head screwdriver
• Needle nose pliers
• Emery cloth or evaporator cleaner
• Wire cutter
• Wire stripper
• Fish tape (possibly needed)
• Insulation tape, hose clamp, or wire ties (possibly

Pre-Installation
1. Disconnect all power to the control at the circuit breaker
or disconnect switch. More than one circuit breaker or
switch may be required to de-energize the control and
all connected loads.
2. Plan the length of field-supplied copper wire needed
to connect the thermistor probe from the evaporator
coil to the input lead. (This wire may be #18-14 AWG
shielded or unshielded up to 400 ft (121.92 m) long).
3. The existing control may be installed in an enclosure (as
shown in FIG. 3, for example) or secured via a bracket
inside the condensing unit control panel (as shown in
FIG. 4, for example). The installation of the
I
CUBE™
module is the same for both instances.
4. If applicable, open the enclosure door.
5. If applicable, remove and discard the existing dead front
cover. See FIG. 2.
