4. Safety (Please follow the following content strictly)

Precautions in this section include:
Warning: a faulty operation that may cause death or serious injuries.
Caution: a faulty operation that may cause injuries or equipment failure. It may lead to even more
serious consequences according to severity.
Above two precautions are essential for safety, please keep it accessible to each chiller operator
after reading the manual, Be sure to hand over the Manual to the next person on duty.

4.1 Precautions during Installation

Make sure chiller is installed as per below requirements, otherwise rectifying measures must be
taken.
Warning:
A) Chiller installation must be carried out by qualified person.
Inappropriate installation might cause refrigerant leakage, electrical shock, fire accident etc.
B) Prevent refrigerant leakage
In case of refrigerant leakage, certain measure shall be taken to prevent suffocation caused
by high concentration refrigerant in air.
C) Strictly follow this manual during installation
Inappropriate installation might cause refrigerant leakage, electrical shock, fire accident etc.
D) Electrical cable shall be wired or connected by qualified and professional electrical engineers.
Please size the cable according to local electrical standard (refer to the Engineering Data,
EDUA14-04-2). Undersize cable might cause electrical shock or fire, etc.
E) Chiller foundation shall be capable to carry chiller weight
Chiller shall be installed in horizontal foundation and fixed by the anchor bolts. Chiller may
overturn if the foundation is not strong enough.
F) Check the unit alignment
This step operation must be done for Falling-film Chiller. As follows: Check the longitudinal
alignment by placing a level on the top center of the evaporator shell. Check the transverse
alignment by placing a level on the top of shell end sheets at each end of the unit. The unit
should be level within 6.5 mm longitudinally and 6.5mm transversely. When the unit is in place,
check that the chiller is level. If the unit is not level within the amount specified, lift it and place
as many shims as needed between the isolation pad and the end sheets. As shown in
