Operation

Shutdown

Place the SET/OFF/ON switch and the Main Power breaker to OFF.  If the unit will be shut down
for a long period, the fluid should be drained out of the unit and the lines blown dry with low
pressure air.  Always drain and dry the lines before storing or shipping the unit.  

Preventive Maintenance

All maintenance should be performed only by qualified technicians.  The frequency of
maintenance checks should be determined by the customer, as conditions vary from site to site. 

!

On a continuing basis the unit must be kept clean and dry inside and out.

!

Reservoir fluid should be kept at a satisfactory level.

!

A stainless steel mesh strainer attaches to the pump suction port near the bottom of the
reservoir.  It can easily be removed for cleaning.  First turn the pump off, then pull off the
strainer, rinse it clean, and push it back on.  To protect the pump, routinely inspect the
strainer to be sure it is clean and properly attached.  Hint:  If the strainer is coated with
debris, wrap it with a plastic sandwich bag before pulling it off to prevent most of the
debris from escaping into the reservoir.  Failure to clean a clogged strainer can restrict
flow, causing the FAULT light to illuminate.  Turn the chiller off for a few seconds after
correcting the condition to reset the alarm.  

!

All warning/alarm conditions should be addressed immediately.

!

The air filter in front of the condenser should be checked and cleaned regularly. 
Frequency will depend on the cleanliness of the area. 

Decommissioning

Decontamination procedures are not required or applicable as there are no hazardous materials
used within this unit.  The refrigerant used in this unit is environmentally friendly (a non-ozone
depleting HFC) and poses no hazard to the environment.  However, the refrigerant must be
recovered by a qualified refrigeration service technician in accordance with all applicable laws. 
When decommissioning, remove all fluids by opening all drains and placing the fluid in
appropriate containers.  After all flow has ceased, purge the lines with low pressure air. 

The unit is comprised of metals that may be recycled.  The significant metals which make up the
unit are as follows: 

‚

Cold-rolled steel

‚

Stainless steel

‚

Copper

There are no significant amounts of plastics or other materials incorporated into this unit. 
Recycle metals appropriately.
