OPERATION
The operation of the product is quite simple and is mostly automatic.
Please always remember that the product has hot surfaces. There is a danger of burns if
the surface is touched.
In the case of danger, separate the machine from the mains (pull the mains plug).
3.1
Switching on the product
The product is switched on at the pressure switch to setting “I” - “ON”. The product starts and the pressure tank
fills up. When reaching the switch-off pressure, the product turns off automatically.
Please watch closely that the maximum permitted operating pressure is not exceeded. The permitted operating
pressure is marked on the fitted pressure gauge with a red line.
If the permitted operating pressure is exceeded, you must switch the product off and separate it from the mains
supply (pull out mains plug). Inform the responsible qualified staff.
3.2
Switching off the product
Switch off the product to setting “0” - “OFF”.
3.3
Switching on the product after a power supply interruption
Advice:
The product will not start against pressure. Therefore the products are fitted either with
an expansion tank (1) and a mechanical vent valve (2) Figure 3 or with an automatic starter
valve.
Switching on machines with expansion tank and mechanical vent valve and machines with drying installation:
1. Switch off product at pressure switch.
2. Restart the machine at the pressure switch, after the air has been blown-off of the starting volume (this will take
approximately 5 seconds).
Machines with automatic starter valve:
If the product is fitted with an electric starter relief valve, the normally closed valve provides for the pressure free
starting of the product.
3.4
Pressure tank check
According to the regulations pressure receivers up to 25 l, corresponding to the pressure tank contents p x l < 200,
are allocated to group 1 of paragraph 8 classification and not subject to recurrent tests pursuant to paragraph 10.
The pressure tank conforms to the EU guidelines 87/404 EEC.
