4.5.6. MULTIPLE MACHINES IN LINE SIMPLE PHASE
When multiple single phase machines are connected to the same electrical network, it is necessary to connect
the machines according to fig. 4.5.6. The phase of the frequency control and motor which is connected
to the terminal inside the machine, has to be connected alternatively for the first machine with the first phase
L1 of the network, the second machine with the second phase L2, ... The fourth machine must again be
connected to the first phase L1. This assures a better load of the electrical network.

WATER HARDNESS
It is advisable to contact the water supplier for information concerning the properties of the water in your
area. Good wash results are dependent also on the water hardness. For medium to very hard water,
consideration should be made to make the water softer.
Only in some cases is the use of hard water desirable, such as adding softener in the linen.
The soap supplier can help you with making the right decisions concerning hard water, soft water, washing
programs, type of soap and other related items to have the best wash results.
