i) Insert the 3 bolts provided into the holes in the metal
flange and place the metal flange over the tapered glass
tube of the boiler – ensuring that the flat side of the flange
faces the boiler.
ii) Take the plastic insert and place this round the glass tube
and into the metal flange. Pull the flange and insert
towards the end of the glass tube so that they press onto
the glass.
iii) Place the rubber gasket over the heater coils and then
insert the heating element through the tapered glass tube
and into the boiler.
iv) Now secure the heater using the 3 bolts. Do not over
tighten.
4. Feed the electric cable of the heater through the hole in the
base of the support stand. Place the boiler and heater assembly
in the ‘cradle’ of the stand. Ensure the stopcock on the boiler is
facing to the front. Secure with the 2 straps provided.
5. Ensure that the sealing o-ring and stabilising o-ring are correctly
positioned, as shown in Figure 3. Fit the condenser WC48/M2
by mounting it onto the vapour tube of the boiler. Ensure the
distillate outlet tube of the condenser faces the front and the
cooling outlet faces parallel to the unit.
Location
The Merit Water Still can be wall or bench mounted. Select a
convenient location which has access to the following services:–
Electricity Supply
Before connection please ensure that the line supply is suitable.
The Merit Water Still W4000 is suitable for supplies rated at
3kW, 220-240V, 50/60Hz~ single phase.
W4000/Euro is suitable for supplies rated at 3kW, 200-240V,
50/60Hz~ single phase. Supplies should be fitted with a 30mA RCD
circuit breaker.
Water Supply
A cold water supply capable of providing a minimum flow rate of
60 l/hr. Ensure all water supplies are earth bonded.
Drain
A waste water drain located below the level of the still so that the
drain pipe can fall away straight without kinks or bends, to allow an
unimpeded flow. Ensure all drainage systems are earth bonded.
Reservoir
A distillate collection reservoir should be located beneath the still.
Assembly
Your Merit W4000 has been designed with ease of assembly
specifically in mind, but before commencing assembly please study
the illustrations and text to familiarise yourself with the general
lay¬out. During assembly, follow the sequence of instructions and do
not connect the mains electricity supply until directed.
