4/29/2014Condensate Accessory Installation 2014 Daikin North America, LLCSlide 85Before You Start Installing Condensate Pump Installing a condensate pump behind a wall mount unit requiresspecial consideration due to the limited amount of space left overafter running the line set and line voltage behind the unit. If line set has to go out the left hand side of unit, follow the sameinstructions listed within for the right hand exit. Drain tubing lengthsmay very depending on materials used for line set, high voltage anddrain. Cut lengths of tubing as you assemble drain and line set. When exiting on left side use one piece of ½” insulation to cover boththe liquid and suction lines behind unit. This will give you more roomfor the pump and float assembly. After you exit unit increaseinsulation back to ¾” wall and insulate the liquid and suction linesseparately. After install, prime pump before starting unit. 2014 Daikin North America, LLCSlide 8643
