INSTALLATION
RECEIVING
When the absorption chiller is
delivered, inspect it for transit damage.
Should any damage have occurred, do
not proceed with installation until the
Yazaki distributor has been notified and
any required remedial actions have been
completed.
Remember to properly plan the route
to the installation site. Also, keep in mind
when choosing the site, the unit will
someday have to be replaced, so be
mindful of permanent and semi-
permanent barriers.
