This document is an installation manual for a Senville Split Type Wall-mounted Inverter Room Air Conditioner.
Function Description:
The device is a split-type, wall-mounted inverter room air conditioner designed for residential or commercial use. It provides cooling and heating functionalities to maintain desired room temperatures. The inverter technology allows for more efficient operation by adjusting the compressor speed to match the cooling or heating demand, rather than cycling on and off. The "split-type" designation means it consists of two main units: an indoor unit that circulates conditioned air within the room and an outdoor unit that houses the compressor and condenser, exchanging heat with the outside environment. The manual emphasizes proper installation to ensure safety, optimal efficiency, and longevity of the unit.

- Means for disconnection from a power supply with an air gap contact separation of at least 3mm in each active (phase) conductor must be incorporated.
Refrigerant Pipe Connection:
- Flaring Work: Detailed instructions for cutting pipes, burr removal, and flaring dimensions (A-values for different outer diameters) are provided to ensure proper sealing and prevent leaks.
- Outer diam. (mm) | A (mm) Max. | A (mm) Min.
- Φ 6.35 | 1.3 | 0.7
- Φ 9.52 | 1.6 | 1.0
- Φ 12.7 | 1.8 | 1.0
- Φ 16 | 2.4 | 2.2
- Tightening Torque: Specific tightening torques for flare nuts are given to prevent overtightening and breakage.
- Outer diam. (mm) | Tightening torque (N.cm) | Additional tightening torque (N.cm)
- Φ 6.35 | 1500 (153kgf.cm) | 1600 (163kgf.cm)
- Φ 9.52 | 2500 (255kgf.cm) | 2600 (265kgf.cm)
- Φ 12.7 | 3500 (357kgf.cm) | 3600 (367kgf.cm)
- Φ 16 | 4500 (459kgf.cm) | 4700 (479kgf.cm)
- Refrigerant Types and Additional Charge:
- R22: (Pipe length-5)x30g/m for liquid side Φ6.35, (Pipe length-5)x60g/m for liquid side Φ9.53.
- R410A: (Pipe length-5)x20g/m for liquid side Φ6.35, (Pipe length-5)x40g/m for liquid side Φ9.53.
Usage Features:
- Remote Control: The unit is operated via a remote controller.
- Mode Selection: Users can select COOL, HEAT, AUTO, and FAN modes.
- Manual Operation: A manual control button is available for AUTO or COOL mode, primarily for situations where the remote controller is disabled or for maintenance. This is particularly useful when ambient temperatures are too low (below 17°C) for the remote to initiate cooling mode.
Maintenance Features:
- Safety Checks: The manual outlines crucial safety checks to be performed after installation, including:
- Grounding Work: Visual detection and grounding resistance testing (resistance less than 4 Ω).
- Electrical Leakage Check: Performed during test operation using an electroprobe and multimeter.
- Gas Leak Check: Using soap water (checking for bubbles) or a leak detector on connection points.
- Air Purging: Emphasizes the importance of removing air and moisture from the refrigerant system using a vacuum pump to prevent issues like pressure rise, current rise, efficiency drop, freezing of capillary tubing, and corrosion.
- Test Running: A 30-minute test run is recommended after installation to confirm all functions work correctly across different modes.
- Accessibility: The indoor unit panel can be lifted for access to the electrical box for wiring connections.
General Safety and Installation Precautions:
- Installation must be performed by a licensed electrician or specialist.
- Use only attached accessories and specified parts.
- Install on a strong, firm location capable of withstanding the unit's weight.
- Follow local and national wiring standards and regulations.
- Ensure proper drainage to prevent water leakage into the room.
- Do not install near flammable gas sources.
- Avoid installing in places with high-frequency machines, welding equipment, or medical facilities.
- Ensure proper insulation of copper lines.
- Avoid modifying the power supply cord or using extension cords.
- Do not share a single outlet with other electrical appliances.
- Properly arrange wiring to prevent heat-up or electrical shock.
- Ensure no air substances other than the specified refrigerant enter the refrigeration cycle.
- The outdoor unit should be anchored tightly and horizontally on a concrete or rigid mount.
- Consider noise and vibration when selecting an installation place.
- Protect the outdoor unit from direct sunlight and strong winds.
