TRD 604 - 72 hr :
The 310, 311,312, 313, 313a pressure swit-
ches are approved in dual mode or under the
code of "special construction requirements",
the solenoid valve RL (182) in the return line
is required.
TRD 604 - 24 hr :
The 310, 311, 312, 313, 313a pressure swit-
ches are designed in single mode. The sole-
noid valve RL (182) is built in if the return
flow pressure / ring line pressure exeeds 1
bar.
EN :
The 310, 311, 312, 313 pressure switches
are designed in single mode.
The 313a max. pressure switch is not availa-
ble. The solenoid valve RL (182) is required.
Electrical heating cartridges for the oil bloc,
the nozzle rod and the hoses are used with
heavy oil burner versions only.
