Indoor Drain Piping
The Sapphire indoor wall unit uses a gravity drain system. There is no internal condensate pump.
The drain hose must slope downward with no kinks, raises or fluctuations.
NOTE:
The drain tube cannot be field re-located from the Left to the Right side of the indoor unit.
PIPING INSTALLATION
1. Connect the field supplied drain hose to the
outlet pipe of indoor wall unit. A field supplied
transition or adapter may be required.
2. Apply pipe insulation to the entire drain line
and joints to prevent sweating.
3. The through-wall hole for the drain hose must be lower than the indoor wall unit drain
outlet for a functional gravity drain system.
4. Install field supplied drain hose with a downward slope from the Indoor wall unit drain
outlet to the drain hose outlet.
5. Route the condensate drain hose in the safety location to dispose of the condensate water.
