CAUTION! When opening valve
stems, turn the hexagonal
wrench until it hits against the
stopper. Do not try to force the
valve to open further.
6.1.3 Note on adding refrigerant
Some systems require additional charging
depending on pipe lengths. The standard pipe
length varies according to local regulations.
For example, in North America, the standard
pipe length is 7.5m (25’). In other areas, the
standard pipe length is 5m (16‘). The refrigerant
should be charged from the service port on the
outdoor unit’s low pressure valve. The additional
refrigerant to be charged can be calculated using
the following formula:
Additional refrigerant per pipe length

For R290 refrigerant unit, the total amount
of refrigerant to be charged is no more than:
387g(<=9000Btu/h), 447g(>9000Btu/h and
<=12000Btu/h), 547g(>12000Btu/h and
<=18000Btu/h), 632g(>18000Btu/h and
<=24000Btu/h).
A
CAUTION! DO NOT mix
refrigerant types.

7 Electrical and gas leak checks
7.1 Before test run
Only perform test run after you have completed
the following steps:
• Electrical Safety Checks – Confirm that the
unit’s electrical system is safe and operating
properly
• Gas Leak Checks – Check all flare nut con-
nections and confirm that the system is not
leaking
• Confirm that gas and liquid (high and low pres-
sure) valves are fully open
7.2 Electrical safety checks
After installation, confirm that all electrical wiring
is installed in accordance with local and national
regulations, and according to the Installation
Manual.
Before test run
Check Grounding Work
Measure grounding resistance by visual detection
and with grounding resistance tester. Grounding
resistance must be less than 0.1. Note: This
may not be required for some locations in North
America.
During test run
Check for Electrical Leakage
During the Test Run, use an electroprobe and
multimeter to perform a comprehensive electrical
leakage test.
If electrical leakage is detected, turn off the unit
immediately and call a licensed electrician to find
and resolve the cause of the leakage.
C
This may not be required for
some locations in North America.
All wiring must comply with local
and national electrical codes, and
must be installed by a licensed
electrician.
7.3 Gas leak checks
There are two different methods to check for
gasleaks.
Soap and Water Method
Using a soft brush, apply soapy water or liquid
detergent to all pipe connection points on the
indoor unit and outdoor unit. The presence of
bubbles indicates a leak.
Leak Detector Method
If using leak detector, refer to the device’s
operation manual for proper usage instructions.
C
After confirming that the all pipe
connection points do not leak,
replace the valve cover on the
outside unit.
A: Low pressure stop valve
B: High pressure stop valve
C& D: Indoor unit flare nuts
