INTRODUCTION
Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing,
using and servicing a Master-Bilt SMB/WMB case. A parts list is included in with this manual. Read all these
documents carefully before installing or servicing your equipment.
STORE CONDITIONS
The Master-Bilt SMB/WMB 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.
The Master-Bilt SMB/WMB should not be positioned where it is directly exposed to rays of sun or near a direct
source of radiant heat or air flow. 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 and allow the refrigeration system to discharge air properly.
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 of 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.

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.
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 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 drain pipe leaking.
