Function Description

The YORK Floor Ceiling R410A 50Hz air conditioner is designed for cooling, dehumidifying, and ventilation in ordinary dwellings. It operates using refrigerants that require specialized waste disposal. The unit features an indoor and outdoor component, with the indoor unit having an operating control panel, emergency switch, various indicator lamps (Power, Operation, Timer, Compressor), and a remote receiver. The outdoor unit includes a compressor and air inlet/outlet.

Important Technical Specifications

Refrigerant Circuit: The refrigerating circuit is leak-proof. Power Supply Disconnection: For all models, an all-pole disconnection method must be applied in the power supply, incorporated into the fixed wiring. The breaker should be an all-pole switch with a contact distance of no less than 3 mm. Wiring: Only copper wire with a local authentication certificate should be used. Power supply connects from the outdoor side, with connecting and power cables being self-provided. Temperature and Humidity Range (Cooling):

Indoor Temperature: Max DB/WB 32/23 °C, Min DB/WB 18/14 °C
Outdoor Temperature: Max DB/WB 43/26 °C, Min DB/WB 18/- °C Fuse: If the fuse on the PC board is broken, it should be replaced with a type T3.15A/250VAC. Connection Pipe Requirement (Diameter and Length):
YIFFYC025BAEFA: Liquid side Ø9.52 mm, Gas side Ø15.88mm; Max length 30 m, Max height 10m.
YIFFYC030BAEFA, YIFFYC036BAEFA, YIFFYC036BANFA: Liquid side Ø9.52 mm, Gas side Ø19.05mm; Max length 30 m, Max height 10m (for 030) / 15m (for 036).
YIFFYC040BAEFB, YIFFYC040BANFA: Liquid side Ø9.52 mm, Gas side Ø19.05mm; Max length 50 m, Max height 20m. Refrigerant Charging: For connecting pipes less than 7.5m, no additional refrigerant is needed. If exceeding 7.5m, charge (L-7.5) x 50 (g) of additional refrigerant per meter, only in COOLING operation and in liquid condition. Fastening Torque for Pipes:
Liquid pipe 6.35mm: 14.2-17.2N·m
Liquid pipe 9.52mm: 32.7-39.9N·m
Gas pipe 12.7mm: 49.5-60.3N·m
Gas pipe 15.88mm: 61.8-75.4N·m
Gas pipe 19.05mm: 97.2-118.6N·m Power Supply and Interconnecting Wires (20m length, <2% voltage drop):
YIFFYC025BAEFA: 1PH, Switch breaker 30A, Overcurrent protector 18A, Wire size 4.0mm², Earth leakage breaker 30A/30mA.
YIFFYC030BAEFA, YIFFYC036BAEFA, YIFFYC040BAEFB: 1PH, Switch breaker 40A, Overcurrent protector 20A/24A/28A, Wire size 5.3mm², Earth leakage breaker 40A/30mA.
YIFFYC036BANFA, YIFFYC040BANFA: 3PH, Switch breaker 30A, Overcurrent protector 8A/10A, Wire size 2.5mm², Earth leakage breaker 30A/30mA.

Usage Features

Operation Control Panel: The indoor unit features an operating control panel with indicator lamps for Power, Operation, Timer, and Compressor status.
Emergency Switch: An emergency switch is provided for immediate control.
Remote Receiver: The unit can be controlled via a remote receiver. For wired control units, the wired controller is used instead.
Automatic Restart: The unit has an automatic restart system that activates after power stoppage.
Swing Motor Test: When the indoor unit is turned on, the PCB tests the swing motor, and then the fan motor starts up after a few seconds.
Anti-condensation: In cooling mode, the flaps automatically swing to a fixed position to prevent condensation.
3-Minute Delay Protection: After stopping, the unit will not resume cooling, dry, or heating operation for 3 minutes due to a built-in delay protection circuit.
Dry Mode Fan Speed: In dry mode, the unit will repeatedly and automatically reduce fan speed if the room temperature is too low.
Indoor Fan Operation (Heating): In heating operation, the indoor fan continues running until the indoor unit cools down after the unit is stopped.

Maintenance Features

Air Filter Cleaning: Filters can be easily removed from the intake grill, cleaned with a vacuum cleaner or by washing, and then re-attached.
Regular Inspection: For extended use, regular inspection by authorized service personnel is recommended due to potential dirt accumulation inside the unit.
Cleaning Precautions: When cleaning the unit's body, avoid water hotter than 40°C, harsh abrasive cleansers, volatile agents (benzene, thinner), liquid insecticides, or hairsprays.
Drying Internal Parts: If the unit is shut down for a month or more, operate it in Fan mode continuously for about half a day to thoroughly dry internal parts.
Base Check: After long-term use, the unit's base should be checked for damage to prevent accidents.
Troubleshooting Guide: The manual includes a comprehensive troubleshooting guide for common issues like the unit not starting, poor cooling/heating, and various error codes indicated by LED flashes on the receiver board.
Error Code Diagnosis: Detailed tables are provided for diagnosing issues based on LED flash times, identifying malfunctions such as sensor errors, compressor overcurrent, communication problems, and drain system malfunctions.
Test Run Procedure: A test run procedure is outlined for both indoor and outdoor units, including checks for remote control function, lamp indicators, louvers, drain, abnormal noise/vibration, and gas leakage. For heat pump models, it's crucial to energize the crankcase heater for over 12 hours before the test run.
