SAFETY

CAUTION

ALL MAINTENANCE AND ADJUSTMENTS MUST BE

DONE BY A QUALIFIED SERVICE TECHNICIAN.

Note:

For Water-cooled freezers connected to glycol cooling systems,

freezers must be switched to city water prior to trouble-shooting freezers.

IMPORTANT:

Some refrigerants are hazardous to the earth's atmosphere. To

protect our environment, use a refrigerant recovery/recycling unit

when removing refrigerant from the system.

This safety alert symbol identifies important personal safety

messages in this manual. When you see this symbol, be alert

to the possibility of personal injury.

DO NOT

attempt to continue

until the safety precautions are thoroughly understood.

CAUTION

TO AVOID ELECTRICAL SHOCK OR CONTACT

WITH MOVING PARTS, MAKE SURE ALL

SWITCHES ARE IN THE “OFF” POSITION

AND THAT THE MAIN POWER SUPPLY IS

DISCONNECTED. SOME FREEZERS HAVE MORE

THAN ONE DISCONNECT SWITCH.
