This document serves as both an operation and installation manual for Haier Duct Type Air Conditioners, covering models AD100S2SH5FA, AD125S2SH5FA, AD140S2SH5FA, AD160S2SH5FA, AD180S2SH5FA, and ADH200H1ERG. It emphasizes safety, proper installation, and maintenance to ensure optimal performance and longevity of the unit.
Function Description
The Haier Duct Type Air Conditioner is designed for cooling and heating indoor spaces. It operates by circulating air through ducts, providing a discreet and efficient climate control solution. The system utilizes a heat pump for warming, concentrating heat from outdoor air with the help of refrigerant to warm the indoor space.
Key operational features include:
- "HOT KEEP" Function: This function prevents the blowing of cool wind when heating starts, stopping the indoor unit fan until the room temperature reaches a suitable level. It also manages defrosting operations, automatically pausing heating for 5-12 minutes every hour to remove frost from the outdoor unit's heat exchanger, then resuming normal heating. When the room thermostat actuates due to rising room temperature, the fan speed automatically adjusts to stop under low temperature conditions of the indoor heat exchanger.
- Warming Operation: Employs a heat pump mechanism to efficiently warm indoor spaces.
- Defrosting Operation: Automatically switches to defrosting mode when frost accumulates on the outdoor unit's heat exchanger during heating, interrupting heating for a short period to maintain efficiency.
- Automatic Restart After Power Failure: If the unit is operating during a power failure, it will automatically restart in the same mode once power is restored.
Important Technical Specifications
The manual provides crucial technical specifications for proper installation and operation:
- Applicable Ambient Temperature Range:
- Cooling: Indoor temperature (DB/WB) max. 32/23°C, min. 18/14°C. Outdoor temperature (DB/WB) max. 43/24°C, min. 10/6°C.
- Heating: Indoor temperature (DB/WB) max. 27°C, min. 15°C. Outdoor temperature (DB/WB) max. 24/18°C, min. -15°C.
- Air conditioner working temperature: cooling 10~43 degrees, heating -15~24 degrees.
- Refrigerant Type: R410A (GWP: 2088) or R32 (GWP: 675). The product contains fluorinated greenhouse gases covered by the Kyoto Protocol.
- Power Supply and Wiring:
- The supply cord, if damaged, must be replaced by the manufacturer or a qualified service agent.
- Fuse type on indoor PCB: T8A/250V for all listed models.
- Wiring method must comply with local wiring standards.
- Power Cable: H05RN-F 3G 4.0mm² (for outdoor unit 1U71S2SS5FA/1U100S2SN5FA), H05RN-F 3G 6.0mm² (for outdoor unit 1U125/140/160/180S2SP5FA), or H05RN-F 5G 4.0mm² (for outdoor unit 1UH200W1ERK).
- Connecting Cable: H05RN-F4G 2.5mm².
- All cables must have European authentication. Grounding wire must be the last to break off during installation.
- Power and connect cables are self-provided.
- Breaker: All-pole switch with a minimum 3mm distance between contacts.
- A leakage breaker must be installed.
- Indoor Unit Installation Height: At least 2.5m.
- External Static Pressure: The manual provides a table with 10 levels of static pressure (Pa) for different models, with level 2 being the factory default. These settings can be adjusted via a wired controller or zone controller.
- Pipe Sizes:
- AD100-160S2SH5FA: Liquid side Ø9.52mm, Gas side Ø15.88mm.
- AD180S2SH5FA/ADH200H1ERG: Liquid side Ø12.7mm, Gas side Ø19.05mm.
- Drain Pipe: The position of the installed drain pipe should have a downward gradient of 1/100 or more. For units without a water pump, the drain pipe length should be less than 20m, with supports every 1.5-2m for long pipes. For units with a water pump, hard PVC general purpose pipe (VP) should be used.
- Minimum Room Area for R32 Refrigerant: A table specifies minimum room areas based on refrigerant charge (kg) and height (m) to prevent out-of-limit refrigerant concentration in case of leakage.
Usage Features
- User-Friendly Controls: The system is designed to be operated via a wired controller, with instructions provided in a separate manual.
- Quiet Operation: The A-weighted sound pressure level is below 70 dB.
- Ventilation: Regular ventilation of the room is recommended when using the unit for long periods.
- Optimal Operation Guidelines:
- Adjust room temperature for comfort, avoiding excessive heating or cooling.
- Prevent direct sunlight during cooling by using curtains or blinds.
- Keep doors and windows closed to maintain efficiency.
- Avoid placing objects near air inlets/outlets to prevent performance reduction.
- Turn off the main power supply switch when not in use for long periods to save energy.
Maintenance Features
The manual outlines essential care and maintenance procedures to ensure the unit's efficiency and longevity:
- Cleaning the Air Filter:
- Clean by lightly tapping or using a cleaner.
- For very dirty filters, dissolve neutral detergent in lukewarm water (approx. 30°C), rinse thoroughly, and dry before reinstallation.
- Caution: Do not dry the air filter with fire. Do not run the air conditioner without the air filter.
- Care and Cleaning of the Unit:
- Clean with a soft, dry cloth.
- For very dirty surfaces, use neutral detergent in lukewarm water, wipe with a wet cloth, and then clean off the detergent with clean water.
- Post-Season Care:
- Operate the unit in FAN mode for half a day on a fair day to dry the inside.
- Stop operation, turn off the power supply switch, and clean the air filter before storing.
- Pre-Season Care:
- Ensure no obstacles block air inlets and outlets of indoor and outdoor units.
- Make sure the air filter is clean.
- Turn on the power supply switch 12 hours before starting operation.
- Professional Inspection and Maintenance:
- The capacity of the air conditioner may decrease due to internal contamination after about three years of use.
- Special inspection/maintenance services are recommended beyond usual maintenance.
- It is advisable to make a maintenance contract with a qualified dealer.
Safety Precautions
The manual places a strong emphasis on safety, categorizing precautions into "WARNING" and "CAUTION" to highlight potential risks:
- Installation: Must be performed by qualified personnel or a professional installer. Improper installation can lead to water leakage, electric shocks, or fire.
- Refrigerant Leakage: In unventilated rooms, measures must be taken to ensure allowable refrigerant concentration is not exceeded, as leakage can cause oxygen deficiency.
- Electrical Safety: All electrical repairs must be carried out by qualified electricians. The unit must be properly grounded. Always unplug the unit before opening the inlet grill.
- Unit Integrity: Do not damage refrigerant-carrying parts. Do not obstruct ventilation grilles or insert objects into openings.
- Environmental Considerations: Do not install near flammable gas sources. Avoid placing burners or heaters directly in the airstream.
- Disposal: The product contains electrical and electronic components and refrigerants that require specialized waste disposal. Do not dismantle the system yourself; contact a qualified installer or local authority. Batteries from the remote controller must be disposed of separately.
- Children's Safety: Children should be supervised to ensure they do not play with the appliance. The appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities unless supervised.
