Changing Circuit Breaker Orientation
For Air Handlers with Circuit Breaker Line Voltage
Connections:
If the MX Series Air Handler is positioned in a horizontal
left-hand discharge this position will require no change in
the circuit breaker installation orientation. However, if the
Air Handler is installed in a horizontal right-hand discharge
position, the breaker will need to be installed so that the UP
position of the breaker is the ON position. The circuit
breaker orientation change is required by UL 1995, Article
26.18 (25 Sep 2005).
NOTICE
Copper tubing is recommended, but other
approved materials are acceptable.
WARNING!
Solder joints on domestic water lines are to
be made with NO-LEAD SOLDER.
NOTICE
The State of MA requires the use of a
pump timer on domestic water applications
to periodically circulate water during the off
cycle. This pump timer requirement is a
standard factory installed feature on all MX
Series Air Handlers with hot water coils. A
50’ maximum distance between water
heater and air handler is also required.
NOTICE
In addition to the standard factory installed
freeze protection control on all MX Series
Air Handlers with hot water heat it is
recommended that all water piping be
adequately insulated to prevent freezing
when piping is run in an unconditioned
space, such as attics, crawl spaces, or
within structures that may be unoccupied
during freezing conditions.
