Note4.If piping is installed in front of the unit, provide clearances
as shown in Fig.
A
and Fig. B.
Note5.Environmental condition for installation; -20~40°C(DB)
(-4~104°F) for indoor installation.
Note6.In case the temperature around the heat source unit has
possibility to drop under 0°C(32°F), be careful for the following point to prevent the pipe burst by the water pipe freeze-up
.
•Circulate the water all the time even if heat source unit is not in operation and provide glycol for freeze protection. •Drain the water from inside of the heat source unit whe
n
the heat source unit will not operate for a long term
.
Note7.Ensure that the drain piping is downward with a pitch of
more than 1/100.
