NOTES:
1 .Dotted line on construction filters indicates CFM where face
velocity exceeds manufacturer's recommended
maximum of 300 FPM. After startup, construction filters must be replaced with medium
velocity or high velocity filters.
2. Air pressure drop through electric heat is .05 inches WC.
3. Refer to Page 27 for pressure drop
through flexible horizontal discharge.
