MAINS WATER:
Connection from mains water is normally by a 10 or 12mm diameter reinforced pressure
hose similar to that used on a domestic washing machine or dish washer. This hose is
supplied with the machine. A fine mesh water strainer should be installed to prevent foreign
matter lodging inside the various solenoid valves.
DISTILLED WATER: (Floor models only)
The source of distilled water is usually gravity fed from the laboratory water still on the wall,
so the supply pressure is very low. For gravity feed, the still should be mounted at least 1
metre higher than the Mash Bath so the head pressure is sufficient. Because of the low
source pressure, the hose and the connection from the distilled water source should be
large in diameter. The distilled water may be supplied by a 12mm bore rubber hose and
hose clip to the hose tail provided on the machine.
In some labs, the distilled water will be supplied pumped under pressure. A smaller hose or
pipe can be used and the solenoid valve used in the machine is suitable for both low and
high pressure sources.
DRAIN:
The machine has a bath drain hose and a bath overflow hose. They require a waste drain
facility, about 50mm diameter, close to floor level so the large diameter drain hoses can be
inserted directly into the floor drain.
NOTE:
For fast, efficient bath draining, the water
falling under gravity must completely FILL the hose. If possible, the two drain hoses should
be inserted into the drain say 300mm or more so that the ‘falling’ of the water down the long
straight hose will draw’ the water quickly from the bath. If the drain hose is too large or too
small or simply passes into a sink, the bath will drain much more slowly.
The bath overflow hose is not so important to drain fast, but on floor mount machines, this
hose also the water coming from the heat exchanger (cooling coil) in the distilled water tank.
IMPORTANT NOTE:: The drain hoses must not be kinked, flattened or restricted.
