Section 5) INSTALLATION OF UNIT (Continued)
5. Ensure the unit is level, otherwise condensate water cannot drain properly.
6. Using a level and/or measuring tape, ad-
just the height of the bottom of the unit
to be level or slightly higher (not more
than 1/16”) than the lower part of the
finished ceiling. Tighten the nuts and
counter nuts of the threaded rods to se-
cure in place.
7. Connect all supply and return water connections to the unit. It is recommended to use a vibration
eliminator, such as a flexible connector, to prevent the transmitting of vibrational noise. Use a back-up
wrench on each of the chilled water and hot water connections to prevent damage to the coil assem-
bly. Connect the condensate drain to a gravity drain in compliance with all codes. After connection of
the chilled water and hot water lines, as well as the condensate drain, verify that the unit remains
level.
8. Make electrical supply connections in accordance with all code requirements.
9. Install all field supplied controls.
10. Fresh air connections should be made at this time. There are two connection locations for fresh air on
the unit cabinet. See the drawings on page 8 for location of cabinet openings. Contractor should sup-
ply and field fabricate boots for these connections to meet job requirements as needed.
11. Reinstall cover assembly with the four (4) shoulder screws removed earlier. DO NOT OVER TIGHTEN.
12. Unit is now ready for contractor start-up procedures and recording of benchmark data according to all
local and national requirements.
This source of fresh air MUST BE DELIVERED TO THE UNIT UNDER POSSITIVE PRES-
SURE as these units are not rated for static pressure.
This source of fresh air must be turned off when the unit is not in operation to
prevent the introduction of unconditioned air into the conditioned space.
This source of fresh air must be filtered.
