Prior to start-up, the fan should be rotated by hand to make sure that the impeller is not rubbing
anywhere and that it turns freely.
Using a voltmeter, test the input voltages as supplied to the disconnect switch. Refer to Digit 13 of the
unit Configuration Code to find the rated voltage. The supplied voltage must be /- 10% of the
rated voltage.
Units with 230VAC power source are shipped with the transformer wired for 208VAC. If the unit is re-
ceiving 230VAC, make sure the black primary-side wire on the transformer’s 208V terminal has been
moved to the 230V terminal.
Filters must be installed prior to fan start-up. Filters must be clean and butted tightly against each
other, allowing no air circulation around them. A total of four filter spacers must be installed with the
foam gasketing positioned toward the filter. One filter retainer is used for each set of three filters,
positioned as shown in the installation instructions.
Proper installation of foam gasketing inside the ERV is critical to proper operation. Inspect the gasket-
ing to make sure that it is present where indicated in the installation instructions and that it is in good
condition. There should be no gaps allowing air movement around the cores or the filters.
The optional spring-type motor vibration isolators are adjustable in height. The height adjustment is for
holding the fan assembly sled at a uniform height. Verify that the fan sled height is uniform at all the
spring-loaded vibration isolators if they are present.
Prior to shipment from the factory, sheaves are carefully aligned and belts are tensioned. Inspect the
motor mount to verify that it did not shift during shipment of the unit. Verify that belts are still properly
tensioned and that they track correctly in the sheaves.
During the construction and installation phases of a project, dust, dirt and debris will often accumulate
inside a unit. Thoroughly clean the inside of the unit by vacuuming and/or wiping metal surfaces with
a damp rag.
Ducts attached to the ERV must be firmly attached, sealed and supported in accordance with
installation instructions and SMACNA guidelines.
