V. PRODUCT FEATURES (cont’d)
V. e - CONDENSATE EVAPORATOR:
During the “On-Demand Defrost” cycle or the
“Off Cycle” of the compressor, the evaporator
coil will defrost. The condensate from the
evaporator coil flows from the top of the unit
down a drain in the back to a condensate pan.
Vapor escapes through the back grill. The
vapor can sometimes be visible and should be
considered a normal operating condition.
Proper attention should be given to defrosting
your unit. Every “event” or time the unit is used
with the door open, the coil will build-up ice.
This reduces the effectiveness of the overall
operation of the unit.
V. f - TRAY SLIDES:
Ten (10) pairs of removable tray slides are
provided standard at 4-1/2" spacing. Each tray
slide can accommodate one (1) 18" x 26" pan /
tray.
V. g - WRAP-AROUND PERIMETER BUMPERS:
As the Air-Curtain refrigerator was designed
to be mobile, a full extension perimeter rubber
bumper guard is included to protect the unit
as well as surrounding walls and doors during
movement.
VI. ELECTRONIC CONTROLLER
VI. a - CONTROL OVERVIEW:
The Traulsen Air Curtain models are supplied
standard with an easy to use microprocessor
control. It features several important user
functions, greatly enhancing the overall utility
of the cabinet. The Traulsen RAC-37 is the only
two-stage (two temperature settings) Air
Curtain currently available on the market.
This feature allows the unit to be placed into
service at either “Standard Temp” or lower
“Colder Temp” settings.
VI. b - CONTROL FEATURE - ON/OFF:
This button has two uses: The first is to turn
the unit ON and OFF. The second allows for the
temperature display to be changed to indicate
either degrees (F) Fahrenheit or degrees (C)
Celsius. To change between temperature
scales; While unit is OFF, press and hold
the ON/OFF button for five (5) seconds. The
refrigerator will start and then the display will
switch from “dgF” to “dgC”. Repeat this step
to change the temperature scale again.
VI. c - CONTROL FEATURE - “ON” LIGHT:
When illuminated the ON light indicates that
the power is ON.
VI. d - CONTROL FEATURE - “CYCLE” LIGHT:
When illuminated the CYCLE light indicates
that the cabinet is cooling down to the desired
SET-POINT temperature. When cooling
-4-
elements are activated, this light will remain
illuminated until the cabinet has reached the
SET-POINT temperature, and will go OFF at
that time.
VI. e - TEMP RECALL:
This feature displays either the actual internal
cabinet air temperature (default), or the desired
“Set-Point” temperature (alternate).
ACTUAL: The factory default setting shows
the actual (A) internal cabinet temperature and
acts as a digital thermometer. A momentary
touch of the TEMP RECALL button will recall
the original temperature setting. The display
will then automatically return the displaying
the actual internal cabinet temperature.
SET-POINT: To display the set-point (S)
temperature instead of the actual internal
cabinet temperature. The display will indicate
the set-point temperature until such time that
the temperature is approximately 5°F +/-
away from the set-point setting for more
than 5 minutes, at which time the display will
indicate actual temperature. Once the internal
temperature return to set-point, the controller
resumes to show set-point values.
To switch from one of these display functions
to the other, press and hold the TEMP RECALL
button for five (5) seconds. The display will
flash either “S” (SET) or “A” (ACTUAL) to
indicate which mode is active. To switch
back again, repeat this step holding the
TEMP RECALL button for five (5) seconds.
VII. OPEN DOOR:
During open door operation a sensor knows the
door is open, display will show “OPEn”. An internal
countdown timer will start, factory default will
allow unit open door operation for a maximum of
90 minutes. During the 90-minute open door
operation the cooling system will remain on.
If door is open longer than 90 minutes an open door
alarm will be activated. Display will flash “OPEn”
and beep three times every ten seconds.
To terminate the open door alarm, the door must
be closed and remain closed for 30 minutes.
(See page i).
DISPLAY UNDER NORMAL OPERATION:
• Unit will display internal and/or set point
temperature (see pg. 4, VI)
• A door sensor knows the door is open. When
operating with door open the display will show
“OPEn”.
• After a 90-minute open door operation, unit will
have a “5 min” (minute) countdown display prior
to terminating operation. (see page i).
• Unit will perform a defrost operation, after a door
open secession, the display will show “Def”. This
ensures optimum open door performance during
the next door open secession. Door must remain
closed until defrost cycle is complete,
approximately 30 minutes.
