21InRow Air Cooled RD Installation
Connect refrigerant lines
Be sure to use only clean, refrigerant-grade (ACR Type L) pipe and follow standard procedures for pipe
size selection for air-cooled equipment. The maximum allowable equivalent length between the
evaporator and condenser is 61 equivalent m (200 equivalent ft). Vertical runs (hot gas) require a trap
every 6 m (20 ft) of rise.
Note: When brazing field-installed copper refrigeration lines, use a nitrogen purge to
minimize contamination of the refrigeration system during the brazing process.
The air-cooled equipment has been dehydrated at the factory and is shipped with a holding charge of
207 kPa (30 psig) nitrogen. Test refrigerant connections for leaks before replacing the holding charge.
Connect both refrigerant lines to the equipment, using provided fittings. See “Install kit” on page 5.
Condenser
Install and pipe the condenser in accordance with the provided instructions.
Flooded receiver
Install the flooded receiver in accordance with the instructions included with the kit.
Note: Install a 3/8" Schrader port on the liquid line outlet of the flooded receiver,
approximately 152 mm (6 in) downstream of the service port.
