ITEMS TO ROUTE BEFORE INSTALLING THE EVAPORATOR UNITS
1.
Route the refrigerant lines from each evaporator unit toward each other using
1/2
"
OD copper tubing for the suction line and 1/4” OD
tubing for the liquid lines.
2.
Join both suction lines together using a
1/2"
T-fitting. Install a
5/8
” to
1/2
"
reducer at the outlet of the
T-fitting. The remainder of the
suction
line from the T-fitting to the condensing unit will need to be
5/8
” OD copper tubing.
3.
Join both liquid lines together using a
1/4"
T-fitting. Install a
3/8"
to 1/4” reducer at the inlet of the T-fitting. The remainder of the
liquid
line
from the T-fitting to the condensing unit will need to be
3/8"
OD copper tubing.
4.
Route the display cable from the desired location to the desired
primary
evaporator unit installation location
.
5.
Route the bottle probe cable from the desired thermostat bottle location to desired
primary
evaporator unit installation location
.
6.
Route the drain lines from a proper discharge location to desired evaporator unit installation locations
.
7.
Route the power cable wiring to the desired evaporator unit installation locations.
8.
Route an 18-5 thermostat wire between the desired evaporator unit installation locations.
