Unit Start-Up

Supply Fan (Plenum Type)

The APEX-200 contains one plenum supply fan located on the end of the unit opposite the outdoor air intake (see beginning of Unit Start-Up section for diagram of unit layout). Efficient fan performance can be maintained by having the correct radial gap and overlap. These items should be checked before start-up and after the fan has been in operation for 24 hours.

Radial Gap: Radial gap is adjusted by loosening the inlet cone/ring on the wheel. If additional adjustment is required to maintain a constant radial gap, loosening the bearing bolts and centering the wheel is acceptable as a secondary option.

Overlap: Proper overlap is obtained by loosening the wheel hub from the shaft and adjusting the wheel to maintain an ‘A’ dimension of 11 7⁄16 ± 3⁄8 inches (see FIGURE 16).

Spring Vibration Isolators on Supply Fan

Three to four Z-brackets prevent unwanted fan and isolator movement during shipping. Proper unit operation requires the removal of these brackets.

1.Remove the 5/16 in. hex head bolts from each Z-bracket and fan base.

2.Pull Z-bracket out from the fan base.

3.Replace the bolts to their original position in the fan base.

Exhaust Fans (Forward Curved Type)

The APEX-200 contains two forward curved exhaust fans located on either side of the unit (see Basic Unit Operation). These forward curved fans should be checked for free rotation. If any binding occurs, check for concealed damage and foreign objects in the fan housing. Be sure to check the belt drives per the start-up recommendations in the following section.

Fan Performance Modifications

Due to job specification revisions, it may be necessary to adjust or change the sheave or pulley to obtain the desired airflow at the time of installation. Start-up technician must check blower amperage to ensure that the amperage listed on the motor nameplate is not exceeded. Amperage to be tested with access doors closed and ductwork installed.

SAFETY CAUTION!

When operating conditions of the fan are to be changed (speed, pressure, temperature, etc.), consult Greenheck to determine if the unit can operate safely at the new conditions.
