How to choose water treatment:– 4 tests:

– pH– Chloride (ppm) related to corrosion– Conductivity (μS/cm)– Hardness (ppm)

– Water conductivity: the correct range is 50 ÷ 2000 μS/cm

< 50 μS/cm: boiler overfilling

> 2000 μS/cm: boiler can work in dry condition, false detection of water.

CONDUCTIVITY

Electrical Conductivity is the ability of a solution to transfer (conduct) electric current. It is the reciprocal of electrical resistivity (ohms). Therefore conductivity is used to measure the concentration of dissolved solids which have been ionized in a polar solution such as water. The unit of measurement commonly used is one millionth of a Siemen per centimeter (micro-Siemens per centimeter or µS/cm).

This is also commonly referred to as “MEGA-OHMS”.

AOS OVEN RANGE: INSTALLATION DRAIN SYSTEM : AIR BREAK

ONLY LEVEL A OVEN

The oven drain circiut has a device call AIR BREAK in order to avoid the possibility of a back flow into the cavity from drainage. ONLY the MAIN DRAIN MUST be connected The SAFETY DRAIN MUST BE SEPARATED FROM THE MAIN DRAIN.AIR BREAK device has a inspection hole that can be used to maintain it clean.
