Before Servicing
• Always disconnect power to any Viking product
before attempting to service it. Always verify
that power has been disconnected.
• If the unit has been running, use caution around
condenser and copper tubing. These areas may
be very hot.
• Use caution around condenser fins and
baseplate edges. These areas are sharp.
• Refrigerant is under high pressure. Always
evacuate any system before attempting to work
on it.
• Reasonable care and safe work methods should
be practiced when working on any Viking
product. Never work with energized electrical
equipment in wet or damp areas.
• Use an appropriate work area and location
when performing repairs. You will find that it is
easier to repair undercounter units if they are
set on a raised platform or workbench.
• Always wear protective safety glasses and
gloves when working on any Viking product.
• Any refrigerant, whether CFC, HCFC, or HFC
(R-12, R-22, or R-134a), must be recovered.
Federal regulationsprohibit intentional venting
or release of refrigerants during service repair
or disposal of an appliance.
After Servicing
After servicing the unit, whether at a site or service
center, check the following:
• MAKE CERTAIN THERE ARE NO LEAKS IN
DRAIN OR WATER LINES. Check water line,
water valve, drain valve, and drain tubing for
leaks.
• Make certain ice machine functions properly
by observing ice production and ice harvest
cycles. Check for hollow ice slabs or ice slabs
that will not release.
• Make certain bin thermostat will turn unit off.
The best way to check this is to let ice maker
bin fill with ice. However, if time is restricted
then use several ice cubes and place them on
bin thermostat’s capillary tube sleeve located
on side of ice bin. The unit should shut down
within a few minutes. After removing ice, unit
should start at least five minutes later.
