18.4 OUTLINE OF OPERATION CONTROL BY MICROCOMPUTER This is same as FDUR heat pump series. Refer to page 306. 18.5 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. WARNING and CAUTION , those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the WARNING section.
NOTICE All Wiring of this installation must comply with NATIONAL, STATE AND LOCAL REGULATIONS. 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.
(2) Transporting and installing the unit (a) Transporting Front surface facing upward Request ¡ When transporting the unit to the final mounting location, keep it in its original packing as long as feasible. ¡ When the situation demands that the unit be unpacked for transportation, wrap using nylon sling and take care to ensure that the unit is not damaged. Note (1) Do not hold the unit by the air inlet grill, by the air outlet grill, or by any other plastic parts.
(4) Drain piping WARNING ¡ The drain must not be allowed flow into any drainage systems where sulfurous or any other types of poisonous gas may be present as it could result in these gasses passing to the interior of the air conditioned room. Request ¡ The drain piping should be insulated to prevent the occurrence of condensation. (This applies particularly to the indoor unit itself and the unit’s interior.
