CONFIGURING UNITS FOR DOWNFLOW (VERTICAL) DIS- CHARGE

Before performing service or maintenance operations on the system, turn off main power to unit and install lockout tag or electrical shock could result.

2. Remove return duct cover located on duct panel by breaking four (4) connecting tabs with screwdriver and a hammer. (Fig. 8 & 9)

3. To remove supply duct cover, break front and right side connecting tabs with a screwdriver and a hammer. Push louver down to break rear and left side tabs. (Fig. 8 & 9)

4. If unit ductwork is to be attached to vertical opening flanges on the unit composite base (jackstand applications only), do so

1.Open all electrical disconnects and install lockout tag before starting any service work.
