Safety Precautions WARNING Have the unit professionally installed. Be sure to carefully follow each step in this handbook when Improper installation by an unqualified person may result installing the unit. in water leak, electric shock, or fire. Improper installation may result in water leak, electric shock, smoke or fire.
Safety Precautions Precautions for Handling Units for Use with R410A Caution Do not use the existing refrigerant piping Use a vacuum pump with a reverse-flow check valve. If other types of valves are used, the vacuum pump oil will The old refrigerant and refrigerator oil in the existing piping flow back into the refrigerant cycle and cause the refrigerator contain a large amount of chlorine, which will cause the refrigerator oil in the new unit to deteriorate.

Safety Precautions Before Installing (Relocating) the Unit or Performing Electric Work Caution Ground the unit. Do not spray water on the air conditioners or immerse the Do not connect the grounding on the unit to gas pipes,water air conditioners in water. pipes, lightning rods, or the grounding terminals of Water on the unit presents a risk of electric shock.
Read Before Installation Items to Be Checked (1). Verify the type of refrigerant used by the unit to be serviced. Refrigerant Type: R410A (2). Check the symptom exhibited by the unit to be serviced. Look in this service handbook for symptoms relating to the refrigerant cycle.

Read Before Installation Piping Materials Types of Copper Pipes (Reference) Maximum Operation Pressure Applicable Refrigerants 3.4MPa R22, R407C 4.15MPa R410A Use pipes that meet the local standards. Piping Materials/Radial Thickness Use pipes made of phosphorus deoxidized copper. Since the operation pressure of the units that use R410A is higher than that of the units for use with R22, use pipes with at least the radial thickness specified in the chart below.

Read Before Installation Air Tightness Test No changes from the conventional method. Note that a refrigerant leakage detector for R22 or R407C cannot detect R410A leakage. Halide torch R22 or R407C leakage detector Items to be strictly observed : Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment's air tightness, taking temperature variations into account.
Installation Procedure Installation of Outdoor Unit 1. Selection of the place of installation Select the place of installation satisfying the following conditions and, at the same time, obtain a consent from the client or user. Place where air circulates. Place free from heat radiation from other heat sources. Place where drain water may be discharged.

Installation Procedure Piping Connection 1. Piping diagram YUD060A 3-way stop valve Flare connection Gas pipe Indoor Outdoor unit unit Liquid pipe 3-way stop valve 2. Piping size 90+0.5 Liquid pipe 9.52x0.8mm YUDA060 Install the removed flare nuts to the pipes to be connected, then flare the pipes.
Installation Procedure Air Tightness Test After finishing connection of refrigerant pipe, it shall perform air tightness test. The air tightness test adopts nitrogen tank to give pressure according to the pipe connection mode as the following figure shown. The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas and liquid valve rods).

Installation Procedure Vacuuming Piping vavuum method: to use vacuum pump Liquid stop valve Gas stop valve Detach the service port's cap of gas stop valve, the valve rod's cap for liquid stop valve and gas stop valve, and connect the service port into the projection Gauge manifold(R410A) of charge hose (low) for gaugemanifold.
Installation Procedure Electrical Wiring WARNING! DANGER OF BODILY INJURY OR DEATH TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC CONNECTIONS. GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS. Precautions for Electrical wiring Electrical wiring work should be conducted only by authorized personnel.
Installation Procedure Electrical Wiring Wiring procedure 1) Remove set screws on the side before taking off the front panel toward the direction. 2) Connect wires to the terminal block correctly and fix the wires with a wire clamp equipped nearby the terminal block. 3) Route the wires in a proper way and penetrate the wires through the opening for electrical wiring on the side panel.
