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. Wipe up all spills, clean with water and a mild detergent, then rinse with clean water.

3. Rotate your stock so that older stock does not accumulate. This is especially important for ice
   cream. A “First-In, First-Out” rotation practice will keep the products in good sellable condition.

4. Do not place product in a BEL 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 flourescent bulb/LED light bar, be sure that the electrical power to the lighting circuit is turned off.

To comply with N.S.F. requirements, this cabinet must be sealed to the floor with NSF listed silicone sealant. Before moving cabinet into place, route cabinet plumbing with P-trap to store drain line or install optional condensate pan.

STORE CONDITIONS
The Master-Bilt BEL/BEM 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. It is not uncommon in a newly constructed store for the temperature and humidity to be above design conditions. These excessive conditions may produce sweating in the case until the store is operational and the ambient environment is more desirable.

LOCATION
The Master-Bilt BEL/BEM should not be positioned where it is directly exposed to rays of the sun or near a direct source of radiant heat or air flow.
Cabinet should not be built into an enclosed area. If this case is to be located against a wall there should be at least a 4” space between the wall and the back of the case, with 4” open space at top and 1” on both ends. This space will allow for the circulation of air behind the case which will prevent condensation on the exterior surfaces.
Make sure that the floor that will support this equipment is of adequate strength to prohibit sagging. After confirming the dimensions of case with the blueprint measure off and mark on the floor the exact location of the cases for the entire lineup. Snap chalk lines where the base skids of the case are to be located as shown in Figure 1. LEVELING
It is very important that this equipment be perfectly level. This will allow for proper and complete drainage of the evaporator coil and for proper case alignment. A perfectly level area is generally not available where the equipment is to be installed. Mark the location of all case joining points front and back. Use a transit to locate the highest point on the chalk lines. This point will be a reference point for determining shim-pack heights. Using the reference point, mark the difference directly on the floor to each joining point front and back. Shim each joining point to equal the reference point as required. Tape all shims in place. If the installation is an entire lineup install the case that will be positioned at the highest point first. Check that the equipment in the lineup is level as the installation proceeds.

JOINING MULTIPLE SECTIONS
Remove the case from its shipping skid. Set the first case into its desired position with required shims in preparation for joining it with its adjacent case.

Bolt the included sex bolts through the door frame to secure the door frames together as shown in Figure 3. Make sure that the gasket strips on each frame are intact and free of damage to ensure a proper seal between the two frame sections. Repeat the above process for all other cases in the lineup.

Cases joined together require an application of butyl caulking to provide an air-tight seal. Apply a generous bead to all exposed foam edges at the end of the case. Inspect the bead to make sure there are no gaps and that there is sufficient material to provide a complete seal. The cases are now ready to be joined together. Remove the second case from its shipping skid and move it into position against the end of the first case. Properly level the second case with the appropriate shims.
Bolt the cases together through the five holes that are provided in the end frame as shown in Figure 2. Tighten the bolts until all seams are fully closed. Do not over tighten.

INSTALLING THE KICKPLATE
Install the kickplate behind the bumper and in front of the kickplate bracket. Secure the kickplate first by attaching it to the top pre-drilled holes of the kickplate brackets using the supplied #10×3/4” sheet metal screws. Then install the bumper by placing the top in the retaining rail and placing sheet metal screws through the bottom pre-drilled holes of the bracket. Refer to Figure 4 for the placement of the kickplate.

INSTALLING JOINING TRIM
To install the kickplate joiner, first make sure that the bumper is removed. Attach the kickplate retainer with the (2) #10×3/4” self-drilling sheet metal screws provided with the kit as shown in Figure 5. Rettach the bumper onto the bumper retaining rail and attach with screws as shown in Figure 4.

Figure 4 – Kickplate installation

REMOVING AND REPLACING THE ENDS
The ends of a BEL/BEM are bolted to the ends of the cabinet itself. There are five attachment points on each end as shown in Figure 6. Each attachment point uses a 5/16” hex head bolt and washer. The bolts are fed through the holes in the end frames and into threaded retainers in the end panel. Care should be taken not overtighten the bolts as this could lead to stripping of the threaded retainer. Consult the factory if it is necessary to remove or replace the end of a BEL/BEM.

