Dear Sir:
In order to use this machine safely, please read this INTRUCTION MANUAL carefully
before using and installation. Heat pump water heater is a professional machine, it may
cause damage or hazard when wrong installed, it should be installed by a competent
person in accordance with the relevant standards for the country of use.
WARNING:
ELECTRICAL POWER MUST BE SWITCHED OFF
BEFORE STARTING ANY WORK ON JUNCTION BOXES
1.Before installing the heat pump, please ensure that the electrical supply corresponds
to the specification indicated on the unit's rating label before proceeding with the
connection in accordance with the wiring diagram supplied. Please check carefully
on the rating label and the wiring diagrams that pasted on each heat pump unit.
2.The unit must be EARTHED to avoid any risks caused by insulation defects. It is
forbidden to start any work on the electrical components without switching off the
electrical supply to the unit. Electric leakage switch protection device MUST be
installed.
3.It is forbidden to start any work on the electrical components if water or high
humidity is present on the installation site.
4.When the unit is being connected, ensure that no impurities are introduced into the
pipe work and the water circuits.
5.All maintenance or repair of the heat pump must be performed by competent
technicians.
6.It could be hurtful when generated hot water reaches 52 ℃, please mix with cold
water before using.
7. To prevent any damage to the fan or any accidents, it is forbidden to put your
fingers or any other objects into the air outlet. Kids or children should be kept
away from the heat pump.
8. This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
9.Children should be supervised to ensure that they do not play with the appliance.

Product Introducing
Safe and Reliable
Unlike traditional electric water heater, heat pump water heater do not directly generate
heat by electricity , it use less electricity to move heat from one place to another , electric
circuit is separated from water circuit ,which is also not easy for electric shock,
inflammable , explosion and poisoning ! Safer and more reliable!
Highly efficient & Energy saving
Heat pump water heater absorb plenty of heat from free ambient air, and can supply same
hot water volume as electric heater. Electricity consumption is only 1/4 compared to
electric heater, very energy saving!
Environmental Friendly
Heat pump not only use less electricity to get heat from ambient air , but are also able to
combine using with solar equipment , will not cause pollution and no poison gas
exhausting .
All Round The Year Hot Water
Heat pump water heaters are not affected by seasonal climate, provide hot water all year
round even in cloudy or rainy days!
Durable and long-lasting time
Heat pump spare parts such as compressor and 4-way-valve are made by famous brand
manufacturer , and casing panel is corrosion resistance, very durable and long-lasting
time .
Convenient Installation
Installation site for heat pump can be the roof, the garage , the kitchen, the storing room ,
the basement and so on, very convenient on installation .
Wide Application
Heat pump water heaters are applicable for family, factory, school, hotel , hospital , and
laundry ,etc. Wide application for different using request.

Work principle
The low temperature and low pressure refrigerant gas come from the evaporate to the
compressor, After the compressor compress it , the refrigerant gas became high
temperature and high pressure.Then the gas come into the water condensation into
liquid, emit a lot of condensation heat,condensing heat absorbed by water, making the
water temperature increased, and then the liquid refrigerant come through the expansion
valve, with a fan , the evaporate heat in the air, after all evaporation , the low pressure
compressor refrigerant gas inhalation in the compressor, after working through the
compressor, a high temperature and high pressure of the refrigerant gas from the
compressor to exhaust emissions, such reciprocating cycle.

3.8.1 Second Set Point available when S1 switch has well connected.
At the same time, water temp set point setting decided by ambient temp, Parameter 31 and
Parameter 32. (Both 31 & 32 Parameter would be adjusted)
Parameter 31 (maximum setting range 50~60 °C)
Parameter 32 (minimum setting range 20~40 °C)
A. When ambient temp < 5°C, set point temp refer to the data of Parameter 31
B. When ambient temp >15°C, set point temp refer to the data of Parameter 32
C. When 5°C ≤ ambient temp ≤ 15°C, Set point temp = Data of Parameter 31- (Data of
parameter 31- data of parameter of 32)/(15-5)*(Ambient temp -5 )
For example, when ambient temp is 18 deg c, Parameter 31 data is 60 deg c, Parameter 32
data is 20 deg c.Then set point temp =60-(60-20)/(15-5)*(18-5)

3.8.2 When S1 disconnected, set point temp control by LCD controller. (Refer to the setting of
Parameter 20 (default setting 40 deg c).
3.8.3 Heat pump will turn on when S2 switch has well connected.However, S2 well connected,
and suddenly press the off button on the LCD controller.Heat pump will stop for 3 minutes.
After 3 minutes heat pump continue to turn on if S2 Still has been connected.
3.8.4 The timer function is out of validity when S2 switch is connected.
3.8.5 Heat pump turns off when S2 switch is disconnected. Meanwhile, need to use LCD controller

Installation instructions
1. Unit installation
1).Installation location
Host unit
1Should be installed in a larger & well-ventilated place.
1Installation location should ensure unhindered access outlet (inlet & outlet shown as
below).
1Install gutter or set up positions near the outfall, to facilitate the drainage.
1The installation base or bracket should be a steady, to ensure the smooth operation of
generating units.
1Make sure the unit is vertical after installation, and no incline.
1Make sure not to install the host unit in the any conditioner of pollution, corrosive gases,
sun and fallen leaves, etc.
1Installation location must not next to place of incendive , easy-explosion and fire .
1Installation must pay attention to the distance between the barriers shown in below
picture (pay attention to arrow direction).
Water tank
1Water tanks should be placed where ambient temperature is above 0℃ .
1Can be installed outdoors or the top of the building (based on the size of water tanks and
the load-bearing capacity of the building and so on).
1Do not have water tanks installed in the pollution, corrosive gases place.
2).Unit installation
1Units base can be installed as cement concrete structures, steel brackets can also be used,
add the shockproof rubber pads , make the base surface flat.
1Units can be designed based on the working performance.
(See Table of technical performance parameters)
1Unit should have drain or drainage inlets.
1Normally required to install in the place where setted cement concrete base.

Installation instructions
2. Pipeline connecting
Installation notes:
1Water drain pipes, overflow pipes should be installed next to the drainage inlets to
facilitate drainage, vent valve should be installed on vent pipes.
1Repair valve should be installed in front of the electromagnetic valve on the pipeline
system, which is convenient for future repair.
1User water pressure should less than 0. 6 Mpa.
1All pipelines should choose metal pipe (such as stainless steel, with Lining Plastic and
lining stainless steel and thin-walled copper pipe or, etc.). The use of plastic pipe
(such as the PP-R, ABS, etc.) should consider the pipeline expansion between the host
unit and water tanks .
1Water supply and pause valves may need to keep warm in the winter (according to the
local winter temperature) to avoid the broken of water supply and pause valve.
Water system installation
1All the pipeline tubing should be matched as shown on the manual, and in accordance
with national corresponding construction standards.
1Installation of water pipes should be straight and flat, pipeline collocation should be
rational, ensure to minimize bending; reduce the resistance loss of the water system.
1Pipeline and connecting parts are not allowed a leakage phenomenon.
1After the installation of circulating pipe between tap water pipes, host unit and water
tanks ,should carry out water leakage testing, and eject the sewage to ensure the sy
stem's cleanness.
1If no water leakage, keep the hot water pipe warm.
