TO INSTALL:
1. Turn off water at the supply stop(s).
2. Remove existing handles and units. Follow the chart on the
first page (Figure 1 ) to insure that the correct parts are being
used.
3. Flush supply lines to remove chips and dirt which can
become lodged in the seat washer and cause the faucet to
run on.
4. Inspect the seating surface inside the body and clean
thoroughly. If the seat is damaged (pitted or nicked) or if
heavy lime build-up has occurred, contact your nearest
Chicago Faucet representative for assistance. Failure to clean
up old seating surfaces can damage the new MVP™
cartridge and cause a dripping or
run-on situation. (Figure 2)
TROUBLE SHOOTING:
Accumulation of lime and/or dirt in
the cartridge can result in either short
or excessively long cycles. If either
occurs, remove cartridge and wash
with soap and water or a mild
solution of vinegar and water. If
continued problems are experienced,
contact your local representative for assistance.
5. Insert the filter into the body and make sure it is completely
down and in place against the body seat. Then insert the
cartridge into the body. Make sure the cartridge is also
completely down and in place against the body seat
(Figure 3).

NOTE:
This cartridge is designed to be
used with the large filter enclosed. It is
possible when retrofitting existing fittings
that this filter cannot be used (especially
in type I and II fittings shown on Page
2). If no water flow occurs after Step
7, shut the stop off and disassemble
fitting to remove the larger drop-in style
filter. Replace it as shown with the small
filter enclosed.
IMPORTANT: NEVER USE BOTH FILTERS TOGETHER ON
THE SAME FITTING
6. Place the white cap sealing gasket into the actuator
assembly and screw the actuator assembly onto the body.
Tighten the actuator assembly onto the body to
approximately 20 ft. Ibs., (Hand tighten and give the actuator
assembly a 1/2 to 1 full turn with a wrench). (Figure 3)
7. Turn the water back on at the supply stop(s).
NOTE:
If leak occurs at cap gasket, remove gasket and inspect
it for damage and replace it if necessary. If the gasket is in good
condition, inspect the body surface for scratches or nicks and
clean up the surface by reaming if necessary.
TIMING ADJUSTMENT
:
These instructions are for the user to adjust the faucet to provide
a flow rate to meet the American Disability Act (ADA) regulations
which require 10 seconds running time for the water flow. For
ADA compliance follow these procedures:
NOTE:
Timing must be checked with the handle in place.
A) Purge the valve of air by pushing it completely open 4-8
times rapidly and then check the timing cycle .
B) Remove the handle with a 3/32” hex wrench.

E) Once cycle time is satisfactory, lock handle in place making
sure set screw is securely fastened on groove in stem.
(Figure 5) If a type 665 handle is used, remember to insert the
colored index button.
NOTE: A variation from cycle to cycle should be expected. It is
best to wait until hot water is available and the building as in use
before making final adjustments.
Some new installations may produce a slight closing noise. This
is normally the result of air trapped in the unit and the noise will
dissipate over time.
