Pipe installation
Pipe installation must be carried out in accordance with
current norms and directives.
The water heater must be fitted with the requisite valves,
such as a safety valve, shut-off valve, non-return valve
and vacuum valve (-Cu).
The water heater must be provided with a mixer valve,
which limits the temperature of outgoing hot water to
60 °C. If this valve is not fitted, some other measure must
be taken to prevent the risk of scalding.
Internal support bushes must be fitted when a plastic or
annealed copper pipe is used. An overflow pipe must be
routed from the safety valve to a suitable drain. The
overflow pipe must be the same size as the safety valve.
Route the overflow pipe from the safety valve, sloping
along its entire length and ensure that it is frost proof.
The mouth of the overflow pipe must be visible and not
placed close to electrical components.
The enclosed drain valve with corresponding plug is in-
stalled as follows:
1. Remove the compression ring and compression ring
nut from the drain valve.
2. Install the valve using the existing compression ring
and compression ring nut on the draining pipe.
3. Replace the compression ring with a plug on the
open part of the drain valve.
The coils in VPB 1000 must be connected in parallel (see
image below). The venting nipple, with corresponding
T-pipe connector, must be installed at the highest point
on the upper coil.
NOTE
Fit the cover discs before the pipe installation
is made.

Filling
Fill the water heater as follows:
1. Open a hot water tap in the system.
2. Open the shut-off valve on the incoming cold water.
This valve should then be fully open during opera-
tion.
3. The hot water tap can only be shut off when the
water heater is filled, which is when only water
comes out of the tap (initially an air-water mixture
comes out of the tap).
