2.8 Adjustable feet
Ensure the cylinder feet are wound out to pro-
trude at least 10 mm. from the bottom of the
product. Adjust the feet to ensure the product
is plum and level when placed in its final location.
2.9 Pipework
The product is designed with a 22 mm. cold wa-
ter inlet connection at the bottom, and a 22 mm.
hot water outlet at the top. Before connecting
the cold supply, flush the cold supply pipework
of all flux and debris.
2.10 Vessel connections
Fit the expansion vessel and bracket on a suit-
able wall close to the cylinder. Check the expan-
sion vessel(s) connections are tight.
2.11 Combination valve
Fit the valve.
2.12 Cold mains supply
Connect the cold mains supply (1) to the cold in-
let connection of the cylinder (7) and fit a drain
valve at lowest point of cold supply pipe (6).
Make the connection of multibloc valve on cold
supply pipework, see illustration. If secondary
return is required, fit via a Tee piece in the cold
feed pipe to the cyinder (7).
2.13 Hot water outlet
Connect the hot water distribution pipe to the ø22
mm. hot water draw off (12) on top of cylinder.
2.14 Balanced cold water supply (optional)
If no balanced cold supply is required, tighten
the supplied blanking cap.
If a balanced mains pressure cold water sup-
ply is required to a shower or bidet (over rim
type only , ascending spray type requires type
AA, AB or AD air gap), remove blanking cap
and connect to the shower or bidet cold sup-
ply (2) on the combination valve. Major shower
manufacturers advise fitting a mini expansion
vessel in the balanced cold supply pipework to
accommodate thermal expansion and prevent
tightening of shower controls.
