ROOF MOUNTING
Install the unit a minimum of 6 inches (152 mm) above the roof surface to avoid ice build−up around the unit. Locate the unit above a load bearing wall or area of the roof that can adequately support the unit. Consult local codes for rooftop applications.
Removing and Installing Panels
IMPORTANT
Do not allow panels to hang on unit by top tab. Tab is for alignment and not designed to support weight of panel.
NOTICE
Roof Damage!
This system contains both refrigerant and oil. Some rubber roofing material may absorb oil and cause the rubber to swell when it comes into contact with oil. The rubber will then bubble and could cause leaks. Protect the roof surface to avoid exposure to refrigerant and oil during service and installation. Failure to follow this notice could result in damage to roof surface.
WARNING
To prevent personal injury, or damage to panels, unit or structure, be sure to observe the following:
While installing or servicing this unit, carefully stow all removed panels out of the way, so that the panels will not cause injury to personnel, nor cause damage to objects or structures nearby, nor will the panels be subjected to damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any weather conditions, especially windy conditions, that may cause panels to be blown around and battered.
LOUVERED PANEL REMOVAL
Remove the louvered panels as follows:
1.Remove two screws, allowing the panel to swing open slightly.
2.Hold the panel firmly throughout this procedure. Rotate bottom corner of panel away from hinged corner post until lower three tabs clear the slots as illustrated in detail B.
3.Move panel down until lip of upper tab clears the top slot in corner post as illustrated in detail A.
LOUVERED PANEL INSTALLATION
Position the panel almost parallel with the unit as illustrated in detail D with the screw side as close to the unit as possible. Then, in a continuous motion:
1.Slightly rotate and guide the lip of top tab inward as illustrated in detail A and C; then upward into the top slot of the hinge corner post.
2.Rotate panel to vertical to fully engage all tabs.
3.Holding the panel’s hinged side firmly in place, close the right−hand side of the panel, aligning the screw holes.
4.When panel is correctly positioned and aligned, insert the screws and tighten.
