Installation
When replacing an existing soft start or upon new installation, remove any existing start capacitor from the circuit.
Mount the RVMS100S Soft Start in a safe location under the AC cowling/hood using the double sided adhesive tape and the 4 mounting screws provided in the wiring kit. Wire the RVMS100S per the wiring diagram below.
Please note: Upon initial installation the RVMS100S RV soft starter will initiate a 4-minute routine start delay indicated by a flashing “Red” LED indicator light. Power on the A/C unit and wait 4-minutes for the delay routine to conclude. This should follow with a successful call from the thermostat, A/C startup and the LED indicator light to change from “Red” to “Green”.
Important Safety Information
HIGH VOLTAGE WARNING – Always turn off power at the main service panel before installing
CAUTION: The RVMS100S must be mounted in an area where it will not be exposed to water or the elements. Exposure of the RVMS100S soft start to water can cause failure of the control and is a risk for fire or other electrical safety hazards.
We recommend that installation of any soft start be done by a certified technician or licensed electrician. All installations are to be done in accordance with local, state, and national electrical codes.
a) Disconnect factory installed compressor run wire from the run capacitor terminal (c/common/L2)
b) In its place, connect the (RVAC RED WIRE) to the run capacitor terminal (c/common/L2)
Connect the (RVAC BROWN WIRE) to the factory installed compressor run wire previously disconnected in step #1a
Connect the (RVAC BLUE WIRE) to the run capacitor terminal (herm/hermetic/start)
Splice the (RVAC BLACK WIRE) with the factory install compressor Overload Switch wire (OL/L1)
*If there is a Start Capacitor and or PTCR already in place, additional steps will be required to disconnect them.
