Technical and electrical specificationsRefer to the Engineering Data Book for the complete list ofspecifications.3. BEFORE INSTALLATION3.1. Precautions for R410A■ The refrigerant requires strict cautions for keeping the systemclean, dry and tight.- Clean and dryForeign materials (including mineral oils or moisture) should beprevented from getting mixed into the system.- TightRead "8. Precautions on refrigerant piping" on page 6 carefullyand follow these procedures correctly.■ Since R410A is a mixed refrigerant, the required additionalrefrigerant must be charged in its liquid state. (If the refrigerantis in state of gas, its composition changes and the system willnot work properly).■ The connected air handling units must be air handling unitsdesigned exclusively for R410A.3.2. Installation■ For installation of the air handling unit(s), refer to the air handlingunit installation manual.■ Never operate the air conditioner with the discharge pipethermistor (R2T), suction pipe thermistor (R3T) and pressuresensors (S1NPH, S1NPL) removed. Such operation may burnout the compressor.■ Be sure to confirm the model name and the serial no. of theouter (front) plates when attaching/detaching the plates to avoidmistakes.■ When closing the service panels, take care that the tighteningtorque does not exceed 4.1 N•m.3.3. HandlingAs shown in the figure, bring the unit slowly by grabbing the left andright grips.Place your hands on the corner instead of holding the suction inlet inthe side of the casing, otherwise the casing could be deformed.4. SELECTING INSTALLATION SITEThis is a class A product.
