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 pressure 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 over tighten 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.

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.

being drained at the same time from other equipment
connected to it.
