Step 2ÐWiring

To prevent personal injury or possible equipment damage, disconnect the power supply before routing wire.

All wiring must comply with local, state, and national codes.

insulate over the actuator assembly. Make sure insulation does not interfere with operation of actuator.

Before insulating the ductwork, check for proper damper opera- tion. Apply 24vac between COM and OPN to open the damper and COM and CLS to close the damper. (See Fig. 3.) The damper will modulate counter-clockwise to open and clockwise to close.

NOTE: Use No. 18 AWG color-coded, insulated (35°C min) wire. If thermostats are to be located more than 100 ft from the WeatherMaker Two-Zone Center as measured along the control voltage wires, use 16 AWG colored-coded wires to avoid exces- sive voltage drop. All wiring is run back to the WeatherMaker Two-Zone Center.

Step 3ÐInstall WeatherMaker Two-Zone

→ NOTE: WeatherMaker Two-Zone is approved for indoor use

only and should never be installed with any of its components

exposed to the elements. Do not mount WeatherMaker Two-Zone

Center where it will be accessible to children. Do not locate the

center in areas of the home that are noise sensitive since relays are

energized and de-energized during operation and may be an

annoyance. Install WeatherMaker Two-Zone in an area with a

temperature range between 32°F and 150°F.

Install WeatherMaker Two-Zone center in a vertical position.

Locate in an area that is easily accessible in case servicing should

be required.

Step 4ÐInstall Zone Dampers

IMPORTANT: If conditions exist for possible condensing, the motor must be positioned for adequate draining. (See Fig. 2.)

NOTE: If a multi-damper enabler is used to link dampers together, then add 5va per damper to the transformer power supply rating. Reference multi-damper enabler Installation Instructions.

Zone dampers may be installed in any direction.

Install dampers so the actuator is visible for inspection and accessible in the event it would ever need service. The black mark on the end of the damper shaft represents the position of the damper blade.

If in an emergency it becomes necessary to force a damper open manually, press in red quick blade release button with 1 hand and turn mounting hub to reposition the damper shaft. Release button to hold damper shaft in the new position.

To avoid noise and vibration, do not hard mount dampers to any solid structure such as joists.

ROUND METAL DUCTWORK

IMPORTANT: If application exists with all metal ductwork without insulation, flex connectors should be used on each end of the zone dampers to avoid noise and vibration.

1.Crimp end of branch duct.

2.Slip end of flex connector over zone damper and use self- tapping sheet metal screw to secure. (See Fig. 4.)

3.Properly seal joint using duct tape, mastic, or other approved method. Do not allow mastic to come in contact with actuator.

4.Insulate damper using 1-1/2-in. to 2-in. insulation. (Check your local codes.) (See Fig. 5.)

NOTE: All zone dampers and ductwork must be properly sup- ported according to local codes or SMACNA standards.

NOTE: Insulate damper using 1-1/2 in. insulation (check local codes). In areas where excessive condensing may occur, carefully
