General Information
Operating Environment
The Performance Climate Changer™ air handler is a
central station air handler for indoor and outdoor
applications. When considering the placement of the air
handler, it is important to consider the operating
environment. The acceptable ambient temperature range
for unit operation is -40ºF to 140ºF (-40ºC to 60ºC).
Do not operate unit above maximum fan speed or unit
airflow as shown in the unit fan curves. See these catalogs
for more information:

Handler Model UCCA for Outdoor Applications
Unit operation at greater than maximum fan speed can
drastically reduce bearing life and result in a catastrophic
failure. Operating at greater than the maximum allowable
airflow in the cooling mode may result in unsatisfactory
operation due to moisture carryover from the coil. In
addition, it is often not economical to operate a unit at its
maximum fan speed due to the greater motor power
requirements.
Do not operate units with electric heat below the minimum
airflow listed (see
).
This is to prevent
excessive leaving air temperatures and electric heat limit
trips.
Do not operate a hydronic (or steam) coil and electric heat
simultaneously. This is to prevent excessive leaving air
temperatures and limit trips. Electric heat units are
equipped with a lockout switch to disable the electric
heater if the temperature of the hydronic (or steam) coil is
greater than 95°F (35C).
For heating applications, a special motor may be required
to withstand the higher temperatures. Motors with Class B
insulation are acceptable for ambient temperatures up to
104º F, while motors with Class F insulation can withstand
ambient temperatures to +140º F (60º C).
Note:
Units with UL approval have a maximum ambient
temperature requirement of 104ºF. The customer
should provide adequate freeze protection for the
coils. See
for more
information.
