IMPORTANT SAFETY INSTRUCTIONS

INSTALLATION INSTRUCTIONS FOR ZONEMASTER™ MOTORIZED ADJUSTABLE DAMPER

READ AND SAVE THESE INSTRUCTIONS

WARNING

To reduce the risk of fire, electric shock or injury to persons, observe all instructions. The ZoneMaster™ has been designed to operate on 24 Volt AC, 60 Hz.

Maintain a minimum clearance of 4” (10 cm) from any combustible material or surface to the Transformer and/or the ZoneMaster™ electric motor.

This damper is designed to control the flow of heated or cooled air in air distribution systems only. Never close more than 20% of the total air distribution system at a time. The

restricted airflow through a furnace or air handler may cause damage to the air delivery and /or air conditioning equipment. This damper must never be used to control the flow

of combustion air, flue gas or other toxic or hazardous gases or applications where failure of the damper can cause damage to persons, property or equipment and/or create a

risk of fire, suffocation or death.

IMPORTANT NOTES

The following will be required to complete the installation:

• A standard low voltage Heat-Cool wall thermostat, designed for gas furnaces.

• Electrical wire, 2-conductor, 20 Gauge (CL-2 or Bell Wire) to connect the Transformer to the Damper via the wall thermostat. If the total length of wire exceeds 80 feet (25 m),

use 18 gauge wire. If two or more Dampers are wired in parallel (maximum 2 Dampers per each included 20 VA Transformer), use 18 gauge wire.

• If you are mounting the Damper between floor joists in flexible duct, you will need two duct supports.

• Aluminum foil duct tape.

BENEFITS

The ZoneMaster™ will allow you to individually control the temperature of a room in your home. e.g. An unused room does not have to be heated or cooled to the same

temperature as the remainder of the home. In the winter you may want a bedroom a little cooler than the rest of the home. The baby’s room you may want a little warmer than

the rest of the home in the summertime. You control your comfort and save significantly on energy use.

SELECTION

Choose a normally closed Damper (ZCxxx) if you want the airflow restricted when the Damper is un-powered. This is typical for the thermostatic control.

Choose a normally open Damper (ZOxxx) if you want the airflow restricted when the Damper is powered.

INSTALLATION INSTRUCTIONS

Consult the Wiring Diagram when planning the installation. Begin by determining the location of the Damper, the thermostat and the Low Voltage Transformer. Then determine

the route you will be running the wires from the Transformer to the thermostat and onwards to the Damper. Once you have this planned, proceed as follows.

DAMPER UNIT INSTALLATION

For metal duct, remove a 6” (15 cm) section of duct at an existing joint so you will have one crimped duct end and one straight duct end. Slide the Damper unit in place so that

the ends are inserted at least 1” (2.5 cm) at each end. The crimped duct work end should be inserted no more than 2" (5 cm) inside the female end of the Damper or it may

interfere with the Damper plate. The Damper is non-directional so it may be installed facing either direction of the airflow. Rotate the Damper so that you can easily access the

electric terminal block. Complete the installation by securing the Damper with the #6 sheet metal screws supplied. Finish the installation by covering the seams in the duct with

a good quality aluminum foil duct tape.

For flexible duct, cut the flexible duct and slide the ends over the ends of the Damper unit. You will need to support the Damper with a couple of standard duct supports

available at Home Centers. Complete the installation by securing the Damper to the flexible duct with a good quality aluminum foil duct tape or nylon cable ties. Take care to

ensure that the outer jacket and insulation do not interfere with the Damper mechanism. Make sure that the chosen method to secure the Damper to the duct does not deform

the body of the Damper pipe. If the Damper pipe is severely “out of round”, the spring return mechanism may not function properly.

THERMOSTAT INSTALLATION: (THERMOSTAT NOT INCLUDED)

The thermostat should be located within the space served by the vent(s) whose airflow is controlled by the new Damper(s). Mark the location of the thermostat mounting hole

in the back plate of the thermostat and install the fastening hardware normally supplied with the thermostat. Do not mount the thermostat on an outside wall. Locate the

thermostat approximately 5’ (1.5 m) above the floor and away from drafts and direct sunlight. DO NOT screw the thermostat to the wall at this time.

For general ventilation control use only.

Do not use to control the flow of hazardous, corrosive, flammable or explosive materials and vapors.

Never expose this product to temperatures exceeding 140°F (60°C).

Always leave this product accessible for maintenance, cleaning and repair.

Before installing or servicing this product, unplug the Transformer.

HOW TO ADJUST DAMPER PLATE POSITION The amount of airflow through the Zone Master Motorized Adjustable Damper in either the powered or unpowered position can be adjusted by changing the final or initial position (angle) of the damper plate. The position of the damper plate is controlled by the coupler mechanism. When the unit is powered, the motor will rotate the coupler mechanism counter-clockwise until the final “powered” plate position is reached.

To adjust a normally closed ZC*** damper’s unpowered spring-return position: 1. Detach the spring from the motor bracket. Make note of the excess spring length below the bracket. This is important in setting the proper spring return force. 2. Loosen the set screw in the Outer Ring until the Outer Ring can freely rotate independent of the Inner Ring. 3. Rotate the plate to the intended closed position using the Inner Arm. 4.

Le mécanisme du coupleur comprend 3 parties: (1) Vis de réglage Emplacement adéquat du ressort sur le coupleur. (2) Anneau et bras intérieur L’anneau et le bras intérieurs (2) sont reliés à l’arbre du registre. L’anneau et le bras extérieurs (3) peuvent tourner pour modifier la position de l’angle de la plaque au début et à la fin de la mise sous tension. La vis de réglage (1) bloque l’anneau extérieur en place.

Pour ajuster la position du ressort de retour d’un registre de contrôle d’air ZC*** normalement fermé (hors tension) : 1. Détacher le ressort du support de moteur. Noter la longueur excédentaire du ressort sous le support. Ceci est important pour déterminer adéquatement la force de rappel du ressort. 2. Desserrer la vis de réglage dans l’anneau extérieur jusqu’à ce qu’il puisse tourner librement et indépendamment de l’anneau intérieur. 3.
