2. Installing the product
2.1 Mechanical installation
2.2 Tank mounting
CAUTION
Hot or cold surface
Minor or moderate personal injury
- Make sure that no one can accidentally
come into contact with hot or cold
surfaces.
The pump is designed for tank mounting in vertical
position. The pump is positioned in a hole cut into
the cover of the tank (upper side) and is secured to
the tank by four hexagon head screws through the
holes in the mounting flange. We recommend that
you fit a sealing gasket between the pump flange
and tank.
MTH pumps must only be mounted
vertically.

pump.
