1.3 Plumbing Considerations.
1.3.1 Cold water supply
.
General
The Resistance Heater range of units is capable of
operating with a range of water quality raw mains or
de-mineralised/de-ionised. The water supply should
be within the following limits:-
Conductivity 0 – 1000µS
PH 7.3 – 8.0
Silica
0
Pressure of between 1 - 8 bar.
Maximum chloride level 170 ppm
Water Supply rates
1.70 l/min

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.

De-mineralised < 50
De-ionised 50 – 100 < 80
Softened 100 – 200 80 – 100
Potable (Low conductivity) 200 – 300 100 – 150
Potable (Med. conductivity) 300 – 500 > 150
Potable High conductivity > 500
Generally the water type will be selected by the
conductivity levels, however they should be
modified as shown, e.g. conductivity of 75µS and
chlorine level of 85 ppm the correct setting is
Softened”.
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.
1.3.2 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
allow 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.
