The temperature of refrigerant circuit will be high, please keep the interconnection cable away from the copper tube. The power cord type designation is H05RN-For above/H07RN-F. 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.
The insulation of the metal parts of the building and the air conditioner should comply with the regulation of National Electric Standard. When installing the outdoor unit in a place that is constantly exposed to a strong wind such as the upper stairs or rooftop of a building, apply the windproof measures referring to the following examples. Install the unit so that its discharge port faces to the wall of the building. Keep a distance 3000mm or more between the unit and the wall surface.
4. 3.3 Moving and installation 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. Do not touch the fan with hands or other objects. Do not lean it more than 45°, and do not lay it sidelong. Make concrete foundation according to the sepecifications of the outdoor units.(refer to Fig.

Table 4-8 Branch header must be connected with indoor units directly, the further branch connection is not allowed. Capacity of Maximum Outdoor unit Quantity of (horsepower) Indoor unit Outdoor Unit (kW) Select branch joint 20 7 11 Select the branch joint according to the total designed capacity of indoor units which it connects to. If this capacity is more than that of the outdoor unit, then select the connection according to the outdoor unit. 22.
The indoor unit below to the main pipe L3 are N3～N6, and its total capacity is 45×3+56=191, the size of pipe L3 isΦ19.1/Φ9.5, and the branch pipe C should be FQZHN-01D. The indoor unit below to the main pipe A are N1～N6, and its total capacity is 45×5+56=281, and the branch pipe should be FQZHN-02D, and because the total piping length of liquid + air side is ≥90m, check Table.4-4, and the first branch pipe should apply FQZHN-02D, and according to the principle of maximum value, it should apply FQZHN-02D.

5. ELECTRICAL WIRING CAUTION ● ● ● ● ● ● ● Design a dedicated power supply for the indoor unit and outdoor unit. If the power supply uses a branch loop, install an electricity leakage protector and a manual switch. The power supply, electric leakage protectors, and manual switches of the indoor units that connect to the same outdoor unit must be universal. Use the same loop for the indoor unit power connect to the same outdoor unit must be universal.
Outdoor unit PQE Note: The parts in the dotted line box are optional.Contact the local distributor to purchase them if required. Use a shield cable and ground the shielding layer. Indoor unit Indoor unit PQE Indoor unit PQE Indoor unit PQE PQE Add a build-out resistor at the P/Q end of the last indoor unit only. Build-out resistor Wired Remote controller control Fig.
Wrong connection may cause malfunction . NOTE Wiring Connection The wire diameter and continuous length is under the condition that the voltage vibration is within 2%. If the continuous length is exceed showing value, choose the wire diameter follow relevant regulation. Seal the wiring connection with the insulation material , or the condensing dew will be caused. NOTE The air-conditioners can connect with Central Control Monitor (CCM).
6. TEST RUNNING Operate according to "gist for test running" on the electric control box cover. Table 7-2 For 335 unit only,335 unit adopt different PCB Table 7-2 CAUTION 0-F Test running can not start until the outdoor unit has been connected to the power for 12hr. Test running can not start until all the valves are affirmed open. Never make the forced running. (Or the protector sits back, danger will occur.) ENC1 & S9-3 123 0-F 123 S1-1 7.
TEST RUNNING 8. 6.PRECAUTIONS ON REFRIGERANT LEAKAGE Operate according to "gist for test running" on the electric control box 8.1 Important information for the used refrigerant cover. This product has the fluorinated NOTEgas, it is forbidden to release to air. Refrigerant type: R410A; Volume of GWP: 2088; GWP=Global Please cut offWarming the powerPotential supply when changing the dial switch This air conditioner(A/C) adopts inncouous and nonflammable refrigerant.
