Disassembly
16 CVHS-SVN04E-EN
9. Support compressor on wood blocks or plywood to
prevent damage to the compressor or wrap pipe
components.
10. Remove the compressor/motor assembly. Remove the
two locating roll pins from the compressor and/or
compressor base. Grip each pin and pull out of its hole;
at this point, remove the compressor/motor assembly.
Economizer Removal
Use the following steps to remove the economizer if
additional horizontal clearance is required.
1. Support the weight of the economizer with a movable
floor jack. Do NOT lift the economizer; simply support
it. Maximum economizer weight is provided in
Table 1,
p. 8 ; also see submittal.
2. If the unit has insulation, remove the insulation and
loosen the hex head screws on the condenser liquid
line flange. Loosen the hex head screws on the
evaporator liquid line flange. See
Figure 15 . Do NOT
remove the screws at this time.

NOTICE
Handle with Care!
Failure to follow instructions below could result in
equipment damage.
The cast iron base of the compressor and the discharge
flange of the volute can be broken easily if rough
handling of the compressor/motor assembly is allowed.
Take great care to prevent this breakage when removing
the compressor/motor assembly and setting it down, or
when moving it laterally on the floor (e.g., on rollers, etc).
Take extra care to gently sit the compressor/motor
assembly down and avoid letting it swing or drop into an
obstruction while lifting or moving it.
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift
component could result in component dropping and
possibly crushing operator/technician which could
result in death or serious injury, and equipment or
property-only damage. Ensure that all the lifting
equipment used is properly rated for the weight of the
component being lifted. Each of the cables (chains or
slings), hooks, and shackles used to lift the component
must be capable of supporting the entire weight of the
component. Lifting cables (chains or slings) may not be
of the same length. Adjust as necessary for even
component lift.
WARNING
Refrigerant under Positive Pressure!
Failure to follow instructions below could result in an
explosion which could result in death or serious injury
or equipment damage. System contains refrigerant and
may be under positive pressure. Recover refrigerant to
relieve pressure before opening the system. See unit
nameplate for refrigerant type. Do not use non-
approved refrigerants, refrigerant substitutes, or
refrigerant additives.
