SECTION II MOVEMENT TO NEW WORKSITE
Dismantling for Movement
Short Distance. When moving the air conditioner to a new worksite which is a short distance away, perform the
Set air conditioning switch, located on remote control box assembly, to OFF position. Set the master
circuit breaker switch to OFF position.
Turn off main power supply. Disconnect power plug (P101) from input power receptacle (J101) at

Disconnect remote control wiring harness plug (P102) from electrical tray remote control receptacle (J102)
and from base of remote control box.
Remove the remote control box assembly from its mounting.
Close and secure the condenser air discharge door. Replace panel over electrical tray front panel. Make
sure all panels are secure.
Release the eight mounting bolts securing air conditioner to mount.
Using the lifting method described in paragraph 2-2c (1) or (2_, place the air conditioner on rolls or a skid.
Long Distance. When moving the air conditioner to a new worksite which is a long distance away, perform steps

Place a shipping plug on the high-pressure relief valve outlet port.
Close and secure the condenser air inlet door. Replace panel over electrical tray front panel. Make sure
all panels are secure.
Release the eight Mounting bolts securing air conditioner to mount.
Inspect the air conditioner to determine its condition. Correct deficiencies before placing equipment in
limited storage. Perform technical inspections on unboxed items in accordance with AR 743-505.
