Mechanical Installation, continued
For in-plenum/AHU installation:
Mounting varies with bracket-style. Follow mounting instructions
provided with bracket. Typically, provide 101.60mm inches of clearance from walls. Units should
be installed to allow easy access for maintenance. Install units so that the 5-step power adjustment
knob and status light are easily accessible.
The backer-plate is intended for non-sheet metal duct installations where extra support of the unit is
required. It may also be used for sheet-metal ducting. The backer-plate is meant to be installed on
the inside of the duct, sandwiching the duct between the plate and the Matterhorn unit.
1. Mark the drill holes for the studs to mount the Matterhorn to the backer-plate. The backer plate
captive nuts face forward.
2. Using an appropriate drill bit, 4.76mm, to drill the holes for mounting the backer-plate, then at-
tach the backer-plate, inserting the studs into the holes, and using the tab, bend over tabs out-
ward and flat to duct wall to retain backer plate to secure the plate to the duct.
Attach the Matterhorn series system using the six 6.35mm screws. The studs on the backer-plate
will secure the Matterhorn series
Electrical Installation
AtmosAir Matterhorn series systems require approximately 6-20 watts depending on number and
size of tubes.
Follow proper electrical procedures, guidelines, and codes for providing power to the systems,
including requirements for conduit, sufficient ampacity, phase balancing, etc. Electrical
installation should be performed by a qualified electrician.
Field electrical connection, 3-wire to junction box or country specific cord-set.
Each Matterhorn series unit is typically shipped with a 3m power cord with a C13 Computer Type
connector on one end and a Chinese CHI-10P Style 3 Prong plug on the other end. The plug can
be cut off and wires stripped for junction box installations
!!!WARNING!!!
The secondary voltage to the ionization tube can be as high as 3000 volts AC. Do NOT connect to
power before the installation is complete and all personnel are aware of imminent operation. Always
disconnect power to the unit before handling any of the components.
!!!WARNING!!!
