The unit can
be installed in the kitchen, balcony, garage, storage room, or basement
according to actual living conditions, and requires no special care. It applies to
places such as household use and villa suites. It is a no-loop waterway system,
and can be easily and conveniently installed.
(4) Luxury Configurations
The unit is equipped with a high-end ultra-thin touch-wired controller, which
10
Page 16
Air Source Heat Pump Water Heater
provides five heating modes: Hot water, Save, Preset, Night and E-heater modes.
The unit provides a proper water temperature range from 35°C to 55°C. It
provides functions such as timer switch, "Rapid" and "i-know".
(5) Intelligent Defrosting
The unit provides the antifreeze and automatic defrosting functions, which
effectively solve the problems such as heat exchanger freezing, frosting, and
sewage caused by defrosting.
(6) All-Weather Applicable
Supplies hot water all year round regardless of nights or rainy weather.
4 Installation Precautions
4.1 Importance Notes
(1) The air source water heater must be installed by professional personnel
by abiding by the national wiring code and following the instructions in
this guide.
(2) For installation or migration of the air source water heater, please
contact your local service centers authorized by Sinclair. In the case of
anair source water heater installed by any party not authorized
or designated by Sinclair, Sinclair shall not undertake any responsibility
for any fault or problems caused the air source water heater.
(3) If the user installs the air source water heater using self-prepared
installation materials, Sinclair shall not undertake any responsibility for
any loss caused by improper running and use of the air source water
heater due to pipe leakage, fall-off, or insecure installation.
(4) The quality of water heated by the air source water heater meets the
local drinking water health standards. If well water, groundwater, and
seawater are used, the depletion of the Mg-Stick in the water tank may
be accelerated, thereby shortening the lifespan of the unit.
(6) The water processed by the ion exchange water softener accelerates
the depletion of the Mg-Stick in the water tank. Therefore, you are
advised not to connect the water inlet of the air source water heater to a
water softener.

with fast heat dissipation, e.g. aluminum plastic tube is not suggested.
(2) Water inlet and outlet pipe installation
Water inlet pipe shall install safety valve, filter and cut off valve, installation
sequence shall accord with unit installation diagram. Water outlet pipe shall have
at least one cut off valve.
To drain or clean the water tank, add a 3-way and a cut off valve in water
outlet of water tank; If the water tank is far away from user water use site (hot
water pipe is ＞20m), or water use site of all hot water is lower than water inlet of
the water tank, installation is needed.
(3) Drainage pipe installation
As Figure 8-1 is shown, add a 3-way valve in cold water inlet pipe, then
connect the 3-way connector and floor drain with pipeline, meanwhile the
connection side of drainage pipeline and floor drain shall be lower than water
tank bottom, otherwise, water cannot be discharged completely. A cut off valve
must be installed in drainage pipeline, and the cut off valve must be installed in
places where the user is accessible.

the unit shall be connected to the inlet of the water tank via a stub of PPR as
Figure 7-5 is shown. The other end of the safety valve is connected with running
water pipe. To ensure usage safety, sequence in Figure 8-1 shall be strictly
obeyed.
Cut off valve or check valve (one-way valve) shall not be installed between
safety valve and the water tank, otherwise, safety valve shall not work normally,
water tank error might occur.
During heating operation process, safety valve dripping water is a normal
phenomenon of pressure relief. Under standby status, if the safety valve keeps
dripping water, please check if water pressure is too high (not over 0.7MPa). If
water pressure is higher than 0.7MPa, install stabilizing valve correctly according
to “(6) Stabilizing valve installation”; if water pressure is below 0.7MPa, please
check and replace safety valve.
Safety valve must install diversion tube and be reliably fixed to prevent
falling off; lead the drainage hose to floor drain downward naturally and properly
without bending or any twine. After that, the surplus hose must be cut to avoid
water in drainage hose getting frozen due to blocking of drainage or low
temperature.
To avoid any inconveniences or property losses due to water leakage or
safety valve discharging water which is resulted from improper connection of
water pipe, water tank and safety valve shall not be installed inside the room or
balcony which is without discharge floor drain.

14 Performance of the Unit
14.1 Heating Capacity
During heating, the unit will absorb the heat from outdoor air constantly and
then release the heat to water for heating the water inside the water tank. Once
the outdoor temperature is decreased, the heating capacity will also be
decreased. Figure 14-1 and Figure 14-2 are the correction diagram of water
generation capacity under different mode and the COP curve diagram with the
change of ambient temperature (only for reference).
The unit’s water generation capacity will increase with the increased of
ambient temperature. Under the same ambient temperature, the maximum water
generation capacity is under Rapid mode, and then the Hot water mode. The
heating time under SE mode is longer. Under the normal circumstances, the
required time for heating 200L water is 1-3 hours in summer, 2-5 hours in spring.
The required time in winter is longer. Under Save mode, the time for heating
200L water will not longer than 7.5h (under -25 ambient temperature).
After pressing “Rapid” button on the wired controller, the heating speed will
be increased, and then power consumption will also be increased. If selecting
“SAVE” mode, the heating speed will be decreased, and the power consumption
will also be decreased. The defaulted mode after ex-factory is Hot water mode.
35

