User Manual

Stopping and WindGuard units are shipped with
coil(s) factory mounted.
Once the coil has been secured to the cabinet,
access to the motor and fan is through the
removable access panels located on the top of the
cabinet.
Note: Low Profile and Wind Stopping units require
the removal of the coil to access the motor and/or
fans.
All piping should be done by a licensed pipe fitter
and in accordance with local codes and
regulations. Connect the supply and return fittings
as required. All traps and valves are sized and field
installed by others. Standard coil configuration is
right hand supply and left hand return. (FIGS. 3 &
4) Optional temperature controls, if ordered, are to
be field installed by others.
