grated economizer provides simultaneous operation
between mechanical cooling and economizer operation.
Independent blade design insures proper control and less
than 1% leak rate. Includes hood and mesh bird screen filter
integrated into the hood, dry bulb sensor and relief damper.
Separate field accessories of single/dual enthalpy kits are
also available.
• Economizer for Horizontal Applications
(S1-2EE04708624, S1-2EE04708724) - Modulating inte-
grated economizer provides simultaneous operation
between the mechanical cooling and economizer operation.
Independent blade design insures proper control and less
than 1% leak rate. Includes hood and mesh bird screen filter
integrated into hood, dry bulb sensor and relief damper. Sep-
arate field accessories of single enthalpy and dual enthalpy
are available.
• Single/Dual Enthalpy Sensor (S1-2EC04700624) - Sensor
replaces dry bulb sensor standard in economizer kit. Pro-
vides improved economizer operation by sensing the dry
bulb temperature from outdoors plus the enthalpy content of
the outdoor air.
• CO2 Sensor Kit (S1-2AQ04700824) - Sensor kit detects
CO2 levels automatically and overrides the economizer
when CO2 levels rise above the preset limits.
• Outdoor Temperature Sensor Kit

openings on the base unit. Transition is from rectangle to 12"
round for the 1AK0110 kit and from rectangle to 14" round for
the 1AK0111 kit.
• Rectangle to Round (Downflow) Adapter
(S1-1AK0108, S1-1AK0109) - Kit includes one supply and
one return air rectangle to round duct adapter. Adapters are
preformed and designed to fit into current downflow duct
openings on the roof curb. Transition is from rectangle to 16"
round for the 1AK0108 kit and from rectangle to 18" round for
the 1AK0109 kit.
• Roof Curbs (S1-1RC0503, S1-1RC0501) - NRCA approved
curbs provide proper fit to base unit for rooftop installations.
Curbs are designed to be assembled through hinge pins in
each corner. Kit also provides seal strip to assure an air tight
seal. These are 8 inch high roof curbs.
• Roof Curbs (S1-1RC0504, S1-1RC0502) - NRCA approved
curbs provide proper fit to base unit for rooftop installations.
Curbs are designed for assembly through hinge pins in each
corner. Kit also provides seal strip to assure air tight seal.

• Manual Outdoor Damper (S1-1FA0502, S1-1FA0501) -
Provides 0% through 50% outdoor air capability (field adjust-
able). Designed for duct mounted side supply/return applica-
tions and unit mounted down supply/return applications.
Includes hood and screen assembly.
• Transformer Kit (S1-2EC06700124) -
Kit provides neces-
sary ha
rdware
to provide single phase models from factory
furnished 40 VA transformer capability to 75 VA transformer
capability. (Required on installations with economizer or
motorized damper).
• Base Rail Hole Cover Kit (S1-1HC0101) - Kit provides nec-
essary hardware to close off openings in base rails to block
off openings, i.e. prevent animal entrance.
• Loss of Charge Sensor (S1-2LC00024) - Kit provides Loss
of Charge sensor and wiring to provide safe shutdown of
compressor.
• Single Point Wiring Accessory Kits for 6HK Electric Heat
Applications (S1-SPWK*) - Kits provide field option for con-
necting electrical power supplies to the field installed 6HK
kits to allow single point connections for single phase electric
heat applications with the exception of 25kW kits.
• Transition Curb Kits (S1-1TC01*) - Adapter kits to allow
field use of pre-existing installed roof curbs to match PHE4
footprint to Affinity roof curbs, Carrier, Trane, or Goodman
curb footprints. Curb adapters are optional for current gener-
ation Carrier replacements but are recommended for previ-
ous generation applications. Refer to the PCE4 price pages
for more details.
• Wall Thermostat - The units are designed to operate with
standard, 24-volt electronic non power stealing and electro-
mechanical thermostats. All units can operate with single
stage heat/single stage cool thermostats - with or without the
economizer.
