Leading Innovation in Scroll Semi-Hermetic Technology

Emerson realized an increasing need for a versatile, reliable, quiet, lightweight, serviceable compressor for the Cold Room market and set out to develop a solution for this need. In the development process, the company brought together 70 years of semi-hermetic compressor expertise and 25 years of leadership in scroll technology. What came out of this endeavor is the newly-designed Copeland Scroll Fusion compressor which combines Emerson’s revolutionary scroll technology along with the serviceability of a traditional semi-hermetic compressor.

Our Vision:

4 5

• Do not run the compressor with air. When operating

with air, the diesel effect may occur – i.e. the air sucked in may mix with oil and gas. Such a mixture could explode due to high temperature in the scroll discharge port and thereby destroy the compressor and cause injury or death.

• Open the discharge and suction shut-off valve before

starting the compressor. It is of vital importance that the discharge shut-off valve is fully opened before the compressor is started. If the discharge valve is closed or partly-closed, an unacceptable pressure accompanied by a proportionately high temperature will develop.

• All local safety regulations must be observed.

Electrical Shock

• Turn off electrical supply and power before servicing.

• Use this equipment only in a grounded system.

• Refer to the applicable system-wiring diagram as shown

in this manual.

Use Personal Safety Equipment

• The new compressor contains oil and dry air under a

pressure of 2.0 bar. While releasing pressure before installation, the oil drain plug may pop out under pressure and oil could spurt out.

• Safety gloves, protective clothing, safety boots and

protective eyewear should be worn where necessary.

Safety Information

CopelandTM brand products semi-hermetic compressors are manufactured according to international safety standards. Particular emphasis has been placed on the user’s safety. This user manual should be retained throughout the lifetime of the compressor.

Safety instructions must be followed by all users before compressor operation. Only quali ed and authorized personnel

are permitted to do installation, commissioning and repairing of this compressor. Electrical connections must be made

by quali ed electrical personnel.

Caution

• Make sure that the compressor is upright and there are

no collisions or tilting during transit.

• Use only refrigerants and oils approved by Emerson.

• Make sure that the supply power, voltage, frequency

and phase are exactly as per the speci cations on the

compressor nameplate.

• The dry air inside the compressor should be evacuated

before installation. The compressor comes charged with dry air at a pressure of 2.0 bar.

Do Not:

• Use the compressor to de-pressurize (to evacuate) a

refrigeration system.

• Start the compressor when it is under vacuum.

• Conduct a test without connecting the compressor to

a system.

• Start the compressor without a refrigerant charge.

• Operate a compressor beyond its approved application

envelope.

• Touch the compressor or pipes when the compressor

is running. High/low temperature may cause burns/ frostbite.

• Release refrigerant into the environment without using

appropriate refrigerant recovery unit and methods when removing refrigerant from the system.

• When operating the compressor or checking a

refrigeration system leakage, do not exceed operating pressures out of the application envelope.
