WARNING
• Water condensation on the floor
While cooling operation, it is very important to keep leaving water temperature higher than 16
dewcondensation can be occurred on the floor.If floor is in humid environment, do not set leaving water
temperature below 18 °C.
• Water condensation on the radiator
While cooling operation, cold water may not flow to the radiator. If cold water enters to the radiator, dew
generation on the surface of the radiator can be occurred.
• Drainage treatment
While cooling operation, condensed dew can drop down to the bottom of the unit. In this case, prepare
drainagetreatment (for example, vessel to contain condensed dew) to avoid water drop.
• Shutoff Valve
• While assembling two shut-off valves, that are found inside 'AWHP Installation Kit', pop sound will be
heard when valve is open or close by rotating handles. It is normal condition because the sound is due
to leakage of charged nitrogen gas inside the valve. The nitrogen gas is applied to secure quality
assurance.
• Before starting water charging, these two shut-off valves should be assembled with water inlet and outlet pipe
of the indoor unit.
