5. Run Power and Control Wiring
M2 Series units are equipped with an
internal wiring chase, located along the
inside top of each module. Wire is provided
for power and control wiring inside the unit.
Wire from the unit to external controls and
power sources must be provided in the field.
A color-coded wiring diagram is laminated
and affixed to the inside of the control
compartment access door. M2 Series units
are equipped with a single point power
connection.
6. Final Sealing
It is very important to keep air from
infiltrating the unit cabinet. Seal all piping
penetrations with Armaflex, Permagum or
other suitable sealant. Also seal around drain
connections, electrical connections and all
other inlets where air may enter the cabinet.
This is especially important when the unit is
installed in an unconditioned area.
Refrigerant Piping
(See back of the manual for refrigerant
piping diagrams and connection sizes.)
Piping from the condensing unit to the air
handling unit is the responsibility of the
installing contractor.
The Split System Configurator or
Refrigerant Piping Calculator in
AAONEcat32 should be used to determine
acceptable refrigerant line sizes.
The pipe sizes must be selected to meet the
actual installation conditions and not simply
based on the connection sizes at the
evaporator or condensing unit.
Put straps in position,
hold in place and attach
with self-tapping sheet
metal screws.
Improper installation, adjustment,
alteration, service or maintenance
can cause property damage,
personal injury or loss of life.
Installation and service must be
performed by a trained, qualified
installer. A copy of this IOM should
be kept with the unit.
