Safety Information
Warning
Protect all flooring during the installation of Refrig-
eration Products. Additional support must be sup-
plied for countertops being placed over units when
installing units wider than 24”. While installing all
cabinets, ensure that the rear leveling legs are en-
gaged into the anti-tip brackets (supplied).
Take extreme caution when working with all tools
on or near stainless steel surfaces as they can
easily scratch. Always protect all surfaces to pre-
vent dents and scratches.
Refrigerant HFC-134a
All models covered in this service manual are
manufactured using refrigerant HFC-134a.
Potential Problems with HFC134a
HFC-134a compressors are manufactured with a
synthetic based ester oil charge. The hygroscop-
ic (water attraction) property of ester oil is many
times greater than that of the mineral oils previ-
ously used with CFC-12. High system moisture
causes the formation of acids and alcohol, which
can damage the compressor. Systems or compo-
nents of the refrigeration system should not be left
open to the atmosphere for more than (15) min-
utes at any time as humidity from the air will enter
the system and be absorbed by the oil. To assure
system dehydration, the system should be evacu-
ated to a level less than 100 microns and when
isolated, shall not exceed 500 microns for a mini-
mum of 10 minutes. Heating of the compressor
shell may be required to achieve proper vacuum
levels. Vacuum pump oil must never be allowed to
enter the refrigeration system.
No leak detection
dyes are authorized for use within any Resi-
dential Refrigeration Products. Subject use
will void complete system warranty and place
the burden on the service company for down-
line service issues.
Cleanliness of the system is extremely important.
The presence of residue (Chlorinated or greasy
residues, mineral oil, or impurities) can lead to
capillary tube restrictions, oil return problems and
compressor damage. Flux
must not
be used on
any brazed joints.
Residential Refrigeration cabinets are critically
charged systems. These systems do not have ac-
cess ports for servicing to the system. Provided
for access is a low side process tube, which will
require the service technician to attach a piercing
type “saddle valve”. Care must be taken to mini-
mize or avoid the loss of any refrigerant due to the
critical charge in the system. See I.D. plate for
charge amount or contact the factory for additional
information.
Anytime a Residential Refrigeration system is be-
ing serviced, it is recommended that the dryer be
changed using the exact same style and size with-
in the system to avoid possible charge problems
or contaminant issues. When removing a dryer
from an existing system never use heat. Cut the
inlet and outlet tubing to avoid pushing contami-
nants into the system from the dryer.
ELECTRICAL SHOCK HAZARD
Disconnect power or turn power disconnect switch
to “OFF” position before removing top grille. Failure
to do so can result in death or electrical shock.
ELECTRICAL SHOCK HAZARD
Plug into a grounded 3-prong outlet. If a 2-prong
wall receptacle is encountered, contact a qualified
electrician.
DO NOT remove ground prong.
Unit must be grounded at all times.
DO NOT use an adapter.
DO NOT use an extension cord.
Failure to follow these instructions can result in
death, fire, or electrical shock.
