Access Door Reassignment For Integral En-
closure
ELECTRICAL SHOCK HAZARDS
All power must be disconnected pri-
or to installation and servicing this
equipment. More than one source
of power may be present. Discon-
nect, lock out and tag out all power
sources to avoid electrocution or
shock hazards.
1. Locate line voltage and control voltage doors,
remove door hinges from the unit, and set doors
aside.
2. Remove electrical enclosure side access panels.
3. Remove electrical enclosure top access panel.
4. Reinstall electrical enclosure top access panel to
top of unit.
5. If unit has disconnect switch or line block op-
tion: Remove the line voltage enclosure central
bracket, flip 180 degrees, and reinstall.
6. If unit has toggle switch option: Remove the
toggle switch and toggle switch bracket. Relocate
toggle switch and toggle switch bracket to the
bottom side of the electrical enclosure.
7. Reinstall electrical enclosure side access panels.
8. Reinstall control enclosure door, line voltage door,
and hinges to the bottom of the unit.

OPERATION

Start-Up

Thorough safety precautions should always be taken
when performing startup and service. Refer to safety
considerations at the beginning of this Operation Manual
and the Inspection & Start-Up Checklist in this section.
Only qualified individuals should perform these tasks.
Prior to start-up, the project control sequence/wiring
diagram should be obtained and thoroughly understood.
If factory-supplied or consignment DDC controls are
utilized, refer to the applicable Operation Manual for
start-up and balancing information. Check that all
electrical work is finished and properly terminated.
Check that all electrical connections are tight and that
the proper voltage is connected.
JOHNSON CONTROLS

Power Requirements

Three Phase AC power imbalance must not exceed 2%.
Be sure that the following guides are met:
1. AC power is within 5% of rated voltage at rated
frequency. (See equipment nameplate for ratings)
2. AC power total harmonic distortion (THD) must be
limited to 5%.

Primary Air Damper And Fan Adjustment

Unit should not be balanced until the incoming power
supply is at the permanent voltage condition. All
discharge ductwork must be connected. The minimum
recommend discharge static pressure for all fan-
powered equipment is 0.1" wg. and 0.2" on 3/4hp and
larger (see fan curves located on the Johnson Controls
website for specifics). All foreign materials should be
removed from the duct system. Optional filters should
be installed as required.

EC Motors

For units with EC motors, all fan-powered equipment
is shipped with an Solo or Sync PWM Motor Control
Board. On standard units, the Solo or Sync Control
Board is mounted directly in the bottom electrical control
enclosure access door. On units with a 90-degree
enclosure, the Solor or Sync PWM is mounted on the
front of the enclosure door.
For specific balancing instructions related to the Solo
and Sync PWM Motor Control Boards, please refer to
the EC Motor Solo, Select and Sync PWM IOM located
at the Johnson Controls website IOM section: www.
johnsoncontrols.com. An example of the fan calibration
curve is located on page 40 of this IOM. A unit-specific
fan calibration curve will be affixed to the unit.
