Select a well-ventilated, stable site, away from flammable gas or product leaks, with adequate servicing space.
Do not install where mineral oil, salt, sulphurous gas, voltage fluctuations, or electromagnetic waves are present.
Prepare a water drainage channel around the foundation to manage waste water from the unit.
Elevate foundations and clear rear grilles to prevent snow accumulation when installing in snowy areas.
Install a waterproof plate within 150mm of the unit's underside on a frame to prevent water damage.
Check installation ground strength and levelness to prevent operating vibration or noise.
Remove crate, fixings, and place the unit on a solid foundation, securing with foundation bolts.
Securely fix the unit using foundation bolts, ensuring their length is 20mm from the foundation surface.
Refer to figure 1 for required dimensions for installation servicing space.
Details pipe sizes for gas and liquid lines for pair and simultaneous operation systems.
Provides maximum allowable piping lengths and height differences between units.
The minimum piping length must be 7.5m to prevent overcharging and system issues.
Explains oil return issues when the outdoor unit is below the indoor unit and how to mitigate them.
Install oil traps in the gas pipe every 15m if the level difference exceeds 15m.
Use dedicated tools for R407C, charge in liquid state, and use vacuum pumps suitable for the pressure.
Describes connection methods and provides details on flange, flare nut, and brazing.
Cover stop valves with sealing material to prevent condensed water from moving to the indoor unit.
Provides dimensions for flare processing and required tightening torques to prevent damage.
Coat flares with refrigerant oil (ether or ester for R407C) before tightening.
Flow nitrogen gas through the pipe during brazing to prevent contamination.
Prevent foreign materials, moisture, and impurities from entering the system during installation.
Describes how to open the stop valve by turning the shaft counterclockwise and tightening the cap.
Details how to close the stop valve by turning the shaft clockwise and tightening the cap.
Provides specific tightening torques for service ports and valve caps for different unit models.
Perform air tight test with nitrogen and vacuum drying to remove moisture, aiming for -100.7kPa.
Conduct leak test using soap water or other methods after evacuating and pressurizing with nitrogen.
Charge refrigerant based on pipe length, using specific formulas for R407C and R22 systems.
Charge R407C in liquid state to maintain its composition and ensure normal operation.
Total charging amount is the sum of nameplate value and additional charge required for pipe length.
Steps to perform pumping-down operation to protect the compressor using the low-pressure switch.
Never short-circuit the low-pressure switch; use insulation sheets for protection against electric shock.
All wiring must be done by an authorized electrician, complying with local codes and using dedicated circuits.
Connect power supply cables in normal phase; reverse phase causes 'U1' error. Switch L1, L2, L3 if needed.
Follow the electric wiring diagram for electrical wiring works and ensure proper grounding resistance.
Refer to the indoor unit installation manual for wiring of indoor units, etc.
Attach an earth leak detector and fuse to the power supply line.
Details required wire types, sizes, and compliance with local codes for power supply and unit connections.
Refer to the indoor unit installation manual for the test run procedure.
Dismantling and treatment of unit parts must comply with relevant local and national regulations.
Explanation of symbols used in the wiring diagram, including field wiring, terminals, and wire clamps.
List of components identified by codes, such as L1, L2, A1P, BS1, K1M, M1C, R3T, etc.
List of components specific to R407C systems, such as A3P, DS2, DS3, HAP, R3T, RyCH, etc.
