Fixing the unit
■ Reserve sufficient maintenance space if possible.
■ If the unit is installed in a place where it snows in winter, proper
measures better be taken to protect the unit against snow and ensure
that the unit works properly.
■ Avoid installing the unit at below place as dirty, oil dirty, high salt and
high sulfide gas, installation at place with flammable gas is forbidden.
■ The groundwork should be made of concrete or supporting structures.
While designing the groundwork, you must fully consider the strength
of the floor, water discharge (the unit discharges water while working),
pipeline and wiring. If the floor is not strong enough, the unit might fall off and breakdown, even incur
bodily injuries.
■ Screw down the unit using anchor bolts so that it will not fall off in case of strong wind or earthquakes. To
avoid damages caused by strong wind or earthquakes, The unit must be securely installed at a proper
place to avoid direct hit of strong winds.
■ Depending on mounting conditions, operation vibration might pass through the groundwork and generate
noises in the floor and walls. Therefore, proper vibration dampening mechanisms (such as bumper
cushion, bumper frame etc.) should be in place.
■ Corners and edges should be properly installed. Otherwise, the unit might get unbalanced and cause the
grounding pins to bend. The unit might fall off and cause bodily injuries if it is not properly installed.
■ If pipes need to be installed under units, to make sure the pipes can go through the unit base, the
groundwork must be no less than 100mm.
