DIRECT DRIVE
INSTRUCTIONS FOR
CHANGING BLOWER
SPEED
DISCONNECT THE ELECTRICAL
SUPPLY TO THE AIR HANDLER
BEFORE ATTEMPTING TO
CHANGE THE BLOWER SPEED.
FAILURE TO DO SO CAN CAUSE
ELECTRICAL SHOCK RESULTING
IN PERSONAL INJURY OR DEATH.
The blower motor must be wired for
blower speeds required for normal
operation.
If additional blower speed taps are
available (leads connected to “M1” and
“M2” on the electronic control), speeds
may be changed if necessary to fit
requirements of the particular
installation. Reconnect the unused
motor leads to “M1” or “M2.” Check
motor lead color for speed designation.
!
WARNING
HYDRONIC AIR HANDLER AIR FLOW PERFORMANCE - RHWBTABLE 6
Note: When selecting a motor speed tap, use the lowest speed tap possible to achieve the rated cooling air-flow at the external static
pressure for the application (including cooling coil).
Heating speeds should not be
reduced where it could cause the air
handler air temperature rise to
exceed the maximum outlet air
temperature specified for the unit.
IMPORTANT: Always check air
temperature rise after changing the
heating speed for any reason.
