CONNECTING AIR TUBES TO DAMPERS
Each zone has one air line bulkhead fitting on the top of the Arzel
®
panel. Each air line provides
vacuum and pressure, as needed, to open and close the dampers. All additional dampers in each zone
must be connected with a “T“ fitting to its main zone air line. For example: Zone #1 air line must be
connected to all the dampers in Zone #1. A cap or plug must be placed on any unused zone fittings or
tubes. Tubing is available in eight colors to easily identify each zone.
IDENTIFYING THE ZONES
Tubing is available in eight colors for easy tracing and identification of dampers. To avoid zone mix-ups,
mark all supply ducts clearly with room designation and proper zone number. The Arzel Duct-Finder™
makes duct tracing easy.
DAMPER POSITION INDICATOR
Observe the movements of the damper position indicator (Fig. 15a). Yellow indicator shows the position
of the damper. Note: Not to be used as a manual override.
