ENGLISH
The foundation must be level even.
Outdoor unit foundation work
Avoid short circuits and ensure
sufficient space is allowed for service.
Installation of outdoor unit
Refer to automatic addressing flowchart.
Automatic addressing of indoor unit
In the final check for 24 hours at 3.8 MPa(38.7 kgf/cm
2
) there
must be no drop in pressure.
Airtight test
Multiple core cable must not be used.
(suitable cable should be selected)
Electrical work
(connection circuits and drive circuits)
Make sure no gaps are left where
the insulating materials are joined.
Heat insulation work
Make sure airflow is sufficient.
Duct work
Adjust to downward gradient.
Drain pipe work
Special attention to dryness,
cleanness and tightness.
Refrigerant piping work
Check model name to
make sure the fitting
is made correctly.
Installation of indoor unit
Take account of gradient
of drain piping.
Sleeve and insert work
Make connection clearly between outdoor, indoor,
remote controller and option.
Preparation of contract drawings
Indicate clearly who will be responsible for switch setting.
Determination of division work
The vacuum pump used must have a capacity of reaching at least
5 torr, more than 1 hour.
Vacuum drying
Recharge correctly as calculated in this manual. and record the
amount of added refrigerant.
Additional charge of refrigerant
Make sure there are no gaps left between the facing materials
used on the ceiling.
Fit facing panels
Run each indoor unit in turn to make sure the pipe work
has been fitted correctly.
Test run adjustment
Explain the use of the system as clearly as possible to your customer and
make sure all relevant documentation is in order.
Transfer to customer with explanation
Preheat the crank case with the electrical heater for more than 6 hours.
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 3.8 MPa.
• Since R410A is a mixed refrigerant, the required additional
refrigerant 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.)
!
• Ratio of the connectable Indoor Units to the Outdoor: Within 50 ~ 160 %
• Ratio of running Indoor Units to the Outdoor: Within 10 ~ 100 %
• A combination operation over 100 % cause to reduce each indoor unit capacity.
