DO remove the cylinder to gain access to the
mounting holes in the back of the steam section.
DO use M6 projecting type wall bolts or equivalent
to mount the unit in position.
DON'Ts
DON'T install the unit close to sources of strong
electromagnetic emissions e.g. variable speed lift
motor drives, KVA transformers, etc.
DON'T mount unit in an unventilated enclosure.
DON'T mount in a position requiring ladder access
to the unit.
DON'T install the unit behind a false ceiling or other
situation where an unusual malfunction (e.g. water
leak) would cause damage.
DON'T install the unit in an area which will be
hosed down.
DON'T install the unit where the ambient air
temperature can exceed 35°C (95°F).
DON'T mount the unit inside a cold-room or other
place where temperature and humidity conditions
can cause condensation on electrical components.
DON'T mount the unit where the sound of a
contactor opening/closing and water flow in a pipe
would be unacceptable e.g. libraries, private

Plumbing - Cold Water Connections
DO's
DO connect only to normal town piped water supplies.
DO install a stop-valve/shut-off valve and a strainer close
to the unit.
DO provide a water supply with sufficient pressur e and
pipe size to ensure an adequate flow rate to the unit -
1.2 litres/min (0.3 US gal/min).
DO use the flexible water connection provided.
DO thoroughly flush through new pipework before
connecting to the unit.
DON'Ts
DON'T connect to a water supply that has been softened
using a salt exchange system (sometimes called base
exchange or ion exchange system).
DON'T connect to demineralized water supplies.
DON'T overtighten the water supply connection with a
wrench or spanner- a flexible connection with nylon nut
with washer is provided to allow a firm hand-tightening - if
water seepage occurs, undo the nut to wipe the washer
clean and then re-seat it.
Plumbing - Drain Connection
DO's
DO use copper pipe or plastic pipe rated for
1
OO°C (212°F).
DO arrange to discharge drain water from the unit into a
vented and trapped drain at a position where flash steam
rising from the drain line tundish 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 other equipment
connected to it.
General
DO ensure metal drain and supply water pipework is
grounded electrically close to the unit.
