1.4 Working Conditions
The following conditions are requested to ensure long term and steady operation:
Voltage fluctuation: ≤ ±10%
Ambient temperature: 0~35°C
Cooling water temperature: 5~30°C
Cooling water pressure: 1~8 bar
Max relative humidity: 85% ( without moisture condensation)
_________________________________________________________________________
CAUTION
The machine is not designed to work under condition of explosion-proof
standards. Thus make sure the working place is out of explosive danger.
MEHEN is NOT responsible for any accident happened to people or machine in
case the machine is used out of the designed condition.
_________________________________________________________________________
CHAPTER 2 INSTALLATION
2.1 Position
The machine shall be installed to a flat place and lock the caster
immediately after the machine is positioned.
2.2 Installation of Air-cooled Machine
The machine must be installed in room with a good
air-ventilation so as to dispel the hot air generated by the
condenser. The room would be better with enough space for
operators to withdraw when necessary.
WARNING
Machine with air-cooled condenser must be installed no less
than 50 cm from the wall in order to allow free air circulation
around the condenser.
Clean the floor near and under the machine to avoid paper
and other stuffs entering into the condenser and blocking
a regular air flow.
Insufficient air circulation affects both machine working and
its performance.
2.3 Installation of Water-cooled Machine
The inlet and outlet pipes of cooling water must be properly installed before the
machine can be used.
The requirements for the cooling water are:
Pure and no debris
It's better to use soften water to prevent that furring appears inside of the
pipe to block the pipe and reduce the heat-exchange-efficiency
Pressure range: 1 ~ 8 bar.

- 8 -
Connect the cleaning water pipe to a drinkable water source if the machine is
equipped with a cleaning tap.
NOTE
MEHEN recommends to use steel pipe which can bear pressure up to 8 bar.
Keep the pipes fluent, don't bent.
There is electric water valve inside which can cut the water flow, keep the
water tap open before running the machine.
2.4 Electrical Connection
Before connecting the machine to the power mains, check power information
indicated on nameplate and choose a suitable power supply to the machine.
Get a circuit breaker protection device according to the parameters on nameplate
and install it to the power supply circuit.
WARNING
The PE must be connected to a good ground outlet.
2.5 Change Cable
If machine main cable is damaged, it must be replaced with same features or
minimum diameter is no less than 5 mm and carried out by an skilled technician.
2.6 Refrigerant Gas Refill
The freezing system has been filled with refrigerant gas and inspected by MEHEN
before delivery. If the machine met problem of gas leaking in use, a skilled
technician should be got to find the leakage, fix it then refill the refrigerant gas.
2.7 Machine Testing
Each machine from MEHEN is tested with full record before delivery. After the
machine is installed properly at the clients working site, it should be inspected
and tested by a skilled technician.
Connect the inlet and outlet of the water, keep the water tap open,
Prepare proper quantity (half of the whole capacity) water and pull into the
mix tank,
Connect the power and power on, the will enter Home ,
Press Mix on Home page to test the Beating function, test all the four
beating mode, press Stop and Home to exit after make sure they can switch
normally,
Press COOK on Home page to test the Cooking function, press Stop and
Home to exit after make sure the temperature can increase normally,
Press COOL-AGEING on Home page to test the Cooling function, press
Stop and Home to exit after make sure the temperature can decrease
normally.

TIPS
All the parameters after the first ‘END’ will be invalid.
If set the ‘ALARM’ out the range of starting and target-temperature, the
machine will not alarm during that ‘STEP’.
4.9 Mix Tank Cover Open Alarm
During working progress, a message ‘COVER OPEN’ will appear if the mix tank
cover is open. (refer to picture left below)
TIPS
After the tank cover is open:
The machine will keep on working if the user parameter Cover open stop is
set to OFF.
If the Cover open stop is set to ON:
It will keep on working if the Mix-Temperature is below 50 °C.
It will stop working if the Mix-Temperature is not below 50 °C.
4.10 Power Failure
The controller will record the time and temperature when a power failure happens.
When the power supply recovers, the controller will firstly judge the mix inside of
the tank is good or not, then decide how to continue:
It will continue from the present STEP if the mix is good,
It will start a whole processing if the mix goes bad.
TIPS
The background color of STEP will turn to red to remind that a power failure
happened after power recovery.(see picture right above in front page).
4.11 Error Alarm
It will stop and show message when an error detected. Press Reset to exit.
TIPS
It will display the certain detected error only.

CHAPTER 8 MAINTENANCE
8.1 Routine Maintenance
_________________________________________________________________________
CAUTION
Any service operation requiring the opening of machine panels must be carried
out with machine in stop position and disconnected from main switch!
Cleaning and lubricating moving parts is prohibited!
Repairs of electrical and freezing plants must be conducted by skilled technician!
_________________________________________________________________________
8.2 Maintenance of Water-cooled Machine
For machine with water cooling condenser has to been stored up at the end of
selling season, the water inside the pipe should be drained out. Otherwise, if the
outside temperature falls under 0°C, the water inside may be frozen and damage
the pipe of the machine.
8.3 Maintenance of Air-cooled Machine
Use a long-haired brush or a bolt of compressed air to clean the condenser
regularly and remove dust, paper other stuffs inside.
_________________________________________________________________________
CAUTION
When using compressed air, operators should take personal protections in order
to avoid accidents; To wear safety goggles is advised for safely purpose!
Never use sharp metal objects to clean the condenser which may damage the
system; The efficiency of condenser is highly related to how clean it is.
_________________________________________________________________________
8.4 Preventive Maintenance
Check out the machine according to the following steps so as to prepare for a new
selling season.
Check the gas quantity of the freezing system to ensure the efficiency of freezing.
Make sure the tightness of the chamber and replace the seal if needed.
Use long-haired brush or compressed air to clear out the dust and other stuff on
the condenser.
8.5 Order Spare Parts
Replace the worn out parts timely to ensure the normal running.
To order new spare parts or any components, please contact with local distributor
designated by MEHEN or our service department directly.
