6.7- INSTALLATION OF THE INDOOR COOLING COIL
Check the coil for shipping damage and verify the contents of the box
containing the evaporator coil. If you should find damage, immediately
contact the last carrier. Coils are shipped with a 10 psi dry air holding
charge. Puncture rubber plug on suction line to release charge before
removing plugs. The absence of pressure does not verify a leak. Check
the coil for leaks before installing or returning it to your wholesaler.
Coil should be level, or pitched slightly toward the drain connection. Airflow
face velocity above 350 ft/min is not recommended for downflow or
counterflow applications due to potential water blow-off.
For an installation with a Chinook , position the coil on the supply outlet of
the furnace using sheet metal screws. Drain pans are made of a polymer
that can withstand temperatures up to 232.22°C (450°F). Maintain a
minim
um of 3” clearance over the heat exchanger.
For an installation with a Supreme , position the coil on the return outlet of
the furnace.
6.7.1- Multiposition coil
Multi-Position A-Coils come factory installed with a vertical and horizontal
drain pans and can be configured for upflow, downflow, horizontal blow-
through or horizontal pull-through installations. In the center opening of
vertical drain pan, a metal Inlet Air Restrictor is factory installed and is
required for horizontal applications. It may be removed for vertical
applications. Airflow face velocity above 350 ft/min is not recommended for
downflow or counterflow applications due to potential water blow-off.
For horizontal configurations, install splashguard (included) onto the coil
outlet, and extend
suction line insulation into the coil cabinet by 2” to
prevent moisture from dripping onto the insulation (the rubber grommet
may need to be moved). Splashguard installation is not required for vertical
configurations. Bottom flange of guard should rest on pan and sides
screwed to the duct flanges. See Figure 13 and Figure 14 for splashguard
instructions.
In downflow and counter flow configurations, aluminum foil tape must be
applied to seal the top edge of the insulation to the cabinet. This tape will
prevent the possibility of the insulation delaminating and blocking airflow.
In horizontal pull-
through and counter flow configurations, a minimum 12”
transition is required in front of the coil as shown in Figure 12. This is
required to ensure proper airflow distribution and to reduce pressure drop.
