Notice to the Installer
• Read this entire instruction sheet before installing to ensure proper installation.
• Installation must comply with local codes and ordinances.
Pressurized plumbing fixtures shall be installed in accordance with manufacturer’s recommendations. The supply piping to these devices shall
be securely anchored to the building structure to prevent installed device from moving unnecessarily when operated by the user. Care shall be
exercised when installing the device to prevent marring the exposed surface.
NOTE: The information in this manual is subject to change without notice.
Please leave this manual with the facility manager after completing the faucet installation. This document contains information necessary for
routine maintenance and servicing.
NOTE: Before installation, turn off water supplies to existing faucet and remove faucet if replacing. Clean faucet basin and clear away debris.
Flush all supply lines before connecting to faucet. Failure to do so can result in debris clogging the inlets and/or cartridges.
NOTE: Before installing a replacement cartridge flush lines completely.
Installation Instructions
1. At the time of installation, it is recommended that all pipes to the pedal box be thoroughly flushed. Failure to do so may result in foreign matter such
as line sediment or plumbing compounds clogging the by-pass of the dashpot or embedding in the seat and impairing operation of the cartridge.
2. Chicago Faucets pedal boxes are fully assembled at the factory and ready for operation. Installation is simply a matter of securely mounting the
product and connecting the water supplies.
3. Remove contents from packaging and read instructions thoroughly before installation.
4. Chicago Faucets pedal boxes are available in wall, floor, and shelf mount configurations. These are heavy commercial faucets and must be
mounted securely to a solid surface to prevent movement. They are all designed with a 1/4˝ diameter through-hole that has a countersunk
chamfer to accept common wood screws. It is strongly recommended that a 2˝ x 4˝ wood backing be used to provide a solid surface for the
wood screws to secure the fitting to the mounting surface.
5. Once the pedal box is securely mounted, the water supplies can be connected. All pedal boxes are designed with 1/2˝ NPT threaded female
inlets as a standard supply connection. For the outlet connections the 628 and 806 also have a 1/2˝ NPT threaded female outlet, while the 625
and 834 are designed with a 3/8˝ NPT threaded female outlet.
6. Once all inlet and outlet supplies are securely connected, the water can be turned on to check for leaks. Activate one or both pedals, depending
on the design, several times to insure that the product is operating properly.
7. The pedals on all pedal boxes must have sufficient clearance between the bottom of the pedal and the floor so that the cartridge can be
depressed fully. The 806 and 834 models have an additional pedal height adjustment screw, due to their long pedals, to aid in installation. Refer
to the specification sheet for your specific model for dimensional requirements.
General Maintenance
1. Your Chicago Faucets foot pedal valve is chrome plated to protect the brass construction material. The same plating is used for our rough (RCF)
or polished (CP) surfaces. With either finish, mild soap and water or mild cleaners approved for chrome plated surfaces should only be used. Do
not use products with acid ingredients. Using acid based products can cause discoloration or other damage to the finish.
2. Chicago Faucets pedal boxes are supplied with one of two cartridge types. The standard version activates when your foot depresses the pedal
and deactivates immediately when your foot leaves the pedal. The alternative closing feature is the “SLO” or slow closing cartridges. With
these cartridges the same method is used to activate the water, but when you remove your foot the water will continue to dispense for a predetermined period of time. The timing duration can be set to run up to 20 seconds. Please refer to instructions below.
3. Routine maintenance may be required periodically after installation to insure that your pedal box continues to operate properly.
How to Repair a NAIAD Push Button
1. Loosen (319-003) Cap Nut with combination or flat wrench, remove cartridge. In some cases, the dashpot may remain in the body. When this
occurs, reach in the body cavity with your finger to remove.
2. Insert pin wrench (244-025) or 1/8˝ diameter pin through hole to keep stem from turning while removing or tightening (333-097) Stem Nut.
3. If leakage is occurring through spout, remove and replace (1-027) Seat or (244-006) Seat Washer. Also inspect (333-040) Cup Washer.
If leakage is around button assembly, remove button and stem sub-assembly from (319-003) Cap Nut and (433-042) or (433-046- one outlet
hole) Sleeve. Clean stem thoroughly and lubricate top half with light grease. Replace the packing arrangement of (2)-(319-140) O-Rings and
(1)-(319-035) Leather Washer.
4. To reassemble, place stem sub-assembly into (319-003) Cap Nut and (433-042) or (433-046) Sleeve. Then at lower end of cartridge starting
with (1-027) Seat, put remaining parts on, in order, as indicated in diagram below.

How to Adjust a NAIAD Cartridge Using a 333-073K Dashpot
1. On (333-073K) Dashpot used on pedal boxes where an adjustable closing feature is desired, this dashpot uses a black 333-027 Felt Washer,
333-028 Brass Washer and 333-052 Stainless Steel Nut on the lower end of dashpot, in lieu of the hole on other dashpots. Adjustment is
made by tightening the nut to increase the running time, or loosening nut to decrease running time.
2. After a period of service, variation may be noted in the flow time from the original setting. This indicates foreign matter has plugged the felt
washer and cleaning or replacing the washer is required, or (333-040) Cup Washer needs to be replaced.
