the horizontal plane. |
|
|
|
|
If the slope exceeds the specified angle, the unit may be damaged. |

|

Pipe connection |
|
|
|
|
When connecting the twinning kit to the outdoor unit, note the following: |
|
|
|
·Make sure the pipes from the twinning pipe to the outdoor unit are sloped downwards (towards the twinning pipes).
·If the piping on the outdoor unit side (from the twinning pipe) exceeds 2 m [6 ft], ensure a trap (gas pipe only) within 2 m [6 ft].
Make sure the height of the trap is 200 mm [7-7/8 in] or more.
If there is no trap, oil can accumulate inside the pipe, causing a shortage of oil and may damage the compressor.
<2 m [6 ft] or less> |
<More than 2 m [6 ft] apart> |

4. Insulation Cover Installation
Install the insulation cover on the twinning kit after brazing the pipes and twinning kit.
Insulate all refrigerant pipes. Insulate the liquid and gas pipes separately, and pipes located inside the unit as well as the outside. Use heat-resistant insulation material (Heat resistant: at least 120 °C [248 °F], Thickness: liquid = 10 mm [13/32 in],
gas = 20 mm [13/16 in]). Position the edges of the insulation cover and heat-resistant insulation material so as not to leave a gap, and then wrap the exterior perimeter of the pipe joints and middle with tape (field-supplied).
