Handling the Cabinet
The refrigeration system of the cabinet is designed to
operate with the cabinet located on a flat surface.
Avoid tilting the cabinet more than 30° to any side. If
the cabinet must be tilted on an angle for handling or
moving purposes, allow it to sit in an upright position
20 to 30 minutes prior to plugging it in and starting the
cooling of the storage compartment.
GENERAL INFORMATION
2 MODULAR MERCHANDISER
Removing the Skid
Remove the four (4) bolts securing the cabinet to four
(4) angle brackets attached to the skid. Remove the
skid bolts and angle brackets.Carefully slide the cabinet off the skid onto the floor.
Locating the Cabinet
This model is a display cabinet and should be positioned to expose the illuminated displays to customers
in the store and provide a clear space behind for the
person serving.
Select a location where you are sure that the cabinet
won’t be exposed to heat sources such as sun through
a window, store heating or cooling ducts, exhausts
from other cabinets, etc. Make sure there is adequate
space on the serving side for loading cabinet and serving efficiently.
DO NOT DRILL HOLES IN THE CABINET WALLS.
THIS WILL VOID THE W ARRANTY
a.The cabinet must be installed on a sturdy and solid,
level floor.
b. The cabinet should be installed in a protected, dr y,
and well-ventilated area, away from any heat source.
Leveling the Cabinet
Level the cabinet using a spirit level on top. Level front
to back and side to side to assure a quiet operation
and satisfactory door and drain operation. Doors are
self-closing (sliding door models only) when cabinet is
level. Shim under the cabinet base as necessary to
assure a level cabinet. To meet NSF requirements,
these cabinets must be sealed to the floor with an NSF
listed or FDA approved sealant.
Setting up the Cabinet
Cabinets are shipped with the adjustable shelf mounting brackets in place. Shelving is also supplied with
the cabinet.
Shipping material (cardboard, paper, plastic, ties,
etc.) should be removed from shelving and the
product area.
CAUTION: Make sure that the shelf light plugs or
receptacle covers are completely inserted into the light
socket receptacles.This prev ents electrical arcing and/
or possible equipment damage.

Grounding Instructions
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazards.The appliance should be plugged directly into a proper ly grounded three prong receptacle.
Where a two-prong wall receptacle is encountered, it must be replaced with a properly grounded threeprong receptacle in accordance with the National Electrical Code and local codes and ordinances.The
work must be done by a licensed electrician (cabinet should be on a dedicated circuit unto itself.Refer
to serial data for correct circuit ampacity).

GENERAL INFORMATION-cont.
Power Supply Switch
NOTE:When ser vicing or cleaning supply power must
be turned off.The power supply switch is located at the
rear of each cabinet behind the lower rear grill. The
switch is incorporated into the electrical box assembly.
Light Switch-Auxiliary Outlet
The light switch is located at the rear of each cabinet
(when applicable) just above the unit compartment
opening on the right hand side.
The auxiliary outlet is provided to power an external
sign scale (when applicable).
These cabinets utilize a microprocessor control to
manage both cavity temperature and defrost functions.
Cabinet OperationRefrigeration Mode
Upon setting the cabinet in it’s final location, turn
power supply on. The cabinet display should be indicating the cabinet temperature.There is a three minute
time delay sequence built in each time the supply
power is lost (compressor circuit). Evaporator fan
starts and lights come on (medium temp models).
Three minutes later the compressor starts. On low
temp models the evaporator fan delays until the evaporator coil reaches 28°F.
The display located on the lower front panel has several functions,
Display cabinet temperature
Change cavity set point temperature
NOTE: ON MED TEMP CABINETS DO
NOT SET BELOW 33°F.
Display service interface. Only qualified service personnel should activate this function.
Defrost Mode
This is on a demand basis as needed on both medium
and low temperature models.Defrost can be manually
activated through the display if needed.See below.
High Temp Thermodisc Open 140°F
Close 90°F
Notable points
1. This system utilizes a 3 minute off cycle timer to pre-
vent short cycles.
2. When the system initiates a defrost, the setpoint will
flash on and off until the defrost is terminated and the
cavity reaches the setpoint. At this time the cavity tem-
perature will be displayed as normal.
Changing Setpoint
Note: Use a paper clip to access the
function keys.
1. Pressing the top right button(i.e. up key) on the display unit will raise the set point one degree
Fahrenheit. Holding the button down will scroll the
adjustment.
2. Pressing the lower right button(i.e.down key) on the
display unit will lower the set point one degree
Fahrenheit.
The Service Interface and
the Service Menu
(Refer to Pulse Service Manual 51-2484-00 for complete
service information.)
The service menu offers the service technician direct
control of the components of the system. This allows the
technician to force the system into a defrost state or the
refrigeration state. This feature also allows the technician to toggle the state in order to analyze separate components of the system (e.g., start kit, compressor,
heaters, etc.).
1. To access the service menu, press and hold the
service key for 2 seconds. The system will enter the
service menu and c0 will alternately flash with evaporator temperature. Code versions 1.5 and earlier do not
display evaporator temperature. This is the top of the
service menu. To exit the service menu, press the service key again at any time.
2. The service menu offers five functions:
Refrigeration state, Defrost state, code revision level
indication, the option to blank the display (code version
1.6 and later), and Celsius or Fahrenheit operation
(code version 1.6 and later).While in the service menu,

the down key serves to scroll the menu and the up key
serves as a toggle to activate and deactivate the function state.
A. To access the functions simply press the down key
to scroll through the menu until the desired function
is reached.The Refr igeration state is the first function and is denoted by an alternating display of c0
and the evaporator temperature. The Defrost state
is the second function and is denoted by a display
of d0.The third function is a passive state and only
indicates which version of code is running. This
function alternately flashes cc and the code version
01 - 99. The fourth function allows the user the
option to blank the display and is denoted by S0.
The fifth and last option allows the user to select
between Fahrenheit and Celsius operation and is
denoted by a C or a F. Continuing to scroll will bring
the user to the top of the menu again where c0 will
be displayed.
B.To activate a function state, simply press the down
key to scroll the menu until the desired function is
reached. Now press the up key. At this point the
chosen function state is toggled from inactive to
active.
C. To force a defrost: First press and hold the
service button to enter the service menu. Then
press the down key until d0 is displayed. Next
press the up key. The heater is now energized
and d1 is displayed.
D. To activate the refrigeration state: (i.e., this turns on
the compressor, condenser fans, and evaporator
fans) First enter the service menu. Press the top
right button.c0 will change to c1.Use this function to
check refrigerant charge and pressures, evaporator
fans, compressor and start components and etc.
E. To deactivate the function state, press the up key
again (i.e., this button toggles the state from active
to inactive and vice versa).
NOTES:a. When an attempt is made to scroll the
menu while a function state is active, the
active function state will automatically
deactivate.This is to prevent the service
technician from simultaneously activating
the Refrigeration state and the Defrost
state. Only one function may be active at
any given time.
b. If no operation is performed within 45
minutes while in the service menu, the
system will automatically exit the service
menu and return to normal refrigeration.
c. If the Defrost state is activated and left
unattended, the service menu will terminate the defrost as normal on evaporator
temperature; otherwise, the defrost will
terminate in 45 minutes. Upon defrost
termination the system will automatically
exit the service menu.
d. When the system exits the service menu,
the compressor will not start for
3 minutes.
e. The off cycle timer is not incorporated in
the service menu so the service technician has direct control of components.
