10.6.4 Installation and Safety Guidelines
The 2
nd
low probe’s length must be equivalent to the 2
nd
low water level in the boiler as recommended by the
boiler’s manufacturer; this length should match the commissioned 2
nd
low level of the capacitance probes or
external level sensing device.
The 2
nd
low probe can be cut to the required length using pression cutting equipment. If this is not available,
please order the exact probe length from Autoflame.
The 2
nd
low probe should not be installed in the same pot as the capacitance water level probes. Any
blockages in the line will affect the levels; therefore the 2
nd
low probe should be fitted in a pot with a separate
line to the water level probes line. If the water level probes are installed in a pot externally mounted to the
boiler as shown in section 3.5.4, the 2
nd
low probe can either be fitted in a separate pot, or internally
mounted pot directly into the boiler. If the water level probes are installed in internally mounted pots as
shown in section 3.5.4, the 2
nd
low probe can also be installed in an internally mounted pot directly into the
boiler.
