INTRODUCTION
This manual contains important instructions for installing, using, and servicing a MBGFP Fusion Plus case. A parts
list is included with this manual. Read all these documents carefully before installing or servicing your equipment.
STORE CONDITIONS
The MBGFP cases are designed to operate in the controlled environment of an air-conditioned store. The store
temperature should be at or below 75°F and a relative humidity of 55% or less. At higher temperature or humidity
conditions, the performance of these cases may be affected and the capacity diminished.
The MBGFP cases should not be positioned where it is directly exposed to rays of sun or near a direct source of
radiant heat or airflow. This will adversely affect the case and will result in poor performance.
If this case is to be located against a wall, there should be at least 6” space between the wall and the back of the
case. This space will allow for the circulation of air behind the case, which will prevent condensation on the exterior
surfaces.

PRE-INSTALLATION INSTRUCTIONS
INSPECTION FOR SHIPPING DAMAGE
You are responsible for filing all freight claims with the delivering truck line. Inspect all cartons and crates for damage
as soon as they arrive. If damage is noted to shipping crates or cartons or if a shortage is found, note this on the bill
of lading (all copies) prior to signing.
If damage is discovered when the cabinet is uncrated, immediately call the delivering truck line and follow up the call
with a written report indicating concealed damage to your shipment. Ask for an immediate inspection of your
concealed damage item. Crating material must be retained to show the inspector from the truck line.
INSTALLATION INSTRUCTIONS
GENERAL INSTRUCTIONS
1. Be sure the equipment is properly installed by competent service people.
2. Keep the equipment clean and sanitary so it will meet your local sanitation codes. Clean the cabinet with a mild
detergent and water, then rinse. Do not clean any plastic component of cabinet, such as door handles, with
stainless steel cleaners or any cleaning solution containing methyl acetate.
3. Rotate your stock so that older stock does not accumulate. This is especially important for ice scream. A "First-
In, First-Out" rotation practice will keep the products in good salable condition.
4. Do not place product in the case when it is soft or partially thawed. Also, product should not be put in the case
for at least 6 hours after it is started.
5. Stock cases as quickly as possible, exposing only small quantities to store temperatures for short periods of
time.
6. When replacing burned out light bars, be sure that the electrical power to the lighting circuit is turned off.
NOTICE TO STORE OWNERS / MANAGERS
Moisture or liquid round or under the c binet is potenti l slip/f ll h z rd for persons w lking by or
working in the gener l re of the c binet. Any c binet m lfunction or housekeeping problem th t cre tes
slip/f ll h z rd round or under the c binet should be corrected immedi tely.
If moisture or liquid is observed around or under the cabinet, an immediate investigation should be made by qualified
personnel to determine the source of the moisture or liquid. The investigation should determine if the cabinet is
malfunctioning or if there is a drainpipe leaking.
MECHANICAL
Remove front grille and check refrigeration lines to see that they are free (not touching each other or compressor).
Spin condenser fan blade to see that it is free. Insulate quick connects with pipe insulation to prevent condensation
and/or ice accumulating.
Remove cabinet from crate base and slide into location. Cabinet must be level from side to side and front to back for
correct draining of coil pan and for self-closing doors to operate correctly. Allow minimum of 4” between back of
cabinet and wall and between top of cabinet and ceiling for proper condensing unit air circulation.
To comply with Sanitation requirements the cabinet must be mounted on legs (6” high min.), casters, or the base
must be sealed to the floor with an N.S.F. listed silicone sealant. When sealing to the floor, leveling bolts can be uses
to assure the cabinet is level before applying silicone sealant.

ELECTRICAL
WARNING
Before servicing electric l components in the c se or the doors or door fr mes m ke sure ll
power to c se is off. Alw ys use qu lified technici n.
Check voltage and amps drawn on (TABLE 2) to determine proper line and fuse or circuit breaker size. Check power
supply for low voltage.
For example: If voltage reads “230” with no load, and it drops below “207” when the compressor tries to start, it is an
indication of too small supply wiring or too long to run.
It is recommended that a separate circuit be run for each cabinet to prevent another appliance blowing the fuse or
breaker, causing loss of product.
IMPORTANT
Models (3 door cabinet) are pre-wired internally with a 208-230V NEMA L14-20P plug and should only
be plugged into a NEMA L14-20P recepticle. See wiring diagrams for more details. The cabinet should
be grounded.
LEG / CASTER INSTALLATION
1. Screw legs / casters tightly into the rail
base mounting holes.

ELECTRONIC REFRIGERATION CONTROL
Display Lay-out
Compressor When power is first turned on the controller will go through the start-up. After the start-up delay the
compressor comes on. The LED indicator stays on while compressor relay is energized. Display will show actual box
temperature. Picture above is the display layout. The compressor will be cycled off when the actual box temperature
reaches its set point. The compressor indicator will be off.
F n The fans will run during cool mode, cycle during compressor off mode, and off when a defrost is initiated.
When in defrost mode the fans are off until the end of the defrost and the 2 minute drip time has passed. There is 2
minutes delay after a defrost before the fan comes on. If the Evaporator temperature is 35
o
F or below the controller
will override the fan delay. FAN LED indicator is on while fan relay is energized.
Defrost The control uses time defrost with 4 defrost per day. The defrost setting can be reset for special
applications. During defrost the display will show dEF and the defrost LED indicator will be on. The control begins
timing the defrost when power is turned on. Four defrosts per day means it will occur every 6 hours. Example: to
have defrost occur at 8am, 2pm, 8pm, and 2am then power up at one of these four times.
MANUAL DEFROST
Defrosting may also be induced manually by pressing the defrost button for 3 seconds. Once initiated, the unit will go
through a normal defrost and drip time pull down cycle.

ELECTRICAL CONNECTIONS
The controller is provided with a screw terminal block to connect cables with a cross section up to 2,5 mm
2
. Before
connecting cables make sure the power supply complies with the control’s requirements. Separate the probe cables
from the power supply cables, and the outputs and the power connections. Do not exceed the maximum current
allowed on each relay. In case of heavier loads use a suitable external relay or contactor.
PROBE CONNECTIONS
The probes shall be mounted with the bulb upwards to prevent damage due to casual liquid infiltration. It is
recommended to place the thermostat probe away from air streams to correctly measure the average room
temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is
formed, far from heaters or from the warmest place during defrost to prevent premature defrost termination.
