CyberChiller Series Installation, Operation & Maintenance Manual

CAUTION

All personnel working on or near equipment should be familiar with hazards associated with electrical maintenance. Safety placards/stick- ers have been placed on the unit to call attention to all personal and equipment damage hazard areas.

CAUTION

Ensure the unit is properly phased. Improper phasing can cause severe damage to the com- pressor.

WARNING

Refrigerant (R-22 or R-407C) is used with this equipment. Death or serious injury may result if personnel fail to observe proper safety precau- tions. Great care must be exercised to prevent contact of liquid refrigerant or refrigerant gas, discharged under pressure, with any part of the body. The extremely low temperature resulting from the rapid expansion of liquid refrigerant or pressurized gas can cause sudden and irreversible tissue damage.

As a minimum, all personnel should wear thermal protective gloves and face-shield/goggles when working with refrigerant. Application of excessive heat to any component will cause extreme pressure and may result in a rupture.

Exposure of refrigerant to an open flame or a very hot surface will cause a chemical reaction that will form carbonyl chloride (hydrochloric/hy- drofluoric acid); a highly poisonous and corrosive gas commonly referred to as PHOSGENE. In its natural state, refrigerant is a colorless, odorless vapor with no toxic characteristics. It is heavier than air and will disperse rapidly in a well-ventilated area. In an unventilated area, it presents a danger as a suffocant.

Always refer to the manufacturer's MSDS provided with the unit.

WARNING

Avoid skin contact or inhaling fumes from any acid formed by burn out of oil and refrigerant. Wear gas mask if area is not thoroughly venti- lated. Wear protective goggles or glasses to protect eyes. Wear rubber gloves to protect hands. Use care to avoid spilling compressor burnout sludge. If sludge is spilled , clean area thoroughly.

WARNING

When performing soldering or desoldering op- erations, make certain the refrigeration system is fully recovered and purged and dry nitrogen is flowing through the system at the rate of not less than 1-2 CFM (.03 - .06 M³/minute).

CAUTION

Certain maintenance or cleaning procedures may call for the use and handling of chemicals, solvents, or cleansers. Always refer to the manufacturer's Material Safety Data Sheet (MSDS) prior to using these materials. Clean parts in a well-ventilated area. Avoid inhalation of solvent fumes and prolonged exposure of skin to cleaning solvents. Wash exposed skin thoroughly after contact with solvents.

CAUTION

Do not use cleaning solvents near open flame or excessive heat. Wear eye protection when blowing solvent from parts. The pressure-wash should not exceed 30 psig. Solvent solutions should be disposed of in accordance with local and state regulatory statutes.

CAUTION

Units must be kept in its normal installed posi- tion. If the unit is not kept level and vertical, damage to the unit's compressors will result.
