Warm Tips:
The float switch is applied for weak current(0-0.2A) only, it cannot load directly; If the AC float switch is applied for triggering power device, relay or SSR for signal output transition in necessary; Please note that the maximum parameters of this SS2 float switch are theoretical values and are not intended for operation; The switch can be installed even slight slant and does not need to be level or plumb
Here are the specific installation steps for you:
INLINE INSTALLATION FOR (WALL) UNITS WITH VERTICAL DRAIN OUTLETS
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 drain outlets. This will prevent the switch from shutting off the fan coil or activating the alarm circuit 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 down from the primary pan outlet.
2. Glue 3/4'' Tee to bottom of stub with Tee stem horizontal and plumb.
3. Glue 3/4'' stub into horizontal outlet of Tee, insuring it is also plumb.
4. Ensure switch/plug assembly is inserted into 1'' inlet of PVC elbow so that float stem is at inside (bottom) of switch elbow. Float stem can be adjusted by threading it out of the plug assembly. DO NOT GLUE.
5. Glue a drain line with P trap onto the remaining outlet of Tee.
6. Connect the wires to VCC or the thermostat wires.
7. Test switch by lifting float with unit running. Unit should stop running if correctly connected. 8. Test all fittings and connections for plumbing leaks.
INSTALLATION FOR HORIZONTAL CEILING (PANCAKE) UNITS
NOTE: Primary drain (inline) is also recommended on horizontal ceiling (pancake) units as some flooding may occur if installed on auxiliary outlets, due to the closeness of the outlets to the top of the pan.
1. Glue 3/4'' stub to primary pan outlet.
2. Glue 3/4'' Tee onto stub with Tee stem positioned horizontally away from the unit and plumb.
3. Follow steps 3-9 under INLINE INSTALLATION FOR WALL UNITS, above.
