Product Introduction
Safe and Reliable
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.
Unlike traditional electric water heater, heat pump water heater do not directly generate
Ⅱ.Product Introduction Water heater

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.

S2 Switch----Long distance demand
6.1 Second Set Point available when S1 switch has well connected.
At the same time, water temp set point setting decided by ambient temp, Parameter
SET 9 and Parameter SET A. (Both SET 9 & SET A Parameter would be adjusted)
o
Parameter SET 9 (maximum setting range 45~60 C)
o
Parameter SET A (minimum setting range 20~40 C)
o
A. When ambient temp < 5 C, set point temp refer to the data of Parameter SET 9
o
B. When ambient temp >15 C, set point temp refer to the data of Parameter SET A
o o
C. When 5 C ≤ ambient temp ≤ 15 C, Set point temp = Data of Parameter SET 9-
(Data of parameter SET 9- data of parameter of SET A)/(15-5)*(Ambient temp -5 )
For example, when ambient temp is 18 deg c, Parameter SET 9 data is 50 deg c,
Parameter SET A data is 20 deg c.Then set point temp =50-(50-20)/(15-5)*(18-5)
S1 Switch---Second Set Point
6.2 When S1 disconnected, set point temp control by LCD controller. (Refer to the
setting of Parameter 40 (default setting 50 deg c).
6.3 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.
6.4 The timer function is out of validity when S2 switch is connected.
6.5 Heat pump turns off when S2 switch is disconnected. Meanwhile, need to use
LCD controller to switch on/off the heat pump.

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 steady,
to ensure the smooth operation of running 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).
1The air inlet and outlet can connect the φ150 air duct for air ventilation, see below pic.
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 install water tanks 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.
