Important information about UV lamp replacements
Replace UV lamps each year to maintain optimum effectiveness
in keeping the air conditioner interior parts free of mold and other
bio-growth. After two-years germicidal effectiveness will have
diminished and the unit will automatically shut off until the lamps
are replaced.
Lamp replacement
1. Disconnect power to mini-split system.
2. Refer to installation instructions, reversing them as needed for
expired lamp removal and re-installation.
Maintenance
Never perform maintenance on the UV unit without
disconnecting power.
Typical maintenance consists of replacement of the ultraviolet
(UV) lamps. UV lamps undergo a photochemical process during
operation, that slowly reduces the amount of UV light generated
to disinfect the air and surfaces. For optimum disinfection, UV
lamps should be replaced annually. (See below: “Important
Information about UV lamp replacements”.)
When installing new lamps, ensure that the lamp glass is free
from any fingerprints or debris, as this may alter the path of the
UV energy. Use rubbing alcohol and a dry cloth to remove any
surface contamination.

Troubleshooting
Ultravation® UV disinfection equipment is designed to provide
many years of trouble free operation. In the unlikely event of a
problem, please contact your local HVAC professional or
Ultravation directly. Before calling for service, you should have
the model number, serial number, and purchase date.
If you are troubleshooting the unit, please check the following:
• Verify if in fact the UV lamp(s) is on or off—but never look at a
UV lamp in operation! You can safely confirm operation by
viewing the LED display on the power supply.
• Verify the unit has power. Check voltage requirement on power
supply label and confirm proper power is supplied.
• Be sure lamps are securely plugged into their sockets, no loose
wires, and in the correct orientation. (See page 4 and 5 of this
manual.)
• If possible install a new lamp to determine whether the problem
is the lamp or the power supply.
Remember: DO NOT look at UV light without proper eye
protection.
