SYSVRF AIR EVO HP Q&R GB Outdoor unit Mini VRF Heat Pump INSTALLATION MANUAL
CONTENTS PAGE PRECAUTIONS.........................................................................................................1 ATTACHED FITTINGS............................................................................................2 Accordingly the exclusive tools are required for the new refrigerant (R410A): For connecting pipes, use new and clean piping designed for R410A,and please care so that water or dust does not enter.
An insufficient power supply capacity or inappropriate installation may cause fire. Use the specified cables for wiring connect the terminals securely fix. To prevent external forces applied to the terminals from affecting the terminals. Be sure to provide grounding. Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables. Conform to the regulations of the local electric company when wiring the power supply. Inappropriate grounding may cause electric shock.
H Installation in the following places may result in problems. Do not install the unit in such places below. A place full of machine oil. A place full of sulphuric gas. A place where high-frequency radio waves are likely to be generated as from audio quipment, welders, and medical equipment. 3. OUTDOOR UNIT INSTALLATION 3.1 Installation place Please keep away from the following place, or malfunction of the machine may be caused: There is combustible gas leakage.
3.3 Moving and installation 4. INSTALL THE CONNECTING PIPE Since the gravity center of the unit is not at its physical center, so please be careful when lifting it with a sling. Never hold the inlet of the outdoor unit to prevent it from deforming. Check whether the height drop between the indoor unit and outdoor unit, the length of refrigerant pipe, and the number of the bends meet the following requirements: Do not touch the fan with hands or other objects.

Table 4-8 The straight distance between the contiguous branchpipes is at least 0.5m; The straight distance which the branch pipes connected to the indoor unit is at least 0.5m; Branch header must be connected with indoor units directly, the further branch connection is not allowed. 2.5 4 45%~130% 10.5 3 5 45%~130% 12 4 6 45%~130% 14 5 6 45%~130% Select the branch joint according to the total designed capacity of indoor units which it connects to.
The indoor unit below to the main pipe L3 are N3̚N6, and its total capacity is 28×3+22=106, the size of pipe L3 isΦ15.9/Φ9.5, and he branch pipe C should be SYSVRF JOINT IN 01 2P. The indoor unit below to the main pipe A are N1̚N6, and its to-tal capacity is 28×5+22=162, and the branch pipe should be SYSVRF JOINT IN 01 2P, and because the total piping length of liquid + air side is ≥90m, check Table.

Please contact local supplier for details .
Wrong connection may cause malfunction . NOTE Wiring Connection Seal the wiring connection with the insulation material , or there is risk for condensation. NOTE The air-conditioners can connect with Centralized wired controller (CWC). Before operation, please wire correctly and set system address and network address of indoor units The wire diameter and continuous length is under the condition that the voltage vibration is within 2%.
