Hubbell Gard-It Pressure Switch 69WC7 Instructions

Position the switch lengthwise so that the two adjacent screws marked "Line" are on top and the two adjacent screws marked "Motor" are on the bottom.

Turn off the power to your pump or compressor motor and turn your current pressure switch off if it has an on-off switch. Disconnect the wires that connect your pressure switch to your motor.

Measure a sufficient length of cable from your existing switch to the location where you want to mount your Hubbell Gard-It Pressure Switch 69WC7.

Strip the main insulation of each end of your electrical cable to about 1/2-inch from the end to reveal the strands of insulated wire under the main cable insulation. Separate the strands of wire and strip about 1/4-inch of insulation from the end of each strand.

Open the "Line" terminals of your 69WC7 with a screwdriver and hook one exposed end of one wire around the left terminal screw. Attach the other end into the left terminal of your pressure switch that was connected to the motor. Tighten the terminal screw of your 69WC7 and tighten the screw or other fastener of your pressure switch terminal. Repeat for the right terminal.

Check if the cable that you disconnected from your existing pressure switch is long enough to run from the motor to the motor terminals of your 69WC7. Measure and cut sufficient new cable to run the entire distance if the existing cable is not long enough. Strip the insulation according to Step 4. Do not splice new cable onto your existing cable to extend its length under any circumstances.

Connect the new cable to the motor terminals if necessary. Open the motor terminals of your Hubbell Gard-it and wrap the exposed end of each wire around its corresponding left or right terminal screw. Tighten the terminal screws.

Run a ground wire from the optional ground or ground screw to a proper grounding surface if desired.

Consult your equipment owner's manual to determine the proper pressure range between which your pump should start and stop. Insert your screwdriver into the slot of the steel pressure range screw at the bottom left of your Hubbell Gard-it. Turn the screw clockwise (away from you) to increase the range of pressure (pounds per square inch) settings between which the switch will turn your pump on and off, or turn it clockwise (toward you) to decrease the range.

Consult your equipment owner's manual to determine the lowest safe pressure at which your pump should cease to operate. Insert your screwdriver into the slot of the plastic differential adjustment screw at the bottom left of your Hubbell Gard-it. Turn the screw clockwise (away from you) to select a lower pressure (pounds per square inch) setting for emergency cut-off, or turn it clockwise (toward you) to specify a higher pressure setting.

Insert a mounting screw in the mounting hole at the bottom of your Hubbell Gard-It Pressure Switch 69WC7 and mount it to a wood or metal surface indoors or outdoors as you wish.

Turn your pump back on and reset your existing pressure switch as necessary. Operate your pump as usual, and change the settings in Steps 9 and 10 if the pump cuts off too frequently.
