G3600LF Series Thermostatic Mixing Valves
IMPORTANT: THESE SYSTEMS ARE DESIGNED TO PROVIDE MIXED WATER
FROM 60 TO 90°F (15 TO 32°C) FOR EMERGENCY EYE OR EYE/FACE WASH
APPLICATIONS ONLY IN ACCORDANCE WITH ASSE 1071.
Installation
1. Install valve in a location where it may be easily cleaned,
adjusted or repaired.
2. Inlets are clearly marked on valve body casting. Connect hot
water to inlet marked "HOT" and cold water to inlet marked
"COLD."
3. Included angle checkstops must be installed on both supply
lines (see above).
4. Use solder or pipe cement sparingly. Flush supply pipes
before connecting valve. Flush outlet pipe and valve once
valve is connected.
Maximum operating pressure is 125 PSI (860 KPA) for hot and cold
water. Maximum hot to cold water pressure dierential is 5%.
Note: Should piping be exposed to excessive hot or cold conditions,
it may be necessary to insulate piping to prevent freezing or scalding
water.
Note: Please provide valve serial number (stamped on cover of valve) when ordering parts.

G3600LF Series Thermostatic Mixing Valves
Adjustment and Service
Guardian Equipment thermostatic mixing valves may be easily
cleaned, adjusted and repaired. Servicing may be possible
without disconnecting valve.
Note: Thermostatic water mixing valves are regulating mechanisms which
must be regularly maintained to provide best performance. Local water quality
and usage conditions dictate cleaning frequency. (See Maintenance Guide and
Record card included with valve shipment and reference ANSI Z358.1)
1. Remove handle, retaining ring, loosen set screw, and remove stop.
2. Activate emergency xture.
3. Replace handle and adjust to reach desired maximum temperature.
Note: Temperatures above 90°F are not recommended. Consult a
medical advisor for correct temperature settings.
4. Replace stop such that it rests against the web on the left side of the
cover.
5. Tighten set screw and reassemble. Hold a thermometer under water
ow to verify maximum temperature has been set appropriately.
Then set desired operating temperature.
Troubleshooting
To Reset Adjustable High Temperature Limit Stop:
If installed on a circulated hot water system, verify the valve is piped according to Required Piping Method on page 3.
See page 5 for complete parts breakdown and parts kits.
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. EXCESSIVE
HOT WATER TEMPERATURE 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
135°F (57°C). IF THE INCOMING HOT
WATER TEMPERATURE IS HIGHER
THAN 135°F (57°C), 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.

Required when hot water must be circulated to a thermostatic mixing valve that is a substantial distance from the hot water
source. Recommended hot water inlet temperature is 135°F (57°C).
This unit must be cycled each time the emergency equipment is inspected (See ANSI Z358.1, Maintenance and Training section).
1. Set the thermostatic mixing valve to full hot.
2. Activate eye or eye/face wash and verify outlet temperature
does not exceed 90°F (32°C).
3. Turn thermostatic valve to full cold and wait ten seconds.
4. Turn thermostatic valve to full hot and wait ten seconds.
5. Verify outlet temperature does not exceed 90°F (32°C).
6. Turn thermostatic mixing valve to full cold and wait ten
seconds.
7. If necessary, adjust high temperature limit stop (see page 2).
Then set mixing valve to desired operating temperature and
deactivate emergency equipment.

To Dismantle Valve:
Turn o hot and cold water supplies to valve. Remove four
cover screws and remove cover and thermostat group. (Figure
1) After replacing parts, lockable dial must be reset to obtain
correct temperature range from Cold to Hot. (see "To Reset
Adjustable High Temperature Limit Stop" on page 2).
To Clean Port Sleeve Assembly:
Remove base stud (Figure 2). Twist port sleeve nut into valve
body, slide port sleeve assembly toward port sleeve nut, and
lift from valve body to clean. Clean with non-corrosive agent
and soft cloth. DO NOT USE ABRASIVES. Wash parts thoroughly
after cleaning and reassemble. Reinstall port sleeve assembly
with long slot end nearest port sleeve nut. Tighten port sleeve
nut to complete reassembly. DO NOT OVERTIGHTEN.
To Clean Thermostat Group:
Loosen set screw and remove handle (Figure 1). Remove
retaining ring and stop. Push rod through cover to remove
thermostat group. DO NOT PULL COILS OUT OF SHAPE. Use
brush and cleaning solution (non-corrosive and grit-free)
to remove any depost build-up from thermostat coil. Wash
thoroughly before reassembly.
Reassemble by reinstalling base stud, then place thermostat
group 6810 on base stud. PORT SLEEVE ASSEMBLY DRIVING
BALL MUST BE INSERTED INTO HOLE ON LOWER COIL
BRACKET(Figure 3). Verify thermostat moves back and forth.
Replace cover and screws and turn hot and cold water supplies
on. See page 2 "To Reset Adjustable High Temperature Limit
Stop."
Note: After installation, adjustment, and cleaning, always verify
valve temperature with thermometer when turned to full hot. If
necessary, adjust temperature of hot water source. EXCESSIVE
HOT WATER TEMPERATURE (OVER 90°F) IS DANGEROUS AND
MAY CAUSE SCALDING.
