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
