Frost protection of the pump and pipeline.
If the system should be shut down for the winter, make sure that it is frost protected. It is almost
impossible to drain all the water from the system, so instead, fill it with anti-freeze windshield
washer fluid (Min. approved for -21°C)
You will need about 1 liter of anti-frost fluid per 10 meters of pipe + a some extra for pumps, filters
etc.
AMP 48 remote wi-fi control for service, can with success be used for this job.
1.
Empty the filter house and insert a new cartridge filter.
2.
Arrange a tank with a higher level than inlet to the pump (It can be a pressure tank or a
separate low-pressure pump)
3.
Put the ¾” low pressure hose down in the tank, ready for water to the pump (no air inside
the hose)
4.
Make a manual start of the pump, be sure the pump works OK and makes the right pressure
without any disturbing sounds.
5.
Open the end of the high-pressure pipe – one by one if more pipelines.
6.
Start the pump and stop again when anti-freeze fluid comes out of the end of the pipeline.
Close the end of the pipeline and proceed to the next pipeline and redo the step – when all
pipelines are filled with anti-freeze fluid continue to the next step.
7.
Ensure that the end of each pipeline is closed properly
8.
Start the pump with normal pressure and let all the nozzles spray minimum 30 sec.
The system is now frost protected.
In the springtime or when you are sure to avoid freezing the system, make the same again, but this
time with normal water directly from the pipeline, instead of anti-frost fluid.
Check the pump and pipeline for errors. Change the oil in the pump (SAE 15/40) and the system is
now ready for a new season.
