2.10 QUICK DISCONNECT COUPLINGS -continued
Use care when connecting coupling to avoid getting dirt, sand and
debris on coupling mating surfaces or in hoses. To prevent leaks and
ensure tight connections, make sure gaskets are installed in all fe
male quick disconnect couplings.
(1) Lift locking arms (2) up and away from female coupling (3).
(2) Position male coupling (4) in female coupling (3).
(3) While holding couplings together, pull locking arms (2) back and down against female coupling
(4) Test coupling connection by pulling on connected hoses(1 and 5). Hoses should remain securely
Do not disconnect hose couplings while water system is pressurized.
Hose ends may whip, causing injury to personnel and damage to
(1) Pull locking arms (2) up and away from female couplings (3).
(2) Disconnect female couplings (3) from male couplings (4).
ASSEMBLY AND PREPARATION FOR USE.
Site Selection and Preparation.
Select a level, debris
To avoid injury,
Place one 125 GPM
free area. Site must be large enough to contain all system components.
two personnel are required to position 125 and 350
pump (discharge pump) at water source. Position pump so that female
quick disconnect coupling points toward water source.
Place 350 GPM and 125 GPM discharge pumps in position with female couplings facing toward
water tank installation site and male couplings toward site chosen for water distribution.
Prepare 125 GPM pumps for use in accordance with TM 5-4320-304-14 or TM 10-4320-309-14.
Prepare 350 GPM pump for use in accordance withTM5-4320-226-14.
