Drain Piping

Drain piping must have down slope 1/50 to 1/100 be sure not to provide up-and-down slope to prevent reversal flow. During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. The outside diameter of the drain connection on the indoor unit is 32 mm.

Piping material

Polyvinyl chloride pipe VP-25 and pipe fittings. Be sure to install heat insulation on the drain piping. Heat insulation material: Polyethylene foam with thickness more than 8 mm.

Drain test

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

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
The supplied flexible drain hose should not be curved, neither screwed. The curved or screwed hose may cause a leakage of water.

Attention

1. Possible drain-head height is up to 700 mm. So, it must be installed below 700 mm.
2. Keep the drain hose downward up to 1/50~1/100 inclination.
3. Prevent any upward flow or reverse flow in any part.

3. 5 mm or thicker formed thermal insulator is provided for the drain pipe Upward routing is not allowed. Be sure to check the drain pump for normal operation and abnormal noise when electrical wiring is complete.

Model Designation

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/m3 Freon gas weight per unit air volume for facilitating calculation. Limiting concentration: 0.44 kg/m3 (R410A)
