(2) Conduit connectors (straight or elbow as required)
(11) High voltage wires matched to the load of the heaters,
fans, liquid line solenoid, alarm (if used), and the controller.
(8) Spade Connectors matched to the gauge of high voltage
wires
Wire labeling (numbers, colors, etc.)
Additional wire ties
18 gauge twisted shielded pair (if extending sensor wires)
Foam insulation if running wires outside the space.
Silicone (for sealing any box penetrations)
