This document provides installation, operation, and
maintenance information for the Titus HEPALERT™ LED
Light Kit installed on RadiaTec diffusers, specifically.
Additional information may be found at the Titus website,
www.titus-hvac.com.
General
The following information is to be used by the installer as a
guide. Since each installation is unique unto itself, only
general topics are covered. Topic order may not be the
same as required by actual installation.
The HEPALERT™ LED Light Kit provides an easy and
visible verification for HEPA filter cleanliness from the
occupied space. The kit uses pressure sensors and light
emitting diodes (LED) indicators to alert clean room users
when filter replacement is needed.
Tools and Equipment
In addition to the HEPALERT LED light kit the following
items (supplied by others) assist the installation process.
•
Transformer (Class 2 – 120 Vac to 24 Vac
transformer, rated 40 VA)
•
Power cord for transformer
•
Silicon sealant
•
Rubber tubing – 3/8-inch OD
•
Screw drivers (various sizes of Phillips and flat
blades)
The installer MUST read the entire contents of this guide
and develop a thorough understanding before beginning
installation.
•
Drill and drill bits (sizes needed are 3/16-, ¼-, 3/8-,
and 5/8-inch)
Due to a continuing program of product research, Titus
reserves the right to discontinue or change without notice,
any or all specifications or designs without incurring
obligations.
•
Unpack HEPAlert LED Light Kit and check contents
against Bill of Materials.
•
Sort contents, especially wire, screws, nuts according
to color, size, and type as listed on the Bill of
Materials.
•
Keep Bill of Materials readily available for reference.
•
Remove HEPA filter and back pan before attempting
installation.
This guide is not intended to supersede or circumvent any
applicable national, state, or local codes.
The installation is to be performed only by individuals
whose experience meets or exceeds the requirements of
the work involved.
Safety
The installation and / or servicing of comfort conditioning
equipment can be hazardous due to system pressures
and electrical devices.
Preparation
Caution: Only trained and qualified personnel
should perform service and/or installation.

Installation
1.
Determine and mark hole locations in back pan
(see Figure 1). Before drilling holes, position the
base bracket on back pan to verify alignment of
marked holes to bracket openings. Drill holes and
insert grommet into the 5/8-inch diameter hole.
2.
Determine and mark hole locations on HEPA filter
frame (see Figure 2). Before drilling frame holes,
verify the marked holes align directly under the
back pan holes in final installation. Insert grommet
into the 5/8-inch diameter hole.
3.
Determine LED bracket placement on the back
pan. Drill mounting holes on the side of back pan
(see Figure 3). The holes should be on the side of
the back pan adjacent to the holes drilled in Steps
1 and 2.

4.
Secure the pressure switch and terminal barrier
strip to base bracket using pan head screws and
hex nuts (see Figure 4).
5.
Secure base bracket to back pan using self-tapping
screws (see Figure 5).

Secure the LED assemblies to LED bracket using
self-tapping screws (see Figure 6).
Connect spade-tongue terminal on the white LED
assembly wire to the terminal barrier strip (see
Figure 8).
12.
Feed quick-connect terminals of LED assemblies
through the grommets on HEPA filter frame and
back pan (see Figure 6).
Connect the quick-connect terminal on the blue
LED assembly wire to the low-pressure terminal on
the pressure switch (see Figure 8).
13.
Connect the quick connect terminal on the red LED
assembly wire to high-pressure terminal on the
pressure switch (see Figure 8).
14.
Ensure all drilled holes and gaps in grommets and
tubing ports in back pan and HEPA filter frame are
sealed with silicon sealant.
15.
Connect quick-connect terminal of 8-inch red wire
assembly to pressure sensor power terminal.
Connect spade-tongue terminal to the terminal
barrier strip adjacent to white wire (see Figure 9).
Secure LED bracket to inside of back pan using
self-tapping screws (see Figure 6).
7.
8.
Insert 9-inch rubber tube through the 3/8-inch
diameter holes in back pan and HEPA filter frame.
Connect tube to the high-pressure port of the
pressure switch (see Figure 7).

Insert 3-inch rubber tube through the hole on back
pan and connect tube to the low-pressure port of
pressure switch (see Figure 7). Use silicon sealant
to seal both sides of the back pan hole to prevent
leakage.

16.
Secure a class 2 – 120 Vac to 24 Vac transformer
(rated for 40 VA. Transformer supplied by others.)
to back pan using self-tapping screws (see Figure
10).
17.
Connect spade-tongue terminal of 14-inch red wire
assembly to terminal barrier strip across from
previously connected red wire (see Figure 11).
18.
Connect spade-tongue terminal of 14-inch white
wire assembly to terminal barrier strip across from
previously connected white wire (see Figure 11).
19.
Feed quick-connect terminals of red and white wire
assemblies through grommet in side of base
bracket. Connect to transformer (see Figure 11).
NOTE: A single transformer may be used to
power multiple HEPAlertTM Kits. The 60-inch
red and white wire assemblies are supplied to
interconnect terminal barrier strips of
TM
HEPAlert Kits on adjacent diffusers.
20.
Place and align top cover to base bracket and
secure using self-tapping screws to secure (see
Figure 12).
21.

Startup and Operation
When power is supplied, the green LED comes on,
indicating the system is functioning.
The red LED comes on when a pressure differential of
50% is reached, indicating that filter needs to be replaced.
Once a clean filter is inserted in the filter frame, the green
LED comes on.
Calibration
Each HEPAlert kit sensor must be set based on the
module and inlet size. Use the information in the following
steps to calibrate the setscrew.
1.
Turn the setscrew clockwise to ensure it is in the fully
closed position. See Figure 14.
2.
Based on the module and inlet size, twist the
setscrew counter-clockwise the prescribed number of
turns from the fully closed position. See Table 1.
Figure 15 shows the setscrew at the fully open
position.
Figure 16 is a chart showing the pressure from supply
side of the HEPA filter.
