Types C100 and F100
Remove cover. Switch has a hex screw adjust-
ment inside enclosure. If switch transfer point
differs from actual temperature, adjust setting.
To raise the temperature setting, turn the hex in
(clockwise), and to lower the setting turn the
screw out (counterclockwise). When making
adjustments, do not exceed the maximum
temperature rating on nameplate.
Types B100 and E100 (with reference dial)
Controls are factory calibrated for maximum
accuracy at the midpoint of the scale.
To re-calibrate, turn dial to desired set point. If
the actual temperature and set point tempera -
ture do not agree, turn adjustment screw clock-
wise to raise and counterclockwise to lower
temperature setting.

REPLACEMENT PARTS AND PROCE -
DURES. ALWAYS DISCONNECT SUP-
PLY CIRCUITS BEFORE REMOVING COVER.
REPLACEMENT OF SWITCHES
1. Remove cover, switch mounting screws,
switch and insulator.
2. Disconnect switch wires at switch terminal.
3. Wire new switch per wiring instructions.
4. Mount switch and insulator inside enclosure
and re-calibrate per PART II.
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 max temperature lim -
its stated in literature and on nameplates must never be exceeded,
even by surges in the system. Operation of the unit up to proof pressure
or max temperature is acceptable on a limited basis (i.e.start-up, test-
ing) but continuous operation must be restricted to the designated
adjustable range. Excessive cycling at proof pressure or maximum tem -
perature 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 dangerous runaway condi-
tion could result.
• The adjustable range must be selected so that incorrect,
inadvertent or malicious setting at any range point can not 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.
• 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. 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.
• Use only factory authorized replacement parts and procedures.
• Do not mount unit in ambient temp. exceeding published limits.
• For remote mounted temperature units, capillary lengths beyond
10 feet can increase chance of error, and may require
re-calibration of set point and indication.
LIMITED WARRANTY
UE warrants that the product thereby purchased is, upon delivery, free
from defects in material and workmanship and that any such product
which is found to be defective in such workmanship or material will be
repaired or replaced by UE (F.O.B. UE); provided, however, that this
warranty applies only to equipment found to be so defective within a
period of 12 months after installation by buyer but not to exceed 18
months after delivery by the seller.
Except for the limited warranty of repair
and replacement stated above, UE disclaims all warranties whatsoever with
respect to the product, including all implied warranties of merchantability or fit-
ness for any

LIABILITY LIMITATION
The sole and exclusive remedy of buyer for any liability or seller
for any claim, including incurred in connection with (I) breach of any
warranty whatsoever expressed or implied, (II) a breach of contract,
(III) a negligent act or acts (or negligent failure to act) committed by
seller, or (IV) an act for which strict liability will be imputed to seller,
is limited to the limited warranty or repair and replacement stated
herein.
In no event shall the seller be liable for any special,
indirect, consequential or other damages of a like general nature, including,
without limitation, loss of profits or production, or loss or expenses of any nature
incurred by any third party.
