NOTES
1 Leave space for servicing the unit and include inspection hatch. (Always open a
hole on the side of the control box so that the air filters, heat exchange elements,
fans, and humidifier elements can easily be inspected and serviced.)
2 Install the two outdoor ducts with down slope (slope of 1/30 or more) to prevent

entry of rain water, also, provide insulation for three ducts (outdoor ducts and

indoor supply air duct) to prevent dew condensation) (material: glass wool of
25mm thick).
3 Do not turn the unit upside down.

supply shut-off valve, and a drain valve (both locally procured) somewhere along
the water supply piping that can be reached from the inspection.
5 It is impossible to connect the water supply piping directly to public piping, use
a cistern tank (of the approved type), if you need to get your water supply from
public piping.

(Locally procured) 6 Make sure the supply water 0.02MPa to 0.49MPa (0.2kg/cm² to 5kg/cm²)
7 Make sure the supply water is between 5°C and 40°C in temperature.
8 Insulate the water supply piping to prevent condensation from forming.
9 Make sure install drain piping, and insulate drain piping to prevent dew
condensation.
10 Keep the drain pipe short and sloping downwards at a gradient of at least 1/100
to prevent air from forming.
11 Install in a location where the air around the unit or taken into the humidifier will
not drop below 0°C.
12 Do not use a bent cap or a round hood as the outdoor hood if they might get
rained on directly (we recommend using a deep hood) (optional accessory).
13 In areas where freezing may occur, always take steps to prevent the pipes from
freezing.
14 Do not place something which shouldn't be get wet at the below of this unit. The
dew would fall at following case, where humidity is 80% more, or the exit of drain
socket is choked up, or the air filter is very dirty.
15 Feed clean water, the supply water is hard water. Use water softener because

of short life. Life of humidifying element is about 3 years 4,000 hours), under the
supply water conditions of hardness: 150mg/L. (Life of humidifying element is
about 1 year (1500 hours), under the supply water conditions of hardness:
400mg/L.)
