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.

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.

Note: This is a control system which must be cleaned and maintained regularly (see Maintenance Guide and Record card included with valve shipment).

Retaining Ring

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.

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 Piping Method

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.

Note: This is a control system which must be cleaned and maintained regularly (see Maintenance Guide and Record card included with valve shipment).

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 Sto p."
