Each SVRS unit is provided with a Vac-Alert
TM
Field Test Data Sheet that must be
completed.
Fill out this form and fax or mail it to Vac-Alert
TM
Industries as instructed on
the form. It is critical that this form be completed and all of the information requested
supplied.
The Vac-Alert
TM
SVRS must be routinely tested to ensure ongoing safe operation of
the unit.
It is required that the SVRS be tested, per the prescribed testing
procedures, prior to the start of each swimming season, and recommended
thereafter at least once per month while the pool or spa remains in use by the end
user.
IMPORTANT NOTICES
INSTALLER AND USER MUST READ!
1.
Locate the Vac-Alert
TM
SVRS on the main drain suction line
.
The SVRS must be mounted in the vertical position. All SVRS units shall be
field adjusted to site-specific hydraulic conditions. Once adjusted the SVRS unit
must be tested three times by simulating an entrapment event.
2. A fast acting, full-flow, full-port two-way valve, ball valve or butterfly valve,
installed within two feet of the SVRS unit, can serve as a test valve. A test valve is
an optional alternative to a pole-mounted test mat. Each Vac-Alert
TM
SVRS unit must
be tested three (3) times to ensure proper adjustment and operation. Where a hydro-
static valve is present, the SVRS must be mat tested.
3. This SVRS unit must be routinely tested. The Vac-Alert
TM
SVRS unit must be tested
at the start of each swimming season, and recommended thereafter at least once per
month while the pool or spa remains in use by the end user.
4. For multiple pump systems, one (1) Vac-Alert
TM
SVRS unit is required for each pump
plumbed to a dedicated main drain suction line.
5. The Vac-Alert
TM
SVRS unit is rated for suction vacuum levels up to 15 inches of Hg
(mercury). For vacuum levels above 15 inches of Hg, see Initial System Preparation
instructions for recommendations on how to lower system operating vacuum level.
6.
WARNING:
Check valves and obstructions located between the main drain(s) and
the Vac-Alert
TM
SVRS must be removed from the suction system. Do not install
(must be removed from existing systems) a check valve in a main drain line between
the main drain(s) and the SVRS. A check valve may be installed in the main drain
suction line between the SVRS connection tee and the circulation pump. Also, check
valves may be installed anywhere on the return side of the pump. The Vac-Alert
TM
SVRS may be used with hydro-static valves, but a mat test of the SVRS operation
is required if a hydro-static valve is present.
