Coil Change Out Procedure
Coils can only be pulled out through the side of the
plenum cabinet. Side panels which are nearest to the
coil can be removed if the coil needs to be replaced.
Size 020 ERS plenums only have a single coil and do
not require coil removal clearances on both sides. If
necessary, both coils can be removed through the
same side of the plenum housing. This process would
require the removal of an additional spacer panel that
separates the two coils within the unit.
