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.

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.

C)Time is changed by rotating plastic serrated adjustment nut with a pair of pliers. Raising nut (counter clockwise) shortens time, lowering nut (clockwise) lengthens time.
(Figure 4)
D)After each adjustment, replace handle and check cycle time.

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.
