Safety Precautions 2-1
2 Safety Precautions
GENERAL PRACTICES
1. ALWAYS WEAR GOGGLES OR SAFETY GLASSES. Refrigerant liquid and battery acid can permanently damage the
eyes (see First Aid).
2. Never close the compressor discharge service valve with the unit operating. Never operate the unit with the compressor
discharge valve closed.
3. Keep your hands clear of the fans and belts when the unit is operating. This should also be considered when opening and
closing the compressor service valves.
4. Make sure the gauge manifold hoses are in good condition. Never let them come in contact with a belt, fan motor pulley, or
any hot surface.
5. Never apply heat to a sealed refrigeration system or container.
6. Fluorocarbon refrigerants, in the presence of an open flame or electrical short, produce toxic gases that are severe respiratory
irritants capable of causing death.
7. Make sure all mounting bolts are tight and are of the correct length for their particular application.
8. Use extreme caution when drilling holes in the unit. The holes may weaken structural components, and holes drilled into
electrical wiring can cause fire or explosion.
9. Use caution when working around exposed coil fins. The fins can cause painful lacerations.
10. Use caution when working with a refrigerant or refrigeration system in any enclosed or confined area with a limited air supply
(for example, a truck body or garage). Refrigerant tends to displace air and can cause oxygen depletion which may result in
unconsciousness or death from suffocation.
11. Use caution and follow the manufacturer’s suggested practices when using ladders or scaffolds.
AUTO START/STOP CONTROLS
Units equipped with a CYCLE-SENTRY Automatic Start-Stop system may start automatically at any time when the On/Off
switch is in the “On” position and the CYCLE-SENTRY/Continuous Run switch is in the “CYCLE-SENTRY” position (or
CYCLE-SENTRY symbol appears in microprocessor display). Be sure to turn the On/Off switch “Off” before opening unit
service doors or inspecting or working on any part of the unit.
