RV Air Conditioning Soft Starter Installation Guide

RV AIR-CONDITIONING SOFT-STARTER
SpartanStart / Single Phase1/4
Instruction Guide

The SpartanStart functions as a soft-starter, and is designed to be used across a wide range of RV air conditioning units. Unlike commonplace designs, this soft-starter only requires access to the compressor’s three wires (Run, Start and Common).

Parts List:

1 x SpartanStart Soft-starter
6 x Splice Connectors
1 x Alcohol Wipe
Warning:

1. This model does NOT electrically isolate the control box from the compressor. A suitable contactor or relay is necessary.
2. All voltage to equipment MUST be disconnected before removing any devices.
3. Allow 2 minutes to discharge run capacitor before disconnecting.
4. Do not swap the Run & Start Windings.
5. Poor crimping can lead to heating & subsequent damage to the soft starter.

LED Flash Codes:

Slow (1/2 sec)| Under-voltage detected
Overload protection detected

Field Wiring Terminals (Applicable if wire harness is not provided):
Wire Range: 14 AWG Cu, stranded, for all terminals (Run Winding (R) and Active(T2))
Tightening Torque: 4.4 lbs-in [0.5 Nm] terminals.
Field wiring conductors shall be rated 167°F [75°C] Suitable for use on a circuit capable of delivering no more than 5000rms symmetrical amperes, 120 volts maximum, when protected by a non-time delay RK5 fuse or circuit breaker rated 80A, or a time delay fuse rated 70A. The device does not provide current limiting control or equivalent.
Spartan Start is NOT an overcurrent protection device and must NOT be used as a replacement for any primary circuit overcurrent protection.
WARNING:
This product can expose you to chemicals which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

SpartanStart should be installed by qualified technician

Acquire manufacturer’s wiring diagram for the air-conditioning unit.
Acquire manufacturer’s wiring diagram for the air-conditioning unit.
Turn off power to the RV unit.
Verify from the manufacturer’s wiring if there any start-assist devices such as start capacitors, start relays or PTCRs which may be present.
If present, these need to be removed. Follow the Start winding connection from Compressor into the control box. This should terminate onto a run capacitor (HERM terminal, in case of a dual capacitor). If the same terminal has other wires terminated, these must be disconnected and electrically isolated.

placing the soft-starter and its wiring in the following areas.
• In the direct path of an air vent,
• In proximity (less than 2 inches) to copper pipes (inlet or discharge),
• Near rotating mechanical parts,
• Near heat sources,
• A place that interferes with closing the top hood.
Suitable locations to place the soft-starter are:
• Inside/adjacent to the foam cover,
• On the base floor.|
4| Cut the compressor’s three wires at a location within range of the soft- starter’s wire harnesses.|
5| Clearly identify the supply and compressor sides of the connections.
In this illustration, Upper section is Compressor side and Lower section is Supply side.|
6| 6a) On the supply side, carefully match the cut run, start, and common wires of the A/C unit with the run, start, and common wires on the SUPPLY side of the soft starter. Strip each wire by ½” and terminate all 3 connections using closed end splice connectors, see diagram below. 6b) On the compressor side, carefully match the cut run, start, and common wires coming from the compressor with the run, start, and common wires on the COMPRESSOR side of the soft starter. Strip each wire  by ½” and terminate all 3 connections using closed end splice connectors. Ensure that all 6 crimp connections are firm and secure.|
7| Ensure that the wire harness on both sides is securely routed within foam guides inside the unit.|
8| Clean the chosen mounting surface for the soft starter using the included alcohol pad.
Secure the soft-starter box in place with the adhesive tape on the backside and press firmly.|
9| Securely replace any foam covers and the top hood. Turn on power and verify operation.|
