Plumbing Connection - Hayward SHEER 500 Guide D'utilisation

PUMP SIZING:
In general, the pump should be sized to supply the SHEER one (1) gallon per minute per inch of width. For
example, a pump for a 24 inch SHEER should produce approximately 24 gallons per minute to provide a
wall of water. Ratios of flow apply, as can be seen on chart on page 4.
PLUMBING CONNECTIONS:
The most common installation of the SHEER is utilizing the main pool pump. A three way valve is installed
as illustrated below.
For multiple SHEERs, Hayward recommends that individual valves and lines be installed to allow balancing of the flow.
Two pumps can be connected to multiple SHEERs. This is the recommended installation when more than
70" of SHEER is installed.
NOTICE: Only filtered water should be used with this product. As noted in the figures above when a
separate pump is installed an additional properly sized filter is required between the pump and
the SHEER.
Hayward recommends the use of a plumbing trap in front of each SHEER. As illustrated this trap will allow
any large debris from construction to fall out of the flow steam, avoiding damage to the sheer. If the
plumbing line is accessible in final installation, it is recommended that the cap be removable.
If SHEER flow rate exceeds more than 40% of the filtered flow, a separate pump and filter system are
recommended.
The plumbing connection is a 1.5" US standard pipe socket. This fitting also accepts a 2" coupling.
NOTE: The water supply line should be flushed prior to plumbing the SHEER.
Plumb the unit using standard PVC cement. For rear mount units, minimize stress on the waterbox by
turning the plumbing down as close to the back of the wall as possible with a 90 degree elbow or sweep
fitting. Ensure that plumbing is sized appropriately for the required flow to the SHEER.
If more than 60" of SHEER length is installed, 2" plumbing, or larger, is recommended from the pump and
filter to the SHEERs.
