INSTALLATION INSTRUCTIONS Start Capacitor & Relay Kit
INTRODUCTION
These instructions cover the installation of Start
Capacitor & Relay Kits on split−system air conditioners
and heat pumps.
The Start Capacitor & Relay Kit is designed to boost
compressor starting torque.
!
ELECTRICAL SHOCK HAZARD
Failure to turn off electric power could result in
personal injury or death.
Before installing or servicing system, turn off
main power to the system. There may be more than
one disconnect switch, including accessory
heater(s).
WARNING
DESCRIPTION AND USAGE
The Start Capacitor & Relay kit causes the start capacitor
to give the compressor a hard boost at each start−up. The
relay takes the start capacitor out of the circuit after start−up.

INSTALLATION INSTRUCTIONS Start Capacitor & Relay Kit
INSTALLATION − Entry Models
NOTE: Remove and discard PTC start thermistor if
present.
Refer to Figure 1, Figure 2, and Figure 5.
1. Drill one 3.15mm hole for relay mounting in location
shown in Figure 2.
2. Attach start relay to control box as shown in
Figure 1 using one of the screws provided. Locate
the tab on back of relay to the hole that was drilled in
step 1.
3. Attach start capacitor to start capacitor strap
(before assembly to control box). Start capacitor
will face upward and the mounting tab will be to the
left hand side. See Figure 1.

Wire
4. Attach start capacitor and strap assembly to control
box as shown in Figure 1, using the hole shown in
Figure 2. One screw is provided with kit to mount
the capacitor strap.
5. Connect black wire to terminal 5 on start relay and
piggyback to terminal 21 on contactor. See
Figure 1.
6. Connect blue wire to terminal 2 on start relay and to
H on run capacitor. See Figure 1.
7. Connect brown wire to terminal 1 on start relay and
to either terminal on start capacitor. See Figure 1.
8. Connect yellow wire to open terminal on start
capacitor and to C on run capacitor. See Figure 1.
9. Installation complete, continue to System
Start−Up.
