MECHANICAL INSTALLATION
1. Select a location for installation.
The FC-3 needs to be perpendicular to the air flow
(air should flow past
ion emitters like a football through the goal posts). The FC-3 should be mounted so that the ion emitters are
exposed to airstream.
• The Ideal location on typical split systems is on the blower housing, the side opposite the blower motor.
The housing of the FC-3 should be so that the ion emitters extend slightly above the side of the blower
housing.
• The ideal location for ceiling cassette units is on the fan side of the protective screen/ grille
• The ideal location for mini split systems is after the filter and behind the coil, typically mounted to the
wall plate.
• The ideal location for a ducted module is on the intake side after the filter between the blower housings.
2. Secure the FC-3, if attaching to sheet metal use self-tapping screws if possible.
NOTE: Inspect the other side
of sheet metal to make sure screws will not damage refrigerant lines, wires, or other components.
When
attaching the FC-3 to a grille or screen nylon ties may be used.
3. The FC-3 ion emitters should not be touching any metal surface or wires. Move and secure any wires that
may come in contact with the ion emitters.
CAUTION:
THE NEEDLES MUST BE 2 INCHES AWAY FROM METAL SURFACES TO PREVENT ARCING
NOTE:
Use Temperature - Maximum Ambient temperature in which unit shall be used: 140 degree F/ 60°C
Electrical Installation
CAUTION:
MAKE SURE POWER IS DISCONNCTED TO THE HVAC EQUIPMENT BEFORE INSTALLATION
• Follow all local and national electrical and building codes.
• Verify voltage of circuit the FC-3 is being connected to.
• 24 VAC installation
1. Connect the red and black wires to a constant 24VAC source. NOTE: FC-3 units require 0.5 VAC to operate.
Verify capacity of HVAC system transformer prior to powering unit. A stand-alone transformer may be used.
2. Connect the orange wires to the Building Automation System wires or terminals (if present). If no BAS system
is present, then insulate ends of wires and secure wires where they will not be damaged.
