START-UP INSTRUCTIONS
Before beginning a start-up on this equipment make sure you followed all the instructions in the above sections
correctly.
WARNING!
This unit is connected to high voltages and contains moving parts that can start unexpectedly. Electrical shock,
severe injury or death could occur if instructions given in this manual are not followed. Always disconnect
and lock out power before servicing this equipment. All work should be done by a qualified technician. DO
NOT bypass any interlock or safety switches under any circumstances.
Proper commissioning of this equipment is the responsibility of the installing contractor. It is recommended
that an air balance be completed before the unit start up by a certified air balancing contractor to ensure that
the air volume being sent downstream of the unit into the ventilation system matches the unit rating label.
Failure to perform a proper air balance can cause injury or death, damage to the equipment, property
damage, system operational problems, or be a cause of poor indoor air quality. Moisture carry over can also
result from improper air flow.

Fan adjustment
1.
Check voltage of each phase at main electrical disconnect.
2.
Check fan rotation and modify electrical connection if required.
3.
Ensure that the VFD (if equipped) is set according to the full load amperage (FLA) as indicated on motor
name plate.
4.
Check alignment and belts tension.
5.
Check for vibration or unusual noise.
6.
When dampers are completely opened, with fan running, read amperage at each motor phase and check
if it corresponds to the project design BHP, as shown on the unit rating label.
CAUTION!
Excessive vibration may be experienced during the initial start-up. Left unchecked, it can cause a multitude
of problems including structural and/or component failure.