PLUMBING
The BEL/BEM is equipped with a condensate drain kit to be installed. The drain kit connects to the bottom middle of the cabinet. This drain kit includes a (2) 90 Elbows, a Threaded Fitting, a Barbed Fitting, and a Trap. Connect supplied flexible hose to the barbed fitting and to the drain or condensate pump, whichever is applicable. It is very important that this trap be installed as it will result in diminished performance of the case without it. The kickplate will need to be removed to see the piping.

1. Always install drains in accordance with local codes.
2. Use largest possible size pipe for drains, one inch minimum is recommended.
3. Provide as much downhill slope as possible.
4. Prevent drains from freezing. Do not install drains in contact with uninsulated suction lines.

NOTICE TO STORE OWNERS / MANAGERS
Moisture or liquid around or under the cabinet is a potential slip/fall hazard for persons walking by or working in the general area of the cabinet. Any cabinet malfunction or housekeeping problem that creates a slip/fall hazard around or under the cabinet should be corrected immediately.
If moisture or liquid is observed around or under a Master-Bilt 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 drain pipe leaking.

ELECTRICAL
WARNING
Before servicing electrical components in the case or the doors or door frames make sure all power to case is off. Always use a qualified technician.
It is very important that full voltage and overcurrent protection requirements for condensing units, defrost heaters, fans, door and frame heaters, etc. be provided at installation. Wire sizing must be adequate to maintain full voltage under amperage loads specified in the charts are in this manual.

REFRIGERANT PIPING
The piping connections for a BEL/BEM are piped out of the cabinet to the customer’s specifications. These lines have been capped and should be cut with a tubing cutter so as not to introduce copper shavings into the system. Only clean, dry, sealed refrigeration grade AC hard copper tubing should be used. Be sure to install a suction line oil trap or ‘P-trap for both the BEL/BEM’s. It is recommended that all brazed joints be made with silver alloy-type solders. For roof top condensing units, an inverted P-trap must be installed in the suction line where the refrigeration lines exit onto the roof. For vertical line runs of more than 20 ft., a riser trap must be installed at the approximate center of the riser. The condensing unit should be located as closely as possible to the cabinet. Keep the refrigeration lines as short as possible and use as few fittings as practicable, being especially careful not to “kink” the lines. Keep the layouts as simple as possible and properly support the piping to absorb vibration and the normal expansion and contraction caused by temperature changes. All suction lines should be well- insulated to minimize heat absorption and control condensate which could form on the suction line. If tubular insulation is used, the ends, joints, and any other open areas (including slits necessary to fit the tubing over installed piping) should be sealed with insulation glue. A minimum amount of flux should be used as needed and a small amount of dry nitrogen should be fed into the tubing during brazing to minimize formation of scale and oxidation inside the tubing. Leak check all joints with an electronic leak detector or halide torch. If leaks are found relieve the pressure and make repairs as necessary and recheck. Thoroughly caulk or foam all refrigeration line entry holes. All openings for wiring should be sealed with NSF listed sealant to prevent air leaks and unwanted condensation.

REFRIGERATION SYSTEM EVACUATING AND CHARGING

1. Blow out all refrigerant lines with dry nitrogen or carbon dioxide to eliminate the possibility of dirt, scale, etc. remaining inside.
2. Connect all lines and leak test all connections.
3. Connect a good high vacuum pump to both the low and high side evacuation valves.
4. Operate the pump until a vacuum of 1500 microns (0.06 inches of mercury) absolute pressure is obtained. At this point, the vacuum should be broken by the introduction of refrigerant into the system, through a drier, until the pressure is brought up to zero pounds gauge. Repeat this procedure two more times. During the final evacuation, a vacuum of 500 microns (0.02 inches of mercury) absolute pressure should be obtained. After this vacuum is reached, the system can be fully charged with refrigerant.
