Install Filter Drier(s) and Moisture Indicator(s) —
Every unit MUST have a filter drier in the liquid line.
569J***D/E/F models require two filter driers (one in each
liquid line). Locate the filter drier(s) at the indoor unit, close to
the evaporator coil's thermal expansion valve (TXV) inlets.
569J units include
one (569J***A/B/G/H) or two
(569J***D/E/F) Puron-duty filter drier(s), shipped in cartons
attached to the unit basepan. Remove the filter drier(s) and
prepare to install in the liquid line(s) at the evaporator coil.
Do not remove connection fitting plugs until ready to
connect and braze the filter drier into the liquid line position.

Installation of liquid line moisture indicating sightglass in
each circuit is recommended. Locate the sightglass(es)
between the outlet of the filter drier and the TXV inlet.
Refer to Table 10 for recommendations on refrigeration
specialties.
In some applications, depending on space and convenience
requirements, it may be desirable to install 2 filter driers and
sight glasses in a single circuit application. One filter drier
and sight glass may be installed at A locations (see Fig. 9)
or 2 filter driers and sight glasses may be installed at B
locations (see Figs. 9 and 10).
Select the filter drier for maximum unit capacity and
minimum pressure drop. Complete the refrigerant piping
from the indoor unit to the outdoor unit before opening
the liquid and suction lines at the outdoor unit.
Install Liquid Line Solenoid Valve —
It is recommended that a solenoid valve be placed in the
main liquid line (see Figs. 9 and 10) between the condensing
unit and the evaporator coil. Locate the solenoid valve at the
outlet end of the liquid line, near the evaporator coil
connections, with flow direction arrow pointed at the
evaporator coil. Refer to Table 10. (A liquid line solenoid
valve is required when the liquid line length exceeds 75 ft
[23 m].) This valve prevents refrigerant migration (which
causes oil dilution) to the compressor during the off cycle, at
low outdoor ambient temperatures. Wire the solenoid in
parallel with the compressor contactor coil (see Figs. 9 and
10). This means of electrical control is referred to as
solenoid drop control.
