1. Attentions
Be sure to read this manual before use. The installation, dismantle
mentand maintenance of the unit must be performed by qualified
personnel. It is forbidden to do any changes to the structure of the
unit. Otherwise injury of personor unit damage might happen.
The power supply to the unit must be grounded.
Make sure the power supply to the heat pump unit is off
Before any operations are done on the unit.
When the power cord gets looser or is damaged, always get
a qualified person to fix it.
Keep the unit away from the combustible or corrosive
environment.
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

Use a dedicated socket for this unit, otherwise malfunction may
occur.
Do not touch the air outlet grill when fan motor is running.
Water or any kind of liquid is strictly forbidden to be poured into
the product, or may case creepage or breakdown of the product.
When running the unit, never cover clothes, plastic cloth or any
other material that block ventilation on the product which will
lead to low efficiency or even non-operation of this unit.
When the power cord gets loose or is damaged, always get a
qualified person to fix it.
It is mandatory to use a suitable circuit breaker for the heat pump
and make sure the power supply to the heater corresponds to the
specifications. Otherwise the unit might be damaged.

2. Installation
(1) Heat pump installation location and attentions
* Heat pump is not allowed to be installed in the place where combustible gas
may leaks.
* Heat pump is not allowed to be installed in the place where there is oil or
corrosion gas released.
* Heat pump should be installed in a open space, and good ventilating.
* Heat pump each side to wall or barrel should be keep certain distance, air outlet
to barrel distance should ≥2m, air inlet distance to wall or barrel≥0.5m, bottom
distance to ground ≥0.5m, other side distance should be enough for installation
or repairing.
* Heat pump should be installed on concrete basic or steel bracket, and anti-shock
pad should be put between heat pump and basic or bracket. Then use expansion
bolt to fix heat pump on bracket.
* Water drainage pipe and ditch should be set around heat pump and water pipes
and water tank. When testing or repairing, maybe need drain plenty of water,
and when heat pump is working, there are some condensed water flow down.

5
(2) Installation diagram and tips (for reference only, installation shall
be based on actual project demand)
*for hot water and floor heating

6
*for heating/cooling
Tips for installation related to the water pipe part:
*Install a valve at the highest point of each water circulations for
releasing air from water system.
* A Y filter is very important in front of circulating water pump of heat
pump.
* If more heat pumps installed in one water pipe system, the
connection of these heat pumps can’t be in series, only can be in
parallel or independent.

(3) Pre-start up
①Checking before pre-start up
●Check if the water pipe are connected well and if there is any
leakage. The water supply valve are open.
●Make sure the water flow is enough and meet the demand of the
heat pump selected and water flow smoothly without air . In cold area,
pls make sure that the water flow is without freezing
●Check if the power cable is connected well and properly grounded.
●Check if fan blade is blocked by the fixing plate of fan blade and fan
blade protecting grill.
●Check if the tank has been filled with water or enough water volume
that can meet the demand of heat pump running
②Pre-start up
●After check completely and confirm no problem for installation, the
unit can be power to start up .
●After connect power supply, heat pump delay 3mins to start. Check
carefully is there is some abnormal noise or vibration or if the
working current is normal or if water temp increasing is normal.
●After the unit is working properly for 10 minutes without any
problem, then the pre-start up is usefully completed. If not, pls refer to
Service and Maintenance Chapter to solve the problem.
If everything above is OK, the unit can start up. If any of them fails, please improve it.

(2)3.2 Press this button, can enter timer of ON/OFF setting, combine
“+”and “-“button, can set timers.
(3) Operating
Operating panel get electricity
When heat pump power supply is supplied, operating panel and PC
board will get electricity, then display panel displays, background

light is very weak, all buttons are locked now, any touching is
invalid.
Unlock buttons
Press “power” button for 3sec, when hear “Du” voice, move finger,
now background light is strong, all buttons are unlocked, the lock
symbol disappear. (if there is not operating on buttons for 60sec,
buttons will be locked automatically, and displays lock symbol)
Turn on/off heat pump.
Press “power” button, if operating panel shows off state, will turn
on heat pump.
If operating panel shows on state, will turn off heat pump.
Water tank temperature setting (L3 or L4)
Except HH series, other series have two way to set water tank
temperature:
Way 1:
Under on state and main interface, press “+” and “-“ button, can
adjust current working mode water tank preset temp. The preset
water tank temp is the left one temperature, the real water tank
temp is the right one temperature. When setting, the left temp will
change, and display L3 or L4 below it.

14
Way 2:
Refer to “Table 3: user parameters query and setting” in P15. All
user parameters can be set by the same way. Floor heating water
temperature only can be set by this way.
(4) Parameters query and setting operation
① Working status parameters and history error code query
How to enter? Under main interface, press ”M” button, can query
the working status parameters and history error codes.
