Site Preparation
1. Provide clearance around installation site to safely rig and lift equipment into its final position.
Supports must adequately support equipment. Refer to manufacturer’s estimated weights.
2. Compressor Unit must be within 75 Ft of air handler unit.
3. Compressor Unit must not be near intake of air handler unit.
4. Consider general service and installation space when locating unit.
Assembly
There are several items shipped loose with the DX coil modules. These items include sheet metal
screws, nuts and bolts, and foam gaskets. It is important to know where the coil is to be installed. For
direct fired heaters and electric coil modules, the DX coil module mounts to the end discharge side of the
air handling unit. This keeps any refrigerant leaking from burning, avoiding the creation of toxic gasses.
Place caulk on the outside of any external screws used to prevent water leaks.
Upon unit arrival, follow the following procedure to assemble the DX coil.
For use with a direct fired or electric heater:
1. Attach the DX coil module to the discharge side of the air handler using the nuts, bolts and angle
bracket washers included. Apply the foam gasket to the air handler to ensure that there is a liquid
tight seal formed between the DX coil module and the air handling unit.
2. Attach the down discharge plenum to the end of the DX coil module using the supplied foam
gasket, nuts and bolts. Or, attach ductwork directly to the end of the unit using sheet metal
screws following SMACNA guidelines.
For use without a direct fired
or electric heater:
1. Attach the DX coil
module to the intake
side of the air handler
using the nuts, bolts and
angle washers included.
Apply the foam gasket to
the air handler to ensure
that there is a liquid tight
seal formed between the
DX coil module and the
air handling unit.
2. Complete installation of
ductwork per SMACNA
standard installation.
