INTRODUCTION

Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing,
using and servicing a Master-Bilt MPM/QMPM series open air case. Read all these documents carefully
before installing or servicing your equipment. This manual should be left in the care of the store owner or
manager.

STORE CONDITIONS / LOCATION

The Master-Bilt MPM/QMPM 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 MPM/QMPM should not be positioned where it is directly exposed to rays of the sun or near a
direct source of radiant heat or air flow. No HVAC return or supply air ducts may be located near case
openings. This will adversely affect the case air flow and will result in poor performance. Do not open windows
or doors that will affect the case air flow. The maximum air velocity near the case air return is 50 FPM. If this
case is to be located against a wall there should be at least a 6” space between the wall and the back of the
case. The cabinet also requires a clearance of 10” at the top. This space will allow for the circulation of air
behind the case.

These cases should always be loaded properly. This unit will operate differently when loaded or unloaded.
Consult the section of this manual that specifies loading procedures on page 6.

A P-trap is included with each case. It is important that each case has a P-trap installed. Check drain tubing to
insure that it is traped and routed into the condensate pan.

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.
