Little Giant LG14AH Owner's Manual

OWNER'S MANUAL
Pressure Tank System
The pressure tank is a closed container. The durable steel shell is constructed in
a deep-drawn process for extra strength. Welding eliminates interior rough
spots and sharp edges, which prevents damage to the diaphragm. The tank
uses a membrane diaphragm to completely isolate compressed air from the
water. The tank is certified to NSF 61 for safe drinking water. An air charging
valve allows the installer to change the air pressure when the tank is empty.
The Little Giant pressure tank leaves the factory tested and pre-charged to 20
psi. Because air and water are permanently separated, an air volume control is
not required.
This product is covered by a Limited Warranty for a period of 5 years from the date of original purchase by
the consumer. For complete warranty information, refer to www.littlegiant.com/support/warranty/.
