TO USER
Dear customers, thank you for using our products.
Here is some matters need attention for you below , as improper operation or unqualified
engineering will reduce the service life of equipment, damage the unit, and even cause
safety accidents:
General procedures
1. The unit must be initially started by authorized personnel or under their supervision.
2. In order to better use the equipment, operators need to be training.
3. Operators regularly record the operation data of the unit periodically to provide
accurate data and basis for equipment maintenance.
4. The system is filled with high pressure refrigerant. During the installation, operation
and maintenance of the unit, It is forbidden to trample, collide and deform pipelines,
instruments, valves and joints to avoid leakage of refrigerant.
5. When the heat pump occur failure protection, please find out the reason according to
the controller display. Restart the unit after have the solution, otherwise the unit will damage.
6. The refrigerant in the system of the unit is tasteless and non-toxic, but when there
is a large amount of leakage in the closed space, it can cause asphyxiation and produce
toxic gas in case of fire. When it is found that leakage cannot be stopped, it is absolutely
prohibited to fire, and please stay away from the unit, ventilate the scene, inform
relevant personnel to cause prevention.
Installation guide
1.Equipment installation, debugging and maintenance must be operated by professionals.
2.There is obstacle distance requirement for the unit installation. Please refer to the
product manual for details.
3.The outlet water pipe of the unit must be installed with a flow switch and connected to
the control part of the unit, otherwise the heat exchanger pipe will be damaged by frost
crack.
4.The water inlet pipe of the unit shall be equipped with a detachable pipe filter of more
than 40 mesh, otherwise the sand particles in the water will wear through the pipe wall
of the heat exchanger and damage the unit. Please check and clean water filter monthly.
5.The circulating heated water of the unit must meet the national residential water standard,
otherwise, the untreated water will corrode copper pipe and the reduce the heat transfer
effect. Please inspect into the water quality of the unit regularly.
6.Please check water system has been cleaned and there is no leakage before the heat
pump water side heat exchanger is connected to the water.
Operation requirement
1.Don’t adjust the set values of parameters of the heat pump (except technical personnel ).
2.After the first start up or long shutdown, check whether the electrical equipment
connection is tight; the valves are open before starting and the compressor must be
powered on for more than 8 hours before standby heating. Otherwise it will cause
irreversible damage to the compressor.
