Carrier Transicold 69NT40-561-001 Operation And Service Manual page 16

Beware of unannounced starting of the evaporator and condenser fans. The unit may cycle the
fans and compressor unexpectedly as control requirements dictate.
Do not attempt to remove power plug(s) before turning OFF start-stop switch (ST), unit circuit
breaker(s) and external power source.
Make sure the power plugs are clean and dry before connecting to power receptacle.
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.
Make sure power to the unit is OFF and power plug disconnected before replacing the compressor.
Before disassembly of the compressor, be sure to relieve the internal pressure very carefully
by slightly loosening the couplings to break the seal.
Do not use a nitrogen cylinder without a pressure regulator.
Do not open the condenser fan grille before turning power OFF and disconnecting power plug.
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.
Wear rubber gloves and wash the solution from the skin immediately if accidental contact
occurs. Do not allow the solution to splash onto concrete.
Always turn OFF the unit circuit breakers (CB-1 & CB-2) and disconnect main power supply
before working on moving parts.
