Installation Location
WARNING: MAKE SURE POWER IS DISCONNECTED TO THE HVAC EQUIPMENT BEFORE INSTALLATION
AVERTISSEMENT: ASSUREZ-VOUS QUE L’ALIMENTATION EST DÉCONNECTÉE DE L’ÉQUIPEMENT CVC
AVANT L’INSTALLATION
GPS recommends mounting the GPS-FC24-AC after the ltration system and after the coil(s) section(s) in the HVAC
system. In ductless mini-split ceiling cassette applications, it is suggested to mount the unit to the fan inlet. The
emitter brushes should be no closer than two inches from any wiring or metal objects.
NOTE: Use Temperature - Maximum Ambient temperature in which unit shall be used: 140 degree F/ 60°C

Mechanical Installation
1. Ensure power to the HVAC equipment and the circuit the GPS-FC24-AC will be connected to has been turned
o.
2. Find an appropriate location. Verify the carbon ber emitters have a 2” clearance from wires or other metal
objects.
3. Mount the magnets to the GPS-FC24-AC using included hardware. See FIGURE 1.
4. When mounting in a ceiling cassette use zip ties to secure GPS-FC24-AC to fan inlet screen or grid. NOTE: if
mounting in a ceiling cassette that has a self cleaning lter, the unit must be mounted behind the screen and
self cleaning system, but before the fan inlet.
5. Install the GPS-FC24-AC so that airow is passing by both emitters at the same time (like a football through
goalposts). Make sure the unit is positioned so it obstructs as little airow as possible.

Wiring
1. Conrm the power is o prior to wiring. Follow all local and national electrical and building codes.
2. GPS recommends the GPS-FC24 be powered constantly and NOT switched with the system or blower.
3. The GPS-FC24-AC will self-adjust to voltages from 24VAC to 240VAC. Output and performance will not be
eected by the choice of input voltage. Connect the power wires as follows:
Black 24 - 240VAC
White Neutral or L2
Green Ground
Brown Dry Contacts/BAS Alarm
4. Wire in BAS terminals (optional) The GPS-FC24-AC is equipped with a set of dry contacts that are normally
open and close when the GPS-FC24-AC is on and has no faults. The contacts are rated up to 250VAC and 1A.
Operation
CAUTION! NEVER TOUCH BRUSHES WHILE OPERATING, SHOCK MAY OCCUR
MISE EN GARDE! NE JAMAIS TOUCHER AUX BROSSES PENDANT LE FONCTIONNEMENT, UN CHOC PEUT SE
PRODUIRE
Once powered and the inline switch is in the on position, the unit initiates an internal check of all systems. If the
auto cleaning wiper blade is not in the “home” position, it will move to the home position in series with the airow.
Cleaning Cycle
The GPS-FC24-AC comes with a preset cleaning cycle designed to clean the brushes once per day. The cleaning
process may be activated by pushing the clean button located on the side of the unit. To change the cycle frequen-
cy, press the cleaning cycle button once. While cleaning is in progress press and hold the cleaning cycle button for 5
seconds. The LED will start ashing. Pressing the cleaning cycle button again will begin to cycle through the settings for
number of days between cleaning cycles. The speed of ashes increases with number of days (slowest = 1 day, next =
3days, next = 5 days, fastest = 10 days).

Troubleshooting
1. Unit will not power up, LED not illuminated:
a. Conrm proper voltage is applied to the correct terminal(s).
a. Try an alternate power source. If using 24v try using 120v or vice versa.
2. Wiper sticks or stops on emitters:
a. Adjust height of emitters: loosen screw at base of emitter gently push or pull emitter to a height where
wiper just contacts emitter. Hold the emitter in place and tighten screw. Verify correct height after
tightening screw.
3. Wiper does not clean/ contact emitters:
a. Adjust height of emitters: loosen screw at base of emitter gently push or pull emitter to a height where
wiper just contacts emitter. Hold the emitter in place and tighten screw. Verify correct height after
tightening screw.
b. If the emitter is worn to the point where there is no adjustment, replacement emitters can be ordered
from GPS. Remove the screw and the emitter base, unplug the emitter from the connector. Plug the new
emitter in, reinstall base, adjust emitter height and tighten screw.
4. If unit does not operate properly after verifying the above instructions please contact GPS for additional
assistance.
