3.2 Electric install
3.2.1
Electricity connection
The control power input is AC 220-240V,50/60Hz.Electricity wires should be place away from
probes to prevent interference.It is not recommended that the controller use a common
power input source with other electric equipment which may generate surge voltage which
can cause interference. A correct grounding connection which can prevent interference
between equipment as well. It is highly recommended that the controller and diffuser pump
are connected to the same on/off control so to prevent dosing during diffuser pump is not
under operating condition.
Caution
：
Wires must be connected to GFCI or RCD and the wiring should comply with
regulatory requirement for the region.
3.2.2
Probe install
During connect the controller with powers (SANITOZER, POWER, PH DOWN and PH UP), you
must make sure the power is disconnected. Probe wire should be as short as possible and
positioned far away from the power wire, pump, transformer or any other device which may
cause interference. Probe (ORP and pH) must be connected to the corresponding BNC
connector. Incorrect connection may cause probe or controller damage. pH and ORP probe
which provide by Emaux should be paired to use with the controller. Probes should be used
pair with Emaux probe holder. Probe holder can be install in; 1) main pipe (main line), or 2)
sampling pipe (bypass line) (recommended method). Fix the probe holder on the pipe, place
the probe into the holder sealing cap. Tighten the cap by hand only to avoid breaking the
probe. Do not use a wrench.
