Multi-Function Heat Pump
I. Introduction
1.1.This manual contains the necessary information of correct installation, commissioning, use
and maintenance of machinery.
1.2.In order to use this product better and more safety, please read this instruction carefully before
install and use, and focus on the installation, use and maintenance of all considerations, taking
into safekeeping for when required.
1.3.Heat pump is a highly specialized appliances, improper installation may cause damage or
danger, so the corresponding installation and maintenance need professionals, users please
contact our company special, commissioned local installation repair services department,
carefully read the installation section, and follow the prompts to install.
1. User Guide
2. Special warning
2.1.Please ask a qualified professional installation company responsible for installing heat
pumps. Installation people should have relevant professional knowledge, when self-
installation, the wrong action will result in fire, electric shock, injury, leakage, and so on.
2.2.When installation, please check the distribution power capacity, switches, sockets whether
according to our heat pump power supply requirements, details please refer to unit nameplate
or technical data sheet on the installation instructions.
2.3.When power connect, the unit must be a reliable ground connection, confirm that the ground
wire is effective. If the ground is imperfect, may result in personal injury.
2.4.Heat pump before testing, hot water side and air-conditioning side of the water system must
be full of water, drain pipes before switch on, test the hot water side and air-conditoning side
water system water pump independently, when normal, turn off the water pump exit test
status, allowed to select the operating mode into the normal state of the unit test run.
2.5.The water above 52 may cause skin burns, tank hot water need mixed with cold water
before use.
2.6.Insert any tool within the heat pump is strictly prohibited, in order not to hit the fan result in unit
damaged or an accident.
2.7.When installation, be sure to install filter in the heat pump inlet, make sure unit inlet water was
clean enough.
2.8.The units have been set parameters well in the factory, non-professionals against
arbitrary adjustments.
2.9.When the unit needs to be moved or re-installation, Please ask a qualified professional
installation company for help.
2.10.Any self-modification or repair is forbidden, if repair not properly, may result in fire, electric
shock, injury and leakage incidents, you should ask agent or professional to repair.
3.Note
3.1.Please confirm that the drainage pipe is smooth outlet, improper piping installation will result
in water leakage, or wet the furniture.
3.2.Confirm whether already install the leakage protection switch, or else may result in electric
shock.
3.3.Prohibiting installed in the position of combustible gas leaks.
3.4.Ensure the installation base, lifting is solid and reliable enough.

Multi-Function Heat Pump
3.5.Please correct connect the cable, if the cable connection error, it may damage the electrical
components.
3.6.Before installation, you should not expose the unit in water or other moisture, it may cause
short-circuit the electrical components.
3.7 If unit in the room leaks refrigerant in the installation process, then please immediately open the
room ventilation.
3.8.The unit heat exchanger air inlet and outlet position can not be any things obstruction in and
out of wind.
3.9.The unit wire controller must be fixed at a convenient operation, dry environment, not to
rain water and the out of children , do not install in the bathroom, so as not to affect the
unit work by wet.
3.10.When the installation is completed, confirm that there is no leakage of refrigerant.

4. Work principle and function introduction
Units under the reverse Carnot cycle principle, take a small amount of electricity as driving force
and refrigerant as carrier, an endless absorption the air and water low-grade thermal energy which
is difficult to use(-15-43 ), change into available high-grade heat, achieve low temperature heat
transfer to high temperature heat; then high-grade heat energy released into the water system to
supply domestic hot water (up to 60 ), through the hot water supply pipeline transport to users to
meet the demand for domestic hot water and heating.At the same time, It also can produce more
than 7 water through the pipes transport to user terminal equipment to meet the cooling
needs.Users can choose the heat pump operating mode and temperature settings, select: cooling,
heating, hot water, cooling + hot water supply, heating + hot water supply. Mode selection and
temperature set finish, start the unit, enter into automatic operation.
The highest COP up to 7.5 or more when heat pump running.

relief devices (when installed refer to the "Third, installation, 3, pipe connection"), the
parameter value is 0.7MPa.
2) The water can drain from the pressure relief device in the
outlet pipe which should keep connected with the atmosphere.
3) The pressure relief device to periodically work to remove the
calcium carbonate deposition, and sure that device is not plugged.
4) Heat pump water heater installation is complete, the water
tank empty refer to the "three, installation, 5, trial run."
5) Design an enclosed heater which directly connect to water,
the rated pressure should be at least 0.6MPa.
6) If the devices capacity more than 15L, and can not be empty
by a outlet which install in the pipe, it should be equipped with
a kind of emission devices, which with tools to make it work.

10.3 Caution of Ground
The internal motor protector does not protect the compressor against all possible
conditions.Please be sure that the system utilizes the ground connection when installed in the
field.
10.4 Warning:
To avoid fire, electric shock and other accidents, keep in mind about these tips:
10.4.1.Only use power supply voltage indicated on the label, if you do not know the family of
voltage, contact the dealer or local power company.
10.4.2.When you use the unit by the maximum current please view the specifications, so make sure
your home's power supply (current, voltage and cable) to meet the machine's normal load
Requirements.
10.4.3.To protect the power lines. Power lines should be fixed, so that people will not be trip over or
the lines damaged by other things. Paying particular attention to plugs, which should be easily
plug into the socket, careful the plug position.
10.4.4.Do not overload wall plugs or extension the cable. Line overload can cause fire or electric
shock.
10.4.5.To ensure your safety, you must plug the power lines into the socket with a grounded
three-phase, and check to ensure your socket is accurate and reliable grounding.
