If there is a possibility that condensation on the shutoff valve might drip down into the indoor unit
through gaps in the insulation and piping because the outside unit is located higher than the
indoor unit, it can be prevented by caulking the connections.
(Refer to figure 26)
The piping lead-out hole lid should be attached after opening a knockout hole.
(Refer to figure
27)
If small animals or debris enters the unit through the piping lead-out hole, close the hole with
blocking material (procured on site) after completion of
10.2.5 Additional Refrigerant Charge
and Check Operation. (Refer to figure 30)
Note:
After knocking out the holes, we recommend you remove burrs in the knockout holes
(See
figure 27)
and paint the edges and areas around the edges using the repair paint.
10.2.5 Additional Refrigerant Charge and Check Operation
The outside unit is charged with refrigerant when shipped from the factory, but depending on the
size and length of the piping when installed, it may require additional charging.
For charging the additional refrigerant, follow the procedures in this chapter and then perform the
check operation.
Note:
Total amount of refrigerant should be 220 lbs (100 kg) or less
10.2.5.1Before working
[About the refrigerant tank]
Check whether the tank has a siphon pipe before charging and place the tank so that the
refrigerant is charged in liquid form.
(See the figure below.)
