Location
The chiller should be installed on solid horizontal surface
,
the
closer
to
the
laser
equipment
,
the

Avoid
voltage drops by using
properly grounded power outlets wired with 14 gauges
or larger diameter wire. If possible, be close
to the power distribution panel.
Using an extension cord may cause low line voltage problems
,
the
voltage
loss
should
be
with
10%
from
the
extension cord if this is inevitable.
The heating discharged by the fan is 1.4 times than the rated cooling capacity,
so the air
-
draft
and
air
discharge
side
shouldn
'
t be too close to wall. The air
discharge side should reserve at least 0.8m
,
the
installation
