Air Handler and Evaporator Coil. GENERAL These evaporator units may be suspended from joists with isolation type hangers or hooks. Suspension accessories 1HH0403 (25 and 30 Ton), 1HH0404 (40 Ton) and 1HH0405 (50 Ton Air Handler with Evaporator Coil) may be ordered separately. All Suspension accessories include three suspension channels and hardware. The channels extend across the evaporator coil section, the heating coil section (if included) and the blower section. Each channel is to be bolted to each section as shown in Figures 1 thru 4. 25/30/40 TON MOUNTING These evaporator units may be suspended from joists with isolation type hangers or hooks. Suspension accessories 1HH0403 (25 and 30 Ton) and 1HH0404 (40 Ton) include three suspension channels and hardware. The channels extend across the evaporator coil section, the heating coil section (if included) and the blower section. Each channel is to be bolted to each section as shown in Figures 1 and 2.

When used to support a vertical unit, these channels should be cut to match the bottom dimension of the evaporator section. 2 The suspension channels have two sets of mounting holes to accommodate horizontal units with or without a heating coil. On a horizontal unit without a heating coil, the suspension channels will extend 3 beyond both ends of the unit. 3 The same channels can be used to support a horizontal, floormounted unit from below. 4 After these bottom channels are cut per Note 1, a new hole will have to be drilled at the cut end if the unit is to be mounted on isolators.

4 50 TON MOUNTING These evaporator units may be suspended from joists with isolation type hangers or hooks. Suspension accessory 1HH0405 (50 Ton Air Handler with Evaporator Coil) includes three suspension channels and hardware. The channels extend across the evaporator coil section, the heating coil section (if included) and the blower section. Each channel is to be bolted to each section as shown in Figures 3 and 4. The suspension channels require no drilling or cutting. Each channel has enough holes in its bottom flange for: 1. Four bolted connections to the evaporator coil section. (Only two are used on the outside supports) 2. One bolted connection to the heating coil section. 3. Four bolted connections to the blower section. (Only two are used on the outside supports) See Figure 4 details for securing suspension channels. When the heating section is not included, each channel will extend 3" beyond the front and the rear of the unit. Bolt holes in the bottom flange of each channel will still align with the holes provided in the top framework of the evaporator section and the blower section. For both outside channels and for the Point 1 locations on the center channel, the bolted connections are to be made where the top sheet metal panels are attached to the unit framework. The ¼ screws and cage nuts must be removed and may be discarded. For the Point 2 locations on the center channel, the bolted connections are to be made through the knockouts in the top sheet metal panels. 5/16 cage nuts are provided in the unit framework under these knockout locations. Note that these cage nuts are part of the basic unit. They are not supplied with the suspension accessory.
