INSTALLATION
AtmosAir 880 series equipment can be mounted in an air handler
wall, using the faceplate mounting flange and its weather-strip
gasket; or inside a plenum using a semi-custom mounting
bracket. The units operate best when located after all filters,
coils, and fans. Various mounting arrangements are possible;
however, the available options may be limited due to size and
configuration restrictions. Use the
Duct Cut-Out Procedure
for
ideal placement of the Matterhorn 880/882 models.
When mounted on the side of a duct or air handler wall, the
enclosure should not be exposed to moisture. If installing
outside, a weatherproof enclosure with an access panel for
servicing should be installed over the AtmosAir equipment.
Contact AtmosAir Sales for A.W.E. specifications.
The AtmosAir Matterhorn 880 series operates on 220-250
VAC, 50/60 Hz. The tube and electrode contacts should not
come into contact with any conductive surface. A minimum
101.6mm (4”) clearance around the tube is recommended.
Mechanical Installation
1.
Carefully remove the equipment from its shipping
container. Inspect the main components, gasket, and
tube(s) for damage. Verify that the unit’s voltage rating is
the same as the available voltage, 220-250 VAC.
2. Install the ionization tube:
Gently pull the conductor
strap back to allow the tube to turn freely; screw the end
screw of the tube into the tube holder hand-tight utilizing
the blue cap,
DO NOT TWIST THE TUBE OR MOVE THE
EMITTER SCREEN. DO NOT OVER-TIGHTEN THE TUBE!
Once the tube is secure, return the conductor strap to its
normal position and
ENSURE SOLID, FLAT CONTACT IS
MADE WITH THE TUBE’S OUTER MESH.
3. Location and Orientation:
Install the unit downstream
of filters, coils, and fans with the ionization tubes vertical
whenever possible (When installing a dual F Tube setup,
the tubes MUST be mounted vertically, and ‘S’ clips are
recommended); If multiple units are installed in the same
duct, stagger the units in the airflow so they are not in the
same airflow path.
4.
The standard Matterhorn 880/882 power cord is 3.05
meter (10’) long. Be sure to consider receptacle location in
your placement plan. The receptacle or junction box must
be within 2.45 meters (8’) of the M880/882.
5. For in-duct installation:
Verify the flange gasket is in
place and not damaged to ensure the unit seals properly.
When making a cut-out in the duct, ensure there is at least
25.4 mm (1”) clearance from the duct wall on all four sides
before cutting the 139.7mm (5½”) high × 152.4 (6”) wide
mounting cut-out. A galvanized steel template is included
for ease of installation; use the inner lines to cut the cut-
out hole, then trace the cut-out and mark the locations
of the mounting holes for the Matterhorn 880 series. The
semi-circular cutout in the template should be oriented
upstream if possible.
6.
Using the marked holes from the backer-plate template,
affix the unit securely in the duct using self-tapping
screws (if not using backer-plate). Do not over-tighten,
this may strip the screw hole. The unit is self-sealing to the
duct, so no further sealing is needed.
