GUIDE SPECIFICATIONS — 548F036-120 (cont)
12. Power Exhaust Accessory for EconoMi$erIV or
EconoMi$er2:
Power exhaust shall be used in conjunction with
EconoMi$erIV or EconoMi$er2 to provide system
exhaust of up to 100% of return air (vertical only).
The power exhaust is a field-installed accessory
(separate vertical and horizontal design).
NOTE: Horizontal power exhaust is intended to
mount in return ductwork.
As the outdoor-air damper opens and closes, both
propeller fans are energized and deenergized
through the EconoMi$erIV controller. The set point is
factory set at 100% of outdoor-air, and is adjustable
0 to 100% to meet specific job requirements. Avail-
able in 208/230-1-60 v or 460-3-60 v. An LED light
on the controller indicates when the power exhaust
is operating.
For the EconoMi$er2, the power exhaust shall be
controlled by the third party controls.
13. Outdoor Air Enthalpy Sensor (EconoMi$erIV or
EconoMi$er2):
The outdoor air enthalpy sensor shall be used with
the EconoMi$erIV or EconoMi$er2 device to provide
single enthalpy control. When used in conjunction
with a return air enthalpy sensor, the unit will provide
differential enthalpy control. The sensor allows the
unit to determine if outside air is suitable for free
cooling.
14. Return Air Enthalpy Sensor (EconoMi$erIV or
EconoMi$er2):
The return air enthalpy sensor shall be used with the
EconoMi$erIV or EconoMi$er2 device. When used
in conjunction with an outdoor air enthalpy sensor,
the EconoMi$erIV or EconoMi$er2 device will pro-
vide differential enthalpy control.
15. Return Air Temperature Sensor (EconoMi$erIV or
EconoMi$er2):
The return air temperature sensor shall be used with
the EconoMi$erIV or EconoMi$er2 device. When
used in conjunction with the standard outdoor air
temperature sensor, the EconoMi$erIV or
EconoMi$er2 device will provide differential temper-
ature control.
16. Outdoor Air/Return Air Temperature Sensor (adjust-
able) (EconoMi$er2):
Optional sensor uses the third party control to control
outdoor air damper and compressor operation.
17. Indoor Air Quality (CO
2
) Sensor:
a. Sensor shall have the ability to provide demand
ventilation indoor air quality (IAQ) control through
the EconoMi$er2 with an IAQ sensor.
b. The IAQ sensor shall be available in duct mount,
wall mount, and wall mount with LED display. The
set point shall have adjustment capability.
c. Requires EconoMi$er2 third party control options.
18. Outdoor Coil Hail Guard Assembly:
Hail guard shall protect against damage from hail
and flying debris.
19. Indoor Air Quality (CO
2
) Room Sensor
(EconoMi$erIV):
Sensor shall have the ability to provide demand ven-
tilation control through the EconoMi$erIV. The IAQ
sensor shall be wall mounted with an LED display in
parts per million. The set point shall have adjustment
capability.
20. Return Air CO
2
Sensor (EconoMi$erIV):
Sensor shall have the ability to provide demand ven-
tilation control through the EconoMi$erIV. The IAQ
sensor shall be duct mounted. The set point shall
have adjustment capability.
21. Alternate Motors and/or Drives (036-060,090,120):
Alternate motors and drives shall be factory-installed
to provide additional performance range.
22. High-Static Motor(s) and Drive(s):
High-static motor(s) and drive(s) shall be factory-
installed to provide an additional performance range.
23. Outdoor Coil Grille:
The grille protects the outdoor coil from damage by
large objects without increasing unit clearances.
24. Compressor Cycle Delay:
Unit shall be prevented from restarting for a mini-
mum of 5 min. after shutdown.
25. Louvered Hail Guard:
The hail guard shall protect the entire outdoor coil
surface from direct or indirect (from adjacent sur-
faces) hail damage. Hail guard shall have a pressure
drop of 2%.
26. Fan/Filter Status Switch:
Switch shall provide status of evaporator fan (ON/
OFF) or filter (CLEAN/DIRTY). Status shall be dis-
played over communication bus when used with
direct digital controls or with an indicator light at the
thermostat.
27. Unit-Mounted Disconnect Switch:
Switch shall be factory-installed. Internally mounted,
NEC and UL approved non-fused switch provides
unit power shutoff. Switch shall be accessible from
outside the unit.
28. Convenience Outlet:
Outlet shall be factory-installed and internally
mounted with easily accessible 115-v female recep-
tacle. Outlet shall include 15 amp GFI receptacle
with independent fuse protection. Voltage required to
operate convenience outlet shall be provided by a
factory-installed step-down transformer. Outlet shall
be accessible from outside the unit.
NOTE: Convenience outlet shall be designed for
short duration electrical maintenance loads and is
not designed for long term electrical supply.
29. Emergency Heat Package:
When mechanical heating is locked out, auxiliary
heat shall be activated when necessary.
30. Ultra-Violet Germicidal Lamps:
Ultra-violet germicidal lamps are designed to elimi-
nate odor causing mold and fungus that may
develop in the wet area of the indoor section of the
unit. The high output, low temperature germicidal
lamps are field installed in the indoor section of the
unit, aimed at the indoor coil and condensate pan.
The short wavelength ultra-violet light inhibits and
kills mold, fungus and microbial growth. The lamps
have an output rating at 45 F in 400 fpm airflow
of 120 microwatts/cm
2
at 1 meter.
