flexibility. A MERV 4, 1 in. [2.54 cm] is standard with an optional
2 in. [5.1 cm] MERV 13 for LEED certification points and high
efficiency filtration.
Electrical Box
Unit controls feature quick
connect wiring harnesses
for easy servicing. Separate
knockouts for low voltage and
two sides of the electrical corner
post for easy access to the
control box. Large transformer
(75VA with ABC with reheat and
FX10, 50VA with ABC without
reheat) assures adequate controls power for accessories.
Water Connections
Flush mount FPT water
connection fittings allow
one wrench leak-free
connections and do not
require a backup wrench.
Horizontal Hanger Kits
Each horizontal unit includes
a hanger kit to meet seismic
specification requirements
while still allowing filter access.
Drain Pan
All condensate connections are PVC glue for economical corrosion
free connections. Bacteria resistant composite drain pan is sloped to
promote complete drainage and will never rust or corrode. Complete
drainage helps to inhibit bacterial or microbial growth. Vertical units
feature an internally trapped condensate line using clear PVC hose
for easy inspection and reduced installation cost. Optional factory
installed stainless steel drain pans are also available.
Compressors
High efficiency R-410A rotary or scroll
compressors are used on every model.
Rotary or scrolls provide both the highest
efficiency available and great reliability.
Single speed scroll models are available in
commercial voltages.
Compressor Dual Isolation Mounting
Double isolated compressor mounting utilizing eight durometer
selected rubber grommets. This isolation greatly reduces the
primary noise frequency range of 100-300 Hz.
Air Handler Insulation
Washable air handler insulation
surface provides cleanability to
further enhance IAQ.
Thermostatic Expansion Valve
All RG Series models utilize a balanced port
bidirectional thermostatic expansion valve (TXV)
for refrigerant metering. This allows precise
refrigerant flow in a wide range of entering water
variation (20 to 120°F [-7 to 49°C]) found in
geothermal systems. The TXV is located in the
compressor compartment for easy access.
