Installation; Installing The Template Box; Mounting The Appliance; Pump Heads - Baxi MS THINK+ Installation Instructions Manual

2. INSTALLATION

The appliance must be installed inside the template box, supplied separately.
Ensure that the model of the template box is correct.

2.1 INSTALLING THE TEMPLATE BOX

The template box must be fitted into the wall in a niche created for the purpose and blocked with special rag bolts at the sides.
Make sure the installation allows easy access for maintenance. The door and the white frame must be removed and fitted only
at the end of the installation phase (check that the key for opening the door is supplied with the box). The frame can be depth-
adjusted by using the 4 butterfly nuts located in the side guides. In this way it is possible to rest the frame on the plaster and
remove it if the wall has to be painted. Install the system, starting from the position of the water inlets present on the lower and
upper bars of the template (recess in the box: 30 mm). We recommend installing the box under or close to the boiler. It is advisable
to fit shutoff cocks (G3/4") on each inlet (available as accessories) to allow maintenance work, if required, without having to drain
the entire heating system.

2.2 MOUNTING THE APPLIANCE

After completing all masonry work, fix the MS THINK+ appliance inside the template box and make the hydraulic connections (for
the key to the connections and the hydraulic diagram see SECTION A at the end of this manual). Before fixing the module, make
the holes in the back wall to insert the Ø 10mm fixtures (use the holes in the template box as a guide). Then secure the module
with the supplied screws.
