Filter Replacement

Filters are located only in the coil plenum section. Access is needed from both sides of the plenum to change all the filters. Unit may have either 2 inch MERV 8 filters or 4 inch MERV 11 filters depending on the application requirements. Use equivalent MERV rating filters when replacing.

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.

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).

NOTE

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.
