Be sure to perform heat insulation on the drain piping.
Caution If insulation is insufficient, dew may form.
This causes water leakage.
Prevent the drain hose from floating and hanging
Caution down.
This causes water leakage. (down figure)
10.4.6. Heat insulation
Caution Be sure to perform heat insulation on the drain, liquid and gas piping. Imperfection in heat insulation work leads to water
leakage.
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over 100°C).
2. Precautions in high humidity circumstance.
This air conditioner has been tested according to the "JIS Standard Conditions with Mist" and have been confirmed that there
is no form of any faults. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than
23°C), water drops are liable to fall.
• • • • In addition to the normal heat insulation (thickness: more than 8 mm) for refrigerant piping (gas piping: thick piping) and
drain piping, add a further of 10 mm to 30 mm thickness material.
Wall seal
• • • • When the outdoor unit is installed on a higher position
than the indoor unit, install the trap so as not to instill
rain water into the wall by transmitted in piping.
• • • • Stuff the space among piping, the electric wire, and the
drain hose with "Putty" and seal the penetration wall
hole.
Make sure that rain water do not instill into the wall.
In the case of left piping
1. Remove both the internal and external plugs.
2. Use a wrench or pliers to remove the plugs.
• • • • Putting substitution of rubber plug.
Drain Test
Confirm the drain water flows smoothly after connecting the
drain piping.
• • • • Pour water to about 1.5 litres for the drain confirmation from
the air inlet part which should gradually flow into the drain
pan.
