Install Instructions
Step 4. Replace the AC/PP purier and complete the installation.
a. Insert a new AC/PP unit into the QwikPure TripleGuard™ by sliding the unit into
the guides.
b. Replace the AC/PP access cover.
c. Install a new Next Service sticker with the replacement date for the AC/PP purier
appropriately 12 months from today’s date. Transfer the bulb replacement date
to the sticker as well.
d. Turn power back on and check for proper function. All three LEDs will be
illuminated.
Replacing the UV-C Lights
The UV-C lights are the rst stage of air purication and should be changed at least once
a year.
Step 1. Check the status of the LED indicator lamps
Verify the unit is properly operating, by checking the Green LED is illuminated.
If the GREEN LED is not illuminated, there is either no electrical power is being suppled
to the unit (check the fuses) or the electronics control module unit has failed and
must be replaced. No serviceable electrical components are within the QwikPure
TripleGuard™ unit’s electronic control module. If power to the unit has been veried,
contact Mainstream Engineering for support at 1-800-866-3550 or 1-321-631-3550.
If the Next Service sticker is indicating that it is time to replace the UV-C bulbs, change
them even if they are still working as indicated by the ORANGE LEDs being illuminated.
If one or both of the orange LEDs are not illuminated and the GREEN LED is illuminated,
one or both of the bulbs have failed and BOTH bulbs should be replaced. Always
replace both bulbs. The life of each bulb is similar and the remaining bulb is likely to
fail soon. Replacing both bulbs at the same time will help you avoid unnecessary call-
backs.
Step 2. Turn power o and disconnect electric power
Turn power o at the breaker powering the QwikPure TripleGuard™ (not at the switch
on the unit). All LEDs will go o when the power is o. Unplug the power lead from the
electronics control module.
Step 3. Remove the AC/PP unit from the QwikPure TripleGuard™,
following the Instructions for AC/PP removal (described previously).
Step 4. Remove QwikPure TripleGuard™ unit from the ductwork.
If the QwikPure TripleGuard™ is installed directly into a sheet metal duct, remove the
retaining sheet metal screws, and carefully slide the unit out of the duct.
If the QwikPure TripleGuard™ is installed onto a ber duct board, remove the four wing
nuts and carefully slide the unit out of the duct.
