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.

CAUTION!

GROUND REQUIRED

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.

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.
