Mitsubishi Electric MECH-iF-G05 Instructions For Installation, Use And Maintenance Manual page 78

It is important that there is no air in the water circuit and no sudden variations in pressure or any points below atmospheric pressure.
There must not be any sudden variations in the flow of water. When the machine is running, there must not be variations in the water
flow rate of more than 10 % a minute of the rated flow rate. For this reason it is advisable to install an independent pump unit for each
single evaporator with a circuit separate from the rest of the plant.
For the production of domestic water it is recommended to install an intermediate exchanger to prevent dirt, corrosion and pollution of
the water from any oxides. The minimum and maximum water flow rate specified in our data book cannot be used as nominal flow rate
of the unit. The water flow rate must always be as stated in the selection of the operating conditions of the unit.
The directions for installation set out above represent a necessary condition for the validity of the warranty. However, Mehits is willing to
examine any different needs, which must in any case be approved before the refrigeration system is started up.
