INSTALLATION GUIDE AT THE SEASIDE
INSTALLATION PROCESS
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
Automatic addressing of indoor unit
Airtight test
Heat insulation work
Make sure airflow is sufficient Duct work
Adjust to downward gradient
Drain pipe work
Refrigerant piping work
Installation of indoor unit
Sleeve and insert work
Preparation of contract drawings
Indicate clearly who is to be responsible for switch settings
Determination of division work
Vacuum drying
Additional charge of refrigerant
Fit facing panels
Test run adjustment
Transfer to customer with explanation
Make relationship between outdoor, indoor, remote controller, and
option connections clear. (Prepare control circuit diagram)
Take account of
gradient
of drain piping
Check model name to
make sure the fitting
is made correctly
Special attention to dryness,
cleanness and tightness
Multiple core cable must not be used.
(suitable cable should be selected)
In the final check for 24hours at 3.8 MPa(38.7 kgf/cm
2
) there must
be no drop in pressure.
The vacuum pump used must have a capacity of reaching at least 5
torr, more than 1 hour
Recharge correctly as calculated in this manual. and record the
amount of added refrigerant
Make sure there are no gaps left between the facing materials used
on the ceiling
Refer to automatic addressing flowchart
Preheat the crank case with the electrical heater for more than 6
hours. (In case of outdoor temperature below 10°C
(
Run each indoor unit in turn to make sure the pipe work has been
fitted correctly
Explain the use of the system as clearly as possible to your customer
and make sure all relevant documentation is in order
Make sure no gaps are left where
the insulating materials are joined
Electrical work
(connection circuits
and drive circuits)
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
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.)
