WARNING
ATTENTION
The earth electrode of socket should have the perfect earth wiring and the rating
current should be more than 16A. Keep the socket and plug dry to avoid leakage and check
if they are connected well usually. The check ways are as follow: Put the
plug into the socket and turn on the unit, then pull out the plug half an hour later and check
if the plug is hot. If it is hot (more than 50 ℃), please have a qualified socket to replace it to
avoid the burnout or fire caused by the bad connect.
Because the water in the tank is very hot (the water more than 50 ℃will burn body),
you should adjust a suitable water temperature before spraying to the body.
If the power cable is damaged, ask the professional serviceman to use the cable which
provided by the manufacturer to replace it.
If the parts are damaged, ask the professional serviceman to use the parts provided by the
manufacturer to replace it.
The heat pump must be installed by qualified personnel to avoid improper installation which
will lead to water leakage, electrical shock or fire.
The local assembly should be the ones designated by manufacturer. The
power lines connection should be complied with the local rules.
If you need to remove or reinstall the unit, please ask the qualified personnel to make it to
avoid improper installation which will lead to water leakage, electrical shock or
fire.
The heat pump should be maintained by qualified personnel to avoid improper
maintenance which will lead to water leakage, electrical shock or fire.
Good earth wire connection is necessary for household electricity.
Electric leakage protector is necessary for household electricity.
Don't rip off any explications, labels or parameter tables on/in the unit.

3.Working principle
System diagram: High temp.
System Principle:
Refrigerant is compressed into vapor with high temperature and high pressure when it goes
through the compressor.
On the discharge side of the compressor, the now hot and highly pressurized vapor is cooled
down through the heat exchange with the water in the tank until it condenses into a high
pressure, moderate temperature liquid.
Then the pressure of the liqiud refrigerant drops as it passes expansion valve.
Finally, refrigerant absorbs heat from the surrounding air and evaporates into vapor with low
temperature and low pressure and then it goes into compressor again.
The cooled surrounding air could be blew to the rooms which needs fresh cooled air.

5> Functions explanation
1.Machine function description
Because the supplied hot water absorbs heat from the surrounding air and release the heat at heat
exchanger side. Once ambient temperature goes down, the heating capacity may
decrease accordingly.
When stopping after running, the user immediately starts the unit or turns on manual switch, the unit
will not run within 3 minutes. This phenomenon is to protect compressor by the main controller.
In heating mode, if the unit freezes, the machine will automatically defrost to promote heating
capacity.(2 to 10 minutes). Under defrosting process, the fan motor of the unit will run and
compressor will stop working.
The unit only can use tap water .Please do not use the water from any lake, river or underground
water which are not filtrated or treated.
If power is cut during machine running, the unit will stop immediately. If the unit is mis-works
because of thunder, wireless of motor car, power net fluctuation, please turn off the power switch by
hand. After the unit restarts, the user can re-press the running/stop button.
The unit must be connected with power net through current leakage protector.
When water temperature reaches 75℃, the electric heater will be off(automatic recovery). When
water temperature reaches 85℃, the fuse of electric heater will fuse (un-recovery)
In the water system will be installed the Pressure release valve. When the tank pressure reach
0.7MPa, the Pressure release valve to open sluice.

2. Choosing a proper model
For energy-saving and convenience purpose, please choose proper volume of a water tank, the
selection case is below:
80-100L is proper for 1 - 3 users.
3. Storage and transportation
Generally, it's better to use a container to transport hot water heat pumps and store them in a
suitable and dry place. To short distance carrying, please be careful and the maximum
inclination is no more than 60 ° .During transportation and storage, the ambient temp is better from
0 °C -43 °C .
Transported by forklift
When using forklift to carry the unit which must have a pallet, the operator should try best to
keep the height of forklift at a lowest level. Because the top part is heavier ,the operator needs
to take measures to prevent its overturn. To avoid any damages, the unit must stand on a flat
place.
Transport for installation
When transporting for installation, the bottom of unit needs to be added with pallet and use
a rope or belt to fix it well. By this manual carrying or forklift transportation, the inclination is no
more than 60 ° as the following picture shows. If the inclination unavoidably exceeds 60 ° ,the unit
must be kept at vertical status for at least 1 hour and then can be started for testing or
running.
Notice: The selection of a water tank is only a reference, please choose a
proper. one according to local weather and users consuming habit.

also can provide cool air to fresh the foods. One machine can realize various functions and reach an
excellent effect.

15
6. Installation and connection
1) Choose a right way of carrying the unit in.
2) Try best to carry the unit with original package.
3) If the unit is installed on the metal parts of a building, all parts need to be electric-
insulated well to fully meet related technical standards on equipments.
5. Hydraulic connection
Please notice the points below when connecting the water pipes: Try
best to decrease the resistance in water pipes.
Inner surface of whole pipe system should be clean, no rusty spots and dirts to avoid any pipe
jam. After connecting pipes, please check the leakage status of whole system to
assure there is no leakage firstly and then make the insulation.
Add one-way valve, Pressure release valve and other safety valve in water way.
The installation of water pipes have to be accordance with the requirements of the local
standard(To avoid too higher water pressure, please install a discharge valve ).
When connecting the water pipes, please prevent any pollution going into pipes.
The male specification of Pressure release valve is G3/4". After installation, please assure
that drainage pipe is open to the air.
If the discharge outlet of Pressure release valve is drainage hosepipe, please assure its
direction is down and its outlet is opened to the air. At the same time, the valve should be in a
no-frosting surroundings.
Attention items before installation
Attention
At least pull once half a year the handle of one way valve in order
to remove the sediment of Calcium Carbonate. Please confirm
the device is with no jam. The drainage outlet water temp is high,
please pay attention to it.
Please make good insulation to drainage pipe to prevent pipe
freezing in winter, which may lead to safe accidents.
The discharge mouth water temperature may be higher than e
xpected and please take care to avoid burns.

Attention
After installing the connecting pipe according to the diagram, open the water tap and the hot water
switch of the unit, make the water inject in the unit. Then there will be a large amount of air draining
off from the hot water switch(This process will lasts for 5-20minutes).When there is just water outflow
but no air outflow, it suggests that the unit is full of water, the air is
completely drained off.
Do not use stainless steel fittings to connect directly with other metals to prevent galvanic
