REPLACING UVC GERMICIDAL LAMPS
7
1. Always wear protective eye goggles when servicing UVC germicidal lamps.
2. Unplug the power cord from main outlet on the Cube unit.
3. Remove the central Cube metal cover which is held in place with eight (8) screws. This will allow
access to the 3 PRO-Cell™ modules and electronics.
4. Next to the MERV13 filter is the PRO-Cell/MM2025C Master Module. Unplug the power cord, remove
service panel metal cover from the PRO-Cell/MM2025C Master Module and set aside metal cover.
5. The remaining two modules are the PRO-Cell/SM2025 Slave Modules. Unplug the low voltage wires
from the master module and the two slave modules.
6. Unplug the UVC germicidal lamp wires from each of the lamp connections.
7. Each module is held in place by a retaining bracket by two (2) thumb screws. Unscrew the thumb
screws. Set aside thumb screws and retaining brackets.
8. Carefully slide forward the PRO-Cell™ Module to a point where access to the far end of the UVC
germicidal lamps can be reached, or fully withdraw the module completely from the frame. Loosen the
UVC germicidal lamp clamp thumb screw located at the far end of the UVC germicidal lamp so as to be
able to carefully remove the lamp through the rubber grommet on the front of the module.
IMPORTANT
AVOID TOUCHING THE NEW UVC GERMICIDAL LAMPS WITH BARE HANDS AS THE OIL ON THE SKIN CAN IMPEDE LAMP
PERFORMANCE OR CAUSE PERMATURE FAILURE OF LAMP ILLUMINATION.
THE USE OF COTTON GLOVES OR PAPER TOWELS IS PREFERRED WHEN HANDLING THE UVC GERMICIDAL LAMPS.
9. Replace with new UVC germicidal lamps: re-insert the lamp through the rubber grommet at the front,
and insert into the UVC germicidal lamp clamp at the far end until the plastic shield of the lamp rests
softly against the frame.
10. Finger-tighten the thumb screws on far end of the UVC germicidal lamp holding clamp.
11. Replace all six (6) lamps in the same fashion.
12. Fully re-insert the 3 PRO-Cell™ modules into the frame. Replace retaining bracket and re-fasten each
with two thumb screws. Repeat steps on all modules.
13. Re-attach all low voltage wires and power cord.
14. Re-attach the central PRO-Cell™ module metal cover with screws supplied making sure the rubber
gaskets are properly seated to assure no air leakage.
15. Re-connect power cord and check through the six UVC germicidal lamp view ports for illumination.
