Insulation of Refrigerant Tubing
IMPORTANT |
|
|
| |||
Because capillary tubing is used in the outdoor unit, both the |
|
| ||||
wide and narrow tubes of this air conditioner become cold. To |
|
| ||||
prevent heat loss and wet floors due to dripping of |
|
| ||||
condensation, both tubes must be well insulated with a | Thickness: | |||||
proper insulation material. The thickness of the insulation | Min. 8 mm | |||||
should be a min. 8 mm. | After a tube has been insulated, |
|
| |||
Wide tube | ||||||
|
|
| ||||
| CAUTION |
| never try to bend it into a narrow | |||
|
|
|
| |||
|
|
| curve because it can cause the tube |
|
| |
|
|
|
|
| ||
|
|
| to break or crack. |
