Operation of Specific Models
SCFF51OSWH MED Series
These frost-free all-freezers can be built-in or free-standing. They do not require defrosting
and have a digital thermostat, LED lighting and a lock. At the top of the unit is a cooling
system that uses a fan to provide cold air. For best operation, do not block the air flow with
contents.
FF6L, FF7L, FF28LWH, FF511L, FF521BL, FF590SSHH, FFAR2L, FFAR10, FFAR21L,
FFAR24L, SCR450L, SCR500BL, SCR600L, SCR610BL PLUS & MED Series;
SP6DS2D7, SP6DS7, SP6DSSTB7 MED Series only
These models are all-refrigerators (no freezer compartment) with automatic defrost. All
have cold plates on the rear wall, and the coldest spots in the refrigerator will be in the rear
and toward the bottom. All have interior fans to promote even cooling. In the rear bottom
above the step, there is a drain line to allow defrost water to exit the refrigerator. Keep this
drain line clear, or icing inside the refrigerator will occur. FF7, FF511L, FF521BL, and SCR
series models have lights that are not door-activated, and are controlled by a rocker switch
on the top right. The light generates a small amount of heat, so minimize the use of the light
for best operation and energy savings. FF6 models and FFAR10 models all have door-
activated lights. Smaller models and drawer models do not have interior lights.
NOTE: FF590, models with BI in the model number, and all drawer units are designed for
built-in operation and need very little clearance on the sides and above the units.
All
other models
FCL44, FS20L, FS21L, FS22L, FS24L, FS30L, FS60ML, FS407L, FS408BL, VT65ML
PLUS & MED Series
require at least 1 inch of airflow on the sides and above the units. All
models operate best when 2 inches is provided between the rear wall and the back of
the unit.
Model FCL44 is a chest freezer; all of the others are upright. These are manual defrost all-
freezers. No internal fans are present, and ice will build up along the cooling coils.
Periodically defrost the ice (recommended when the ice level reaches a thickness of 1/4 to
1/2 inch). NEVER USE A METAL INSTRUMENT as you can damage the cooling coils,
which will void your warranty and often cannot be repaired. To defrost, disconnect from the
power supply, empty the contents, provide a tray in the bottom to collect water, and use a
hairdryer or other source of warm air to melt the ice (or leave the door open and the power
off for 24 to 48 hours). For built-in (BI) models and clearance information, see NOTE
above.
CP35LL PLUS & MED Series; CT66 PLUS Series only
These models are cycle defrost refrigerator-freezers. The freezers are designed to operate
at 0°F (-18°C), suitable for medical or laboratory uses. These models have dual
evaporators to maintain separate temperatures in the freezer and refrigerator. Defrost the
freezer carefully, as directed above for manual defrost. The refrigerator section operates in
the normal range (35 to 45°F, or 2 to 7°C) and defrosts automatically. For built-in (BI)
models and clearance information, see NOTE above.
CM411L, CM421BL, S19LWH PLUS Series
These models are manual defrost refrigerator-freezers. The freezers in these models are
designed to operate at 25°F (-4°C) to keep ice frozen, and not for medication or products
needing colder temperatures. Defrost carefully, following directions above. The refrigerator
section will operate in the normal range (35 to 45°F, or 2 to 7°C) and is suitable for most
refrigerated products. For built-in (BI) models and clearance information, see NOTE above.
