Transportation and Storage

Upon receipt of the equipment, check for visible

damage. Make a notation on the shipper’s delivery

ticket before signing. If there is any evidence of rough

handling, immediately check for concealed damage. If

any damage is found, notify the carrier within 48 hours

to establish your claim and request their inspection and

a report. Then contact the Mammoth Service depart-

ment at [phone] or [e-mail]

for a warranty claim number.

Do not stand or transport the unit on end. In the

event that elevator transfer makes up-ended position-

ing unavoidable, absolutely ensure that the unit is in

the 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 pat-

terns will not harm units. Excessively high tempera-

tures, 140°F (60°C) and higher, may deteriorate certain

plastic materials and cause permanent damage.

Installation

General

1. To prevent damage, this equipment should not be

operated for supplementary heating and cooling

during the construction period.

2. Inspect the unit for any specific tagging numbers

indicated by the factory per a request from the in-

stalling contractor.

3. Check the unit nameplate for the size and voltage

rating and confirm against the plans that the unit is

being installed in the correct location.

4. Verify the installation location with the piping, sheet

metal and electrical contractors prior to installation

5. Verify all clearances are available for the unit prior

to installation.

6. Note the location and routing of water piping, con-

densate drain piping, and electrical wiring. The lo-

cations of these items are clearly marked on sub-

mittal drawings.

7. Mammoth recommends the unit be covered during

construction to protect components from dust and

other harmful material. This is critical while spray-

ing fireproofing material on bar joists, sandblasting,

spray painting and plastering.

Unit Location

Locate the unit in an area that allows for easy removal

of the filter and access panels. Leave enough space for

service personnel to perform maintenance or repair.

Provide sufficient room to make water, electrical and

duct connections. Refer to submittal drawings for

proper service clearance dimensions. Install unit in

compliance with all state and local codes.

NOTE:

Check the unit name plate for correct voltage with the

plans before installing the equipment. Make sure all

electrical ground connections are made in accordance

with local code.

IMPORTANT:

Mammoth V-Cube Slim™ units should be installed only

by qualified personnel, experienced in the installation

of this equipment and related systems. Read these

instructions carefully before unpacking, installing and

operating this unit

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.

Figure 1—Electrical Control Panel Bolts

Remove the bolts used

to mount the electrical

cabinet to the main unit

sections. There are 6

bolts on the side of the

unit.

MAMM-VCS-IOM-1EB (October 2011)

Step 2 – Remove optional coil section

This step only applies to units with a waterside econo-

mizer or hot/chilled water coil.

Remove the bolts that connect the welded base of the

water coil section to the welded base of the main cabi-

net section.

Remove the access panels on each side of the water

coil cabinet shown in Figure 2. Inside the water coil

section, disconnect wiring to any valves and/or air sen-

sors that run to the other sections in the unit.

Once all electrical connections to the other sections in

the unit have been removed, loosen and remove the

section bolts that fasten the water coil cabinet to the

main cabinet section. Set the water coil section aside,

away from the unit to help prevent damage during the

remaining disassembly process.

Step 3 – Removing the blower cabinet

Remove the main cabinet access panels (Figure 3).

Feed any wiring for the blower motors and/or air sen-

sors passing through the refrigeration/condensing sec-

tion through the chase way into the blower cabinet.

Remove the section bolts that attach the blower cabinet

to the refrigeration/condensing section (Figure 3).

Figure 2—Optional Coil Section Removal

Remove the water pipe extensions at the Victaulic con-

nection point inside the unit. Attach lifting straps to the

motor mount plate as shown in Figure 4 and attach to a

spreader bar or forklift fork. Also attach ropes or chains

to the eye bolt on one of the motors and attach to each

end of the spreader bar or fork to level the load of the

blower section.

Use these instructions in the reverse order for assem-

bly. Replace any torn or damaged gasket with new

material. Apply a bead of silicon caulking between sec-

tions while reassembling to minimize air leaks.

For further information or assistance with these proce-

dures, contact the Mammoth Service department.

CAUTION!

Lifting straps are to be used in lifting the blower section

only. Do not attach eye bolts to the motor mount plate

and attempt to lift the blower section. Failure to do so

can result in equipment damage and personal injury.
