1.2 Serial nameplate
The serial nameplate is located on the inside of the unit, typically on the left liner side wall. The serial number will need to be
given when inquiring about the unit or ordering parts. DO NOT REMOVE THE SERIAL NAMEPLATE FROM THE UNIT. See Figure 1.1
below for a sample serial tag with manufacturing date code logic.
1.3 Before Servicing
Always disconnect power to any DCS product before attempting to service it. Always verify that power has been •
disconnected.
If the unit has been running, use caution around the condenser, compressor, and copper tubing. These areas may be very hot. •
Use caution around the 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 DCS 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 DCS product. •
Any refrigerant, whether CFC, HCFC, or HFC (R-12, R-22, or R-134a), must be recovered. Federal regulations prohibit the •
intentional venting or release of refrigerants during the service repair or disposal of an appliance.
