If you are installing the ComPac®unit, first read Chapter 1 and scan the entire manual before

beginning the installation as described in Chapter 2. Chapter 1 contains general, descriptive

information and provides an overview which can speed up the installation process and simplify

troubleshooting.

If a malfunction occurs, follow this troubleshooting sequence:

1. Make sure you understand how the ComPac®unit works (Chapters 1 & 3).

2. Identify and correct installation errors (Chapter 2).

3. Refer to the troubleshooting information in Chapter 4.

If you are still unable to correct the problem, contact the Factory at 1-800-841-7854 for additional

assistance.

Please read the following “Important Safety Precautions” before beginning any work.

1. USE CARE when LIFTING or TRANSPORTING equipment.

2. TRANSPORT the UNIT UPRIGHT. Laying it down on its side may cause oil to leave the

compressor and breakage or damage to other components.

3. TURN ELECTRICAL POWER OFF AT THE breaker or fuse box BEFORE installing or

working on the equipment. LINE VOLTAGES ARE HAZARDOUS or LETHAL.

4. OBSERVE and COMPLY with ALL applicable PLUMBING, ELECTRICAL, and BUILD-

ING CODES & ordinances.

5. SERVICE may be performed ONLY by QUALIFIED and EXPERIENCED PERSONS.

* Wear safety goggles when servicing the refrigeration circuit

* Beware of hot surfaces on refrigerant circuit components

* Beware of sharp edges on sheet metal components

* Use care when recovering or adding refrigerant

6. Use COMMON SENSE - BE SAFETY-CONSCIOUS
