Caution
Any parts you use for repair must be listed on the servicing parts
table specific to the model.
Using unlisted parts could result in a recurring fault or fire.
Inspect ground connections and rework them as needed.
An improper ground connection could result in an electric shock.
Replace the installation base and mounting frames if they are
found deteriorated due to corrosion or some other reason.
Otherwise, the unit may fall, possibly resulting in an injury.
Never fill any refrigerants other than R-410A refrigerant.
This machine has been designed and manufactured as a
specialized unit for R-410A refrigerant.
If a different type of refrigerant other than R-410A refrigerant is
used, a mechanical fault, malfunction and failure may result,
which could cause a serious safety hazard.
The filled refrigerant type is described on the machine nameplate.
