(3) Energy labeling “Class A” MHI models have cleared the class A standard, the highest energy saving level, with their high COP (coefﬁ cient of performance). (4) The microcomputer chip is installed in the indoor unit and outdoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced.

When a vacuum air purge is completed, remove the valve rod cap nuts and open the service valves (both liquid and gas sides) as illustrated below. After you have made sure that the valves are in the full-open position, lighten the cap nuts (for the valve rods and charge ports).
Page 227: Drain Piping Work
(b) Charging refrigerant 1) Since R410A refrigerant must be charged in the liquid phase, you should charge it, keeping the container cylinder upside down or using a refrigerant cylinder equipped with a siphon tube. 2) Charge refrigerant always from the liquid side service port with the service valve shut. When you ﬁ nd it difﬁ cult to charge a required amount, fully open the outdoor unit valves on both liquid and gas sides and charge refrigerant from the gas (suction) side service port, while running the unit in the cooling mode.

MAINTENANCE DATA 1.6.1 Servicing (1) Evacuation The evacuation is a procedure to purge impurities, such as noncondensable gas, air, moisture from the refrigerant equipment by using a vacuum pump. Since the refrigerant R410A is very insoluble in water, even a small amount of moisture left in the refriger- ant equipment will freeze, causing what is called ice clogging.
Page 240: Trouble Shooting For Refrigerant Circuit
(2) Refrigerant charging After the evacuation shown in the above, change the connection of the charge hose to the refrigerant cylinder. (b) Purge air from the charge hose First loosen the connecting portion of the charge hose at the gauge manifold side and open valve 3 for a few seconds, and then immediately retighten it after observing that gas has blown out from loosened connecting portion.

(3) Energy labeling “Class A” MHI models have cleared the class A standard, the highest energy saving level, with their high COP (coefﬁ cient of performance). (4) The microcomputer chip is installed in the indoor unit and outdoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced.
