	REQUIREMENTS

Proper installation/ ducting is extremely important to ensure maximum performance. Use a qualified and trained installer.

DUCTING

•Check with a qualified and trained installer or local codes for makeup air requirements, if any.

•Max. duct run

o For 1,200 CFM—50’ (15.2 m)

o For 1,500 CFM—75’ (22.9 m) o Duct run length is for

general reference only; for longer duct runs, increase duct size and contact a qualified and trained installer.

o The 1,500 CFM ventilator should be used with longer duct runs.

o Straight runs and gradual turns are best; for example, each 90° elbow is equivalent to 5 – 10 feet (1.52 – 3.05 cm) of straight run.

•10” duct run for 900 – 1500

CFM

o Never use flexible duct; it creates back pressure/air turbulence and greatly reduces performance.

ELECTRICAL

• Hardwire direct with two-wire with ground

• 120 VAC/60 Hz
