General Installation Instructions of the Classroom Air Handler
Refer to custom shop and installation drawings and instructions in the Information Package that was sent with the Unit
for exact measurements, descriptions and installation details
1.
Once the Rear Standoff (RSO) or Rear Plenum Assembly (RPA) installation has been completed (if applicable) and the Wall
Sleeve has been installed, proceed with fastening the Classroom Air Handler in place. (Refer to Pg. 25, 26)
2.
To assure a tight seal between the unit (or standoff) and the wall, apply foam tape to the 1” wide mounting edge and to any
partitions of the rear standoff (or unit).
Tip: Keep the tape back from the outside edges by at least ¼” so the tape does not become unsightly when compressed.
3.
If the unit has a cooling coil and drain pan, pass the drain hoses that come out the back of the unit through the wall sleeve.
These hoses must gravitate drain downward to the outside as they pass through to the exterior louver. They must allow
condensate to drain freely to the outside without restriction and without inhibiting the operation of the dampers. (It will be
necessary to cut away enough of the bird screen in the back of the exterior louver to allow the condensate hoses to pass
between the blades of the louver to the exterior.)
4.
Check to be sure that the back of the Classroom Air Handler is centered directly in front of the wall sleeve opening, and then
carefully slide the air handler back into place (the unit must be level).
5.0 Installation Guide
Classroom Air Handlers weigh anywhere from 420lbs to 1070lbs and may be heavy. Care
must be taken in the handling and moving of this unit to prevent it from becoming unstable and
tipping over once the shipping crate is removed. Never lean a ladder against the unit or put
weight on or against the unit prior to completing the installation as it may tip.
5.1 General Assembly and Installation
It is important to read and understand the instructions outlined in this document, as well as any job specific documentation
provided in the Information Package before proceeding with the installation.
Care should be taken to protect the painted finish when handling the unit and accessories.
You may require an assistant's help for this procedure.
The condensate hose is supplied with a loop (trap). DO NOT REMOVE THIS LOOP. If the loop
is removed the drain pan may overflow causing water damage inside and outside the ventilator.
