8.2 PLANNNING THE INSTALLATION
8.2.1 Before installing the Digital Nano/Nano+:
1) Determine everything needed for installation is on hand.
2) Determine where the Manifold Assembly will be plumbed.
3) Identify a suitable mounting location for the Digital Nano/Nano+ close enough, less than 12’
(3.6 m), to ensure that the cell cord and Tri-sensor cord will reach the manifold components.
Plan the routing for the cell and Tri-sensor Cables.
4) For the optional retractable pool cover installations with the Digital Nano/Nano+ models. (The
863A Expansion Board must be purchased and installed.)
a) Procure/Install dry contact cover position switch in retractable cover controller as needed.
b) Plan cable (not provided) run from cover position switch to Digital Nano/Nano+.
5) Determine whether the input voltage for the Digital Nano/Nano+ will be 110-120 Vac or 220-240
Vac.
6) Plan wire runs and wiring connections for source power.
7) Determine origination point for the Digital Nano/Nano+ control center power feed:
a) Directly from a circuit breaker. (Circuit breaker is used to power the Digital Nano/Nano+
and circulation pump.)
b) From an external timer or an electronic controller. (Digital Nano/Nano+ is to be wired to
the same location as the circulation pump; the Digital Nano/Nano+ is activated when the
circulation pump is energized.)
8.3 CHECK PARTS
Before attempting the installation, verify the following items have been included with the Digital
Nano/Nano+:

Split gland – ½” (when equipped with 863A Expansion Board. Comes with
optional kit #STK0156)
Metric PVC adapters (2” spigot x 63 mm socket) (only with metric manifold
models)
