4. Features
4.1 Titanium heat exchanger
a. Excellent prevent eroding material,keep the machine long life.
b. High energy efficiency.
4.2 LCD display and build in high pressure meter in refrigerant side
User can see the machine running parameter and the state quickly.
Engineer can see the machine discharge pressure quickly, get hold of the machine
running reliablity .
4.3 About the 3-minute protection
Restart or open the manual switch after the unit has shut
，
down. Unit will not start immediately until 3
minutes later,because of the self-protect function of the compressor.
4.4 Dsfrosting function
In case of the unit requiring deicing during heating operation,TO prevent the heating efficiency from decreasing,
defrosting operation will turn on automatically (approx. 2~8 minutes) .
In the process of defrosting operation, the unit air supply motor will stop running.
4.5 Safety
a. Realize isolation between water and electricity. No electric shock problem, more safety.
b. No fuel tubes and storage, no potential danger from oil leakage, fire, explosion etc.
4.6 Autmatic Control:
Automatic start-up and shutdown, automatic defrosting by revising refrigerant cycle. Save you much extra
operation.
4.7 R410a gas, Environmental protection.
a. No discharge of poisonous gas.
b. No pollution to atmosphere and environment
4.8 All-the-weather Running.
Within the temperature range from -7 to 38
℃
, it will not be affected by night, cloudy sky,
rain even snow whether.
