    Introduction: the ev series uses a scroll compressor and refrigerant r- 410a to achieve high efficiency levels, quiet operation and reliable performance. The new refrigerant provides performance similar to that of r- 22 with one major advantage. Refrigerant r-410a is an hfc so it does not contain an...

    Some applications require an attic floor installation of the horizontal unit. In this case the unit should be set in a full size secondary drain pan on top of a vibration absorbing mesh. The secondary drain pan prevents possible condensate overflow or water leakage damage to the ceiling. The seconda...
