NOTES: 1. KW heating values are based on voltages shown
below. Units will operate satisfactorily at N.E.C. standards
voltages
with slight reduction in heating capacity . + 208,240 or 480 V.3 Ph. ++ 240 V.1 Ph or
208,240 or 480
V.3
Ph. * 240 or 480V.3 Ph. ** 480V.3 Ph.
2. To convert KW
to MBH multiply by 3.412. Air Temperature Rise = MBH x 1000/SCFM x 1.08.
3. Use Total
Static pressure columns that will overcome total system resistance. Approximately
pressure drop for
components
and accessory items: heater element 3/8 "filter (dirty)1/4 " , intake hood 1/8 ,
bird screen 1/8",
discharge
louver, 1/8". Damper resistance may be ignored.
4. Refer to fan
curves in bulletin SB-1 for blower RPM and brake horsepower.
5. Maximum KW per
sq. foot - 28.98 KW per U.L.
6. NA - Not
Available. CHO - Contact Home Office.
TO
SIZE THE OPTIONALMAIN DISCONNECT SWITCH:
Add amps from ITEM A, B and C from the table below, then multiply by 1.25 |
