Installation, Operation and Maintenance Guide

G3600 Series Thermostatic Mixing Valves

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.

Installation

G3600 G3650

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: Please provide valve serial number (stamped on cover of valve) when ordering parts.

Installation, Operation and Maintenance Guide

G3600 Series Thermostatic Mixing Valves

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.

Adjustment And Service

Troubleshooting

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.

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).

To reset adjustable high temperature limit stop:

SEE PAGE 5 FOR COMPLETE PARTS BREAKDOWN AND PARTS KITS. If installed on a circulated hot water system, make certain the

valve is piped according to Guardian Equipment Required Methods of Piping (see page 3).

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.

Installation, Operation and Maintenance Guide

G3600 Series Thermostatic Mixing Valves

METHOD #1: Required when hot water is to be circulated to a thermostatic mixing valve which is a substantial distance from the

hot water source.

G3600 G3650

• Cycle redundant thermostat valve by, limit stop (see page

2) and setting the primary thermostatic mixing valve to full

hot. (G3600 only)

• Open eye wash and check to be sure outlet temperature

does not climb above 90°F (32°C).

• Turn primary thermostatic valve to full cold and wait ten

seconds.

• Turn primary thermostatic valve to full hot and wait ten

seconds.

• Check to be sure outlet temperature does not climb above

90°F (32°C).

• Turn primary thermostatic mixing valve to full cold and wait

ten seconds.

• Set primary thermostatic mixing valve to the desired

temperature, adjust limit stop (see page 2) and close eye/face

wash.

This unit must be cycled each time the emergency equipment is checked. See ANSI Z358.1, Maintenance and Training section:

Note: The G3650 Redundant Thermostatic Mixing Valve has been

factory set at 85°F (29°C). This set point can be field adjusted with

a 3/8” wrench (see diagram). “Clockwise” direction will increase

temperature. Maximum set point is 90°F (32°C).

Instructions for Dismantling Valve

Turn o hot and cold supplies to this valve. Remove four cover

screws MU-2C, lift o cover and thermostat group 6810 (g. 1).

After installing new parts, it will be necessary to reset Pointer to

obtain correct temperature range from Cold to Hot. See page 2

instructions “TO RESET ADJUSTABLE HIGH TEMPERATURE LIMIT

STOP.”

To Clean Port Sleeve Assembly:

To clean port sleeve assembly TAG-1M (g. 2.): Remove base

stud TA-5. Back o port sleeve nut 3402 as far as it will go into

base. Slide TAG-1M port sleeve assembly toward port sleeve

nut and lift out of valve base. Clean part TAG-1M with a soft

cloth; DO NOT use abrasives such as emery cloth or sandpaper.

After cleaning, wash parts in clean water and reassemble in

valve base. When reassembling port sleeve assembly BE SURE

TO INSTALL WITH SHORT SLOT END IN BASE AND LONG SLOT

END AT PORT SLEEVE NUT. Locate one set of port slots facing

directly toward front of the valve. Tighten port sleeve nut 3402

just enough to hold port sleeve in place, (do not cramp or dis-

tort port sleeve by exerting excess size pressure when tighten-

ing port sleeve nut).

To Clean Thermostat Group:

To clean thermostat group 6810 (DWG 1.), remove handle

68240 by loosening lock screw and pull o. Remove stop re-

taining ring MU-13D and stop 6820. Remove thermostat group

by pushing rod through cover. BE CAREFUL NOT TO PULL COILS

OUT OF SHAPE. If deposit has collected on thermostat coil,

clean it o with a brush in cleaning solution and wash well

before reassembly. Cleaning solution should be non-corrosive

and grit free. To reassemble: be sure, port sleeve assembly is

in place and is working freely from side to side. Reinstall base

stud TA-5, then place thermostat group 6810 on base stud and

BE SURE DRIVING BALL ON PORT SLEEVE ASSEMBLY TAG-1M IS

INSERTED IN HOLE ON LOWER COIL BRACKET (DWG 3.) Move

thermostat back and forth to be sure all parts are free. Replace

cover on valve base, install the four cover screws, and turn on

hot and cold water supplies. See instructions below “To Reset

High Temperature Limit Stop” to properly reset limit stop.

After installation, adjustment, and cleaning, always check the

temperature of the valve when turned to full HOT per the

warning on the front page, using a thermometer. Also check

and if necessary adjust the temperature of the hot water

source. EXCESSIVELY HOT WATER (OVER 90ºF) IS DANGEROUS

AND MAY CAUSE SCALDING!!
