Warning: please cut off the power before installation!!
3.2 Site requirements:
Ambient temperature and relative humidity (RH)
Our chiller suitable for install indoors, ambient temp. from 5℃ to 35℃, RH
less than 80%(No condensation) .
Location
The chiller should be installed on solid horizontal surface, the closer to the
laser equipment, the better cooling performance will achieve; keep the
chiller off the heating source at least 4inch (1.4meters), such as heating tube
and boiler.
Please install the chiller at place where drainage system is available in order to
keep the installation place clean in case of any leakage occurs, please don't
install the chiller in erosive gas, humidity, dusty places or indoors with high
temp..
Our chiller is equipped with wheel, which makes it easier for installation and
operation; the front wheel could be locked to secure the unit. 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 site should
ventilate well, the air-draft and air discharge volume of the site should be
a bit large than the chiller, or use air-condition with larger cooling
capacity than the heat discharge of the chiller to cool the installation site.
3.3 Power connection
Make sure the power wire rightly connected and current, frequency should be
match with the requirements marked on the label which was pasted on the back
of the chiller.
3.4 Connection accessories
Process pipeline
There are 2 inner thread interfaces for water pipe connection and water inlet
and outlet adapter is designed for connecting the accessories and working
pipeline.
In order to keep the working site clean and safe, please choose the right flexible
tube and accessories based on the liquid temperature and required temp.
