Installation
1. Valve should be installed at a location where it can easily be
cleaned, adjusted or repaired.
2. The inlets are clearly marked on the valve body casting.
Connect the hot water into the inlet marked “HOT” and cold
water into the inlet marked “COLD.”
3. The checkstops furnished must be installed on both supply
lines as shown above.
4. Use solder or pipe cement sparingly. Supply pipes should
be flushed before the valve is connected. Flush outlet pipe
and valve as soon as it is connected.
Maximum Operating Pressure 125PSI (860 KPA) for Hot and Cold
Water. Maximum hot to cold water pressure differential is 5%.
Note: It may be necessary to recirculate the tempered water to the
face/eyewash should the piping be exposed to excessive hot or cold
conditions. Consult factory for proper piping.
Note: this is a control system which must be cleaned and maintained on a regular basis (see maintenance guide and record MGRG-1000).
IMPORTANT: THESE SYSTEMS ARE DESIGNED TO
PROVIDE MIXED WATER FROM 60 TO 90°F (15 TO
32°C) FOR EMERGENCY SHOWER APPLICATIONS
ONLY. CALL GUARDIAN EQUIPMENT FOR SYSTEMS
DESIGNED TO OPERATE AT TEMPERATURES
OUTSIDE OF THIS RANGE.

Adjustment And Service
Installation, Operation and Maintenance Guide
G3600 Series Thermostatic Mixing Valves
Guardian Equipment Thermostatic Water Mixing Valves are
simple in design and may be easily cleaned, adjusted and
repaired. If the installation is accessible, servicing may be
completed without disconnecting the valve.
To reset adjustable high temperature limit stop:
HANDLE
68240
1. Remove 68240 handle, MU-13D retaining ring and loosen
6910 set screw, and remove 6820 stop.
2. Turn emergency fixture on.
3. Replace handle on stem and turn stem until desired
maximum temperature is reached.
4. Replace stop so it rests against the web on the LEFT side
of the cover.
5. Set operating temperature, tighten 6910 set screw and
reassemble.
Note: Thermostatic Water Mixing Valves are REGULATING mechanisms,
which must be regularly maintained to provide best performance.
Frequency of cleaning depends on quality of local water conditions
and usage. (See Maintenance Guide and Record MGRG-1000 and ANSI
Z358.1).
WARNING: THIS THERMOSTATIC MIXING VALVE
HAS AN ADJUSTABLE HIGH TEMPERATURE LIMIT
STOP WHICH MUST BE CHECKED. IF TEMPERATURE
IS TOO HIGH, THE INSTALLER MUST RESET
THIS STOP IMMEDIATELY. ALWAYS CHECK THE
TEMPERATURE OF THE MIXED WATER WHEN
THE LEVER HANDLE IS TURNED TO FULL HOT.
EXCESSIVELY HOT WATER IS DANGEROUS AND
MAY CAUSE SCALDING!
THE HIGH TEMPERATURE LIMIT STOP IS FACTORY
SET AT APPROXIMATELY 90°F (32°C) WITH AN
INCOMING HOT WATER SUPPLY TEMPERATURE
OF 140°F (60°C). IF THE INCOMING HOT WATER
ON THE JOB IS HIGHER THAN 140°F, THE VALVE
WHEN TURNED TO FULL HOT WILL DELIVER
WATER IN EXCESS OF 90°F (32°C) AND THE HIGH
TEMPERATURE LIMIT STOP MUST BE RESET BY THE
INSTALLER.
