Installation of washing machines

Good afternoon
I will install the washing machine:
1) connecting the washing machine drain to the sewer pipe;
2) connecting cold water to the washing machine;
3) install the washing machine on a level to avoid vibration;
4) trial run.
You need to already have a prepared sewer pipe for 50, a rubber adapter from 50 to 25, and a tap to shut off the cold water supply.
If the machine is new, then remove the transport bolts.
If possible, write to the chat, I may not be in the access zone.
