INSTALLATION

Step 1 — Place Units in Position
A factory tag is on top of each unit. The tag states riser tier
number, floor, room number (if furnished), and supply-air ar-

that marked on the unit identification tag. If no specific detail
is shown on tag for unit location, then determine configura-
tion for the Universal unit based on information within this
manual. Should any questions arise regarding unit configura-
tion, contact the sales representative or the factory BEFORE
proceeding. Remove unit from pallet and take directly to as-
signed space for installation. While all equipment is designed
and fabricated with sturdy materials and may present a rug-
ged appearance, great care must be taken to assure that no
force or pressure be applied to the coil, risers or piping during
