CONDALERT™
CONDENSATE OVERFLOW DETECTION AND
CONTROL SHUTDOWN FOR SECONDARY/AUXILIARY
CONDENSATE DRAIN SYSTEMS
INTRODUCTION
Before proceeding with the installation or operation of the
Little Giant Condalert™, read all instructions thoroughly, as
well as complying with all Federal, State and Local Codes,
Regulations and Practices. The Condalert™ must be installed
by qualified personnel familiar with all applicable local electrical
and mechanical codes.
The Little Giant Condalert™ is designed for the air handling industry
to detect condensate drain overflow water in the secondary/aux-
iliary drain system and shut down the condensing unit so the
cooling coil will not produce more condensate water. When the
Condalert™ detects water, in the secondary drain system, the
Condalert™ will activate its visual red LED and audible buzzer
(Model LC-110), while at the same time shutting down the con-
densing unit to prevent condensate water accumulations. When
the probes are dried, the Condalert™ will automatically reset the
system to normal operation.
The solid state circuitry is encapsulated in epoxy, making the
unit waterproof and tamperproof. The probes are stainless steel
and will not rust. More than one Condalert™ may be installed
on a troublesome unit to provide complete area protection. The
Condalert™ may be connected to a monitoring unit or a remote
alarm.
The Condalert™ must be installed in a 24 Volt AC Class 2 control
circuit. Make electrical connections between the air handler
and the condensing unit control for proper operation.

SAFETY GUIDELINES
1. DO NOT USE WITH FLAMMABLE OR EXPLOSIVE FLUIDS
SUCH AS GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT
USE IN EXPLOSIVE ATMOSPHERES. SWITCH SHOULD
ONLY BE USED WITH WATER.
2. DO NOT HANDLE SWITCH WITH WET HANDS OR WHEN
STANDING ON A WET OR DAMP SURFACE, OR IN WATER.
3. DISCONNECT ALL ELECTRICAL SERVICE TO THE SWITCH
BEFORE WORKING ON OR HANDLING THE UNIT.
4. DO NOT CONNECT TO VOLTAGE ABOVE 24VAC MAXIMUM
OR AMPERAGE ABOVE 1.0 AMP.
5. DO NOT OPERATE UNLESS COMPLETELY ASSEMBLED.
6. IN ANY INSTALLATION WHERE PROPERTY DAMAGE AND/OR
PERSONAL INJURY MIGHT RESULT FROM AN INOPERATIVE
SWITCH DUE TO POWER OUTAGES, OR ANY OTHER REASON,
A BACKUP SYSTEM(S) AND/OR ALARM SHOULD BE USED.
7. DO NOT MODIFY, CUT, SAW, SAND OR GRIND ANY PART
OF THE CONDALERT. DOING SO MAY CAUSE HARMFUL
EMISSIONS.
CONNECT THE CONDALERT BETWEEN THE LOW VOLTAGE
(24 VAC) HVAC CONTROLS AND THE CONDENSING UNIT
CONTROL CIRCUIT.
IF THE CONDALERT GOES INTO ALARM CONDITION DUE TO
WATER DETECTION, THE RED LED AND ALARM BUZZER (ON
MODELS WITH BUZZER) WILL ACTIVATE. AT THE SAME TIME
THE COMPRESSOR/CONDENSOR UNIT WILL SHUT DOWN. THE
AIR HANDLER FAN WILL STILL OPERATE TO PROVIDE AIR
CIRCULATION IF INSTALLED PROPERLY.
IF THE CONDALERT IS CONNECTED BETWEEN THE THERMOSTAT
AND HVAC CONTROL SYSTEM, THIS WOULD PREVENT AIR
HANDLER FAN FROM OPERATING.
1. Turn off all power to the air handler and condensing unit.
Install Condalert Control Main Unit in Secondary/Auxiliary Pan
2. Determine location for leak detection. Place the Condalert in
drain pan whenever possible. Condalert may be set in pan or
attached in location using the double sided tape provided (see
Figures 1 and 2). Do not attach to the pan until testing is complete.
