6. Pipe sizes for the system must be selected on the
basis of the head [pressure] available from the
circulating pump.
7. Internal coil plumbing. Under each fan there is
a raised, insulated cover panel to be used when
internal pipe connections are desired. Either
remove this panel to run plumbing or punch
appropriately sized holes in the panel to allow
piping to pass without rubbing and space for
piping insulation, sealant and grommets (by
others).
Vent and drain connections are provided on
Greenheck water coils unless otherwise specified.
This allows the coils to be drained. Keep in mind
that when draining the coils, all water may not drain
from the coil. In order to completely drain the coil
to prevent the possibility of freezing during cold
ambient temperatures, air or nitrogen pressure must
be utilized to blow any remaining water from the
coil.
Coil Installation Checklist
Use the following checklist to verify that all necessary
installation procedures have been completed.
1. Coils are installed with airflow in same direction
as indicated on the coil nameplate or casing.
2. Condensate drain pans and piping is installed
with a trap in the condensate line and piping is
insulated and heated if installed in applications
that are below freezing.
3. Clean filters are installed upstream.

Change the filters regularly. Pressure drop readings
can be used to determine when a filter should be
replaced. Prefilters should be replaced at filter
manufacturers recommended pressure drop change
out or as required by system design.
All filter sections have access provided by a door.
Filters used in Greenheck ERS plenums can be
changed in most cases by sliding them out and
replacing. In some cases, filters are secured to frames
using a clip.
