7. Refrigerant piping work.
7-1 Cautions on pipe handling.
1) Protect the open end of the pipe against dust and moisture.
2)
All pipe bends should be as gentle as possible. Use a pipe bender for bending.
(Bending radius should be 30 to 40mm or larger.)
7-2
Selection of copper and heat insulation materials.
When using commercial copper pipes and fittings, observe the following:
1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 0.045kcal/mh˚C)
Refrigerant gas pipe’s surface temperature reaches 110˚C max.
Choose heat insulation materials that will withstand this temperature.
2)
Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.
In order to protect the environment, be sure to pump down when relocating or disposing of the unit.
1)
Remove the valve caps from liquid stop valve and gas stop valve.
2) Carry out forced cooling operation.
3) After five to ten minutes, close the liquid stop valve with a
hexagonal wrench.
4) After two to three minutes, close the gas stop valve and
stop forced cooling operation.
Forced cooling operation
1) Press the Forced Operation switch (SW1) to begin forced cooling.
Press the Forced Operation switch (SW1) again to stop forced cooling.
3) Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.
6. Refilling the refrigerant.
Check the type of refrigerant to be used on the machine nameplate.
Precautions when adding R410A
Fill from the liquid pipe in liquid form.
It is a mixed refrigerant, so adding it in gas form may cause the
refrigerant composition to change, preventing normal operation.
1)
Before filling, check whether the cylinder has a siphon attached or not.
(It should have something like “liquid filling siphon attached” displayed on it.)
Filling a cylinder with an
attached siphon
Stand the cylinder upright
when filling.
There is a siphon pipe
inside, so the cylinder
need not be upside-
down to fill with liquid.
Filling other cylinders
Turn the cylinder
upside-down when filling.
