CAUTION
This unit must be installed and serviced by a licensed HVAC contractor
or electrician. Failure to do so will void the warrant of the product.
•
UV Light in operation; disconnect unit from power cord before
servicing; failure to follow warnings may result in severe eye damage
•
Live voltage may be present
•
Disconnect power at the breaker or fuse panel before servicing
unit; always follow OSHA lockout procedures to prevent accidental
exposure to electrical energy
WARNING
1 .
Check the incoming voltage by unplugging the power cord from the side of the ActivePure
®
Induct
Guardian I and placing one probe on the outside of the plug and the other on the inside of the plug .
Voltage measurement should read 18 – 32 VAC . If no voltage is present, replace the transformer
supplying power to the ActivePure Induct Guardian I .
2 .
Leave unit attached to ducting . Remove four (4) Phillips head screws from the cover of the unit .
Remove the cover . Unplug the black and white wires from the ballast . Check incoming voltage by
placing Multimeter probes on the two exposed wires . Voltage measurement should be between 18
– 32 VAC . If there is no voltage reading, power is not supplied to the unit . Check power source and
verify Induct Safety Switch is fully depressed . Safety switch plunger is located underneath the unit
and is depressed when unit is secured to mounting plate .
3 .
Re-plug the black and white wires to the ballast .
4 .
Remove unit from the duct by taking off the four (4) 11/32 thumb
nuts that secure the unit to the mounting plate .
5 .
Remove the two (2) Phillips head screws that hold the cell
assembly in place . Remove the UV bulb from the 4-pin connector
by placing a small flat head screwdriver between the 4-pin
connector and the UV bulb base . Gently pry and lift up on the Cell
until the UV bulb is unseated from the 4-pin connector, remove
the Cell Assembly .
6 .
Check the continuity of the UV bulb filaments with a Multimeter by placing the Multimeter probes on
the UV bulb pins that are closest to each other . The Multimeter should beep if the filaments are not
broken . Resistance can also be checked if continuity is not available on the Multimeter . Resistance
should be between 3 – 5 ohms . If continuity or resistance check is bad, replace the ActivePure
®
Cell .
7 .
If continuity or resistance check is good, replace the ballast . To replace the ballast follow the steps
listed on pages 11 and 12 .
