 Power Supply Installation

 

IMPORTANT! Check which power supply 

is included with your Tight-Fit Kit before 

connecting to power. Turn off 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.

2.

 Use the wiring diagrams below to connect to 

power. The low voltage power supply (18 to 

32 VAC) is marked "ER". The high voltage (120 

to 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 slit loom tubing for additional 

protection of the power supply wires that may be mounted near the heating elements.

 UV Lamp Connection

1. 

When all the other components are properly installed connect the UV Lamp 

cable to the Power supply cable. 

2.

 Make sure the flanges are aligned and then push the connectors firmly 

together. A tight connection ensures a proper water-resistant seal.
