See the capacity table inthe Engineering Data Book for details.2-2 Standard supplied accessoriesConfirm the following accessories are included. The storage locationof the accessories is shown in figure 1.NoteDo not throw away any of the accessories until installation is com-plete. They are needed for installation work.(Refer to figure 1)1. Clamps, Manuals, etc.2. Accessory pipes2-3 Option accessoryTo install the outdoor units, the following optional parts are also required.To select an optimum kit, refer to “6. REFRIGERANT PIPING”.• Outdoor unit multi connection piping kit• Refrigerant branching kit• Pipe size reducerMake sure that any separately purchased accessories are designedfor use with R410A.2-4 Technical and Electrical specificationsRefer to the Engineering Data Book for the complete list of specifications.2-5 Main componentsFor main components and function of the main components, refer tothe Engineering Data Book.3. SELECTION OF LOCATIONSelect a location for installation that meets the following conditionsand get the customer’s permission.1. There is no danger of fire due to leakage of inflammable gas.2. Select the location of the unit in such a way that neither the dis-charged air nor the sound generated by the unit disturb anyone.3. The foundation is strong enough to support the weight of the unitand the floor is flat to prevent vibration and noise generation.4. The piping length between the outdoor unit and the indoor unitmay not exceed the allowable piping length.(Refer to “6. REFRIGERANT PIPING”)5. Locations where the unit’s suction vent and outlet vent do not gen-erally face the wind.Wind blowing directly into the suction or outlet vents will interferewith the unit’s operation.If necessary, install some kind of obstruction to block the wind.6. The space around the unit is adequate for servicing and the min-imum space for air inlet and air outlet is available.(See the “Installation Space Examples” for the minimum spacerequirements.)Installation Space Examples• The installation space requirement shown in figure 2 is a refer-ence for cooling operation when the outdoor temperature is 35°C.If the design outdoor temperature exceeds 35°C or the heat loadexceeds maximum capacity in all the outdoor unit, take an evenlarge space on the intake shown in figure 2.• During installation, install the units using the most appropriate ofthe patterns shown in figure 2 for the location in question, takinginto consideration human traffic and wind.• If the number of units installed is more than that shown in the pat-tern in figure 2, install the units so there are no short circuits.• As regards space in front of the unit, consider the space neededfor the local refrigerant piping when installing the units.• If the work conditions in figure 2 do not apply, contact your dealeror Daikin directly.(Refer to figure 2)1. Front side2. No limit to wall height3. Service space of front side4. Service space of suction sideFor Patterns 1 and 2 in figure 2 :• Wall height for front side – no higher than 1500 mm.• Wall height on the suction side – no higher than 500 mm.• Wall height for sides – no limit.• If the height is exceeded the above, calculate h1 and h2 shownin the figure below, and add h2/2 to the service space of frontside and h1/2 to the service space of suction side.Number of outdoor units connected 2 units 3 unitsKit name BHFP26A90 BHFP26A136to indoor unitOutdoorunit AOutdoorunit BOutdoorunit COutdoor unitmulti connectionpiping kit(first branch)Outdoor unit multiconnection piping kit(second branch)Unit capacityA ≥ B ≥ C2 pcs.ShapeLiquid sideaccessorypipe (1)Equalizer sideaccessory pipe(1)Equalizer sideaccessory pipe(2)L typeaccessoryjoint (1)L typeaccessoryjoint (2)Liquid sideaccessorypipe (2)Suction gasside accessorypipe (1)Suction gasside accessorypipe (2)HP / LP gasside accessorypipe (1)HP / LP gasside accessorypipe (2)1 pc. 1 pc. about each itemClamp(1)(Large)1 pc.1 pc.1 pc.8 pcs.Clamp(2)pc.1(Small)8 · 10 type14 · 16 typeQuantityQuantityClamp(3)ShapeNameNameNamepcs.212 type8 · 10 type14 · 16 type12 type pc.1Manuals, etc.ShapeQuantity• Operation manual• Installation manual• Declaration of conformity (PED)• "REQUEST FOR THE INDICATON"label (Installation records)• "ADDITIONAL REF.
