SELECTION OF LOCATION
The units are designed for indoor installation and should
be installed in a location that meets the following
requirements:
1. The foundation is strong enough to support the
weight of the unit and the floor is flat to prevent
vibration and noise generation.
2. The space around the unit is adequate for
servicing.
3. There is no danger of fire due to leakage of
infiammable gas.
4. Select the location of the unit in such a way that the
sound generated by to the unit does not disturb
anyone.
5. Ensure that water cannot cause any damage to the
location in case it drips out the unit.
NOTE Pull-down operation is restricted to one
hour maximum.
INSPECTING AND HANDLING THE UNIT
At delivery, the unit should be checked and any damage
should be reported immediately to the carrier claims
agent.
When handling the unit, take into account the following:
1. List the unit preferably with a crane and belts in
accordance with the instructions on the unit.
The length of the ropes (1) to be used for lifting are
4 m minimum each.
2. The unit is shipped with wooden beams (2) under it,
these have to be removed before installation.
NOTE Try to reduce the drilling in the unit to a
minimum. It drilling is impreventable,
remove the iron filling thoroughly in order
to prevent surface rust.
