NOTES AND FUNCTIONS OF YOUR MACHINE
The machine you have purchased is a gravity fed soft serve
machine. It is capable of producing a variety of products that
include: Soft Serve Frozen Yogurt, Ice Cream, select custard
products, and sorbets.
Product is poured into the refrigerated hopper (product
should be below 41°F) where it is kept until flowing into the
freezing cylinder via the air tube.
On the front of your machine is an digital control to regulate
and maintain consistent product quality for each flavor as an
analog rocker switch to power the board on or off.
Inside the freezing cylinder, the beater mixes the product while
freezing and produces a soft serve product.

ROUTINE MAINTENANCE OPERATIONS
Clean and Lubricate Daily
Replace Wearable Parts Every
1 to 3 months*
Internal Cleaning Quarterly**
* Based on machine usage and cleaning
intervals; a Tune-Up Kit is available with
all wearable parts (O-rings, gaskets, etc.)
except scraper blades
** Based on cleanliness of location
and proximity to powder-based
machines
For optimal machine performance and
many years of efficiency and reliability
from your machine, Spaceman USA
recommends cleaning and sanitizing the
machine and its parts daily. The machine
comes equipped with a brush kit
specifically designed to efficiently and
properly clean the machine.
Tune-Up Kit

IMPORTANT:
Cleaning and sanitizing
schedules are governed by state
or local regulatory agencies and
MUST be followed accordingly.
Routine maintenance MUST be
performed a minimum of once
every three days.
CAUTIONS:
Do NOT run the machine without properly lubricating
required parts.
Do NOT clean the machine with abrasive or toxic chemicals
and cleaners. Doing so may cause damage to the stainless
steel material.
ONLY use Spaceman-USA-included cleaning brushes and lubrication.
NEVER use metal objects to clean or operate the machine.
ALWAYS replace wearable parts a minimum of every 3 months.
ALWAYS prime machine prior to operating.
ALWAYS inspect parts for excess wear and damage.

SANITIZATION
IMPORTANT CAUTION
After sanitizing the machine, DO NOT
rinse or touch areas that have been
sanitized. Product must be added
immediately. If new product will not be
added immediately, rinse machine with
clean water and loosen door hand-
screws to allow cylinders to air-dry.
Sanitize machine before using again.
Always use food-grade, no-
rinse sanitizer (Stera-Sheen
green label or equivalent) to
sanitize. If warm water is
required to dissolve sanitizer,
allow the solution time to
cool before adding to
machine.

FROZEN PRODUCT OPERATION
FREEZE PRODUCT
Verify cylinder is full of mixed product and primed
Press FREEZE button
The motor will begin to agitate the product,
and the cooling system will begin to freeze
the product
Freezing product takes approximately 10 minutes
When product reaches the set viscosity, it is
ready to dispense (viscosity can be changed in
the Settings menu, Page 19)
IMPORTANT
Machine shuts down automatically if cylinders experience
freeze-up (usually because the viscosity is set too high for the
selected product) to prevent motor damage. Use the green reset
button to return the machine to normal operation.
PROPER MACHINE RESET
1. Switch power switch OFF
2. Press green reset button on side or back of machine
3. Wait 15 to 20 minutes; switch power ON
4. Press RESET, then WASH button on front
5. Observe machine performance and return to normal use if
functioning properly
CAUTION:
If machine makes any abnormal noise during reset,
immediately switch power OFF and contact service
NOTE:
If machine doesn't turn on, turn power OFF, wait 30 minutes, and
repeat steps 1 to 5. If problem persists, contact service team.

CONSISTENCY
What to do: Add air to the freezing cylinder by following
the closing/opening procedures in the previous column,
omitting Step 4.
Machines without air pumps can experience product
consistency changes if they go unused for an extended
period of time. Product may become icy or dense if left in
the freezing cylinder too long, often occurring during a
business’s longer slow-periods.
Spaceman USA Soft Serve Gravity Training

IMPORTANT
If temperature setting is too cold, product will freeze around the sides of the hopper and potentially cause damage.
Hopper temperature should be set above freezing between 37 and 40°F. Do not rely on the temperature display on
your machine. USE a food grade thermometer to measure the actual product temperature inside the hopper.
