MOUNTING

1. Disconnect power to the condensing unit or heat pump at the
disconnect switch and/or main electrical panel. Ensure that all
sources of power are disconnected before proceeding.
2. Label wires and remove old contactor.
3. Find a suitable mounting location inside the control box. Rotate
SureSwitch as necessary to allow space for wiring and other
components.
4. Loosen four housing captive screws attaching the bottom
mounting plate to the main housing and separate the mounting
plate from the main housing.
5. The bottom of the mounting plate has four mounting holes that
match the typical mounting screw locations of a single or two-pole
contactor. Secure the bottom mounting plate to the control box
using the two self-tapping screws provided.
6. Replace the main housing on the mounting plate and secure by
tightening all four housing captive screws. Take care to avoid over
tightening.
7. Connect line and control voltage wiring. Refer to the wiring
diagrams provided for more information. Tighten the L1, L2, R and
C lugs to the recommended torque specifications.
8. Affix the provided Quick Reference Label inside the control box for
future service.
