Foreseemore space in the following cases:▪ When the suction side temperature regularly exceeds this temperature.▪ When the heat load of the outdoor units is expected to regularly exceed the maximum operating capacity.Discharge side Take refrigerant piping work into account when positioning the units. If your layout does not match with any of thelayouts below, contact your dealer.Single unit ( ) | Single row of units ( )See figure 1 on the inside of the front cover.A,B,C,D Obstacles (walls/baffle plates)E Obstacle (roof)a,b,c,d,e Minimum service space between the unit and obstacles A, B, C, D and EeB Maximum distance between the unit and the edge of obstacle E, in the direction of obstacle BeD Maximum distance between the unit and the edge of obstacle E, in the direction of obstacle DHU Height of the unitHB,HD Height of obstacles B and D1 Seal the bottom of the installation frame to prevent discharged air from flowing back to the suction side through the bottom of the unit.2 Maximum two units can be installed.Not allowedMultiple rows of units ( )See figure 2 on the inside of the front cover.Stacked units (max. 2 levels) ( )See figure 3 on the inside of the front cover.A1=>A2 (A1) If there is danger of drainage dripping and freezing between the upper and lower units…(A2) Then install a roof between the upper and lower units. Install the upper unit high enough above the lower unit to prevent ice buildup at theupper unit's bottom plate.B1=>B2 (B1) If there is no danger of drainage dripping and freezing between the upper and lower units…(B2) Then it is not required to install a roof, but seal the gap between the upper and lower units to prevent discharged air from flowing back to thesuction side through the bottom of the unit.7.2 Piping diagram: Outdoor unitR2TR4TR6TR1Tedijhgfa ccbeY1EY1SM1F-M2FM1CS1PLS1PHR5TR3Ta Field piping (liquid: Ø9.5 flare connection)b Field piping (gas: Ø15.9 flare connection)c Stop valve (with service port 5/16")d Accumulatore Filterf Heat exchangerg Internal service port 5/16"h Switch box cooling (only for RZQG_V1)i Compressor accumulatorj Check valve (only for RZQG71)M1C Motor (compressor)M1F‑M2F Motor (upper and lower fan)R1T Thermistor (air)R2T Thermistor (discharge)R3T Thermistor (suction)R4T Thermistor (heat exchanger)R5T Thermistor (heat exchanger middle)R6T Thermistor (liquid)S1PH High pressure switchS1PL Low pressure switch (only for RZQG_V1)Y1E Electronic expansion valveY1S Solenoid valve (4‑way valve)HeatingCooling