Air Source Heat Pump Water Heater
Figure 14-1 Correction diagram of capacity
Figure 14-2 Correction diagram of COP
14.2 Operating Performance
(1) Defrosting
1) If frosting appears during water heating, the unit automatically
enables the defrosting function to improve the heating effect.
2) When defrosting runs, the unit stops running the fan;
3) If defrosting runs in high ambient temperatures (> 10 °C), the unit is
running improperly. In this case, please report for repairing.
(2) Starting the unit after long-time shutdown
If the unit is not used for a long time, turbid fluid may come out from the tap
when the unit is started again (or started for the first time). This is a normal
phenomenon. Wait a moment, the turbid fluid will disappear.
36
Page 42
Air Source Heat Pump Water Heater
(3) Power outage
1) If an outage occurs when the unit is running, all tasks are stopped.
2) The wired controller has a power memory function.
3) If a malfunction occurs due to lightning or car radio, manually cut off
the power switch, and then power on the unit again.
(4) Power memory function
Every time before the power of the water heater or wired controller is cut off,
the wired controller automatically memorize the power switch status of the unit.
After the power is restored, the wired controller sends power-on/power-off
signals to the water heater according to the status memorized before the power
is cut off. This ensures that the unit can run according to the original status after
the power is restored.
15 Operation Notices in winter
(1) Before starting the unit which has not been used for a long period or in
quite low temperature in winter, energize it at least 8h ahead.
(2) Do not disconnect the power supply when the outdoor temperature is
quite low in winter, otherwise the automatic antifreeze protection will fail
to work. Under low ambient temperature, anti-freezing operation
function of the unit will conduct heating for anti-freezing before water
temperature of the water tank come near to freezing point, and it stops if
water temperature of the water tank rises to safe temperature. But the
auto anti-freezing operation function of the water tank is invalid for water
inlet/outlet pipe of the water tank. If ambient temperature of unit
installation location is below 0℃, pipeline anti-freezing tracing belt must
be installed and ensure the aforementioned belt is energized. If the
water tank is installed outdoor inevitably, shorten outdoor piping length
as much as possible, including refrigerant connection pipe and water
inlet pipe of the water tank, otherwise, heat dissipation loss of the unit is
big, power consumptive and water system is easy to be frozen. Special
attention shall be paid to thermal insulation blind spot on local valve
connection location and water pipe curve, strengthen the thermal
insulation, otherwise, local pipe will be frozen.
37
Page 43
Air Source Heat Pump Water Heater
(3) When the unit is not to be used for a long period, drain the water tank
and pipe according to discharge operation, otherwise, water system will
be damaged. After draining water and to reuse the unit again, pours
water to the water tank fully before starting up. Please refer to water
input and drainage operation of the water tank.
Warm hint:
If it’s not convenient for operation or there’s hazard, please contact the local
appointed dealer or appointed service center directly. We will appoint profession
persons to check, debug and clean the unit, and discharge water and fill the
water tank with water for you.

39
Page 45
Air Source Heat Pump Water Heater
Figure 16-1 Mg-Stick replacement
NOTICE!
The Mg-Stick must be replaced by professional maintenance personnel.
Directly contact your local dealer or authorized service center of SINCLAIR,
and SINCLAIR will dispatch professional personnel to provide services.
16.4 Safety Valve Maintenance
In the heating process, when the inner container of water tank is in
overpressure, a small amount of water may be discharged through the safety
valve, which is a normal phenomenon. However, if a large amount of water is
discharged through the safety valve or even pipe vibration occurs and abnormal
noise is caused, contact Sinclair authorized maintenance centers. The
possible causes of this problem are as follows: The safety valve is damaged;
the water replenishment pressure is higher than the maximum working pressure
(0.7MPa) of the water tank, which occurs generally when pressure
reduction is not performed on the tap water. In normal conditions, the tap
water pressure is around 0.3 MPa. If a booster pump is used to replenish
water, the water replenishment pressure may exceed 0.7 MPa. In this case, a
pressure reduction valve needs to be added to the tap water replenishment
pipe to reduce water replenishment pressure.
Open the safety valve’s handle to check whether it is blocked on a regular
(about once a month) basis. If it is blocked, contact the authorized maintenance
40
Page 46
Air Source Heat Pump Water Heater
center for check or replacement. Perform sewage disposal by following the guide
on a regular (about once a year) basis.
16.5 Maintenance of the Unit
(1) Check the water inlet and outlet for blockage periodically. If so, eliminate
it.
(2) Check the water circuits, pipe connectors and valves for blockage,
damage or leakage, and if the filter has been blocked by impuritie.
17 Precautions for Safety Usage
(1)
For comfort usage, it’s suggested to use shower head with flow rate of
6～7L/min.
(2) User should have regular check and maintenance for heat pump water
heater, if there is abnormal condition, please immediately contact to
Sinclair after-sales service for help so as to guarantee normal, safe

There is water drained from
safety valve.
During heating, if pressure of inner tank of the
water tank is too high, it will discharge little
water to release pressure through safety
valve, which is a normal phenomenon.
However, if water of big outflow occur in
safety valve obviously, even result in vibration
or instruction concerning use of the appliance in a safe way and
understand thewithplaynotshallinvolved. Childrenthe hazards
bymadebenotshallmaintenanceappliance. Cleaning and user
children without supervision.
(10) In order to prevent the hazard due to the invalidation if electric heating
of water tank, the electric heating circuit is equipped with thermostat. If
the water temperature is higher than 95℃, the thermostat will be
activated to cut off the electric heating power. However, if the electric
heating is abnormal, it needs to contact Sinclair service man to maintain
or replace it.
(11) The water inlet pressure for the water tank is 0.1MPa~0.7MPa. Before
installation, please confirm the water pressure range. And the hose-sets
should not be reused.
