STOP Condensation Leakage With A Low Voltage Overflow Shut-Off Safety Switch
• Model SS3 detects rising water in A/C condensate drain pans and interrupts the thermostat circuit to shut off the unit before overflows and flooding occur. The Model SS3 is designed to install in auxiliary (safety) drain pans. The included stainless steel clip snaps easily in place on most pan rims and holds firmly. Compact footprint fits well in tight spaces. Approved for use as a substitute for auxilliary condensate drains in jurisdictions where the International Mechanical Code applies.
• Model SS3 incorporates sealed, waterproof reed/magnet float switch technology for long term, reliable performance with no exposed electrical contacts to corrode, short out or fall off. Included sealed and pre-wired 6-Foot, 18-guage lead cables require one electrical connection during installation.
SPECIFICATIONS: 24 Volts A/C, 1.25 Amp GP Switching Current (Tested to UL 508 and Listed by UL
• at 6000 Cycles - Inductive Load). Reed Component Device is Separately UL
• Recognized at 2.5 Amps Max. Carry Current.
DIMENSIONS: Length (Overall - from bottom of stem to top of threads): 1-25/32-inch; Length (from top of pan rim to bottom of stem): 1-9/16-inch; Float Diameter: 1-inch; Float Height: 5/8-inch; Width (from verticle leg of pan clip to outside of float): 1-9/16-inch; Float Travel Distance (Max - distance required to close switch is slightly less): 1/4-inch.
Package Includes Pre-wired 6-Foot, 18 Gauge Lead Wires, Stainless Steel Clip/Brackett, Retaining Nut and 1/4-inch Hex Self Drilling Sheet Metal Screw.
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.
WARNING Electric shock hazard Disconnect power supply before installing Safe-T-Switch
to avoid electrical shock and/or equipment damage. Do not use on circuits exceeding 24 volts
to avoid damage to switch and shock or fire hazard.
CAUTION: May cause unit to cycle on and off rapidly as water level in pan approaches the shut-off
point prior to switch cycling totally off. Drain must be serviced if this occurs.
CAUTION: In any installation where property damage and/or personal injury might result from an
inoperative switch due to power outages, a backup system and/or alarm should be installed.
AUXILIARY DRAIN PAN INSTALLATION:
1. Disconnect power to unit at main panel.
2. Clip switch bracket onto side of pan at low end and press
firmly into place ensuring switch wires are positioned
up. Ensure float moves freely.
3. Secure bracket into side of pan using self-tapping sheet
metal screw through upper hole in bracket.
4. Ensure float switch assembly is firmly secured to
bracket. Ensure top of float is below rim of pan. Switch
will trip when water level reaches a point even with top
of float (when float is in down position). Sensitivity may
be adjusted by threading switch assembly downward out
of bracket if necessary.
5. Wire switch as instructed under Wiring, below.
6. Test switch by lifting float with unit on. Unit should stop running if switch is correctly wired.
7. Test switch sensitivity: Fill pan and confirm that switch stops unit before pan overflows.
8. Place warning sticker on air handler or condenser unit.
1. WARNING: Disconnect power to unit at main
panel prior to performing electrical work.
2. If not present, it is recommended that an inline fuse
and a delay to protect 24-volt circuit be installed.
3. Locate 24-volt thermostat cable entering air
handler unit. Disconnect or cut red wire and
connect to switch lead using wire nut. Connect
other switch lead to air handler terminal.
Incorporating switch in red circuit shuts entire unit,
fan continues to run if incorporated in yellow
circuit (inhibits mold during long absences).
4. Test switch by lifting float while unit is on. If wired
correctly, unit will stop when float is lifted.
