1.6 Optional Controls & Packages
Protective Coating Packages
Coated Coils:
Either the condenser or evaporator coil can be coated. For harsh conditions, e.g.,
power plants, paper mills or sites were the unit will be exposed to salt water, the coils should be
coated.
Note:
Cooling capacity may be reduced by up to 5% on units with coated coils.
Coastal Environmental Package:
This package includes:
• Corrosion resistant fasteners,
• Sealed or partially sealed condenser fan motor,
• Coating applied to all exposed internal copper and metal in the in the condenser section, and
• A protective coating on the condenser coil.
All Coat Package:
Includes the same features as the Coastal Environmental Package and adds a
coating on the evaporator coil and on all exterior and interior components and sheet metal. (
Note:
the insulated internal sheet metal and the internal control box are not coated).
Dirty Filter Indicator
A diaphragm type of indicator measures the air pressure on either side of the filter and when the pressure
drops below the set point, a red LED is illuminated. The set point is adjustable.
Cabinet Color and Material
ICE air conditioners are available in two cabinet colors -the standard gray and beige. The standard
cabinet’s sides, top and front panels are constructed of 16 gauge painted steel. Contact your sales
representative for color chips, custom colors and 316 stainless steel cabinets.
Fresh Air Damper
Allows introduction of outside air into the building to provide positive pressurization. Field installed
on either the left or right hand side of the unit. See Appendix A for installation instructions.

Crankcase Heater
Crankcase Heater Recommended for use for units installed in cold climates.
Dual Compressors With Lead/Lag Operation
Freeze Sensor On Indoor Coil
Prevents frost on the indoor coil caused by a loss of air flow or restrictive duct work.
Filter Access From Return Air Grille
Factory or field installed filter bracket allows changing and access to the filters from the return air grille.
See model ID, special option code “I”.
Reverse Air Flow Configuration
Location of Supply and Return Air Openings are reversed.
1.7 Electrical Operation
The compressor and condenser fan are energized with a contactor controlled by a 24 VAC pilot signal.
Some compressors incorporate an internal PTC crankcase heater that functions as long as primary power
is available. The heater drives liquid refrigerant from the crankcase and prevents loss of lubrication
caused by oil dilution. Power must be applied to the unit for 24 hours before starting the compressor.
The condenser (outside fan) motor is energized by the same contactor.
The indoor evaporator fan motor is controlled by the fan purge on the electronic control board.
