•Make sure that total extension refrigerant piping lenght is 520 m. or less.
•If the refrigerant piping equivalent length exceeds 100 m, use pipes with diameters larger by
one rank indicated in “4-3. Refrigerant piping installation specifications“ on the previous page
for the main liquid and vapor piping. Example: ø 12.7 →ø 15.9.
•This unit uses R410A. Limit pressure of O material pipe with ø 19.1 diameter or larger is
insufficient. Be sure to use 1/2H or H material pipes with minimum thickness or thicker. For
ø 19.1 pipe only, however, as long as the thickness is 1.05 mm or greater, O materials can
be used.
•Method of refrigerant piping can be selected from line branching, header branching, and
line-header combined branching. Select the proper method according to the layout of indoor
units.
•Refrigerant piping length and the height difference between indoor units should be arranged
as short as possible.
•Re-branching after the header branching is not allowed.

ATTENTION
Never exceed the maximum allowed distance between AWS and GHP. Failure in doing so can
result in malfunctioning of the units and invalidates the warranty.
WARNING
• Always refer to AWS installation manual for maintenance clearence and position of the unit.
• Always connect the AWS to the designed outdoor unit for AWS.

1.9 Refrigerant charging
ATTENTION
•When charging the refrigerant, accurately measure the length of the piping and charge
the proper amount of refrigerant. If the amount of refrigerant is not proper, performance
will decline or a breakdown could occur.
• After completion of refrigerant charging, write down the installation record on the plate
“POINTS FOR INSTALLATION” inside the outdoor unit control box panel. Besides,
calculate the refrigerant amount for the whole system and write down the amount on the
plate. Calculation formula is shown on the plate. (Write with a permanent marker so that
the record does not disappear easily.)
1) Refrigerant charging amount.
Always check the refrigerant gas factory charge on the unit label before calculating the amount to be added.
Calculate the amount of refrigerant to be charged according to the following formula and liquid piping length
for each size of the piping.
When the GHP is connected to YOSHI AWS E1:
Charge amount (kg) = (L1 × 0.353) + (L2 × 0.250) + (L3 × 0.170) + (L4 × 0.110) + (L5 × 0.054)
+ (L6 x 0.022) + Q
AWS
When the GHP is connected to direct expansion indoor units:
Charge amount (kg) = (L1 × 0.353) + (L2 × 0.250) + ( L3 × 0.170) + (L4 × 0.110) + ( L5 × 0.054)

2) Refrigerant charging method
• Always charge the refrigerant as a liquid in the tank. Charging as
a vapor may cause a compositional change of the refrigerant, and
could result in a performance decline or a breakdown .
•Always use a refrigerant scale when charging the refrigerant.
using a charging cylinder may cause a compositional change of
the refrigerant, and could result in a performance decline or a
breakdown.
•To avoid cross-contamination with other oils types, make sure to
separate maintenance tools according to the type of refrigerant
used. In particular, never use the gauge manifold and charging
hose with other refrigerants (R22, R407C etc.)
CAUTION
When charging the refrigerant, be sure to wear a pair of leather gloves.
If the refrigerant touches your skin directly, it may cause a frostbite.
