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.

The wiring for these models are basically the same. Power supplied to the electrical box. It then branches in three separate circuits. Compressor har ness, evaporator haness and lighting harness. The evaporator harness (fig 1) is not foamed in and can be replaced if necessary. It is routed from the electrical box up through a hole that enters just behind the evaporator coil (left-hand side).This bundle consists of two sensor leads and power supply to the defrost heater and ev aporator fan motor (when applicable).

The lighting harness originates from the secondary terminal board located just above the rear unit comparment.This comparment houses the lighting ballast, auxilliary outlet with the circuit breaker and light switch.

The lighting harness supplies power in two ways:

#1 circuit to shelf lights and rear perimeter heaters’ #2 citcuit to upper cavity light, front glass, front glass

perimeter and upper lighting channel heater. CAUTION: Make sure that the shelf light plugs or

receptacle covers are completely inserted into the light socket receptacles.This prevents electrical arcing and or possible equipment damage.

#3. Shelf light receptacles

#4. Rear perimeter heater raceway

Circuit #3

This circuit enters the foamed-in area behind the shelf lighting. The receptacle travels up to the upper light-

ing receptacle #5 and power supply to glass and perimeter heater #6 and #7.

Access these connections by removing the top from the cabinet. Then pr y up the galvanized subtop cover and lift out insulation. This will expose the wiring bundle (view shown with insulation removed).
