6. Set-up and Installation
6.1 Set-up
Inspect the packaging for damage and remove packaging preferable only at the installation site.
For the selection of the installation site, the tare weight of the storage unit (unit and insulator) including the fill-water
weight must be considered. The room has to be above freezing. For drainage, the water drainage pipe must be freeze
proof.
6.2 Connection
Refer to Diag.1 and Diag. 2.
6.3 Heater Installation
The installation of the heating circuitry is shown in Diag. 4. The heater installation can be according to the installation
diagram. This, however, varies according to operation. In addition, it must be assured that no air can collect in the
system. Therefore, an exhaust unit has to be built into the heating circuitry (31).
6.4 Hot Water Installation
6.4.1 Prior to installation check that the local conditions are compatible with the appliance design, especially that the
maximum working excess pressure of 145 PSI (10 bar.) can be maintained.
6.4.2 A steel or a copper pipe with insulation can be used for the hot water connectors. Copper pipe with insulation is
especially suitable because of its low friction and heat loss.
Required combination
Cold water pipeline Hot water pipeline
Copper pipe copper pipe
Steel pipe steel or copper pipe
Plastic steel or copper pipe
6.4.3 A safety group (28) must be installed into the cold water supply (27, Diag. 4). The order of the individual fittings
must be in accordance to local regulations.
6.4.4 The membrane safety valve (21) has to be set to 145 PSI (10 bar.) excess pressure and sealed. It can only be
installed into the cold water supply (27). The supply has to be thoroughly inspected prior to installation. Installation of dirt
filters or any other narrowing of the supply line to the membrane safety valve is forbidden.
The membrane safety valve (21) has to be easily accessible. Expansion water generated during the heating has to flow
visibly into a funnel and be drained.
Funnel and drainage pipe must be large enough to accommodate water drainage with a fully opened membrane safety
valve. The drainage pipe must be protected from freezing and must not lead outdoors.
The membrane safety valve (21) has to be set such that there are no water drips with the resting heater (storage water
being reheated).
Heavy dripping of the membrane safety valve on the outside of the warming operation can be caused by dirt in the valve
seat of water pressure that is too high. At excessive water pressure a pressure reducer (25) needs to be installed.
6.4.5 During installation all necessary screws outside of the flange area must be in order. This assures that the revision
flange can be maintained.
6.4.6 Drainage of the hot water tank (30) is via the drainage faucet (29) at the drainage connector.
6.4.7 The circulator can be attached to a separate socket across the thermometer. Drill the outer casing with a hole saw
∅ 50 where marked and remove insulation from the socket in that area.
For energy conservation, use of a circulator is not recommended.
