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-

applicable.
Tools Needed
5/8” Open End Wrench
SOME MODELS HAVE A TWO-PIECE, ADJUSTABLE
PLUNGER. THIS FEATURE IS CHARACTERIZED BY A 3/16” HEX
HEAD SCREW INSTALLED IN THE 1/4” HEX PLUNGER. THE
LENGTH OF THIS ASSEMBLY IS ADJUSTED AT OUR FACTORY AND IS CRITI-
CAL TO THE FUNCTION OF THE CONTROL.
H100 and H100K
Remove pressure switch cover. Loosen Phillips screw adjustment lock.
Adjust set point by turning 5/8” hex adjustment screw clockwise (in) to
raise set point, or counter clockwise (out) to lower set point. Tension on
adjustment screw can be increased by tightening adjustment lock onto
it. (See diagram 1). Controls include uncalibrated reference scales for
high, low or mid range settings.
Adjustable Differential Models
Model 15623 and control types with option code 1519 incorporate
a snap switch with internal adjustment wheel. Turning this wheel
raises or lowers the pressure rise set point. The fall set point remains
constant. Consult factory for additional information.
Manual Reset Button
Control types with option code 1530 incorporate a snap switch which
when actuated, remains actuated until the pressure drops sufficiently
to allow the reset button (located on top of the control) to be manually
depressed to reset the switch.
Gapping
1) Loosen adjustment lock.
2) Turn 5/8” hex adjustment screw in, to approximately mid range.
This puts a load on the sensor and exposes the plunger flats. Using
a 1/4” wrench on the plunger and a 3/16” wrench on the plunger hex
screw, turn hex screw out from plunger until switch actuates. If switch
is already actuated, turn plunger hex screw in, until switch deactuates.
Turn hex screw in from this point. (See chart 1 for Flats and approxi-
mate Gap.)
3) Check set point according to Part II Adjustments.
4) Connect wires and replace cover securely.

RECOMMENDED PRACTICES AND WARNINGS
United Electric Controls Company recommends careful consideration of the following factors when
specifying and installing UE pressure and temperature units. Before installing a unit, the Installation and
Maintenance instructions provided with unit must be read and understood.
• To avoid damaging unit, proof pressure and maximum temperature limits stated in literature and on
nameplates must never be exceeded, even by surges in the system. Operation of the unit up to
maximum temperature is acceptable on a limited basis (i.e., start-up, testing) but continuous operation
must be restricted to the designated adjustable range. Excessive cycling at maximum temperature limits
could reduce sensor life.
• A back-up unit is necessary for applications where damage to a primary unit could endanger life,
limb or property. A high or low limit switch is necessary for applications where a dangerous runaway
condition could result.
• The adjustable range must be selected so that incorrect, inadvertent or malicious setting at any
range point cannot result in an unsafe system condition.
• Install unit where shock, vibration and ambient temperature fluctuations will not damage unit or affect
operation. Orient unit so that moisture does not enter the enclosure via the electrical connection.
When appropriate, this entry point should be sealed to prevent moisture entry.
• Unit must not be altered or modified after shipment. Consult UE if modification is necessary.
• Monitor operation to observe warning signs of possible damage to unit, such as drift in set point or
faulty display. Check unit immediately.
• Preventative maintenance and periodic testing is necessary for critical applications where damage
could endanger property or personnel.
• For all applications, a factory set unit should be tested before use.
• Electrical ratings stated in literature and on nameplate must not be exceeded. Overload on a switch
can cause damage, even on the first cycle. Wire unit according to local and national electrical codes,
using wire size recommended in installation sheet.
• Do not mount unit in ambient temp. exceeding published limits.

* Over Range Pressure: The maximum pressure that may be applied continuously without causing damage and maintaining set point repeatability.
** Proof Pressure: The maximum pressure to which a pressure sensor may be occasionally subjected, which causes no permanent damage. The unit may require calibration (e.g., start-up, testing).
Deadband Note: Models 190-194, 490-494 are expressed as the lower 75% and top 25% of the range span because of the operating characteristics of the diaphragm sensor and switch.
