3. Pipe "c" diameter ( outdoor pipe diameter)
Note:
1.When the distance from outdoor to the longest indoor is over 30m, the main pipe should be the enlarged
diameter.
2. If pipe b diameter is larger than main pipe c, enlarge main pipe c diameter to be the same as pipe b.

Drain pipe disposal
• Make sure the drain works properly.
• In regions where buildups of snow can be expected, the accumulation and freezing of snow in the space between
the heat exchanger and external plate may lower operating efciency.
• After punching the knock-out hole, the application of repair-type paint on the surface around the edge sections is
recommended to prevent rust.

(1) When pipe length between indoor & nearest branch pipe ≥15m, adjust in accordance with following criteria:
①
If indoor rated capacity≤5.6kW, change gas / liquid pipe diameter to 15.88 / 9.52
②
If 16.8kW≥ indoor rated capacity>5.6kW, change gas / liquid pipe diameter to 19.05 / 9.52
③
If indoor rated capacity>16.8kW, change liquid pipe diameter to 12.7
