Warnings, Cautions and Notices
Warnings, cautions and notices appear at appropriate
locations throughout this manual. Your personal safety
and the proper operation of this machine depend upon
the strict observance of these precautions. Read this
manual thoroughly before operating or servicing this unit.
WARNING! Indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
CAUTION! Indicates a potentially hazardous
situation which, if not avoided, could result
in minor or moderate injury. It could also be
used to alert against unsafe practices.
Receiving Inspection and Storage
When receiving equipment, check the Bill of Lading to
verify that all crates and cartons have been received.
Compare shipped-loose items received against the
list provided. Check for visible damage. If there is any
evidence of rough handling, immediately check for concealed damage. If any damage is found, refuse delivery
of the damaged item. Then contact your Mammoth Representative to place an order for a new unit or the repair
and reshipment of the damaged unit. It is encouraged
that detailed photos be taken for documentation.
This vertical unit must remain in an upright position at
all times. If this unit must be positioned horizontally during transport or rigging, it must be returned to its normal
upright position for at least 24 hours before operating.
IMPORTANT! Operating a unit after it has
been stored or transported on its side can
result in serious compressor damage which
is not covered under the equipment warranty. Make sure the unit is first returned to its
normal upright position for at least 24 hours
before operating.
Temporary storage at the job site must be indoors, completely sheltered from rain, snow, etc. High or low temperatures naturally associated with weather patterns will not
harm units. Excessively high temperatures, 140°F (60°C)
and higher, may deteriorate certain plastic materials and
cause permanent damage.
General Warnings
WARNING! Electric shock and moving equip-
ment hazard. Can cause severe injury or
death. Lock and tag out all electric power
before servicing equipment. More than one
disconnect may be required to de-energize
the unit.
CAUTION! Installation and servicing of this
equipment should only be undertaken by a
trained professional with experience working
on commercial HVAC systems. Contact your
Mammoth representative or the Mammoth Service Department for help in scheduling service.
CAUTION: Sharp edges on sheet metal, coil
surfaces and fasteners can cause personal
injury. Avoid contact and wear protective
clothing and gloves.
IMPORTANT! This product was carefully
packed and thoroughly inspected before
leaving the factory. Responsibility for its safe
delivery was assumed by the carrier upon
acceptance of the shipment. Claims for loss
or damage sustained in transit must therefore
be made upon the carrier as follows:
Visible Loss or Damage
If there is any external evidence of loss or
damage, refuse delivery of the damaged item.
Refusal of items must be noted on the freight
bill or carrier’s receipt, and signed by the carrier’s agent. Failure to adequately describe
such external evidence of loss or damage
may result in the carrier’s refusal to honor a
damage claim. The form required to file such
a claim will be supplied by the carrier.
Concealed Loss or Damage
Concealed loss or damage means loss or
damage which does not become apparent
until the product has been unpacked. The
contents may be damaged in transit due to
rough handling even though the carton may
not show external damages. When the damage is discovered upon unpacking, make a
written request for inspection by the carrier’s
agent within fifteen (15) days of the delivery
date and file a claim with the carrier.

Disassembly and Assembly
General Guidelines
The Mammoth V Cube Slim Split is engineered to be
disassembled in the field and moved through 36” doors
into position then reassembled without breaking into the
refrigeration circuits. Only qualified personel experienced
in operation and maintenance of HVAC equipment should
perform these procedures.
WARNING! This equipment presents hazards
of electricity, rotating parts, sharp edges,
heat and weight. Failure to read and follow
these instructions can result in property damage, severe personal injury or death. This
equipment must be installed by experienced,
trained personnel only.
WARNING! 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.
WARNING! 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 forklift or a strapping spreader bar mechanism attached to the
base of the unit.
WARNING! All utilities (water, electric, and
communication cables) must be removed
prior to unit disassembly. Follow approved
lockout/tagout procedures before any disassembly of the unit. Failure to do so can result
in electric shock, equipment damage, severe
personal injury, or death.
IMPORTANT! All blower wiring is correctly
phased at the factory and must be re-wired
correctly upon re-assembly for correct 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 disassembly/
re-assembly procedure, replace the wire. Do
not use wire that is missing insulation. Control and sensor wiring uses Molex plugs for
proper polarity.
Figure 1 shows the unit as shipped from the factory. Figure 2 shows an exploded view of the unit, equipped with
coil cabinets and 2” x 4 “ filter racks. Note that the coil
cabinets and refrigeration sections are resting on welded
steel bases. These bases are an integral part of the subassemblies and must not be removed.
IMPORTANT! The welded steel bases are
integral to subassembly stability and mobility.
Do not detach!

Mechanical lifting equipment is necessary to dismantle
and relocate the V Cube Slim Split. This unit will weigh
between 4000 and 5800 pounds depending on options
and features built into the unit at the factory.
Mechanical lifting equipment is also required to remove
the sub assemblies from the main chassis. Subassemblies weigh a minimum of 205 pounds and as much as
1500 pounds each.
Wiring
NEMA does not allow quick-connect plugs for power (high
voltage) wiring. For this reason, all power wires have raw
ends and are ‘hardwired’ to terminal blocks in the unit and
Filter Rack
require handtools for removal. These power wires must
be labeled prior to removal to avoid problems.
All low voltage wires are connected using quick-connect
plugs.
Piping
All water piping is iron with grooved (Victualic®) connections.
Refrigeration circuits are copper pipe and do not require
any disassembly and reassembly.
