PRE‐ASSEMBLY OF MAIN DUCT | INSTALLATION OF MAIN DUCT KIT |
1.Determine if the duct is to be extended to the right of the unit or to the left. Install the end cap on the side opposing the extension. See figure below. If desired the end cap may be sealed with part of the foam tape provided with the kit. This is recommended to reduce possible leakage.
2.SET AIR DISTRIBUTION: The duct is factory preset for 80% main room and 20% adjacent room air distribution. Install the Volume Baffle provided for a 60/40 air distribution.
3.To install the Volume Baffle, position the baffle through the open end of the Main Duct (1) and align with holes in top of duct. Install two of the provided No.8 screws through the holes and into the baffle (2)
1.Place the Main Duct atop the Mounting Brackets as shown below (1). Install 4 No.8 screws to secure the duct to the Mounting Brackets (2). Do not fully tighten.
2.IMPORTANT! See figure below for duct position on brackets. Shift right or left based on your installation and final tighten the screws on bottom.
3. Re‐install the PTAC chassis and front cover.
NOTE: Access to the control panel and view of the controls will be restricted once the main duct is installed. The cover will not open fully or stay open by itself. It is suggested that a remote wired or wireless thermostat be used for convenience.
