Upflow application

In an upflow installation the discharge outlet is at the top. Care should be taken to insure unit is level to permit proper
condensate drainage. Normal upflow installation will be in a closet or basement. If installed in a closet, it must have a platform
framed in. The platform must have an opening centered in the closet that measures at least 12 inches in height from the floor. A
filter frame and filter can be used that covers the opening and is sealed to prevent air by-passing the filter. A filter grille can be
used that is located as described in RETURN AIR REQUIREMENTS section. The minimum filter size is shown in the table below.
Standard throw away air filter @ 300 ft/min or less
800 CFM = 20 x 20 x 1
1000 CFM = 20 x 25 x 1
1200 CFM = 20 x 30 x 1
1400 CFM = 25 x 30 x 1
1600 CFM = 25 x 30 x 1
1800 CFM = 30 x 30 x 1
2000 CFM = 30 x 40 x 1 or two 30 x 20 x 1

Another option is to use the Filter Base Accessory Kit. This filter base is placed on the closet floor and secured with screws. The
unit is placed on top of the filter base and secured to the base with screws. Use seal strip, tape or calking to seal between the
unit and the base.
Connect the supply air outlet to a plenum to the top of the unit and secure it with screws. Use a Non-tape sealant such as mastic
or an aerosol sealant to seal duct leakage. If installed in a basement, run supply and return duct work in accordance with local
codes. Use a Non-tape sealant such as mastic or an aerosol sealant to seal duct leakage.
