Equipment Precautions
8.
Regularly clean the screen in the assembly at the chiller's inlet for Facility Water. To
clean, shut off the chiller, close off the supply of Facility Water to the chiller, and remove
the screen. Clean as necessary and reinstall. See Installation for further instructions.
9.
The compressor in this unit has been charged with a Polyolester lubricant. Polyolester
lubricants (POE) will quickly absorb moisture from the ambient surroundings. Since
moisture levels greater than 100 ppm will result in system corrosion and ultimate failure,
it is imperative that compressors, components, containers and the entire system be kept
sealed as much as possible. Lubricants will be packaged in specially designed, sealed
containers. After opening, all the lubricant in a container should be used at once since it
will readily absorb moisture if left exposed to ambient air. Work on systems and
compressors must be carried out with the open time as short as possible. Leaving the
system or compressor open during breaks or overnight MUST BE AVOIDED! Mobil EAL
ARCTIC 22 CC is the preferred Polyolester due to unique additives included in this
lubricant. ICI Emkarate RL 32S is an acceptable substitute if Mobil is not available.
10.
As received, the POE lubricant will be clear or straw colored. After use, it may acquire a
darker color. This merely reflects the activity of the lubricant's protective additive.
11.
Oil level must not fall below ¼ sight glass
12.
Do not operate the chiller at coolant temperatures above or below it was specified to
deliver.
13.
Do not run the chiller with cooling loads that exceed its factory rated cooling capacity.
14.
Do not operate damaged or leaking equipment.
15.
The chiller must not be transported unless properly protected. Original factory
packaging in good condition or equivalent is required. Request air-ride trucks if
transporting over the road.
16.
Modifying the chiller without express written consent from Lydall will void the warranty.
