INTRODUCTION

Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing,
using and servicing a Master-Bilt TAF ERC2 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 TAF ERC2 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 TAF ERC2 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 (see page 7). 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 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.
This manual cannot cover every installation, use or service situation. If you need additional information, call or

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

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.

Check that all service valves (2) are open. Cut compressor hold-down strap and remove. The springs are
secured for shipping by either tightening bolts or shipping strap. Remove the strap or loosen the hold-down
bolts so that the compressor floats freely. Check all refrigeration lines and electrical conduit for rubbing or
chaffing, paying particular
attention to area where lines enter the cabinet.

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 with an N.S.F. listed silicone sealant.

To comply with UL requirements the cabinet must have a minimum clearance of 4” at the top, 6” at the
rear and 0” at each side.

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.
