IMPORTANT!
Read this entire installation manual to ensure proper installation.
When finished with the installation, file this manual with the owner or
maintenance department. Compliance and conformity to local codes and
ordinances is the responsibility of the installer.
Separate parts from packaging and make sure all parts are accounted
for before discarding packaging material. If any parts are missing, do not
begin installation until you obtain the missing parts.
Make sure that all water supply lines have been flushed and then
completely turned off before beginning installation. Debris in supply lines
can cause valves to malfunction.
Product warranties may be found under “Products” on our web site at

Cleaning and maintenance instructions for stainless steel
Material Description: Stainless steel is extremely durable, and maintenance is simple and inexpensive. Proper care, particularly
under corrosive conditions, is essential. Always start with the simplest solution and work your way toward the more complicated.
Routine cleaning: Daily or as often as needed use a solution of warm water and soap, detergent, or ammonia. Apply the cleaning
solution per the manufacturer’s instructions and always use a soft cloth or sponge to avoid damaging the finish.
Stubborn Stains: To remove stains from stainless steel use a stainless steel cleaner and polish such as Ball®stainless steel
cleaner or a soft abrasive. Always follow the manufacturer’s instructions and apply in the same direction as the polish lines.
CAUTION! Never use ordinary steel wool or steel brushes on stainless steel. Always use stainless steel wool
or stainless steel brushes.
Special Situations for Material
Fingerprints and Smears: To remove fingerprints or smears use a high quality stainless steel cleaner and polish in accordance
with the manufacturer’s instructions. Many of these products leave a protective coating that helps prevent future smears and
fingerprints.
Grease and Oil : To remove grease and oil use a quality commercial detergent or caustic cleaner. Apply in accordance to the
manufacturer’s instructions and in the direction of the polish lines.
Precautions: Avoid prolonged contact with chlorides (bleaches, salts), bromides (sanitizing agents), thiocyanates (pesticides,
photography chemicals, and some foods), and iodides on stainless steel equipment, especially if acid conditions exist.
CAUTION! Do not permit salty solutions to evaporate and dry on stainless steel.
The appearance of rust streaks on stainless steel leads to the belief that the stainless steel is rusting. Look for the actual source
of the rust in some iron or steel particles which may be touching, but not actually a part of the stainless steel structure.
NOTE: Strongly acidic or caustic cleaners may attack the steel, causing a reddish film to appear. The use of these
cleaners should be avoided.
Brand Names: Use of brand names is intended only to indicate a type of cleaner. This does not constitute an endorsement, nor
does the omission of any brand name cleaner imply its inadequacy. Many products named are regional in distribution, and can be
found in local supermarkets, department and hardware stores, or through your cleaning service. It is emphasized that all products
should be used in strict accordance with package instructions.

Problem Cause Solution
Valve will not shut
off. Timing mechanism is
clogged.
Clean and inspect timing mechanism:
1. If compressed air is available, blow water and debris from timer cover of timing
mechanism.
2. Turn adjusting screw out all the way. Clean and inspect screw and valve body.
3. Turn adjusting screw in to desired cycle time.
One or more
individual operating
stations fail to turn
on.
Water is not being
supplied to unit. Open all stops on mixing valve.
Water pressure is
over 80 PSI. Install a pressure reducing valve.
Failed diaphragm/
magnet assembly. Unscrew the valve clamp nut on valve. Remove valve cover. Gently press the diaphragm. The valve should activate. If not, replace the diaphragm/magnet assembly.
One or more
individual operating
stations turn off too
quickly or run too
long.
There is an air
leak. Check the valve assembly:
1. Check all tubing and fittings for proper assembly.
2. Tighten cap and nut on 1/8" tubing.
Pushbutton does
not work properly. Air volume may not be sufficient to
operate valve.
Check for leaks and lubricate U-cup:
1. Check all fittings for air leaks.
2. Disassemble pushbutton and lubricate U-cup seal (see pushbutton assembly
diagram on next page).
Water is dripping
from the
streamformers.
Debris has
accumulated
on valve seat or
orifices.
Clean and inspect valve seat:
1. Remove screws and disassemble metering valve.
2. Clean valve seat and inspect for deep gouges or scratches. Replace valve body if
necessary.
3. Remove any debris clogging off-center hole in rubber diaphragm.

External leaks. Damaged cartridge or O-rings. Replace cartridge with part number 269-1927
Improper water
temperature or

fluctuation.
Hot water supply is not 10° above desired set point. Increase hot water supply temperature
Valve temperature is not properly set. Adjust the temperature as shown on page 6, step 4.
Limited water flow. Dirt and debris have built up in the valve or strainer. 1. Check to make sure both hot and cold supplies are
connected to the Navigator mixing valve and that
they have water flow.
2. Remove cover and U-clip. Remove the cartridge
and clean the strainer. It is not required to grease
cartridge, however if desired, use silicone grease
only. Do not use grease on check valves.

Thermostatic Mixing Valve Troubleshooting
Before attempting to troubleshoot the valve or disassemble the components, check for the following
conditions:
• If stop valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no cross-
connections or leaking stop valves.
• Check the hot water heater output to make sure that it is at least 10° F above the set temperature.
Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen the valves after inspection
and repair is complete.
