1 Product introduction
1.1 Working principle
The cold (hot) water entering the heat exchanger will do heat exchanging with air passing through the
surface of the heat exchanger to condition the air temperature and humidity. There is no (cold) hot source
for this product itself. The running mode depends on the environment temperature and the running mode
of the main unit.
Memory function
Upon power failure, some statuses can be memorized, including: mode setting, fan speed setting, fan
swing setting, temperature setting etc.
1.2 Main parts
Outlet air grille
Electric box
Filter
Outlet pipe
Inlet pipe
Drain pipe
Fan component
Panel
1.3 Working conditions
(1) The entering water temperature for cooling is suggested to be no less than 5°C, otherwise it would
lead to condensate; the entering water temperature for heating is suggested to be not higher than
65°C (normally 60°C), otherwise it would lead to corrosion of copper tubes or abnormal noise.
(2) The suggested working environment temperature for cooling ranges 16~40°C and ranges 10~35°C
for heating. Besides, the relative humidity is or less than 80%. The maximum allowable pressure is
1.6MPa.
(3) This product is a kind of comfort air conditioning, and is not allowed to be installed where there are
corrosive, explosive and inammable substances or smog; otherwise it would lead to operation failure,
shortened service life, re hazard or even severe injuries. Special air conditions are required for where
mentioned above.
2 Unit installation
2.1 Installation environment
