Requirements
„
Genuine Wacker Neuson Heat Transfer Fluid, or
„
Dowfrost HD 50 Heat Transfer Fluid
NOTICE: Use only factory-recommended Heat Transfer Fluid (HTF). Failure to do
so may damage the machine.
Important The procedure for routine filling of the HTF reservoir differs slightly from that when
a low level fault is encountered. If you are filling the reservoir during normal
operation, see topic

Background The HTF reservoir includes a sensor that will trigger the low-level shut-down device
to stop the machine’s function if the HTF falls below the minimum operational
capacity. During a low HTF level condition the following occurs:
„
The control panel low level fault light illuminates
„
Power is cut to the burner
„
Power is cut to the pumps
„
The low-level shut-down device “LOW WATER” light illuminates
