2. Remove the caps and turn the valve stem clockwise to seat the valve in the closed position.
3. For 2–5 ton models, use the valve access ports to reclaim the refrigerant trapped in the lines
between the pairs of shut-off valves.
CAUTION
Use a TUBING CUTTER ONLY - do not use a hacksaw to cut refrigerant tubing. Otherwise serious
damage can occur to refrigeration system!
4. For 2–5 ton models, cut the refrigerant line sections between the pairs of shut-off valves.
It is recommended to make this cut where accessibility is greatest - in the condensing section
of the unit. This allows the best access for reconnection or attachment of an extended line set
in the case of a split system.
5. Remove the interconnecting wiring between the evaporator and condenser electrical panel.
Disconnect the wire terminations in the condenser electrical panel, and pull the excess wire
into the evaporator panel.
6. Remove the threaded wire bushing connecting the two electrical panels.
7. Remove the unit top-joining strip. Take care to remove only those screws that attach the
joining strip to the evaporator and condenser cabinets.
8. Remove the two side cross-member angles.
9. Carefully pull the evaporator section away from the condenser section. Take care not to
damage the short lengths of refrigerant tubing extending into the condenser section.
The separated evaporator and condenser modules can now be individually moved to the desired
location for re-assembly or separately located for split applications. Splitting units with couplings
requires a mating coupling kit. See Table 2. For split installations, the cross member angles must be
field cut for each section length and re-attached.
