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

 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.
