START-UP & OPERATION
START-UP
STARTING UP THE UNIT
• Inspect your installation to be sure all duct work
is correctly installed and sealed, that filters are
in place, and controls (if any) are connected.
• Shut and latch the door to the unit.
• Plug unit into 115 VAC outlet. It may start
immediately.
• Use control to turn on the unit. Check operation
of the control(s).
• Check that the unit’s safety interlock switch
turns off the unit when the door is opened.
VERIFYING UNIT PERFORMANCE
AIRFLOW
Airflow should be occurring in both airstreams. Sometimes the easiest place to confirm that air is moving
is at the external wall caps.
If exact airflow is critical, it may be desirable to permanently install flow measuring stations and
manometers. These can also be used to determine when filters should be cleaned or changed.
Use Static Taps to Measure Aiflow Rates
See "Cross Core Static Drop" in MEASURING AIRFLOW table on page 13.
Use Damper to Balance Air Flow to Desired Rates, if necessary
The ERV's blower motor are well suited for volume control by dampers on the inlet of the unit. One
balancing damper is provided in the unit parts tray.
NOTE:
The unit is considered balanced if the
difference between the two airflows is not more than 10 CFM.
After measuring the airflow of the unit, the balancing damper may be used to balance airflow if desired.
Place the damper between the duct collar and the unit for the RA (Through Wall) / OA (Duct Hung)
airstream.
NOTE:
Install the damper as shown in Figure 8 below.
Slowly move the damper further into the duct until the desired airflow is recorded. Secure the damper
in place using 1/8" tek screws (provided).
NOTE:
Drilling through the case while the unit is running may
cause metal shards to be drawn into the unit.
