CAUTION
After test operation is completed, check the items mentioned in
the clause 2 "2. Items to be checked at delivery" on page 3.
If the interior finish work is not completed when the test opera-
tion is finished, for protection of the air conditioner, ask the cus-
tomer not operate the air conditioner until the interior finish work
is completed.
If the air conditioner is operated, the inside of the indoor units
may be polluted by substances generated from the coating and
adhesives used for the interior finish work and cause water
splash and leakage.
To the operator carrying out test operation
After test operation is completed, before delivering the air con-
ditioner to the customer, confirm that the control box lid is
closed.
In addition, explain the power supply status (power supply ON/
OFF) to the customer.
