INSTALLATION NOTES
To ensure the safety of the operator, ice cream machine the external power supply leakage protection
device must be installed.
The machine indoor installation, please do not use water spray or damp place installation of ice
cream machine, otherwise it will result in severe shock.
●Air-cooled machine
All the machines must maintain at least 50 cm gap. This will make the air flowing through the
condenser enough. If there is not enough space, permanent damage to the refrigerating capacity will
reduce the ice cream machine and may cause the compressor
●Electrical connections
To install each ice cream machine according to the requirements of the rated power, current and voltage on
the nameplate label electrical specifications.
Caution: This machine must be properly grounded! Otherwise it will cause an electric shock and
causing serious bodily harm!
If look into the freezing cylinder, the stirring shaft must rotate in a clockwise direction.
Note: To perform the following steps by trained repair technicians.
SAFETY MEASURES
Important note: not strictly abide by the safety regulations may result in heavy casualties.
Failure to comply with this warning will damage the machine and parts. Component damage will increase
the replacement of parts and service repair expenditure.
Safe operation:
HOMMY ENTERPRISE (XINHUI) CO., LTD.
http://www.hommy.com 4-32
Do not operate ice cream machine before reading the instructions. Do not follow this instruction
will cause damage to the equipment, ice cream machine performance or injuries.
● Do not operate improperly grounded ice cream machine.
● Do not perform any repair work on the ice cream machine before disconnect the mains, otherwise it will
cause an electric shock. If you need to repair, please contact your local dealer or find a professional repair
personnel.
Do not follow these instructions could result in electrical shock or damage to the machine,
please to electrical consulting.
Don’t rinse, wash and clean the machine under the water faucet directly, otherwise, someone
would get a bad electric shock.
The machine must be placed on a level surface, otherwise it may cause injury to persons or
damage to equipment.
● Do not allow to operate the machine by no training personnel.
● Before cut off the power supply, do not remove the throat block, the stirring shaft or transmission shaft.
● Do not place objects or finger into the throat block outlet
Do not follow these instructions can lead to products because of dangerous moving parts to cause serious
injury to personnel.
Be especially careful when removing the stirring shaft (turn off the power before the
operation), otherwise it may cause personal injury

MATTERS NEEDING ATTENTION
●Matters needing attention before using ice cream machine:
1. The machine is subject to shocks in the transport process, the best first place 24 hours before use.
2. Different machine has different ability to adapt to different types of environmental temperature, and
must be avoid direct sunlight and away from the heat source.
3. The material temperature after pouring into the hopper is suggested to cool down to 2℃-4℃before
making ice cream, so conducive to the material preservation and the taste improvement.
4. The machine should choose a place with good ventilation, and place on a level surface..
5. The rotation direction of the stirring shaft should be in clockwise.
6. The air inlet on the machine (left / right / rear plate) must keep with good ventilation.
7. The dust on the condenser to be cleaned regularly, the best cleaning once every month.
8. Matters needing attention for air-cooled machine: There are 50 cm above the space in which air flows
into the machine should be on the side of machine, the bottom of the machine can not have other objects
block, in order to ensure the machine cooling.
9. When the freezing cylinder has no material or lack of material, the machine can not enter the
refrigeration function.
10. The machine is not used for a long time, please unplug the power line or the external power switch off.
●Matters needing attention for the power line:
a) Machine shell must be grounded.
b) When the use of a supply voltage is 200V~240V, the cross-sectional area is not less than 4mm2 power
line, to ensure that the current adequacy. Because of the large starting current, so the total capacity of
outside power supply line load power requirements.
c) When the use of three-phase is 380V/50HZ power supply, the cross-sectional area is not less than
2.5mm2 power line, to ensure that the current adequacy. Because of the large starting current, so the
total capacity of outside power supply line.
HOMMY ENTERPRISE (XINHUI) CO., LTD.
http://www.hommy.com 6-32
Note:
1. The power supply capacity of power line or lack of the load voltage is reduced, affect the normal use of
the machine, and even damage;
2. If you are replacing the power line, must find the power line in accordance with the standard and
professional electrical repair personnel replacement
Warning:
The design of the ice cream machine is in the room (21~28 ℃) of the normal temperature operation. The
machine may reduce production or the dispensing ice cream becomes softer if run successfully at 32 ℃
under high ambient temperature.

STAINLESS STEEL EXPANSION TUBE
After cleaning the hopper, firstly coat a little lube on the positions of the sealing rings on the
expansion tube, then insert one end into the feed opening in the hopper. The air intake on
the expansion tube is adjustable as needs: φ4, φ6, and φ8.
Note:
1) When the first production of ice cream every day, until material is filled in 3/2 hopper,
shall be closed the expansion tube the air intake at all, when ice cream is finished, the air
intake can be set to adjust the position you want. (The ice cream overrun is lower from
φ4, φ6 to φ8.)
2) When using the expansion tube, the material can not be dense, otherwise the material
may not enter into the cylinder, causing the machine is not working properly.

●In cleaning and disinfecting
Cleaning and disinfecting schedules should be
managed by your local management, and
must strictly abide. In the cleaning and
disinfecting process, should emphasize the
following points.
It must clean and disinfect every
week.
1. Regular thorough cleaning and disinfecting
machine, including completely remove
and clean with the brushes.
2. All brushes provide a thorough cleaning.
3. Thorough cleaning the rear bearing sleeve
behind the cylinder, and the air pump
assembly and the throat block assembly.
4. The right to cleaning and disinfection liquid,
carefully read and follow the instructions
on the label. The cleaning liquid is too
strong may damage the parts, cleaning
liquid is too weak to be unable to provide
adequate cleaning or disinfecting.
●Routine maintenance and
checking
1. Replace damaged gaskets in throat block
or plugs.
2. Throw away the gasket which is wear,
broken or loose, and replace the new ones
to work.
3. For the water cooling machine, check
whether there is leakage or kink on the
soft water pipe. In the cleaning and
maintenance of machines when moving
back and forth may happen kink, soft
water pipe is damaged or broken should
only be replaced by professional staff.
