Precautions On Installation; Outdoor Unit Installation Diagram - Daikin 2MXL18QMVJU Installation Manual

Precautions on Installation

• Check the strength and level of the installation surface so that the unit does not cause
any operating vibrations or noise after installation.
• Fix the unit in place securely using foundation bolts, as in the figure. (Prepare 4 sets
of 5/16 inch (M8) or 3/8 inch (M10) foundation bolts, nuts and washers; all separately
available.)
• It is best to screw in the foundation bolts until their ends are 3/4 inch (20mm) from the
foundation surface.

Outdoor Unit Installation Diagram

CAUTION
• Do not connect the embedded branch piping and the outdoor unit when only carrying out piping work without connecting the
indoor unit in order to add another indoor unit later.
Make sure no dirt or moisture gets into either side of the embedded branch piping.
Refer to "7. Refrigerant piping work" on page 11 for details.
• It is not possible to have only 1 indoor unit connected. Be sure to connect at least 2 indoor units.
Where there is a danger of the
unit falling, use foot bolts, or
wires.
In sites with poor drainage, use
block bases for the outdoor unit.
Adjust foot height until the unit is
level. Otherwise, water leakage
or pooling of water may occur.
