APPLICATION

These valves consist of an actuator motor and valve assembly for controlling the flow of hot and/or cold water. The V8043A provides two-position, straightthrough control of supply water. The valves are designed for use with fan coil and other units requiring quiet, compact water valves. The V8043E and V8043F also control supply water for baseboard radiators and convectors.

INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to

follow them could damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and

on the product to make sure the product is suitable for your application.

3. Installer must be a trained, experienced service

technician.

4. After installation is complete, check out product

operation as provided in these instructions.

1. Disconnect power supply before connecting wiring to prevent electrical shock of equipment damage.

2. Normally it is not necessary to remove the powerhead from the valve body during installation. If the valve must be disassembled, be certain that it is reassembled with the water flow in the direction of the arrow. Reversal of the powerhead will result in damage to the gear train.

3. On 24V systems, never jumper the valve coil terminals even temporarily. This may burn out the heat anticipator in the thermostat.

IMPORTANT

Use this valve in hydronic heating systems which do not contain dissolved oxygen in the system water. The dissolved oxygen, which is found in systems that have a frequent source of m akeu p wa ter, c ause s the rubb er pl ug i nsid e the valve to deteriorate and eventually fail.

LOCATION

Install the valve in an area with adequate clearance to:

— move the manual opening lever on the side of

the powerhead; — remove the powerhead cover; — wire the powerhead; — replace the powerhead motor.

The valve location should be in an area where the temperature does not exceed the maximum valve operating temperature as shown in Specifications.

MOUNTING

The valve can be mounted in any position on a vertical line. If the valve is mounted horizontally; the powerhead must be even with or above the center line of the piping. Make sure that enough room is provided above the powerhead to remove the cover for servicing.

Fig. 3. Mounting positions.

Mount the valve directly in the tube or pipe. Make sure that the flow through the valve is in the direction indicated by the arrow stamped on the valve body.

Read and understand all instructions for installing the press connection. Failure to follow all instructions may result in extensive property damage, serious injury or death.

3. Check seal for correct fit. Do not use oils or

lubricants.

4. Mark proper insertion depth as shown in Table 2.

Improper insertion depth may result in improper seal.

5. While turning slightly, slide press fitting onto

tubing to the marked depth.

NOTE: End of tubing must contact stop.

6. Insert appropriate jaw into the pressing tool and

push in, holding pin until it locks in place.

7. Open the jaw and place at right angles on the

fitting. Visually check insertion depth using mark on tubing.

8. Start the pressing process and hold the trigger

until the jaw has engaged the fitting.

9. After pressing, the jaw can be opened again.

10. Leak Testing with Smart Connect®:

Unpressed connections are located by pressurizing the system with air or water. When testing with water the proper pressure range is 15 psi to 85 psi maximum. Leak testing with air can be dangerous at high pressures. When testing with compressed air the proper pressure range is ½ psi to 45 psi maximum. Following a successful leak test, the system may be pressure tested up to 200 psi with air, or up to 600 psi with water, if required by local code requirements or project specifications.

WIRING

Disconnect the power supply before connecting wiring to prevent electrical shock or equipment damage.

All wiring must comply with local codes and ordinances. Connections to the individual valves are shown in Fig. 5-6.
