WARNING

Make sure that the unit circuit breaker(s) (CB-1 & CB-2) and the START-STOP switch (ST) are in the “O” (OFF) position before connecting to any electrical power source.

WARNING

Never use air for leak testing. It has been determined that pressurized, mixtures of refrigerant and air can undergo combustion when exposed to an ignition source.

WARNING

Make sure power to the unit is OFF and power plug disconnected before replacing the compressor.

WARNING

Before disassembly of the compressor make sure to relieve the internal pressure very carefully by slightly loosening the couplings to break the seal.

WARNING

Oakite No. 32 is an acid. Be sure that the acid is slowly added to the water. DO NOT PUT WATER INTO THE ACID - this will cause spattering and excessive heat.

WARNING

Wear rubber gloves and wash the solution from the skin immediately if accidental contact occurs. Do not allow the solution to splash onto concrete.

WARNING

Always turn OFF the unit circuit breakers (CB-1 & CB-2) and disconnect main power supply before working on moving parts.

WARNING

Make sure power to the unit is OFF and power plug disconnected before removing capacitor(s).

WARNING

With power OFF discharge the capacitor before disconnecting the circuit wiring.

WARNING

Do not use a nitrogen cylinder without a pressure regulator. Do not use oxygen in or near a refrigera- tion system as an explosion may occur.

WARNING

Do not open the condenser fan grille before turning power OFF and disconnecting power plug.

WARNING

The Unit Power Plug Must Be Disconnected To Remove Power From Circuit Breaker Cb1

CAUTION

Do not remove wire harnesses from controller modules unless you are grounded to the unit frame with a static safe wrist strap.

CAUTION

Unplug all controller module wire harness connectors before performing arc welding on any part of the container.

CAUTION

When condenser water flow is below 11 lpm (3 gpm) or when water-cooled operation is not in use, the CFS switch MUST be set to position ”1” or the unit will not operate properly.

CAUTION

Pre-trip inspection should not be performed with critical temperature cargoes in the container.
