Table 31 — Accessory/FIOP Static Pressure (in. wg)* — 48/50PG20-28 Units
LEGEND *The static pressure must be added to the external static pressure. The sum and the evap-
orator entering-air cfm should then be used in conjunction with the Fan Performance
tables to determine blower rpm and watts.
Table 32 — Accessory/FIOP Electric Heat Static Pressure (in. wg) — 50PG20-28 Units
LEGEND NOTES:
1. Heaters are rated at 240 v, 480 v, and 600 v.
2. The static pressure must be added to external static pressure. The sum and the evapo-
rator entering-air cfm should then be used in conjunction with the Fan Performance
table to determine blower rpm, bhp, and watts.
Table 33 — Fan RPM At Motor Pulley Settings* — 48PG20-28 Units
*Approximate fan rpm shown. NOTE: Factory pulley speed setting is at 3 turns open.
