Pre-Installation
Considerations
The compressor, condenser, and fan
motor access panels are secured with
quick acting fasteners. Fast thread
screws secure access panels for
economizer coils, evaporator coils
expansion valves, water valves, and left
fan bearing. Access to other components
requires removal of semipermanent
panels secured with sheet metal screws.
During operation, sight glasses are
viewable through the portholes on the
unit's left upper panel.
WARNING
!
Disconnect electrical power
source before servicing the unit.
Failure to do so may result in
injury or death from electrical
