Product Introduction
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.

6 Setting about S1 & S2 switch
S1 Switch---Second Set Point
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)
0
Parameter SET 9 (maximum setting range 60~80 C)
0
Parameter SET A (minimum setting range 40~55 C)
0
A. When ambient temp < 5 C, set point temp refer to the data of Parameter SET 9
0
B. When ambient temp >15 C, set point temp refer to the data of Parameter SET A
0 0
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 60 deg c,
Parameter SET A data is 20 deg c. Then set point temp =60-(60-20)/(15-5)*(18-5)
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).
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.

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.
3. Project example:
Application of heat pump water heater engineering systems have different forms. Here
are a sample of one heat pump connect to the water tank to offer hot water, only for your
reference.

Running Test and operation
1. Preparatory work before the running test.
a) Inspection of heat pump water heater units:
1Check if the unit appearance and the pipeline system were damaged during transport.
1Check if there is air exist in the water pipes, if yes, should empty all the air inside by the
manual exhaust valve and the exhaust valve on the water pumps.
1Check if the fan rotor interference the fan fixing board and fan protection net.
b) Check the electricity distribution System
1Check if the power supply same as shown on manual and rating label.
1Check if all the power supply and control wiring are all well connected, check if the wiring
is connected as wiring diagram and reliability of earth wiring.
c) Check Pipeline system
1Check the pipeline system, make sure the water supply pipes, water return pipes, pressure
gauges, thermometers, valves, water flow switch are safe and correct.
1Check if having opened all the valves that should be opened, and having closed all valves
that should be closed.
1Check if all necessary attemperators are good.
Ⅷ.Installation instructions Water heater
Due to the high temp heat pump could offer much hotter water (70-80 deg c) than the
usual heat pump (60 deg c ).
The water piping and insulation of water heat exchanger should be once or twice more
thicker and more stronger. Better to be more than 50mm.
Highly suggest to use waterproof insulation piping when the unit install outdoor.
All water piping, valve, water flow switch , circulation pump use in high temp heat
pump must be Allow to work between 0 to 100 deg c. Due to the high temp heat pump
could offer max 70- 80 deg c hot water.
The tank connect to high temp heat pump should be difference from the one use in usual
heat pump (60 deg c hot water outlet).
A air valve or a pressure relief valve should be add in the tank. And insulation of water
tank must be thicker than 100mm.
