Installation Instructions for the
Honeywell Pressure Switches
High Pressure: HP Series, HE Series
Medium Pressure: MH Series, ME Series
Low Pressure: LP Series, LE Series
(3.5 psi to 4500 psi [0,24 bar to 310,26 bar])
MECHANICAL REQUIREMENTS
Installation Requirement
The Honeywell Pressure Switches, High Pressure, Medium
Pressure, and Low Pressure, are capable of being mounted in
any orientation via a threaded port. A 27 mm hexagonal wrench
should be used to install the pressure switch. Installation torque
should be based on the information in Table 1. Installation of
the pressure switch shall permit usage of maximum 27 mm hex
box spanner, modified socket wrench, and open-ended wrench.

INSTALLATION
,
CAUTION
PRODUCT DAMAGE
•
Use a hex wrench for installation. DO NOT exceed a
torque level based on the information in Table 1. Never
apply torque to the connector housing or the body of the
pressure switch.
•
Do not subject the pressure switch to high tempera-
tures from soldering, brazing, or welding of the system
plumbing or operating environments above the specified
maximum temperature.
Failure to comply with these instructions could result in
death or serious injury.
Ensure the power supply is off while wiring.
The pressure switch can withstand a side load (acting
perpendicular to the mounted axis) of 100 Newton at the
end of the integral connector in its mounted orientation. This
load requirement is for any incidental physical abuse during
installation or intended use.

WIRING INSTRUCTIONS
50038194
,
CAUTION
PRODUCT DAMAGE
•
Do not exceed the operating pressure.
Failure to comply with these instructions could result in
death or serious injury.
If the operating pressure is exceeded, the life of the Honeywell
pressure switch may be reduced and electrical failure may
occur. Both static and dynamic over-pressuring must be
considered, particularly in hydraulic system applications.
Hydraulic pressure fluctuations can have very high and rapid
pressure spikes, as in a water hammer effect. The high pressure
versions (HP Series, HE Series) have a snubber feature built-in
to reduce the peak pressure applied to the pressure switch. The
medium and low pressure versions (ME Series, LP Series, LE
Series) do not employ this feature.
If system pressure pulses are expected, choose a pressure
switch with a proof pressure rating high enough to allow
operation at the highest expected pressure spikes.
NOTICE
To ensure proper environmental sealing and electrical
connections when using a connector, follow the connector
manufacturer’s installation guidelines. All terminal cavities
must be sealed using the correct wire gauge and seal com-
bination. If only two leads are used, any additional terminal
cavities should be sealed per the connector manufacturer’s
installation guide. Honeywell recommends using a crimping
tool for crimping wires to the connector terminals. Contact
the individual connector manufacturer for connector wiring.
FUNCTIONAL TEST
Connect the pressure switch to the pressure source (off).
Based on the pressure switch’s specified normally open (NO) or
normally closed (NC) output, connect the electrical termination
to a dc voltage supply. With no pressure on the pressure switch,
turn on the power supply and ensure that the pressure switch
is in the correct NO or NC position. Apply the appropriate set
point pressure to ensure that the NO or NC contact position of
the switch will switch over.
MEDIA COMPATIBILITY
,
CAUTION
PRODUCT DAMAGE
•
Use non-abrasive, chemically compatible media to pre-
vent damage to the pressure switch.
Failure to comply with these instructions could result in
death or serious injury.
The pressure switch’s fluid path is an assembly of zinc-
plated steel, stainless steel, DuPont™ Teflon
®
-coated Kapton
®
,
and nitrite. The Series is compatible with a wide variety of
petroleum-based fluids, air, water, and mineral oil-based brake
fluid. Please confirm your media compatibility or speak with a
Honeywell Application Engineer.
