When installing insulation in places and conditions below, use the same insulation that is used for high humidity conditions.
<Geological condition>
- High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building is covered by
earth and sand.)
<Operation purpose condition>
- Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
- The ceiling frequently exposed to moisture and cooling is not covered.
e.g. The pipe installed at a corridor of a dormitory and studio or near an exit that opens and closes frequently.
- The place where the pipe is installed is highly humid due to the lack of ventilation system.
Drainpipe and drain hose installation
Care must be taken when installing the drain hose for the indoor unit to ensure that any conden-
sate water is correctly drained outside.
The drain hose can be installed to the right of the base pan.
1.
Installing the drain hose should be the shorter, the better.
In order to discharge condensation water, the drain hose should keep tilted.
Fix the drain hose with Cable-Tie, so that it will not separate from the machine.
While using draining pump, connect the end with draining pump.
2.
Insulate and fix the drain hose according to the figure.
Insert the drain hose to bottom of the outfall of water basin.
Lock steel ring of the drain hose according to the figure.
Wind and wrap steel ring and drain hose fully with thermal insulation sponge; fix both ends of
external layer with ribbon for thermal insulation.
After being installed, drain hose must be insulated fully by heat insulating material. (To be pro-
vided at site.)
