Unit Installation - Mitsubishi Electric QAHV Série Manuel D'installation & D'instructions

2. Unit Installation

Units should be installed only by personnel certified by Mitsubishi Electric.
• Securely fix the unit with bolts to keep the unit from falling down during earthquakes or due to strong winds.
• Install the unit on a foundation made of concrete or iron.
• Noise and vibrations from the unit may be transmitted through the floor and walls. Provide adequate protection
against noise and vibration.
• Build the foundation in such way that the corners of the installation legs are securely supported as shown in the
figure below. When using rubber vibration isolators, make sure they are large enough to cover the entire width of
the unit's legs. If the corners of the legs are not firmly seated, the legs may bend.
• The projecting length of the anchor bolt should be less than 30 mm (1-3/16 in).
• This unit is not designed to be installed using hole-in anchor bolts unless brackets are used to support the four
corners of the unit.
• The legs on the unit are detachable.
Warning:
• Be sure to install the unit on a surface strong enough to withstand its weight to keep the unit from falling
down and causing injury.
• Provide adequate protection against strong winds and earthquakes. Improper installation may cause the
unit to fall down, resulting in personal injury.
When building the foundation, take the floor strength, water drainage during operation, and piping and wiring routes
into consideration.
Precautions for routing the pipes and wires underneath the unit
When routing the pipes and wires underneath the unit, make sure that the foundation will not block the piping access
holes. Also, make sure the foundation is at least 100 mm (3-15/16 in) high so that the piping can pass under the unit.
