(23) Open the fire hydrant's main valve as needed.

(24) Control flows from the downstream valve, always opening it slowly to

avoid overspeeding on start-ups.

POSITIVE DISPLACEMENT METERS

At your request, these meters may have a non-return valve installed in the inlet port.

This valve will not allow pressures caused by thermal expansion to pass to the water

system's side of the meter. Take particular care that the meter is installed with the

direction of flow as indicated by the arrow cast in the meter case. Check your local

codes for pressure relief requirements. AMCO Water Metering Systems Inc. assumes

no responsibility for damages.

At your request, these meters may have a plastic main case. Plastic meter cases will

not conduct electricity. Check your local codes for grounding requirements. AMCO

Water Metering Systems assumes no responsibility for the electrical grounding of its

water meters.

At your request, these meters may have a frost protection device. Take particular care

to install these meters in a location where water damage will not occur if the frost

device releases or functions. AMCO Water Metering Systems assumes no

responsibility for damages.

FIRE HYDRANT METERS

This meter has a restrictor plate installed in the outlet port. A restrictor plate will

suppress the flow capacity of the meter and protect it from overspeeding when water

throughput flows to atmosphere. Take particular care to install and start-up the meter

as recommended above. AMCO Water Metering Systems assumes no responsibility

for damages.

At your request, this meter may have a check valve installed in place of the restrictor

plate. This valve will not allow pressures caused by reverse flow conditions to pass to

the water system's side of the meter. Take particular care that the meter is installed with

the direction of flow indicated by the arrow cast in the meter case. Check your local

codes for pressure relief requirements. AMCO Water Metering Systems assumes no

responsibility for damages.
