Routine Service Checks

Inspecting the Coolant

Inspect the coolant level at regular intervals, when the equipment is in use.

Normally check once or twice a week, more often if it is used continuously or

under high ambient temperatures. The coolant level should remain at the

upper gauge mark on the back panel, whether the unit is running or not. For

test measurement and addition of liquid if required, see “Coolant” on page 9.
Inspecting the External Surface

The radiator surface, particularly on the inside, should be checked periodi-

cally for possible collection of dust and lint. A heavy lint coating on the inside

surface of the radiator can impair the cooling efficiency of the unit. Follow the

instructions below for cleaning. See “Cleaning”.

Cleaning

The most important cleaning task is to remove accumulations of dust, lint,

and grime that could interfere with proper air circulation and therefore effi-

cient heat transfer. The heat exchanger surfaces, particularly on the inside,

should be checked periodically for possible collection of dust and lint.

Equipment Needed:
z

Lint-free cleaning cloth

Mild detergent

Cleaning the Instrument Housing and Panels

1. Remove loose dirt and grime, gently, using a soft clean cloth dampened

with a warm solution of mild detergent and water.

Note:

A vacuum can be used to clean the radiators if necessary.

2. Remove the 26 screws from the top panel to gain access to the radiators.
3. Clean off dust and lint, if any, with a radiator brush or stiff bristle brush.
4. Check under the ribs of the air intake grille (at the side) for dust collec-

tion. If there is a buildup, remove the grille and clean under the ribs.

5. Replace top panel and screws.

Note:

Heavy coatings of lint on any surfaces of the heat exchanger

unit can impair the efficiency of the Moduload unit. Keep them clean.

Cleaning the Connector and Outside Surface

Note:

Use a soft, clean cloth dampened with mild detergent.

Wipe dust and dirt from the outside surface of the unit

Note: z

This should be performed at regular intervals.

Check the condition of the RF coaxial connector.

Clean the RF input connector, If needed, use a self-drying contact
cleaner that leaves no residue.
