Provide a level concrete slab. To prevent transmission of noise or vibration, slab should not be connected to building structure. Some sort of sound-absorbing material should be placed between the condenser and the slab. A good material to use is rubber and cork pad. For rooftop application, make sure the building construction can support the weight and that proper consideration is given to the weather-tight integrity of the roof. - Page 9 OUTDOOR UNIT ADDITIONAL SUCTION LINE PITCH SUCTION LINE TOWARD OUTDOOR OIL TRAP FOR EACH 20 FOOT UNIT 1/2" FOR EVERY 10' OF LINE RISE OF PIPE INDOOR UNIT ABOVE OR LEVEL TO OUTDOOR UNIT LIQUID LINE MAX.

- Page 12 Evacuation All new installations must be evacuated to a deep vacuum in order that all noncondensible gases and moisture are removed prior to charging the system. Air in a system causes high condensing pressure, which increases power consumption and reduces performance. The presence of moisture in a system can render it inoperable in a very short time.
