The electronic expansion valve (EEV) in this unit is shipped in the closed position to protect the valve during transportation. Prior to brazing, line
power must be applied to the air handler field wiring terminals for 1 minute. The initial power causes the EEV to open allowing nitrogen to flow
through the system during the brazing process.
If power cannot be applied to the EEV control board prior to brazing refrigeration piping, a tool is available to manually operate the EEV. An EEV
manual operating tool can be purchased from Source 1 as part number S1-02649686000. Six revolutions of the tool open the valve fully.
SECTION I: GENERAL
The single piece air handler series provides the flexibility for installation
in any position. This unit may be used for upflow, downflow, horizontal
right, or horizontal left applications.
These units may be located in a closet, utility room, attic, crawl space,
or basement. These versatile models may be used for cooling or heat
pump operation with or without electric heat.
Top or side power and control wiring, color coded leads for control
wiring, easy to install drain connections, and electric heaters all
combine to make the installation easy and minimize installation cost.
Electric heat kits are available as field installed accessories. Single
phase kits are available from 2.5 kW to 25 kW. 208-230 volt three
phase kits are available from 10kW to 25kW.
