1 General safety precautionsInstaller reference guide4RZAG35~60A2V1BR32 split series4P540076-1A – 2018.11▪ Make sure the area is well ventilated. Do NOT block anyventilation openings.▪ Make sure the unit is level.Do NOT install the unit in the following places:▪ In potentially explosive atmospheres.▪ In places where there is machinery that emits electromagneticwaves. Electromagnetic waves may disturb the control system,and cause malfunction of the equipment.▪ In places where there is a risk of fire due to the leakage offlammable gases (example: thinner or gasoline), carbon fibre,ignitable dust.▪ In places where corrosive gas (example: sulphurous acid gas) isproduced. Corrosion of copper pipes or soldered parts may causethe refrigerant to leak.Instructions for equipment using R32 refrigerantIf applicable.WARNING▪ Do NOT pierce or burn.▪ Do NOT use means to accelerate the defrostingprocess or to clean the equipment, other than thoserecommended by the manufacturer.▪ Be aware that R32 refrigerant does NOT contain anodour.WARNINGThe appliance shall be stored so as to prevent mechanicaldamage and in a well-ventilated room without continuouslyoperating ignition sources (example: open flames, anoperating gas appliance or an operating electric heater)and have a room size as specified below.NOTICE▪ Do NOT re-use joints which have been used already.▪ Joints made in installation between parts of refrigerantsystem shall be accessible for maintenance purposes.WARNINGMake sure installation, servicing, maintenance and repaircomply with instructions from Daikin and with applicablelegislation (for example national gas regulation) and areexecuted only by authorised persons.Installation space requirementsNOTICE▪ Pipework shall be protected from physical damage.▪ Installation of pipework shall be kept to a minimum.WARNINGIf appliances contain R32 refrigerant, the floor area of theroom in which the appliances are installed, operated andstored MUST be larger than the minimum floor areadefined in table below A (m2). This applies to:▪ Indoor units without a refrigerant leakage sensor; incase of indoor units with refrigerant leakage sensor,consult the installation manual▪ Outdoor units installed or stored indoors (e.g. wintergarden, garage, machinery room)▪ Pipework in unventilated spacesTo determine the minimum floor area1 Determine the total refrigerant charge in the system (= factoryrefrigerant charge + additional refrigerant amountcharged).Contains fluorinated greenhouse gases21 1122 kgtCO2 eq1000GWP × kg==+kg=kg=GWP: xxxR322 Determine which graph or table to use.▪ For indoor units: Is the unit ceiling-mounted, wall-mounted orfloor-standing?▪ For outdoor units installed or stored indoors, and field pipingin unventilated spaces, this depends on the installationheight:If the installation height is… Then use the graph or table for…<1.8 m Floor-standing units1.8≤x<2.2 m Wall-mounted units≥2.2 m Ceiling-mounted units3 Use the graph or table to determine the minimum floor area.010 2030 4050 6070 8090 100110 120130 140150 160170 180190 200210 220230 240250 260270 280290 300310 320330 340350 360370 380390 400410 420430 440450 460470 480490 500510 520530 5405501.822.22.42.62.833.23.43.63.844.24.44.64.855.25.45.65.866.26.46.66.877.27.47.67.81.843 7.9568.0Amin (m2 )Floor-standing unit (c)Wall-mounted unit (b)Ceiling-mounted unit (a)m (kg)
