8. Terminate one of the leads with the insulated 1/4"
female push on terminal. Terminate the other lead with
the insulated 1/4" male terminal. Both terminals are
supplied with the kit.
9. PACKAGE UNITS: Refer to the appropriate wiring
diagram in these installation instructions. Find the
orange wire currently in the unit running from the
economizer plug to the anti short cycle timer (single
phase air conditioners), contactor (three phase air
conditioners), or defrost board (heat pumps). Remove
this orange lead from the anti short cycle timer,
contactor, or defrost board as appropriate. Replace the
uninsulated terminal on this wire with a insulated 1/4"
female terminal provided in the kit. Connect this
insulated female terminal to the insulated male terminal
on one of the pressure switch leads. Connect the
insulated female terminal on the other pressure switch
lead to the anti short cycle timer, contactor, or defrost
board as appropriate.
10. SPLIT SYSTEMS: Refer to the appropriate wiring diagram
in these installation instructions. For air conditioners,
wire pressure switch in series with T1 of anti-short cycle
timer and indoor thermostat (yellow wire) as shown in the
wiring diagram. For heat pumps, remove and discard
yellow jumper wire currently between T1 and Y on the
defrost control board. Connect one lead of the pressure
switch to T1 and the other lead to Y of the same board.
11. If you are installing a low pressure switch or other
limiting device in addition to the high pressure switch
in this kit, wire the switches in series as shown below.
12. Insure the unit is wired up as shown in the wiring
diagram in this kit.
13. Tie wires back as necessary.
14. Replace all removed panels.
15. Test operation of unit.
The installation sequence is as follows:
1. Read these instructions completely before proceeding.
2. Disconnect all power to the unit.
3. At front of the unit remove the service panel to the
control box. This will have all of the electrical control
components within and in the case of the gas electric
units the gas control components as well.
4. Remove the front panel with the service ports and drain
tube opening from the unit.
5. There are two service valves on the unit. Locate the
one in the 1/2" diameter compressor discharge line.
6. Remove the cap from the service valve. Mount the
pressure switch on the service valve and tighten. If
desired, a service adapter tee is supplied with the kit
to keep a service port available. Be sure that the
service valve cores shipped with the kit are inserted in
the valve bodies before proceeding. If used, place the
cap removed from the service valve on the service
adapter tee.
7. Route the two wire leads from the switch through the
wire grommet at the top of the panel separating the
compressor from the control box.
INSTALLATION
These instructions are primarily intended to assist qualified individuals experienced in the proper installation of heating
and/or air conditioning appliances. Before beginning the installation, read these instructions thoroughly and follow all
warnings and cautions in the instructions and on the unit. Improper installation, service, adjustment, or maintenance can
cause explosion, fire, electrical shock, or other conditions which may result in personal injury or property damage.
INTRODUCTION - High Pressure Cut-Out Kit 913550
The High Pressure Cutout Kit is designed for use in single package air-conditioners and heat pumps, split system air-
conditioners and heat pumps, and gas electric products. The kit consists of a pressure switch, a service adapter tee,
and miscellaneous parts for mounting. The pressure switch opens when the head pressure rises above 425 psig and
closes again when the head pressure drops below 350 psig. Opening of the switch, stops the compressor and initiates
the 5 minute compressor delay. The system will not start again until the head pressure drops below 350 psig and a 5
minute time period has expired.
WARNING:
To avoid risk of electric shock, personal injury,
or death, disconnect electrical power to the
unit before performing any maintenance or
service. The unit may have more than one
electric power supply.

INTRODUCTION - Low Pressure Cut-Out Kit 913551
The Low Pressure Cutout Kit is designed for use in single package air-conditioners and heat pumps, split system air-
conditioners and heat pumps, and gas electric products. The kit consists of a pressure switch, a service adapter tee
and miscellaneous parts for mounting. The pressure switch opens when the suction pressure drops below 25 psig and
closes again when the suction pressure rises above 50 psig. Opening of the switch stops the compressor and initiates
the 5 minute compressor delay. The system will not start again until the suction pressure rises above 50 psig and a 5
minute time period has expired.
INSTALLATION SEQUENCE
The installation sequence is as follows:
1. Read these installation instructions completely before
proceeding.
2. Disconnect all power to the unit.
3. At the front of the unit remove the service panel to the
control box. This will have all of the electrical control
components within and in the case of the R4 units the
gas control components as well.
4. Remove the front panel with the service ports and
drain tube opening from the unit.
5. There are two service valves on the unit. Locate the
one in the 3/4" or 7/8" diameter compressor suction
line.
6. Remove the cap from the service valve. Mount the
pressure switch on the service valve and tighten. If
desired, a service adapter tee is supplied with the kit
to keep a service port available. Be sure that the
service valve cores shipped with the kit are inserted
in the valve bodies before proceeding. If used, place
the cap removed from the service valve on the
service adapter tee.
7. Route the two wire leads from the switch through the
wire grommet at the top of the panel separating the
compressor from the control box.
8. Terminate one of the leads with the insulated 1/4"
female push on terminal. Terminate the other lead
with the insulated 1/4" male terminal. Both terminals
are supplied with the kit.
9. Find the orange wire currently in the unit running from
the economizer plug to the anti short cycle timer
(single phase air conditioners), contactor (three
phase air conditioners), or defrost board (heat pumps).
Remove this orange lead from the anti short cycle
timer, contactor or defrost board as appropriate.
Replace the uninsulated terminal on this wire with a
insulated 1/4" female terminal provided in the kit.
Connect this insulated female terminal to the
insulated male terminal on one of the pressure
switch leads. Connect the insulated female terminal
on the other pressure switch lead to the anti short
cycle timer, contactor, or defrost board as appropriate.
10. SPLIT SYSTEMS: Refer to the appropriate wiring
diagram in these installation instructions. For air
conditioners, wire pressure switch in series with T1 of
anti-short cycle timer and indoor thermostat (yellow
wire) as shown in the wiring diagram. For heat pumps,
remove and discard yellow jumper wire currently
between T1 and Y on the defrost control board.
Connect one lead of the pressure switch to T1 and the
other lead to Y of the same board.
11. If you are installing a low pressure switch or other
limiting device in addition to the high pressure switch
in this kit, wire the switches as shown below.
12. Insure the unit is wired up as shown in the wiring
diagram in this kit.
13. Tie wires back as necessary.
14. Replace all removed panels.
15. Test operation of unit.
