1. Turn off all electric heaters.
2. Push Pump Stop Button.
3. Turn off main power switch.
4. Shut sea water valve and open fresh water valve to flush the entire system with fresh water
for at least 15 to 20 minutes after each usage. This will flush out the heating system,
plumbing, valves, umbilical and most important, the breathing gas heat exchanger and the hot
water suit. If required, run the pump to ensure adequate flushing of the system pipework with
fresh water.
5. Shut the fresh water valve off. Open the drain valve and tank vent valve and allow the water
to drain from the system.
I
MPORTANT
During the flushing process ensure that the entire system is flushed out by momentarily
opening the venting valve and both dump valves.

AUTION
DRAIN SYSTEM
To prevent damage due to freezing of the water in the system it is
important to drain all the water before storing the unit. In warmer
climates draining the system may not be necessary. However,
flushing the unit remains necessary prior to storage, especially to
prevent corrosion of stainless steel components by stagnant
seawater (MIC or Microbiologically Induced Corrosion).
