11.2.1 Select the Best Location
If an awning is built over the unit to prevent direct
sunlight or rain, be careful that heat radiation from
the condenser is not obstructed.
There should not be any animal or plant which
could be affected by hot air discharged.
Keep the spaces indicated by arrows from wall,
ceiling, fence or other obstacles.
Do not place any obstacles which may cause a
short circuit of the discharged air.
If piping length is over the [piping length for
additional gas], additional refrigerant should be
added as shown in the table.
Example: For E12***
If the unit is installed at 32.8 ft (10 m) distance, the
quantity of additional refrigerant should be 1.64 oz
(50 g) .... (32.8 - 24.6) ft x 0.2 oz/ft = 1.64 oz.
((10 - 7.5) m x 20 g/m = 50 g).
