Following are suggestions for lowering system operating vacuum levels at an existing
pool or spa.
1. Reduce the pump size or reduce the pump impeller diameter
2. Check the main drain line for blockages
3. Replace the drain cover with another cover that has a higher open area
4. Replace return side nozzles with smaller orifices to slow down flow
For new construction or a remodel project, increase the diameter of the connector piping
and fittings where two or more main drains are employed, and increase the diameter of
the main drain suction line to reduce pipe velocity and running vacuum level. Minimize
the use of 90 degree elbows and other fittings that increase the system pressure drop.
Keep your pipe runs as short as possible.
Once the system vacuum level is set at 15” Hg or less, the system can be prepared for
SVRS installation.
SVRS UNPACKING INSTRUCTIONS
The VA2000 SVRS is packaged in a corrugated box with polystyrene upper and lower
inserts to protect the unit from damage during shipment. The product serial number is
located on the top of the box, and on the upper back side of the unit (ARL Number).
Carefully open the top of the box and note that the spanner key is housed in the
polystyrene insert – Do not lose or misplace the spanner key. Remove the upper insert
after stowing the spanner key and lift the unit by grasping the tee at each end.
DO NOT
DROP THE UNIT!
The Installation Instructions, DVD and Quick Installation Guide
are located in the box stowed between the box and the lower polystyrene insert.
If the outer package appears to have been damaged during shipment, carefully inspect the
unit. Closely inspect the vacuum gauge for possible damage in shipment; if the vacuum
gauge is damaged or in need of replacement it can be ordered by calling the factory. The
gauge incorporates a ¼” tapered pipe thread end connection which is installed into a
stainless steel gauge bushing. The gauge and the bushing are threaded together at the
factory with an anaerobic sealant. This sealant hardens and makes the separation of the
two parts difficult. The gauge bushing has external straight pipe threads and is threaded
into the main body of the unit with a non-hardening sealant. The gauge and bushing
together can be easily unthreaded from the main body by rotating the bushing counter
clockwise until it is free. The bushing can then be placed in a bench vise and removed
from the gauge.
SVRS INSTALL REQUIREMENTS
Though the SVRS (Safety Vacuum Release System) is easily installed, Vac-Alert
TM
highly recommends that a licensed contractor or service company install the SVRS.
When you properly install a Vac-Alert
TM
SVRS, you are providing an important
layer of protection against dangerous body and limb entrapment situations. This
system is not an effective defense against hair entanglement. This device may
mitigate evisceration. The Model VA-2000 SVRS unit shall only be installed in
