DUCT CONNECTIONS
Use 1/2" screws to connect ductwork to bottom of unit. Longer screws will pierce the drain pan and cause leakage. If pilot holes are drilled, drill only though field duct and unit bottom flange.
NOTE: The electric heat accessory should be installed before the sup­ply air duct is attached to the supply air openings. Refer to the electric heater kit instructions for proper installation.
Air supply and return may be handled in one of several ways best suited to the installation. See Figure 4 for dimensions for duct inlet and outlet connections.
The vast majority of problems encountered with combination heating and cooling systems can be linked to improperly designed or installed duct systems. It is therefore highly important to the success of an instal­lation that the duct system be properly designed and installed.
Use flexible duct collars to minimize the transmission of vibration/noise into the conditioned space. If electric heat is used, non-flammable material must be used.
Where return air duct is short, or where sound may be a problem, sound absorbing glass fiber should be used inside the duct. Insulation of duct work is a must where it runs through an unheated space during the heating season or through an uncooled space during the cooling season. The use of a vapor barrier is recommended to prevent absorp­tion of moisture from the surrounding air into the insulation.
The supply air duct should be properly sized by use of a transition to match unit opening. All ducts should be suspended using flexible hang­ers and never fastened directly to the structure. This unit is not designed for non-ducted (freeblow) applications. Size outlet plenum or transition to discharge opening sizes shown in Figure 4.
Duct work should be fabricated and installed in accordance with local and/or national codes. This includes the standards of the National Fire Protection Association for Installation of Air-Conditioning and Ventilat­ing Systems, NFPA No. 90B.
A suspension kit is available. Models 1BH0601 (unit sizes 018-060) is designed specifically for the units contained in this instruction (upflow application only). For installation of these accessory kits, see the instructions packed with the kit.
For suspension of these units in horizontal applications, it is recom­mended to use angle steel support brackets with threaded rods, sup­porting the units from the bottom, at the locations shown in Figure 5.
COIL METERING DEVICES
The coil in this Air Handler unit will have a TXV metering device installed at the factory.
The model number will have the following format: F*FPxxxH06T2y - The coil will have a Thermal Expansion Valve (TXV) installed. The y character specifies which TXV is installed at the factory. Please refer to the TXV Metering Device section for installation notes.
