1 Yearly Condenser Tubes Inspection

DANGER

Wait 20 minutes after disconnecting power from unit before opening any compressor access covers. The DC link capacitors store enough energy to cause electrocution.

Key:Performed by qualified service personnel

1)Condenser Tubes: Inspect the condenser tubes annually for fouling and clean if required. The standard waterboxes should be removed with care due to their weight. One method for handling standard water boxes follows (only qualified service personnel should perform these tasks):

• After draining water, remove all but two head bolts at roughly 10 and 2 o’clock.

• Loosen the remaining two bolts to enable the head to be separated from the tube sheet sufficiently for a clevis pin or hook to be inserted into an open bolt hole at the top of the head.

• Attach a hoist to the pin or hook, lift the head to remove weight from the two remaining bolts, remove the bolts, and carefully remove the head.

• Do not try to install a machine thread eyebolt into the head vent fitting, which has pipe threads.

• Reverse this procedure to mount the head, using a new gasket.

Chiller Strainer Cleaning

DANGER: Wait 20 minutes after disconnecting power from unit before opening any compressor access covers. The DC link capacitors store enough energy to cause electrocution.

A common cause of service calls and equipment malfunction is dirt. This can be prevented with normal maintenance.

The system components most subject to dirt are:

Strainers: Remove and clean strainers in the chilled water system

Strainers: Remove and clean strainers in the condenser water system
