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.
Disassembly and Assembly General Guidelines Figure 1: Unit As Shipped 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.
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. Figure 3: Main Electrical Panel Removal Wiring All low voltage wires are connected using quick-connect plugs. 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 require handtools for removal.
2. If still in place, remove the coil cabinet inner access panel from the side of the cabinet. IMPORTANT! The gasket between the FANWALL section and the main chassis must be replaced before reassembling the section. Failure to do so may cause air leakage and poor unit performance. 3. Remove the six fasteners (three on each side) connecting the sides of the coil cabinet to the main chassis. 4.
Installation WARNING! The installer must determine and follow all applicable codes and regulations. 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. Mammoth recommends the unit be covered during construction to protect components from dust and other harmful material.

Return air ductwork may also be required. All ductwork should conform to industry standards of good practice as described in the ASHRAE Systems Guide.
Cleaning and Flushing Before building water is connected to the unit, the building water system must be flushed clean of particulate contaminants. Follow the procedures described in this section. IMPORTANT! Performance of WSHP units relies upon a building water supply filtered of any particulate and chemical contaminants. Before building water is connected to the unit, the building water system must be flushed clean of particulate contaminants.
Figure 9: Electrical Connection Points Field control wiring Operating Voltage Incoming power supply must comply with the data in Table 1. Unit operation outside of the Min/Max range is not recommended and will result in premature component failure. Table 1: Operating voltages Power wiring .
Electrical Refrigerant Piping Electrical Terminals Mammoth V-Cube Slim units with DX cooling are shipped fully charged with refrigerant from the factory. No piping connections are needed and no field charging is required prior to operation of the system. Check the following prior to startup: Tighten all electrical terminals per the torque value listed on the connector. Electrical terminals are located within the main unit control panel.
monitor is set correctly as indicated on the electrical wiring diagram provided with your unit. 1. Install refrigeration gauges on the compressor circuit to be started. Blowers and Fans 2. Turn the unit system switch to the on position. Switch the motor protectors for the supply air fans to the On position (see page 6 for motor protector locations). Turn the system switch to the On position, then carry out the following checks: 3.
Chilled Water, Hot Water and Steam Coils Startup Visually check the coils and system piping for proper installation and any signs of leakage. Repair as needed. Check motorized valves and linkages for the following points of operation. Controls Startup For controls startup procedures, see the EPIC® Sequence of Controls documentation that is included in the packet of information that is zip-tied to the inside of the main control panel.
