Step 5
• Fill and pressurise the unit with water
BEFORE switching on.
Critical: Switching on the unit
without water will damage it.
• Turn on the power supply. The
Hotlogic control system will

in the surrounding air, the fan and
compressor will turn on.
• There will be a delay of approximately
30 seconds from the time the main
power is switched on before the
compressor and fan begin operating.
