INTRODUCTION

Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using, and
servicing a Master-Bilt BLG/TLG 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 BLG/TLG 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 BLG/TLG 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.

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

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.

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 (BLG) with an N.S.F. listed silicone sealant.

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.

Check voltage and amps drawn on (Page 17-20) to determine proper line and fuse or circuit breaker size. Check
power supply for low voltage. 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 (2 and 3 door low temp) 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 on

page 19-21. The cabinet should be grounded.

LEG AND CONDENSATE PAN INSTALLATION FOR TOP MOUNT CABINETS ONLY

1. Screw legs into existing crate mounting holes.

2. Before moving cabinet into place, remove the
condensate pan from the top unit compartment.

3.

Using the two screws supplied with the pan, attach
the pan to the back of the cabinet at the two holes
near the bottom of the plastic drain line. Be sure
pan is NOT located directly under cabinet. When
the pan is attached, feeds drain line into the open
hole in screen and clamp the heater conduit to the
back of the cabinet. Due to this condensate pan,
this case must be a minimum of 6” from the wall.

4. If cabinet must be located next to wall, the pan can
be located under the cabinet. When this is done,
steam will accumulate on the bottom of the cabinet
if there is not adequate ventilation, and rusting of
the bottom of the cabinet

will occur.
