Installation Instructions

Piping

NOTICE

RISK OF EQUIPMENT DAMAGE

•

Do not install in open systems using substantial make-up water.

• Follow proper water treatment practices and system procedures.

Failure to follow these instructio damage.

These valves must be piped according to the water ﬂow diagram. Two-Way valve ﬂow should go A to AB. Three-way

valves should be applied only as mixing valves (see diagram).

Best Practice Guidelines

It is recommended to ﬁt a strainer upstream of the valve to increase reliability and to follow water treatment guidelines as detailed in VDI 2035.

Recommendations

The pipework system should be ﬂushed prior to the operation.

Mounting

The valves can be mounted in horizontal or vertical piping. When installed in horizontal piping, the actuator must be above the valve body. It can be tilted left or right but it must not be tilted below 90° from vertical.

Installation Notes

• It is the responsibility of the installer or product speciﬁer to verify media compatibility of the valves construction materials with the supplier of water treatment/heat transfer solution.

• Conﬁrm there is no overhead water source that may drip onto valve actuator.

• In normal service, some condensation may occur on or around the valve. A drip pan may be necessary or the valve body may be insulated.

• Do not cover the actuator or obstruct the manual operator lever.

• Reference product label and Product Datasheet F-27895 for additional product speciﬁcations.

Installing the Actuator on the Valve Body for M22xxxx Unit

1. Turn the valve stem so that the slot on the top of the stem is pointing towards the large keyed post.

2. Insert the allen wrench into the manual crank shaft on the top of the actuator. Crank eight turns in the direction indicated on the label. In the last turn, align the indicator notch to the opening in the crankshaft. Press the button around manual crankshaft to lock in place. Remove and replace allen wrench in cover slot.

3. Align the valve body with the actuator to ensure the stem lines up with the large stem hole and the large keyed post lines up with the post hole on the bottom of the actuator.

4. Press the valve and actuator together to assemble.

5. The ﬁrst time the valve is operated electrically, the manual operating lever of the actuator will move to the automatic position. The manual operating lever can be used to allow ﬂushing of the system after installation.

Removing the Actuator

NOTICE

RISK OF EQUIPMENT DAMAGE

Do not use the valve body to manually open the actuator.

•

Failure to follow this instruction the actuator.

Press and hold the valve release lever inward, towards the valve.

2. Lift the actuator from the valve.

Checkout

Make sure the valve stem rotates freely before and after installing the actuator. If the stem does not operate freely it may indicate that the stem was damaged and may require that the valve be replaced. After the piping is under pressure, check the valve body and the connections for leaks. After the valve and actuator are installed, power the actuator and check the operation by varying the control signal. On spring return models, the valve should return to its normal position when power is removed.

will result in damage to

Installing the Valve Body

1. Apply PTFE tape to the male pipe thread.

2. Hand screw the pipe into the valve, turning it as far as it will go.

3. Use a wrench to fully tighten the valve to the pipe. Do not over tighten or strip the threads.

Installing the Actuator on the Valve Body for M21xxxx Unit

1. Turn the valve stem so the slot on top of the stem is pointing towards the large keyed post.

2. Align the valve body with the actuator to ensure the stem lines up with the large stem hole and the large keyed post lines up with the post hole on the bottom of the actuator.

3. Press the valve and actuator together to assemble.

Theory of Operation

When powered, the actuator moves to the desired position, winding the spring return system. When power is removed the spring returns the actuator to the normal position. This series of two-position spring return valve assemblies can be purchased with an optional built-in auxiliary SPDT end switch for interfacing or signaling; for example, zone pump burner control. The auxiliary switch is designed for contact closure after the valve is more than 50% open. Do not exceed the published switch electrical ratings. The manual override lever is designed to manually position the actuator to install on the valve or to manually position the valve. Turning the allen wrench in the manual crankshaft while power is applied or in the opposite direction as shown on the label will cause permanent damage. Use only the allen wrench provided with a maximum torque of 10 in-lb.
