towards the end of the unit.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Remove all shipping materials and top skid. Remove extra
center post from the condenser end of the unit so that the
condenser end of the unit matches Fig. 19 -- 21. Recycle
or dispose of all shipping materials.
Step 7 — Convert to Horizontal and Connect
Ductwork (when required)
Unit is shipped in the vertical duct configuration. Unit
without
factory--installed economizer or return air smoke
detector option may be field--converted to horizontal ducted
configuration using accessory CRDUCTCV001A00. To
convert to horizontal configuration, remove screws from side
duct opening covers and remove covers.
Discard the supply duct cover. Install accessory
CRDUCTCV001A00 to cover the vertical supply duct
opening. Use the return duct cover removed from the end
panel to cover the vertical return duct opening.
Field--supplied flanges should be attached to horizontal
duct openings and all ductwork should be secured to the
flanges. Insulate and weatherproof all external ductwork,
joints, and roof or building openings with counter flashing
and mastic in accordance with applicable codes.
Do not cover or obscure visibility to the unit’s informative
data plate when insulating horizontal ductwork.
