Start-Up

o

  Rotate the fan wheels by hand and ensure no parts 

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

o

  Check the fan belt drives for proper alignment 

and tension (refer to Start-Up section for more 
information).

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).

o

  Install exhaust inlet motorized damper (see Unit 

Accessories 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.

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, bearings, drives, motor bases and 
accessories for tightness.

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 recovery 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.

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
