4Lamp Replacement
The germicidal UV lamp in Tight Fit Kit needs to be replaced every two years.
Note: UV lamps will continue to emit visible light but lose germicidal eectiveness over time.
1. Remove O-rings. Remove lamp from lamp clips one side at a time.
2. Replace with new lamp and snap lamp into clips on each side. Reinstall O-rings.
2Power Supply Installation
IMPORTANT! Check which power supply
is included with your Tight Fit Kit before
connecting to power. Turn o main power
source before installation.
1. Find a suitable location for the power supply
inside the control panel of the air handler.
Install using the self-tapping screws and/or
the double sided tape.
2. Use the wiring diagrams below to connect to
power. The low-voltage power supply (18 thru
32 VAC) is marked "ER". The line-voltage (110
thru 277 VAC) power supply is marked "ST".
Heating Element Caution!
IMPORTANT! The Tight Fit Kit’s components are designed to withstand the typical
ambient temperatures found near fan coil and PTAC heating elements up to a constant
194°F (90°C). If installing the lamp near a heating element, secure the wires as far
away from the heating elements’ wires as possible to prevent them from touching the
element. In addition, use the included split-loom tubing for additional protection of
the power supply wires that may be mounted near the heating elements.
