Drain test

The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation:

Feed water Flexible drain hose Main drain pipe Drain port Glue the joint Drain pump Drain pan Drain hose connection Use the clip

• Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end.
• Feed water to the flexible drain hose and check the piping for leakage.
• Be sure to check the drain pump for normal operating and noise when electrical wiring is complete.
• When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.

CAUTION:

After the confirmation of the above conditions, prepare the wiring as follows:

1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screws which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
- Vibration of a magnetic switch, damage on the contact point, fuse breaking, disturbance by the normal function of an overload protection device.
- Proper starting power is not given to the compressor.

Airborne Noise Emission

The A-weighted sound pressure emitted by this product is below 70 dB.

** The noise level can vary depending on the site.

The figures quoted are emission level and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e. the number of equipment and other adjacent processes and the length of time for which an operator exposed to the noise. Also, the permissible exposure level can vary from country to country. This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk.

Limiting concentration

Limiting concentration is the limit of Freon gas concentration where immediate measures can be taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall be described in the unit of kg/m ^3 (Freon gas weight per unit air volume) for facilitating calculation

Limiting concentration: 0.44kg/m ^3 (R410A)

■ Calculate refrigerant concentration

Refrigerant concentration = amount of replenished refrigerant in refrigerant facility (kg)Capacity of smallest room where indoor unit is installed (m^3)

Oqava quvurlari

• Oqava quvurlari pastga qiya bo'lishi kerak (1/50 to 1/100): orqaga oqib kirmasligi uchun pastga-tepaga qiyalanmasin.
• Oqava quvurlarini ulashda ichki blokning oqava portiga ortiqcha kuch ishlatmang.
• Ichki blokdagi oqava ulanishining tashqi diametri 32mm.

Quvur materiali: Polivinil xlorid (PVX) VP-25 quvuri va quvur moslamalari.

- Drenaj quvur yo'li termoizolyator bilan o'ralganligiga ishonch hosil qiling.

Sizib chiqishni tekshirish

Havo konditsioneri oqava nasosi yordamida suvni chiqarib yuboradi.

Oqava nasosining ishlashini sinab ko'rish uchun quyidagilarni bajaring:

Suv yuboring Oqava nasosi Oqava tagligi Asosiy oqava guvurini tashqi tomonga Egiluvchan oqava shlangi Asosiy oqava quvuri Ulamani Ekitir simlariny valabang Oqava shlangi ulanishi Qisqich ishlating Oqava ulang va sinov tugagunicha joyida qoldiring. Egiluvchan oqava shlangiga suv yuboring va quvurlardan suv sizib chiqishini tekshiring. Oqava nasosi normal ishlayotgani va ovoz chiqarayotganini tekshirib ko'ring. Sinov tugallangach, egiluvchan oqava shlangini ichki blokdagi oqava portiga ulang.
