Airflow Measurements And Balancing; Maintenance; Bi-Monthly Maintenance - Venmar 6LC Installation, Operation And Service Instructions

Once installation is complete, the supply and exhaust airflows should be balanced. This will ensure proper operation and a good quality
installation.
A well designed duct system with properly sized duct runs and equal static pressure losses of both the supply and exhaust will aid in
balancing the unit. However, it will be necessary to take flow measurements with the proper equipment to ensure a balanced system.
Before proceeding with balancing, all windows, overhead doors and walk-in doors should be closed and exhaust systems should be
turned off.
