Connect condensing unit to a fan coil unit using
field-supplied refrigerant grade tubing. Do not use
damaged or contaminated tubing. Evacuate or
purge field-supplied tubing.
The 38 JB is shipped with a holding charge in the
condensing coil and compressor. When using head
pressure dampers, connect line to head pressure-

charging.
CONNECT REFRIGERANT LINES — See Fig. 5.
When suction lines are piped thru the front or top
of the 38JB016, one 1-3/8 in. 90° elbow is required;
two 1-1/8 in. 90° elbows are required on the
38JB024. See Fig. 6 for hole locations.
When liquid lines are piped thru the front of unit
elbows are not required. When liquid lines are piped
thru top of unit, two 5/8-in. 90° elbows are
required. See Fig. 1 and Fig. 6 for line locations.
