Verifying the correct electrical

Every Spaceman machine is shipped with a cord and plug.  It is necessary to have a licensed electrician install the correct receptacle, electrical line, and breaker to power your machine.  Supplying improper power to the machine will lead to machine failures not covered under warranty and may cause irreversible damage to electrical components on your machine.

Special Advisory:  It is very important to supply clean, stable power to the machine.  If you utilize a generator or live in an area susceptible to brown outs, power dips, power spikes, or other forms of "dirty" power, your machine may experience odd behavior.  In some cases, these issues can be resolved by upgrading the building wiring (such as is older buildings), and in other cases require extra equipment be added between the building power and your machine, such as a buck-boost transformer to stabilize the power.  If you are using a generator, it is important to supply sufficient power to prevent the voltage from dropping too low when high-amp-draw components such as the compressors turn on.

* Volts: These voltages are representative of the nominal voltage range the equipment is certified at.  This is the recommended voltage for all equipment for optimal performance.  The machines can, however, operate at an effective voltage range of +/- 10%, or: 104-126V for machines listed at 115V, and 200-242VAC for machines listed at 208-230V.  Operating outside of the nominal voltage range on this chart may lead to excess wear on the electrical components such as the motor and compressor and lead to premature failure.  If you have any concerns, please contact Spaceman USA Technical Support for further guidance.
** MFS = Maximum Fuse Size
*** MCA = Minimum Circuit Ampacity

Power Connection
  1. Verify incoming electrical supply is wired the same way on circuit breaker or wall receptacle before plugging in the machine or switching on power. 
    Note: For 220V, 1 phase machines, there will be two hots, and one ground.  For 110V, 1 phase machines, there will be one hot, one neutral, and one ground.  Please refer to the wiring diagram inside the machine side panel to verify wiring polarity.

  2. Connect all wires to the receptacle or circuit breaker (including neutral & ground bus terminals).  Follow local electrical codes and guidelines for proper wiring.
    Warning:  Always make sure electrical connections are secure and unable to be exposed to moisture, liquid, spillage, or other environmental dangers.  Always use a drip-loop or other approved methods of protecting electrical connections.
  3. Turn machine power on, and with the machine completely disassembled (all parts removed from the freezing cylinders), use the WASH mode to verify the motor(s) is turning in the correct direction.  There is a small red arrow on each motor pulley to indicate proper rotation direction.
    Special Note:  For 3-Phase machines ONLY, if the motor direction is not turning in the direction, switch any two of the L1, L2, and L3 lines wired on the plug or receptacle to reverse motor direction and repeat step 3.  The machine will NOT operate properly and will cause damage if the motor spins in the incorrect direction.
    Warning:  Operating the machine in WASH mode with panels off and/or the dispensing door off of the machine is dangerous.  Keep hands and tools clear of the inside of the machine and freezing cylinders at all times.  Serious injury or damage could occur.
