sure connection. Low pressure and differential pressure units, models
520-535, 540-543, 544-548, are also available with an optional
surface mounting bracket. Should the control be installed where con-
densation is expected, vertical mounting is recommended as a means of
keeping water away from switch terminals.
Never use the enclosure for leverage to hand tighten the pressure con-
nection. Always use a wrench to tighten the pressure connection to the
pipe.To prevent damaging the pressure sensor, use a back-up wrench
to hold the hex nut in place when surface mounting.
On models supplied with an external manual reset button, be sure to
leave sufficient finger space over the reset button for the operator to
reset the control. See Mounting Diagram.
WIRING
DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING.
ELECTRICAL RATINGS STATED IN LITERATURE AND ON
NAMEPLATES SHOULD NEVER BE EXCEEDED. OVERLOAD
ON A SWITCH CAN CAUSE FAILURE ON THE FIRST CYCLE.
WIRE UNITS ACCORDING TO NATIONAL AND LOCAL ELECTRICAL
CODES. MAXIMUM RECOMMENDED WIRE SIZE IS 14 AWG.
Remove the two screws retaining the cover and cover gasket. Two
cast-in knockouts for 1/2 conduit are located on the side and
back of enclosure. These can easily be knocked out by placing the
blade of a screwdriver in the groove and tapping sharply with a
hammer. A 1/2 NPT conduit connection is also provided on
the left hand side of the enclosure. The three switch terminals
are clearly labeled common, normally open and normally
closed”. For switches supplied with leadwires, the following color
coding applies:

GENERAL
BEFORE INSTALLING, CHECK THE SENSOR MODEL SELECTED
FOR COMPATIBILITY TO THE PROCESS MEDIA IN CONTACT WITH
THE SENSOR AND WETTED PARTS.
The H100 and H100K differential pressure switches are activated when
a bellows, diaphragm or piston sensor responds to a pressure change.
This response, at a pre-determined set point, actuates a single snap-
acting switch, converting the pressure signal into an electrical signal.
Control set point may be varied by turning the internal adjustment hex.
(See Adjustment -PART II).
PROOF PRESSURE* LIMITS STATED IN THE LITERATURE AND ON
NAMEPLATES MUST NEVER BE EXCEEDED, EVEN BY SURGES
IN THE SYSTEM. OCCASIONAL OPERATION OF UNIT UP TO
PROOF PRESSURE IS ACCEPTABLE (E.G., START-UP, TESTING).
CONTINUOUS OPERATION SHOULD NOT EXCEED THE DESIGNATED OVER
RANGE PRESSURE.
*Proof Pressure
The maximum pressure to which a pressure sensor may be occasionally
subjected, which causes no permanent damage (e.g., start-up, testing).
The unit may require re-gapping.
Tools Needed
Adjustable Wrench
Screwdriver
Hammer (for alternate wire knockouts)
MOUNTING
INSTALL UNIT WHERE SHOCK, VIBRATION AND TEMPERATURE
FLUCTUATIONS ARE MINIMAL. ORIENT UNIT SO THAT MOIS-
TURE IS PREVENTED FROM ENTERING THE ENCLOSURE. IF
UNIT IS BEING INSTALLED WHERE HEAVY CONDENSATION IS EXPECTED,
VERTICAL MOUNTING (PRESSURE CONNECTION DOWN) IS REQUIRED. DO
NOT MOUNT IN AMBIENT TEMPERATURES EXCEEDING PUBLISHED LIMITS.
Controls may be mounted and operated in any
position. They may be surface mounted via the two mounting ears on
either side of the enclosure, or directly to a rigid pipe by using the pres-
