P100 Series Encapsulated Pressure Controls
A high pressure manual reset lockout is available on
some models. See Figures 1, 2 and 3, and refer to
Table 1 for standard models available from your
Johnson Controls/PENN sales representative.
Additional pressure connection styles, pressure
setpoints, and electrical ratings are available on
non-standard models, in quantity orders only. Contact
your Johnson Controls/PENN sales reprentative or
distributor, or Refrigeration Application Engineering at
(800) 275-5676 to order non-standard P100 pressure
controls.

pplication
A
The P100 Series Encapsulated Pressure Controls are
compact, economical, direct-mount, snap-action,
On/Off pressure controls, available in a wide variety of
factory-calibrated, non-adjustable pressure setpoints.
The P100 controls are designed primarily for direct or
pilot duty control of motors and other refrigeration or
air conditioning application loads requiring precise,
repeatable pressure control over a wide range of
ambient conditions.
Standard P100 models come with 1/4 in. SAE female
flare fitting with integral Schrader valve depressor and
48 in., No. 18 American Wire Guage (AWG) insulated,
stranded-copper wire leads. See Figures 3 and 4.

A bowed, stainless steel, snap-acting disc reverses its
curvature when pressurized to the specified actuation
setpoint. When the disc snaps, it drives a set of
electrical contacts open or closed, depending on the
control’s switch action.
When the applied pressure returns to the specified
deactuation setpoint on
snap-acting disc and electrical contacts return to their
original postion.
On high pressure
remains in the reversed position and the electrical
contacts remain open until
pressure is reached
pushed. After deactuation pressure is reached, push
the manual reset button to return the contacts to the
closed position.
A “trip free” internal latching mechanism on manual
reset controls does not allow the control to be reset
until the system pressure reaches the specified
deactuation setpoint, even if the reset button is held
fully depressed.

Do Not Overtighten Flare Nuts on Pressure
Connection Fittings.
Overtightening flare connections
may damage the threads on the flare nuts or flare
connectors and result in refrigerant leaks. Do not
exceed 9 lb.ft (12 N.m) of torque when tightening
brass flare connections.
Avoid Severe Pressure Pulsation on High-Side
Pressure Connections.
Install P100 controls on
pressure tap points away from the compressor
discharge to minimize the effects of pressure pulsation
from reciprocating compressors.

WARNING:
Risk of Electrical Shock.
Disconnect power supply before
making electrical connections to
avoid possible electrical shock
or equipment damage.

The compact size and lightweight construction of the
P100 series controls allows mounting the control
directly to the refrigeration piping or almost any other
convenient pressure tap point on the system. Observe
the following guidelines when installing the
P100 controls.
IMPORTANT: If these controls are installed on
equipment containing hazardous
or regulated materials, such as
refrigerants or lubricants, the
installer and user should observe
all regulations governing the
handling and containment of
those materials.
IMPORTANT: Pressure tap points should be
located on the top side of the
refrigerant lines. This reduces the
possibility of sediment
accumulating in the control.
IMPORTANT: Make all wiring connections in
accordance with the National
Electrical Code and all local
regulations. Use copper
conductors only. Do not exceed
the control’s electrical rating.
Standard P100 Encapsulated Pressure Controls are
available with several switch options. Check the label
on the control body for model number. Refer to the
following guidelines, diagrams, and the electrical
ratings in Table 2 when wiring the standard P100
controls.

IMPORTANT: After mounting and wiring
control, attach a reliable set of
gauges to the controlled
equipment and operate the
equipment at least three cycles
at the pressures necessary to
verify control setpoints and
proper operation.
epairs and Replacement
R
Field repairs to the P100 pressure controls must not
be made. For a replacement control, contact an
authorized Johnson Controls/PENN Sales
Representative or Distributor, or Refrigeration
Application Engineering at (800) 275-5676.
Do not exceed manufacturers’
recommended pressure ratings
for the controlled equipment or
any of its components when
operating the controlled
equipment.
