Disassembly and Assembly Instructions For
V-Cube Slim™ Units
V-Cube Slim units are designed to allow for
installation in new facilities and as a retrofit for older,
obsolete equipment.
Your new V-Cube Slim will come fully assembled. In
the event building layout prohibits the unit to be moved
to its final location as a whole assembly, it will be nec-
essary to disassemble the unit into its basic sections
and reassemble it at the final location.
The standard unit consists of three sections—the elec-
trical control panel, the refrigeration/condensing section
and the blower section. Units with an optional water-
side economizer or hot/chilled water coil will have an
additional section for that coil.
The disassembly of sections requires removal of the
3/8” bolts holding them together while supporting each
section as it is being removed with rigging equipment.
Step 1 – Remove the electrical panel
Unplug the wire harness that connects the EPiC™ key-
pad and reset buttons/selector switches from the panel
door to the main electrical panel. Remove the panel
door by lifting it from its hinges and carefully set aside,
away from the unit to help prevent damage during the
remaining disassembly process.
Unplug all control wiring harnesses that run from the
main electrical panel to the compressor section. These
plugs are labeled for correct re-installation. Finally,
remove all high voltage wiring to the fan motors.
Once all electrical connections to other sections in the
unit have been removed, make sure that the electrical
panel is supported from above or below to prevent it
from falling once the bolts that connect it to the main
cabinet sections are loosened and removed.
Loosen and remove the section bolts that fasten the
main electrical panel to the main cabinet sections
(Figure 1). Set the main electrical panel aside, away
from the unit to help prevent damage during the re-
maining disassembly process.
NOTE:
Please read all disassembly instructions completely
before starting any disassembly
DANGER!
A mechanical lift is required to move or lift all sections
of a V-Cube Slim™ unit. Do not attempt to move or lift
sections without a mechanical lift. Failure to do so can
result in equipment damage, severe personal injury or
death.
DANGER!
Lifting the entire unit (blower section, coil section, etc.)
using lifting lugs, eye bolts or straps attached to the top
of the unit can result in serious damage to the unit,
personal injury or death.
Lifting the entire unit should only be done using a fork-
lift or a strapping spreader bar mechanism attached to
the base of the unit.
DANGER!
It is mandatory that all utilities (water, electric, and
communication cables to the Building Management
System) be removed prior to unit disassembly. Follow
approved lockout/tagout procedures before any disas-
sembly of the unit. Failure to do so can result in elec-
tric shock, equipment damage, severe personal injury,
or death.
NOTE:
All blower wiring is correctly phased at the factory and
must be re-wired correctly upon re-assembly for cor-
rect compressor and blower operation. Mark all wires
and pull through knockouts using care not to scrape
the insulation of the wiring when separating sections. If
the wire insulation or wire jacket is torn during the dis-
assembly/re-assembly procedure, replace the wire. Do
not use wire that is missing insulation. Control and
sensor wiring use Molex plugs for proper polarity.

Remove the bolts used
to mount the electrical
cabinet to the main unit
sections. There are 6
bolts on the side of the
unit.
