Start-Up

Pre Start-Up Checklist 

 

check as items are 

completed.

o

  Disconnect and lock-out all power switches

o

  Remove any foreign objects that are located in the 

energy recovery unit.

o

  Check all fasteners, set-screws, and locking collars 

on the fans, motor bases and accessories for 
tightness.

o

  Rotate the fan wheels by hand to ensure no parts are 

rubbing. If rubbing occurs, refer to Start-Up section 
for more information.

o

  Confirm the EC motor voltage is correct. Reference 

unit wiring diagram.

o

  Filters can load up with dirt during building 

construction. Replace any dirty pleated filters and 
clean the aluminum mesh filters in the intake hood 
(refer to Routine Maintenance section).

o

  Verify that non-motorized dampers open and close 

properly.

o

  Check the tightness of all factory wiring connections.

o

  Verify control wire gauge (refer to the Electrical 

Connections section).

General Start-Up Information

Every installation requires a comprehensive start-up 
to ensure proper operation of the unit. As part of that 
process, the following checklist must be completed and 
information recorded. Starting up the unit in accordance 
with this checklist will not only ensure proper operation, 
but will also provide valuable information to personnel 
performing future maintenance. Should an issue arise 
which requires factory assistance, this completed 
document will allow unit experts to provide quicker 
resolve. Qualified personnel should perform start-up to 
ensure safe and proper practices are followed.

DANGER

Electric shock hazard. Can cause injury or death. 
Before attempting to perform any service or 
maintenance, turn the electrical power to unit to OFF 
at disconnect switch(es). Unit may have multiple 
power supplies.

WARNING

Use caution when removing access panels or other 
unit components, especially while standing on a 
ladder or other potentially unsteady base. Access 
panels and unit components can be heavy and 
serious injury may occur.
Do not operate energy core ventilator without the 
filters and birdscreens installed. They prevent the 
entry of foreign objects such as leaves, birds, etc.

CAUTION

Do not run unit during construction phase. Damage to 
internal components may result and void warranty.

SPECIAL TOOLS REQUIRED

•  Voltage Meter (with wire probes)
•  Amperage Meter
• Thermometer
• Tachometer
•  Incline Manometer or Equivalent

Start-Up Checklist

The unit will be in operational mode during start-up. Use 
necessary precautions to avoid injury. All data must be 
collected while the unit is running. In order to measure 
volts & amps, the control center door must be open, 
and the unit energized using a crescent wrench to turn 
the disconnect handle.

Check line voltage at unit disconnect
