SureStart® 115/230V HVAC installation – SSxB Series:
This model SureStart® functions only as a soft starter, a contactor is still required. This model can be suitable for a wide range of applications. Some
degree of care is needed to determine the correct wiring.
Caution& Warning:
1 All voltage to equipment MUST be disconnected before removing any devices.
2 Allow 2 minutes to discharge run capacitor before disconnecting.
3 Do not swap the Run & Start Windings.
4 Prior to installation, be sure all start capacitors & start relays, along with hard-starters and/or any other start-assist devices, are removed.
5 The start capacitor is built into the soft starter.
6 Loose terminals can lead to heating & subsequent damage to the soft starter. As per, UL508 standard, ensure below tightening torques.
7 OPENING OF THE SOFT STARTER UNIT WILL VOID THE WARRANTY!
