Application Considerations — RDS 800C
Unit Coils
Electric Heat
Unit cooling coils are available in either direct expansion
or chilled water type and can be located in the Heat/Cool
sections, position D and I, and in the Draw-through Cooling/Supply Air Fan section, position F.
l
Unit chilled water coils are available with or without a factory installed control valve when provided without a combination heating coil.
l
l
Unit heating coils are available in either steam or hot
water type and can be located in the Heat/Cool sections,
positions D and I, or the Heat sections, positions E and G.
l
Unit heating coils are available with or without a factory
installed control valve in the Heat sections, positions E
and G.
l
Gas Heat
l
Contractor coils are available in direct expansion, chilled
water, steam and hot water type and are located in the
Heat/Cool sections, positions D and I.
Contractor coils are available with or without factory
installed face and bypass dampers less actuator.
l
A gas heating furnace is located in the Blow-through
Heat section, position G only.
Final Filters

Application Considerations — RDS 802C
Unit Coils
l
Electric Heat
Unit cooling coils are available in either direct expansion
or chilled water type and can be located in the Heat/Cool
sections, position D and I.
l
Unit chilled water coils are available with or without a factory installed control valve when provided without a combination heating coil.
l
Unit heating coils are available in either steam or hot
water type and can be located in the Heat/Cool sections,
positions D and I, or the Heat sections, positions E and G.
l
Unit heating coils are available with or without a factory
installed control valve in the Heat sections, positions E
and G.
Contractor Coils
l
Contractor coils are available in direct expansion, chilled
water, steam and hot water type and are located in the
Heat/Cool sections, positions D and I.
l
Contractor coils are available with or without factory
installed face and bypass dampers less actuator.
l
Electric heating coils are located in the Blow-through
Gas Heat
l
A gas heating furnace is located in the Blow-through
Final Filters
l
Final filters are not available with a drain pan only or any
option with a cooling coil located in the Blow-through
Heat/Cool section, position I.
Blank Access Compartment
l
a discharge plenum in position K with bottom or side discharge only.
General
l
When any section is located in position H (Blank Access
section), I (Blow-through Heat/Cool section), or J (Final
Filter section), a heating or blank section must be placed
in position G to provide proper airflow diffusion for the
sections that follow the supply air fan.

Unit Considerations — RAH047C
Splitting Units
Gas Heat
All units with DWDI supply fans may be split at the
Supply Air Fan section outlet.
l
l
Cooling Coils
Cooling Coils are available in either direct expansion or
chilled water type and can be located in the Heat/Cool
sections.
Chilled water cooling coils are available with or without
factory installed three-way modulating control valve as
well as face and bypass dampers and actuator.
Factory wired control of cooling coils is limited to one
cooling coil section per unit.
l
l
l
Heating Media - Steam/Hot Water
Heating coils are available in either steam or hot water
type and can be located in either the Heat/Cool sections
or the Heat sections.
Heating coils are available with or without factory
installed face and bypass dampers and actuator in the
Heat/Cool sections. Factory installed control valves are
not available on heating coils in the Heat/Cool sections.
Heating coils are available with or without a factory
installed control valve in the Heat sections. Factory
installed face and bypass dampers are not available on
heating coils in the Heat sections.
l
l
l
Electric heating coils can be located in the Blow-through
Heat section, position G only on units with a DWDI
supply fan
l
Final Filters
l
If final filters are installed, a Discharge Plenum section is
required in position K.
l
Final filters are not available on units with a SWSI supply
fan.
l
Final filters are not available on units with a blow-through
cooling coil in the Heat/Cool section, position I.
Blank access compartment
l
a discharge plenum in position K with bottom or side
discharge only.
l
The blank access compartment is not available on units
with a SWSI supply fan
General
l
Electric Heat
A gas heating furnace can be located in the Blowthrough Heat section, position G only on units with a
DWDI supply fan. Factory wired control of cooling coils is
limited to one heating section per unit.
When any selection is located in position H (Blank
access section), I (Blow-through Heat/Cool Section), or J
(Final Filter Section) a heating or blank section must be
placed in position G to provide proper airflow diffusion for
the sections that follow the supply fan

Unit Considerations — RAH077C
Splitting Units
Electric Heat
l
All units with DWDI supply fans may be split at the
Supply Air Fan section outlet.
l
Units exceeding 52 feet in length may need to be split at
the Supply Air Fan section outlet for shipping purposes.
l
Gas Heat
l
Cooling Coils
l
Cooling Coils are available in either direct expansion or
chilled water type and can be located in the Heat/Cool
sections.
l
Chilled water cooling coils are available with or without
factory installed three-way modulating control valve as
well as face and bypass dampers and actuator.
l
Factory wired control of cooling coils is limited to one
cooling coil section per unit.
Heating Media - Steam/Hot Water
A gas heating furnace can be located in the Blowthrough Heat section, position G only on units with a
DWDI supply fan. Factory wired control of cooling coils is
limited to one heating section per unit.
Final Filters
l
l
l
If final filters are installed, a Discharge Plenum section is
required in position K.
Final filters are not available on units with a SWSI supply
fan.
Final filters are not available on units with a blow-through
cooling coil in the Heat/Cool section, position I.
Blank access compartment
l
Heating coils are available in either steam or hot water
type and can be located in either the Heat/Cool sections
or the Heat sections.
l
l
Heating coils are available with or without factory
installed face and bypass dampers and actuator in the
Heat/Cool sections. Factory installed control valves are
not available on heating coils in the Heat/Cool sections.
l
Heating coils are available with or without a factory
installed control valve in the Heat sections. Factory
installed face and bypass dampers are not available on
heating coils in the Heat sections.
l
Electric heating coils can be located in the Blow-through
Heat section, position G only on units with a DWDI
supply fan
a discharge plenum in position K with bottom or side
discharge only.
The blank access compartment is not available on units
with a SWSI supply fan
General
l
When any selection is located in position H (Blank
access section), I (Blow-through Heat/Cool Section), or J
(Final Filter Section) a heating or blank section must be
placed in position G to provide proper airflow diffusion for
the sections that follow the supply fan
