Three-Year Limited Warranty
System Sensor warrants its enclosed pressure switch to be free from de-
fects in materials and workmanship under normal use and service for a
period of three years from date of manufacture. System Sensor makes no
other express warranty for this pressure switch. No agent, representative,
dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation
of this Warranty shall be limited to the repair or replacement of any part of
the pressure switch which is found to be defective in materials or work-
manship under normal use and service during the three year period com-
mencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number,
send defective units postage prepaid to: System Sensor, Repair Depart-
ment, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to repair or replace units which are
found to be defective because of damage, unreasonable use, modifica-
tions, or alterations occurring after the date of manufacture. In no case
shall the Company be liable for any consequential or incidental damages
for breach of this or any other Warranty, expressed or implied whatsoever,
even if the loss or damage is caused by the Company’s negligence or fault.
Some states do not allow the exclusion or limitation of incidental or conse-
quential damages, so the above limitation or exclusion may not apply to
you. This Warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
• Electrical ratings stated in literature and on name-
plates should not be exceeded.
• Overload on switch can cause failure on the first
cycle. Always wire devices according to national and
local electrical codes.
• Install units away from shock and vibration. Proper
electrical fittings should be used to prevent moisture
from entering the enclosure via the conduit.
• Test all devices for proper operation after initial instal-
lation. Perform preventive maintenance and periodic
testing as required by the applicable NFPA standards
but not less than bi-monthly.
• Install a back-up control for all critical applications
where control failure could endanger life or property.
A backup control to serve as a high or low limit con-
trol is especially recommended for applications where
a runaway condition could result.
• Do not mount unit where ambient temperatures will
exceed published limits.
• Avoid impact or mechanical loading.
