Equipment such as heaters, skimmers, and chlorinators require minimum flows to operate correctly. Refer to individual
equipment manuals for specific flow requirements.
After setting the pump speed(s), it is recommended you check that all other equipment/water features are functioning as
intended. For example, when running at a low speed for daily filtration, verify water is adequately flowing over the skimmer
weirs. Operate the pump at higher speeds for the shorter periods of time needed to operate a heater, water feature, etc.

Installation and Wiring
WARNING
– This product should be installed and serviced only by a qualified professional.
4.1.
Pump Location
Locate pump as close to pool as practical and run suction lines as direct as possible to reduce friction loss. Suction lines
should have continuous slope upward from lowest point in line. Joints must be tight (but not over-tightened). Suction line
diameter must equal or be larger than the discharge line diameter.
Though the pump is designed for outdoor use, it is advised to place pump and filter in the
shade to shield them from continuous direct heat. Select a well-drained area that will not
flood when it rains. Do NOT install pump and filter in a damp or non-ventilated location.
Keep motor clean. Pump motors require free circulation of air for cooling.
4.2.
Pump Mounting
Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base with
screws or bolts to further reduce vibration and stress on pipe or hose joints. The base must be level, rigid, and vibration
free.
Pump mount must:
Allow pump inlet height to be as close to water level as possible.
Allow use of short, direct suction pipe (to reduce friction losses).
Allow for valves in suction and discharge piping.
Be protected from excess moisture and flooding.
Allow adequate access for servicing pump and piping.

Note:
It is recommended that a minimum length of straight piping (shown as “L” in above diagram), equivalent to 5 pipe
size diameters, be used between the pump suction inlet and any plumbing fittings (elbows, valves, etc.).
When installing the VS pump, care should be taken to ensure proper pipe and equipment sizing to handle
the maximum flow required. It is recommended to set the maximum speed in order to not exceed the
maximum flow rate. See section 6.6 item #7.
