Description
Safe-T-Switch® Model SS700E is an overflow shut-off switch designed to fit in the
auxiliary pan eliminating the need to be mounted to the pan with screws or clips. The
SS700E’s logic circuit continuously samples the probes for water and shuts down the
system if water is detected.
Applications
Designed to sit directly in a secondary drain pan, eliminating screws and clips. Multiple
position option for the sensor and provides adjustable heights. Great for use in plastic
overflow pans with round edges.
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 the
warranty.
Secondary Auxiliary Drain Pan Installation:
Disconnect power to unit at main panel.
1. Sensor Position: Place the universal puck with the sensor attached into the drain pan.
Position the sensor so that the probes are facing downward and not in contact with the
pan. Adjust the probe height by threading the sensor into or out of the universal puck
using the supplied jamb nuts. Lock the sensor into position by tightening the nuts. Check
that probes are not in contact with the pan. 2. Wire Sensor as instructed under Wiring,
below. 3. Affix included warning sticker to air handler.
Wiring (see Figure 1):
Disconnect power to unit at main panel prior to performing electrical work.
1. In HVAC unit locate HVAC power wire going to "Wall Thermostat"(Typically red).
2. Break/Disconnect 24 VAC power wire going to "Wall Thermostat". 3. Connect "Red",
Input 24 VAC( hot) and Gray "common" wire of SS700E to 24 VAC (hot) secondary side
of transformer. 4. Connect "Purple" Normally closed wire of SS700E to Thermostat's
"R" terminal wire. 5. Connect "Black", Input 24 VAC (common) wire of SS700E to 24 VAC
(COMMON ) secondary side of 24 VAC Transformer or Thermostat's "C" terminal.
