Not too much tilt though. Some are designed to hold condensate. The water runs out into the condenser section and a ring on the condenser fan blade scoops the water and slings it onto the condenser coil to help cool it and lower the head pressure, thus making it more efficient. If there is no ring on the fan of the unit you end up with then drain away!
