INTRODUCTION

Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using, and
servicing a Master-Bilt BMG/TMG case. A parts list is included with this manual. Read all these documents carefully
before installing or servicing your equipment.

STORE CONDITIONS

The Master-Bilt BMG/TMG 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 Master-Bilt BMG/TMG 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 4” 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.

NOTICE

Read this manual before installing your cabinet. Keep the manual and refer to it before

doing any service on the equipment. Failure to do so could result in personal injury or damage to the cabinet.

DANGER

Improper or faulty hook-up of electrical components on the refrigeration units can result in severe injury or
death.

All electrical wiring hook-ups must be done in accordance with all applicable local, regional or national
standards.

NOTICE

Installation and service of the refrigeration and electrical components of the cabinet must be performed by a
refrigeration mechanic and/or a licensed electrician.

The portions of this manual covering refrigeration and electrical components contain technical instructions intended
only for persons qualified to perform refrigeration and electrical work.
This manual cannot cover every installation, use or service situation. If you need additional information, call or write us:

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.

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 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 fluorescent tubes, be sure that the electrical power to the lighting circuit is turned off.

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 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.

The compressor is hermetic, it is internally spring mounted and ready to run.

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.) or casters or the base must
be sealed to the floor (BMG) with an N.S.F. listed silicone sealant.

Hang provided NSF Listed thermometer at front of top shelf unless cabinet provided with electronic control.
