INTRODUCTION

Thank you for purchasing this cabinet. This manual contains im portant instructions for installing, us ing and servicing an Open Air Merchandis er. 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 OAM 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 temper ature or humidity conditions, the performanc e of these cases may be affected and the capacity diminished. It is not uncom mon in a newly constructed store for the temperature and hum idity 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 OAM case should not be positioned where it is directly exposed to rays of the sun or near a direct source of radiant heat or air f low. No HVAC return or supply air ducts may be located near case openings. This will adversely affect the c ase air flow and will result in poor perform ance. Do not open windows or doors that will affect the c ase air flow. The maxim um 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 cas e. T he cabinet also requires a clearanc e 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.

A pipe loop acts as a trap is included with each case. It is important that each case has this installed. Consult the section of this manual for installing and piping the drain.

NOTICE

Read this manual before installing your cabinet. Keep the manual and refer to it before

doing any service on th e equipment. Failure to do so could result in personal injury or da m age 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 portion of this manual covering refrigeration and electrical c omponents contain technical ins truc tions intended only for persons qualified to perform refrigeration and electrical work.
