Cabinet — Powder
coat painted. Matching discharge plenums and decorative supply and
return air grilles are available for use when units are to be installed
within conditioned space.
Motor—Inherently protected motors are mounted inside of insulated cabinet to
reduce motor noise. A choice of motor horsepowers and drive combinations
are available to allow you to meet specified CFM at various static
pressures up to 2" [.498 kPa] external static pressure.
Low Profile — Allows
for horizontal installation in most standard drop ceiling applications,
and the movement of units through most standard doorways for addition
or replacement work.
Thermal Expansion Valves — Standard all models.
Filters — One
inch [25 mm] throwaway filters are standard, but filter racks are
designed to accept either one inch [25 mm] or two inch [51 mm] filters.
Evaporator Coil —Two
circuit, interlaced row split coils are constructed with copper tubes
and aluminum fins mechanically bonded to the tubes for maximum heat
transfer capabilities. All coil assemblies are leak tested up to 450
PSIG [3100 kPa] internal pressure prior to installation into units.
Refrigerant Connections — Field
piping connections are made through a fixed post between two side
access panels on either side of the unit. Allows flexibility to meet
most field conditions as well as full accessibility after the
installation is complete.
Units may be used with two straight cool condensing units or single
circuit manifolded in the field using the copper fittings shipped with
each unit. The RHGL Air Handler has not been tested, rated or certified
to operate with dual remote heat pumps.
Drain Pan —The
galvanized steel drain pan is designed to trap condensate in either
vertical or horizontal installations. Condensate drain connections are
located on both sides of the unit allowing complete flexibility to meet
most field conditions.
Service Access —Two removable panels on top and each side of the unit are easily removed for access to motors, blowers, sheaves, and filters.
Horizontal or Vertical — All
models are designed for either application and can be installed in
either position as supplied from the factory. (See page 22)
Testing — All units are run tested at the factory prior to shipment.
Units are shipped with a holding charge of nitrogen.
