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. Refer to Performance Climate
Changer™ Air Handler Sizes 3 to 30 for Indoor and Outdoor
Applications - Product Catalog (CLCH-PRC024*-EN).
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
Table 10, p.
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.
