2. Installation and operation

2.1 Installation

2.1.1 General assembly instructions

• Sufficient space for installation, maintenance and service
• Tighten all screw fittings if necessary during a pressure test or following the initial heating

2.1.2 General assembly instructions for protecting the pump

When installing the pump group, please also refer to the instructions of the pump manufacturer:
• Only install a pump shaft horizontally
• Note the minimum supply pressures: e.g. 0.5 bar at 95°C; e.g. 1.08 bar at 110°C
• Only operate the pump when filled and bled
• Do not additionally insulate the connection box (the pump electronics must be kept cool)

2.1.3 Installing on a heating circuit manifold

The pump group is installed on the flat sealing screw fittings of the heating circuit manifold. Secure the manifold appropriately to ensure it
is capable of taking the weight of the pump groups.
(Warning: this is only possible if the lower insulation shell can be attached afterwards from the rear. The combination with our heating cir-
cuit manifold provides sufficient distance from the wall.)
1. Remove the supply and return line from the rear insulation shell
– extend with additional accessories as required (e.g. screw fittings, heat flow meter)
2. Screw the pump group with flat gaskets to the installed manifold.
3. Establish the piping to the connections.
4. Attach the lower insulation shell from the rear
5. Engage the central insulation shell into the lower shell and attach the front hood

2.1.4 Installing on a wall

1. Remove the supply and return line from the rear insulation shell - extend
with additional accessories as required (e.g. screw fittings, heat flow meter)
2. Position the lower insulation shell on the wall and mark the drill holes.
Alternatively: Mark the drill holes according to the drawing.
3. Drill the holes (ø 10 mm) and knock in a rawl plug.
4. Guide the pump power cable through the lower insulation shell.
5. Mount the lower insulation shell on the wall using hexagon head
screws and washers.
6. Engage the supply and return lines into the lower insulation shell.
Secure them as required to prevent them from falling off.
7. Establish the piping to the connections.
8. Engage the central insulation shell into the lower shell and attach the
front hood
