Plumbing Considerations.
Cold water supply.
General
The Electrode Boiler range of units is capable of
operating with a range of water quality raw mains.
The water supply should be within the following
limits :-
Hardness 50 –500 ppm
Conductivity 80 – 1000
µ µ
S/cm
Silica 0
Pressure of between 1 - 8 bar.
Water Supply rates
1.2 l/min

V60 VP40

5.0 l/min V80 VP80
Do’s
Do install a stop-valve/Shut-off valve and a strainer
close to the unit.
Do provide a water supply with sufficient pressure
and pipe size to ensure an adequate flow rate to
all units connected to the system.
Do use the water connection with nylon nut
provided.
ALL Dimensions in mm
Don'ts
Don’t use a wrench or other tool to tighten the water
supply connection - the nylon nut and rubber
washer provided, should only require tightening
by hand to effect a seal. If water seepage occurs,
undo the nut to wipe the washer clean and re-
seat it.
Drain connection .
General
Do's
Do
ensure metal drain and supply water pipework is
grounded electrically close to the unit (a
ground/earth stud is positioned on the underside
of the cabinet).
Drain capacity per cylinder
= pump discharge rate of max 16.8 l/min at 50 Hz.
Power supply 17.2 l/min at 60 Hz.
Do’s
Do
use copper or plastic pipe rated for 100
o
C.
Do arrange to discharge drain water from the unit
into a trapped and vented drain at a position
where flash steam rising from the drain line vent
will not pose a problem for the Vapac or other
equipment.
Do provide adequate fall for the drain pipework to
alow free flow of water drained from each unit.
Do ensure drain line pipe size will accommodate
water being drained at the same time from all the
Vapac units which are connected to it.
