G) Chiller shall be installed in indoor space
If chiller is installed in rainy or water dropping place, electric leakage \ shock might happen.
H) Use specified cable and ensure the connections are firm
Ensure the connections of cables are firm. Otherwise it may cause fire accident.
I) Constant pressure leakage test
In case of leakage when unit in constant pressure leakage testing, emptying lubricating oil (if
has) and nitrogen and then repair and test again. In case repair is conducted without
emptying lubricating oil, it might cause explosion.
Attention:
A) It is forbidden to install the chiller in flammable gas leakage condition
Fire accident or even explosion will happen when flammable gas concentration achieves
certain level.
B) Chiller shell shall be grounded
Ground cable shall avoid gas pipe\water pipe\lightning rod or telecom cable, wrong grounding
might cause shock.
C) Ground protector shall be equipped for the chiller
Leakage protector shall be installed as per local electrical standard. No leakage protector or
improper installation may cause electrical shock.
D) Each chiller shall be equipped with dedicated circuit breaker.
If only one main breaker is equipped for multiple chiller plant, it may cause shock or fire
accident.
E) Draining system shall be smooth at chiller installation location
A wrong draining system may cause draining failure which in turn may harm chiller electric
parts.
F) It is prohibited to lay the power cables between chillers, otherwise it may cause fire accident.
G) Chiller plant floor shall go through water proof treatment
Water proof floor will protect chiller from moisture.
