Installation Instructions

2INSTALL THE DRAIN

An external or an internal drain must be attached to the drain connector.

External Drain

Attach a 90° PVC elbow to the unit’s female 3/4″ NPT drain connector. Use the other end of the elbow to run a 3/4″ Sch.40 PVC pipe through the knockout holes of both the wall plenum and the architectural louver to the outside. Seal the gap between the plenum hole and PVC tube. See the Installation Instructions in the RAVAL1.

3DUCTWORK

Prepare the closet ductwork for later connection to the case.

The total flow rate (CFM) and external static pressure (ESP) available can be estimated from the chart below. Use these charts to select your fan speed setting. The collar on top of the case accepts standard 10″ duct.

Pull all duct tight. Extra duct slack can greatly increase static pressure.

CAUTION: Flex duct can collapse and cause airflow restrictions. Do not use flex duct for 90° bends or unsupported runs of 5 ft. or more.

To correct for 208 volts: 0.91

Your airflow should be balanced based on many factors, such as available ESP, room CFM, and ductwork. Consult an HVAC engineer for proper applications. External static pressure (ESP) can be measured with a manometer or pitot tube. Once this ESP is established, you can calculate the CFM using the above chart.
