3 Operation
Note: Initial Startup must be performed by an Authorized Factory Technician.
3.1 Seasonal Startup
Media
a) Check all bolts and fittings for tightness. Initiate filter backwash.
Note: Stop backwash cycle before last vessel has completed cycle (about 4 minutes into last
vessel backwash) by de-energizing system at service disconnect on control panel.
Perform the following steps with the filter system isolation valves closed and power to
service disconnect secured.
b) Start to drain filter system through lower manifold drain valve. Note: Check filter gauges to
ensure pressure is reading zero before proceeding to next step.
c) Remove filter vessel cover. Inspect cover and cover gasket, replace if necessary.
d) Note: Drain water to top of sand then close drain. Inspect filter media . Sand should
appear clean and loose. Manually remove any debris from top of sand.
e) Level of sand in the filter vessel should be approximately 7.5 " – 8.5 ” from bottom of filter
inlet. If media level is below normal or appears other than loose sand, contact AmeriWater
800.855.5535.
Note: Media may appear colored. This condition is common and usually due to the presence
of iron oxide or organics in the system water.
f) If sand is at normal operating level and clean, refill vessel with water.
g) Replace filter access cover gasket and cover, and secure cover bolts.
