Step 8. Educate the Homeowner
Complete and attach the Next Service Date sticker on the access cover with a date
approximately 12 months from the install date for both the UV-C bulbs and the AC/PP purier.
Warn the homeowner to never take the unit out of the duct work without rst turning
the power switch o. Explain that all service must be performed by a licensed HVAC
professional or the warranty will be voided.
Explain the danger of looking at the light emitted from the QwikPure TripleGuard™ unit.

Replacing the Activated Carbon/Potassium Permanganate
(AC/PP) Purier
This nal stage of air purication should be changed annually.
Step 1. Check the status of the LED indicator lamps
Verify the unit is properly operating by verifying the GREEN LED and two ORANGE LEDs
are illuminated.
If the GREEN LED is not illuminated, there is either no electrical power is being supplied
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 and the GREEN
LED is not illuminated, contact Mainstream Engineering for replacement parts 1-800-
866-3550 or 1-321-631-3550.
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. Even if only
a single bulb has failed, always replace both bulbs. The life of each bulb is very similar
and the remaining bulb is likely to fail soon. Replacing both bulbs at the same time
helps you avoid unnecessary call-backs.
Step 2. Turn power o
Using the switch on the QwikPure TripleGuard™ turn the power o. All LEDs should
go o.
Step 3. Remove the AC/PP access plate by removing
