This document is an installation manual for Daikin split system air conditioners, specifically models FTXJ35MV1BW6 and FTXJ35MV1BS6. It provides comprehensive instructions for the safe and effective installation, operation, and maintenance of these units.
The air conditioner is designed to provide cooling, heating, and drying functions for indoor spaces. It operates within specific temperature and humidity ranges:
- Cooling: Outdoor temperature 10~46°C DB, Indoor temperature 18~32°C DB, Indoor humidity ≤80%.
- Heating: Outdoor temperature -15~24°C DB, Indoor temperature 10~30°C DB.
- Drying: Outdoor temperature 10~46°C DB, Indoor temperature 18~32°C DB, Indoor humidity ≤80%.
A safety device may stop operation if the unit runs outside these ranges, and condensation/water dripping may occur during cooling if humidity is high.
Important Technical Specifications:
The unit incorporates a wireless LAN module for connectivity.
- Frequency Range: 2400 MHz~2483.5 MHz
- Radio Protocol: IEEE 802.11b/g/n
- Radio Frequency Channel: 1~13
- Output Power: 13 dBm
- Effective Radiated Power: 15 dBm (11b) / 14 dBm (11g) / 14 dBm (11n)
- Power Supply: DC 14 V / 100 mA
The refrigerant used in this unit is mildly flammable. The unit is considered combined equipment and complies with Directive 2014/53/EU for radio equipment.
Usage Features:
The manual outlines the process for setting up the unit, including:
- Mounting the indoor unit: This involves attaching the mounting plate, connecting refrigerant piping (which can be routed right-side, left-side, right-back, or left-back), and connecting the drain piping.
- Electrical installation: This section details the wiring connections for power supply, interconnection cable (2-core, 1.5 mm² minimum, 220-240 V), and earth. It emphasizes the use of a multi-pole disconnection type breaker with at least 3 mm between contact points.
- Wireless LAN: The unit includes a wireless LAN module. Users can find detailed specifications, installation instructions, setting methods, FAQ, and declaration of conformity on the Daikin Europe website. Precautions are given to avoid interference with medical equipment, auto-control equipment, and microwave ovens.
- Address setting: For installations with multiple indoor units, an address jumper (J4) on the user interface allows setting unique addresses (1 or 2) for each unit. The factory setting for the address jumper is 1.
- Test run: After installation, a test run is required to ensure proper functionality. This involves checking the lowest and highest temperature settings in both cooling and heating modes, and verifying that the system operates for at least 3 minutes after turning OFF.
Maintenance Features:
The manual provides guidance on maintenance aspects, primarily during installation:
- Refrigerant piping: Instructions for connecting and checking the refrigerant piping, including specifications for outer diameter, temper grade, and thickness of copper pipes (6.4 mm (1/4") and 9.5 mm (3/8")). It also specifies the minimum insulation thickness for refrigerant pipes to prevent condensation.
- Drainage: Instructions for connecting the drain piping to ensure proper evacuation of condensation water.
- Air filter: The manual mentions checking for water leaks after pouring approximately 1 liter of water into the drain pan, which implies the presence of a drain pan that may require cleaning or inspection.
- Deodorising filter: The unit includes a titanium apatite deodorising filter and a silver allergen removal air purifying filter. These are listed as components included with the unit, suggesting they are user-replaceable or require periodic maintenance.
- Spare SSID sticker: Users are advised to keep the spare SSID sticker in a safe place in case the front grille is replaced, as it contains important information for the wireless LAN.
Safety Precautions:
The manual stresses numerous safety warnings throughout:
- Installation must be performed by a qualified installer in compliance with applicable legislation (EN378 in Europe).
- The appliance must be stored in a well-ventilated room without continuous operating ignition sources to prevent mechanical damage.
- Always use multicore cable for power supply cables.
- Do not connect the power supply to the indoor unit. This could result in electrical shock or fire.
- Ensure proper earthing to prevent electrical shock.
- Secure electrical wiring with cable ties to prevent contact with sharp edges or piping.
- Do not use tapped wires, stranded conductor wires, extension cords, or connections that are not standard.
- The refrigerant is mildly flammable, and proper ventilation is required during installation.
- Do not push the refrigerant pipes onto the bottom frame of the front grille.
- Do not damage any surrounding parts when cutting the address jumper.
- Do not dismantle the system yourself; dismantling and treatment of the refrigerant, oil, and other parts must be done by a specialist treatment facility for reuse, recycling, and recovery.
- Ensure the sound pressure level is less than 70 dBA.
- Ensure nothing blocks the air flow and condensation water can be evacuated properly.
