8.5.c Flow Rates 20 – 70 gpm (76 – 265 L/min)
l
The manifold can be directly plumbed (vertical position) into the system.
l
If the flow rate for the system is less than 20 gpm (76 L/min), a larger pump must be installed (or steps
taken to improve flow rate).
l
For a variable speed pump, ensure the pump can provide sufficient flow at the low speed.
Flow Rates Exceeding 70 gpm (265 L/min)
l
A bypass must be installed on systems with flow rates exceeding 70 gpm (265 L/min).
l
Manifolds are to be installed in a vertical (upright) position ONLY.

8.6 Preparing the Pool Water
Installer please note - When properly sized to the site, the Pool Pilot
®
will meet the sanitizer
“maintenance” requirements of the pool / spa. The unit is not designed to chlorine shock treat or
build up a chlorine residual when starting with a zero or very low chlorine level.
Before starting the chlorinator, the water must be properly balanced and the chlorine level
adjusted to between 1 - 3 ppm (mg/L) free chlorine. More on adjusting water balance and start-
up chlorine levels follows below.
8.6.a Calculating Pool Volume
To determine the approximate number of gallons or liters in a pool or spa:
1. Determine the surface area.
2. Multiply the surface area by the average depth and the constant conversion factor of 7.5 to convert
cubic feet to gallons, or 1,000 to convert from cubic meters to liters.

Area = Length x Width

Gallons = area x average depth (ft

Liters = area x average depth (m

) x 1,000
