INTRODUCTION

Thank you for purchasing a Horizontal Display case. This manual contains important instructions for installing, using and servicing the case. A parts list is included in with this manual. Read all these documents carefully before installing or servicing your equipment.

STORE CONDITIONS

The 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 case 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.

The case may be placed directly against the wall. This is due to the cabinet’s condenser cooling air entering and discharging through the front grille.

NOTICE

Read this manual before installing your case. 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 case.

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 case 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 have the serial number at hand and call or write Customer Service Department.

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 caset 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 sellable condition.

4. Do not place product in the case when it is soft or partially thawed. Also, product should not be put 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 case is a potential slip/fall hazard for persons walking by or

working in the general area of the case. Any 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 the case, an immediate investigation should be made by qualified personnel to determine the source of the moisture or liquid. The investigation should determine if the caset is malfunctioning or if there is a drainpipe leaking.

ELECTRICAL

WARNING

Before servicing electrical components in the case, make sure all power to case is off. Always use a qualified technician.

ELECTRICAL INFROMATION AND GROUNDING A separate circuit for each case is recommeded to avoid the possibility of other appliances on a circuit

to one of these cabinets overloading that circuit and causing malfunction. The electrical service should be grounded upon installation.
