Please include a note describing the malfunction and suspected cause
of failure. The Company shall not be obligated to replace units which
are found to be defective because of damage, unreasonable use, modi-
fications, 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 limita-
tion of incidental or consequential 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.

the obligations or limitations of this Warranty. The Company’s obliga-
tion of this Warranty shall be limited to the replacement of any part of
the product which is found to be defective in materials or workman-
ship under normal use and service during the three year period com-
mencing with the date of manufacture. After phoning System Sensor’s

Switch Enclosure Replacement
1. Remove the three screws holding the switch enclosure.
2. Pull gently on the switch enclosure and rock slightly to
disengage the switch buttons from the timer stop.
3. Install the replacement switch enclosure using a similar
rocking action to depress the switch buttons. Do not
turn the timer stop or shaft more than 15 degrees while
replacing the switch enclosure. Check the position of
the timer stop per Figure 2.
4. Slide the switch enclosure toward the delay mechanism
until the vertical alignment boss on the plate seats into
the alignment groove one corner of the switch enclo-
sure. (Only one will engage.) Exert pressure on the
switch enclosure holding it seated flat and pushed to-
ward the delay mechanism while replacing the three
retaining screws. Seat firmly using approximately 6 in-
lbs. of torque.
System Check
1. With the dial set on zero, actuate the lever arm forward
and back checking for smooth operation of the switch
mechanism. The lever arm should operate freely with no
obstruction. The switches should activate when the arm
is moved forward and reset when the arm is released.
2. With a continuity meter installed between the (COM)
and (B) terminals on one of the switches, the following
conditions should occur:
Condition COM to B Circuit
Normal or non-flow Open circuit
Lever actuated or water-
flow in pipe (10 gpm) Closed circuit
3. Turn the dial to the desired delay setting and time the
response of the system to waterflow conditions as nor-
mally done on routine system tests.
4. Insure that the system returns to the non-alarm condi-
tion after the flow in the system is discontinued.
5. Replace the cover with the two security screws and
wrench (not supplied).
