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.
