Figure FB- 6 – Wall Sleeve
Wall Sleeve
The cabinets wall sleeve is attached to
the wall by (4) four, #10 field provided
screws. This rigid design allows for ease
of separation from the cabinet assembly
during service or installation situations.
The wall sleeve is painted the same color
as the cabinet for aesthetic purposes.
Drain Pan
The unit drain pan is composed of
plastic, corrosive resistive material. The
pan is positively sloped to comply with
ASHRAE 62 for (IAQ) indoor air quality
conformity.
Access to the drain pan is provided
through the front chassis access panel.
The drain pan is removable for cleaning.
Cabinet Insulation
The cabinet insulation design meets UL
181 requirements. The air stream surface
of the insulation is fabricated of a non-
biodegradable source.
The insulation in the wet section of the
cabinet complies with ASHRAE standard
62 to accommodate (IAQ) indoor air
quality standards.
Refrigeration Piping
The unit’s copper tubing is created from
a 99% pure copper formation that
conforms to the American Society of
Testing (ASTM) B743 for seamless, light-
annealed processing.
The unit’s copper refrigeration system is
manufactured to be free from
contaminants and conditions such as
drilling fragments, dirt, or oil. This
reduces the possibility of these
contaminants damaging the compressor
motor.
Schrader Connections
The connections for the low and high
side of the refrigeration system are
located in the chassis portion of the unit
at the front of the refrigeration assembly.
Access to the schrader connections are
made through the refrigeration service
access panel.
Air-to-Refrigerant Coil
The air-to-refrigerant heat exchanger is
constructed of staggered copper tubes
with die-formed corrugated lanced
aluminum fins. The fins are then
mechanically bonded to the tubes
through expansion.
The maximum working pressure of the
coil is 450 psig. It is designed for
maximum capacity with an additional
benefit of physical unit size reduction.
Coil specifications for the GECA unit is
listed below.
Compressor
The unit’s design includes a rotary
compressor motor in dedicated voltages
and tonnage sizes to aid in voltage
variations along with noise reduction of
the unit.
As an added benefit, Trane double
isolates the compressor and the
mounting plate assembly in the unit to
reduce sound vibration during
compressor operation.
