Installation Instructions

Series 2000B/LF2000B

Indoor Installation

Ames Series 2000B/LF2000B Double Check Valve
Check local codes for installation requirements. Pipe lines
should be thoroughly flushed to remove foreign material
before installing the unit. A strainer should be installed as
shown, ahead of backflow preventer to prevent disc from
unnecessary fouling. Install valve in the line with arrow on
valve body pointing in the direction of flow.

For indoor installations, it is important that the valve be easily
accessible to facilitate testing and servicing. Do not install in a
concealed location.

!

CAUTION

Do not install with strainer when backflow preventer is used
on seldom used water lines which are called upon during
emergencies, such as fire sprinkler lines, etc.
It is important that Series 2000B/LF2000B be tested
periodically in compliance with local codes, but at least once
a year or more often depending upon system conditions.
Regular inspection, testing and cleaning assurs maximum life
and proper product function.

NOTICE

Fire Protection System Installations: The National Fire Protection
Agency (NFPA) Guidelines require a confirming flow test to be
conducted whenever a “main line” valve such as the shutoff valves
or a backflow assembly have been operated. Certified testers of
backflow assemblies must conduct this test. The trim valves of the
detector meter bypass line, on assemblies so equipped, should be
shut off during the confirming flow test. When the test is completed
the trim valves must be retuned to a fully open position.

Parallel Installation Consult Local codes for Approval

Two or more Series 2000B or LF2000B smaller size valves may
be piped in parallel (where approved) to serve a larger supply
pipe main. This type of installation is employed whenever it is
vital to maintain a continuous supply of water/where interruptions
for testing and servicing would be unacceptable. It also has
the advantage of providing increased capacity where needed
beyond that provided by a single valve and permits testing
or servicing of an individual valve without shutting down the
complete line.

For two valve installations the total capacity of the devices
should equal or exceed that required by the system.

The quantity of valves used in parallel should be determined
by the engineer’s judgement based on the operating
conditions of a specific installation.

Servicing the First and Second Check Valves

NOTICE

Before servicing be certain water is turned off or shutoff valves are closed

1. After removing the cover, remove the retainer for the body bore. The check valve
modules can now be removed from the valve by hand or with a screwdriver.

Note: For Series 2000B or LF2000B sizes 1⁄2" – 2", the seats and springs of the first
and second check modules are not interchangeable. The heavier spring and smaller
diameter seat belong with the first check module.

2. The check seats are attached to the cage with a bayonet type locking
arrangement. Holding the cage in one hand, push the seat inward and rotate
clockwise against the cage. The seat, cage, spring and disc assembly are now
individual components.

3. The disc assembly may now be cleaned and reassembled or, depending on its
condition, it may be discarded and replaced with a new assembly from the repair
kit. O-rings should be cleaned or replaced as necessary.

4. Reassemble the check valve module in the reverse order. Check modules are
installed in the valve body with the seats facing the valve inlet. The modules must
be securely in place before the retainer can be replaced. On the 3⁄4" – 1" size, this
retainer may have to be tilted slightly into place. Replace cover.
