5.1 Requirements
For a proper function of the blast machine, a sufficient air supply is necessary (see table 2).

5.2 Set-up for initial installation or reinstallation
On an even and firm ground.
(2) Install an air supply for working
pressure indicated on pot.
− Place compressor upwind near blast machine (
contaminated air should enter compressor).
− Start compressor and bring it up to operating temperature (5
to 10min.). Only use compressors whose rating does
exceed the maximum working pressure of the pot!
− Attach airline
(appropriate dimension) with all necessary
gaskets in place to air outlet of compressor and safety lock
couplings.
Escaping air is dangerous and lowers
efficiency!
− Carefully open air valve of compressor to blow debris and
moisture out of attached airline.
− Close air valve.
−
Install an appropriate coupling to air inlet of blast machine
(safety coupling).
− Connect airline to blast machine and safety lock it.
− For trouble free blasting we recommend an air supply free of
oil and water (air cooler with cyclone and automatic drain).
(3) Attach blast hose and nozzle to
blast machine.
− Check gasket of coupling for wear.
− Connect blast hoses to length needed (All gaskets
in place!), attach them to blast machine and safety lock them.
− Choose an appropriate nozzle and attach it to nozzle holder
(4) Install a deadman handle and
− Pneumatic remote control:
