1.1 Description of Operation
This air handler is a direct-fired, electric, steam, hot
water and/or energy recovery heated fresh air
appliance. It is designed for indoor or outdoor
installation with fresh outdoor air delivered to the
burner. Air handlers are designed to operate in
temperatures as low as -30 °F (-34 °C) variable
frequency drive is only approved for applications
15 °F (-9 °C) and above, unless a control enclosure
heater is installed. The air handler is factory-tested
and may be designed to operate using natural gas or
LPG (check the air handler's rating plate for
information on the appropriate gas). The heat will
modulate to maintain the selected supply air
temperature or room air temperature, depending on
the selected controls. See Page 92, Section .
The air handler may be provided with several
different controls and options to meet various
application requirements. Be sure to read this entire
manual before installation and start-up.
1.2 Inspection and Setup
The air handler may ship in multiple sections based
upon the configuration selected. The air handler was
inspected and operated prior to shipment.
Immediately u
pon receipt of the air handler, check
the fuel and electrical requirements of the air handler
and verify that they match the fuel and electrical
supply available. Verify that the specifications on the
air handler rating plate match the order. Check the air
handler for any damage that may have occurred
during shipment. If any damage is found, file a claim
with the transporting agency. Do not refuse
shipment. Check the installation location to ensure
proper clearances to combustibles. See Page 8,
Section 3.1.
Any small options which do not come attached to the
air handler will be found inside the air handler.
Larger accessories (i.e. legs, stand, filter section,
inlet hood) may either ship with the air handler or
separately on another truck. Check the bill of lading
for information.
