Outdoor Unit Installation
1) Connect projection side of charging hose (which comes from gauge manifold) to gas stop valve's service port.
2) Fully open gauge manifold's low-pressure valve (Lo) and completely close its high-pressure valve (Hi).
(High-pressure valve subsequently requires no operation.)
3) Do vacuum pumping and make sure that the compound pressure gauge reads –0.1MPa (–76cmHg).*1
4) Close gauge manifold's low-pressure valve (Lo) and stop vacuum pump.
(Keep this state for a few minutes to make sure that the compound pressure gauge pointer does not swing back.)*2
5) Remove caps from liquid stop valve and gas stop valve.
6) Turn the liquid stop valve's rod 90 degrees counterclockwise with a hexagonal wrench to open valve.
Close it after 5 seconds, and check for gas leakage.
Using soapy water, check for gas leakage from indoor unit's flare and outdoor unit's flare and valve rods.
After the check is complete, wipe all soapy water off.
7) Disconnect charging hose from gas stop valve's service port, then fully open liquid and gas stop valves.
(Do not attempt to turn valve rod beyond its stop.)
8) Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the specified torques.

*2. If the compound pressure gauge pointer swings back, refrigerant may have water content or a loose pipe joint may exists.
Check all pipe joints and re-tighten nuts as needed, then repeat steps 2) through 4).

Refilling the refrigerant
Check the type of refrigerant to be used on the machine nameplate.
Fill from the gas pipe in liquid form.
Important information regarding the refrigerant used
This product contains fluorinated greenhouse gases.
Do not vent gases into the atmosphere.
R32
Refrigerant type:
(1) 675 (1)
GWP value:
GWP = global warming potential
Please fill in with indelible ink,
the factory refrigerant charge of the product,
the additional refrigerant amount charged in the field and
the total refrigerant charge
tCO eq calculation according to the formula (rounded up
2
to 2 decimal places)
on the refrigerant charge label supplied with the product.
NOTE
National implementation of EU regulation on certain fluorinated greenhouse gases may require to provide the appropriate official national language on the unit.
Therefore an additional multilingual fluorinated greenhouse gases label is supplied with the unit. Sticking instructions are illustrated on the backside of that label.
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant charge of the unit is indicated both in weight and
CO equivalent.

Formula to calculate the quantity in CO
Use the GWP value mentioned on the refrigerant charge label. That GWP is based on the current legislation on fluorinated greenhouse
gases. The GWP mentioned in the manual might be outdated.
