INSTALLATION PROCESS

Indicate clearly who will be responsible for switch setting.
Determination of division work
Make connection clearly between outdoor, indoor,
Preparation of contract drawings
remote controller and option.
Take account of gradient

is made correctly
Special attention to dryness,
Refrigerant piping work
cleanness and tightness
Drain pipe work
Adjust to downward gradient
Make sure airflow is sufficient
Duct work
Make sure no gaps are left where
Heat insulation work
the insulating materials are joined
Electrical work Multiple core cable must not be used.
(connection circuits and drive circuits) (suitable cable should be selected)
In the final check for 24hours at 3.8 MPa(38.7 kgf/cm
Airtight test
must be no drop in pressure.
The vacuum pump used must have a capacity of reaching at least
Vacuum drying
5 torr, more than 1 hour
Recharge correctly as calculated in this manual. and record the
Additional charge of refrigerant
amount of added refrigerant
Make sure there are no gaps left between the facing materials
Fit facing panels
used on the ceiling
Refer to automatic addressing flowchart
Automatic addressing of indoor unit
Preheat the crank case with the electrical heater for more than 6 hours.
Run each indoor unit in turn to make sure the pipe work
Test run adjustment
has been fitted correctly
Explain the use of the system as clearly as possible to your customer and
Transfer to customer with explanation
make sure all relevant documentation is in order
! CAUTION
• The above list indicates the order in which the individual work
operations are normally carried out but this order may be varied
where local conditions warrants such change.
• The thickness of the piping should comply with the relevant
local and national regulations for the designed pressure 3.8MPa.
• Since R410A is a mixed refrigerant, the required additional re-
frigerant must be charged in its liquid state.(If the refrigerant is
charged in its gaseous state, its composition changes and the
system will not work properly.)
