4.UNIT INSPECTION This product has been inspected at the factory and released to the transportation agency without known damage. Inspect exterior of carton for evidence of rough handling in shipment. Unpack carefully. If damage is found, report immediately to the transportation agency. 5.EQUIPMENT PROTECTION FROM ENVIRONMENT The metal parts of the unit may be subject to rust or corrosion in adverse environmental conditions. This oxidation could shorten the unit life.
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. The condensing unit contains moving parts and can vibrate.

1.Tubing should be cut square. Make sure it is round and free of burrs at the connecting ends. Clean the tubing to prevent contamination from entering the system. 2.Make sure that both refrigerant stop valves at the outdoor unit are closed. 3.Push the tubing into the fitting until it stops. This prevents flux from getting into the system. 4.Remove the cap and Schrader valve core from the service port to protect the valve seals. 5.Wrap a wet rag around the valve stub before brazing. 6.
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. Proper evacuation assures a dry, uncontaminated system. Here is the recommended evacuation procedure: 1.

The condensing unit rating plate and the tables of "Physical and Electrical Specifications / Outdoor Units" (Table 1) provide pertinent data necessary for the selection of proper size electrical service and over-current protection devices. Table 6 provides data on the minimum copper wire size as a function of supply wire length and circuit ampacity.
11.If checking the unit on the heating cycle in the wintertime, when the outdoor coil is cold enough to actuate the defrost control, observe at least one defrost cycle to make sure the unit defrosts properly. 12.Check the refrigerant charge (see Instructions under "Charging the System"). 13.Replace service port caps. Service port cores are for system access only and will leak if not tightly capped. 14.Check unit for tubing and sheet metal rattles. 15.Instruct the owner on operation and maintenance.
