approximately 3 amps @ 24 V. For long runs where the conductor size becomes too large,
an interlocking relay (field provided) should be used.
A dry contact (24 volts rating) is provided for terminals for a remote alarm connection.
If the control panel includes a condensate probe, make sure it is mounted below the unit
against the floor area where water may collect. To check the operation of the probe,
submerse it in a cup of water. The condensate alarm should energize.

STARTUP AND TEST PROCEDURE

A. With all power to unit off – Check that all wiring is correct
Check that properly sized fuses are installed in the disconnect switch. Correct fuse
size and minimum circuit ampacity are listed on the unit nameplate. Now, check the
wiring connections in the Main Control Panel to see if they are tight. It is best that
this be checked prior to operating the machine. After checking, close the Main
Control Panel cover and proceed as follows:
Solid-State Control Panel - With the system switch in the "OFF" position, apply
power to the unit. The "Power On" light should illuminate.
B. Check for correct phasing
The equipment should now be checked for correct phasing required to make the
blower motor turn in the correct directions. For this test it is necessary to open the
front access panel or the right side doors of the unit to observe the blower and
blower motor. Now, momentarily switch the system switch to the "ON" position and
then back to "OFF". The blower will have started and it is therefore possible to
determine rotation. On Compu-Aire units, the blower should be rotating in a
CLOCKWISE direction in the down flow units and COUNTER CLOCKWISE in the up
flow units, looking in the right side of the unit. Heaters and humidifiers are not
affected by phasing.
