 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 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.
