2-14. M20A1 SCPE USED IN AREA WITH HIGH CEILINGS.<br />
a. General.<br />
NOTE<br />
Pressure inside SCPE must be adjusted (para 2-8h) before reaching between 0.6 1.20 iwg.<br />
If liner of SCPE is inflated in areas where ceiling height is greater than liner height, some loss of usable floor<br />
area will occur as liner tends to assume a ball shape. Where a ceiling is higher than 12 ft., or where there is a false<br />
ceiling which will not bear the upward force of liner (about 600 lbs), there are two methods for maintaining liner shape.<br />
b. Sandbagging.<br />
(1) Ensure all vents from PE to shelter are open.<br />
NOTE<br />
You will need 12 to 14 sandbags, depending on weight of each bag. When room liner pressure is<br />
0.6 iwg, you will need 600 lbs of sandbags.<br />
(2) Place sandbags (1) (Item 2, App D) inside liner.<br />
(3) Place sandbags evenly along outer edge of floor.<br />
(4) Adjust vents to proper pressures (para 2-8).<br />
