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 PITCH SUCTION LINE TOWARD OUTDOOR UNIT 1/2" FRO EVERY 10' OF LINE OUTDOOR UNIT LIQUID LINE INVERTED LOOP LIQUID LINE OUTDOOR UNIT SUCTION LINE Only refrigeration-grade copper piping (dehydrated and sealed) should be used. Take extreme care to keep the refrigerant tubing clean and dry prior to and during installation. If in doubt, blow out the tubing with dry nitrogen to remove any chips or debris before connection.
- Page 10 A fitting is on the liquid line to remove pressure. ! CAUTION - Heat Pumps are charged with refrigerant. Heat Pump liquid and suction valves are closed to contain the charge within the unit. Do not force the valve stem against the retaining ring. If the valve stem is backed out past the retaining ring, system pressure could force the valve stem out of the valve body and possibly cause personal injury.

Page 11: Refrigerant Metering Devices
Refrigerant Metering Devices Replace the existing indoor unit fixed orifice with the orifice supplied with the outdoor unit. See table 4 for the fixed orifice size for each unit. Table 4 outdoor model HR18D2VAR HR24D2VAR HR30D2VAR HR36D2VAR Fixed orifice size... - 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.

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. -
