Refer to page 317. 15.5 APPLICATION DATA SAFETY PRECAUTIONS • Please read these “Safety Precautions” first then accurately execute the installation work. • Though the precautionary points indicated herein are divided under two headings.
FDU-H NOTICE All Wiring of this installation must comply with NATIONAL, STATE AND LOCAL REGULATION. These instructions do not cover all variations for every kind of installation circumstance. Should further information be desired or should particular problems occur, the matter should be referred to Mitsubishi Heavy Industries, Ltd. through your local distributor. WARNING BE SURE TO READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION.

Ceiling surface Air conditioner main unit. Additional silencer may be necessary where a particu5 Blow outlet Suction hole larly low noise is required.
FDU-H (d) When constructing drain piping for several units, position the common pipe about 100 mm below the drain outlet of each unit as shown in the sketch. Use VP-30 (11/4˝) or thicker pipe this purpose. (e) Be sure to provide heat insulation to hard PVC pipes of indoor placement. (f) Do not ever provide an air vent. (g) Avoid postitioning the drain piping outlet at a place where generation of odor may be stimulated. Do not lead the drain piping direct into a sewer from where sulfur gas may generate.
