12 Volt Compressor Pressure Switch Replacement
(Page 1 of 2)
Tools and Materials Needed
1. Pressure Switch for the 12V Compressor (Spare) (#113545)
2. Two Adjustable Wrenches
Instructions
CAUTION: Ensure the power supply is disconnected from the
12V Compressor and the pressure has been fully vented
from the tank.
1. Pull to remove the two leads from the old pressure switch
on the 12V Compressor.
2. Use the two wrenches to unscrew and remove the
old pressure switch from the brass fitting on the 12V
Compressor. Use one wrench to stabilize the brass fitting,
and the other to unscrew the pressure switch (see below).
3. Remove the two covers from the connections on the new
pressure switch.
4. Screw the new pressure switch into the brass fitting and
tighten using the two wrenches.
5. Connect the two leads to the new pressure switch (this
switch has no polarity, so it does not matter which lead is
connected to which terminal).
