INSTALLATION INSTRUCTIONS

NOTICE: FAILURE TO READ AND COMPLY WITH ALL WARNINGS, CAUTIONS AND

INSTRUCTIONS PRIOR TO STARTING INSTALLATION MAY CAUSE PERSONAL INJURY

AND/OR PROPERTY DAMAGE AND VOID WARRANTEE.

It is recommended that this device be installed on the primary drain line between the pan outlet and P-Trap on

wall units with vertical pan outlets (i.e.: First Company; Janitrol) to prevent the unit from switching off in the

event condensate drips directly from the coil into the auxiliary pan outlet when the coil becomes dirty.

1. Disconnect power to unit at main panel and glue 5” stub dow

from primary pan outlet.

2. Glue ¾-inch slip Tee (not included) to bottom of stub with Tee stem horizontal and plumb.

3. Glue ¾” stub into horizontal outlet of Tee ensuring it is plumb.

4. Ensure switch/plug assembly is inserted into 1-inch inlet of PVC elbow so that float stem is at (inside)

bottom of PVC switch elbow. Float stem can be adjusted by threading it out of plug assembly. DO NOT

GLUE.

5. Place switch with wire leads up onto horizontal stub ensuring watertight seal. Switch may be angled up

to 20 degrees by rotating on stub. DO NOT GLUE.

INLINE INSTALLATION FOR (WALL) UNITS WITH VERTICAL PAN OUTLETS (See Fig. 1):

AUXILIARY DRAIN OUTLET INSTALLATION:

1. Disconnect power to unit at main panel and glue ¾” stub onto auxiliary drain outlet adapter on the equip-

ment supplied pan (secondary outlet of primary drain pan).

2. Ensure switch/plug assembly is inserted into 1-inch inlet of PVC elbow so that float stem is at (inside)

bottom of elbow. Float stem can be adjusted by threading it out of plug assembly. DO NOT GLUE.

3. Plumb ¾-inch inlet of PVC elbow to stub as close to drain outlet as possible with wires up. Position switch

level with or below outlet. Switch may be angled up to 20 degrees by rotating on stub.

4. Wire switch as instructed under Wiring, below.

5. Test switch: Remove switch/plug assembly from elbow and lift float with unit on. Unit should stop

running when float is raised.

6. Test switch sensitivity: Plug drain downstream from installation point and run unit to fill pan. Confirm that

float rises and unit stops before the pan overflows and check for plumbing leaks.

7. Place warning sticker on air handler or condenser unit.
