General Information

The MAGAPOR range of containers for the preservation of semen is made up of the following models:

• Z-100
• Z-300
• ZG-500
• ZG-1400

Your Machine
The preservation unit you have chosen is specially designed and built to keep semen doses at a constant temperature. Temperatures ranging from 15 to 40ºC can be assigned.
The Z-300 is equipped with a based digital regulator, which controls the temperature inside the container. It also has an alarm system which allows the operator to check whether a serious deviation in temperature has occurred at any time that would affect the  preservation of the semen.
To ensure the temperature is an even as possible inside the container, the machine has a forced-ventilation system that guarantees constant recirculation of air.
The container’s interior is designed to enable the automatic collection and evaporation of condensates.

Description of the main parts of the machine

Installation and Operation

Controls and Indicators
As shown above, the container’s controls are located on the door. They include:

• A digital regulator, which enables the working temperature to be displayed and regulated at all times.
• An illuminated On/Off switch.
• A removable fuse-holder.

Placement
Site the Z-300 away from sources of strong heat or cold, and out of direct sunlight.
There should be sufficient space around the container to allow for good circulation of air behind the machine, as this is necessary to ensure adequate refrigeration of the condenser circuit.
To prevent vibrations and intrusive noise, make sure the machine is sitting perfectly flat on the floor or work surface.

Warning: Heavy machine; handle with care.

Connection to the Electricity Supply
The machine is fitted with a cable for connection to the power supply, located at the rear next to the compressor.

Important: Make sure the voltage of the electricity supply matches that indicated on the container’s specification plate. For the safety of the device and its operators, it is vital that it be earthed correctly in accordance with the Regulations for Low-Voltage  Electrical Equipment.

The manufacturer shall not be held liable for any claims in the event that these safety measures are not adopted. In the event of a power surge, short- circuit or excess consumption the Z300’s fuse will blow. It must be replaced with an equivalent item once you have identified and solved the problem.
To replace the fuse (the Z-300 is supplied with an instruction manual and replacement fuse), switch the machine off and unscrew the fuse-holder cap anticlockwise. Remove the sheath (with the fuse inside), replace the blown fuse with the new one, then insert the sheath back into the holder and screw the cap back on clockwise. A replacement fuse is included, along with the instruction manual.

Setting Up

1. Once the Z-100 has been installed in its place of operation, wait approximately 24 hours before switching it on. This will allow the oil in the compressor to settle and prevent contamination of the refrigerant fluid.
2. Connect the machine to the power supply.
3. Switch it on. The machine will then commence operations to reach its default working temperature of 16ºC. The ventilation system will start up and run constantly, alternating between refrigeration and heating cycles.

Viewing and Changing the Working Temperature.
The Z-100’s built-in digital regulator allows you to view the current temperature and modify the assigned temperature.

Once the machine is switched on, the regulator takes temperature measurements using the internal thermometer and displays these continuously on the screen.

The machine is programmed and calibrated at the factory to operate at a default temperature of 16ºC. However, if you wish to assign a different temperature, follow the steps below:

1. Press and release the key ‘SET’. The screen will show SP alternating the set point value.
2. Use the arrow keys to adjust the value.
3. Press and release ‘SET’ to confirm the value. The value will save in the memory of the device and the screen will show the current value of the temperature.

Once you have assigned the new temperature, the thermostat will begin to adjust the heating and cooling cycles as required. You can consult the status of the machine (i.e. whether it is heating, cooling or in neutral mode) by checking the corresponding LED  indicators displayed on the left side of the thermostat screen. The indicator for the cooling cycle is the snowflake and for the heating cycle is the sun indicator.

The thermostat is equipped with a buzzer that alerts the operator of any temperaturerelated anomalies, whether caused by a technical failure, leaving the door open, a power cut, etc.

–  If the temperature differs by more than 1,5ºC (in any direction) from the assigned temperature, and for longer than ten minutes, the buzzer will sound.
For example, if you have set the device to maintain a temperature of 16ºC, and the temperature either rises above 17,5ºC or falls below 14,5ºC for longer than ten minutes, the buzzer will sound.
If the buzzer sounds, it will be accompanied by the words “Hi” or “Lo” on the screen to indicate whether the temperature has risen too high or fallen too low.
Once the temperature returns to normal, the buzzer will stop automatically and the warning message will be removed from the screen. You can also turn off the buzzer at any moment by pressing any key.

Maintenance and Upkeep

Cleaning Advice
To clean the Z-300 it is recommended that you use a soft cloth and washing-up liquid.
Do not use strong detergents.
To completely disinfect the inside of the machine use 70-proof ethyl alcohol, taking care not to rub the adhesive stickers too forcefully.
If you are not going to use the machine for an extended period of time, keep it clean and dry and leave the door open, as this will help prevent mould forming.
Keep the grille at the back of the machine clean, as this will aid with heat evacuation (which is necessary to ensure the interior of the machine can be kept suitably cool).
Normally, at a working temperature of 16ºC excessive amounts of frost will not form on the machine’s cooling wall. Water droplets may appear, but these will be automatically expelled and evaporate outside the machine.
The power cable must be connected gently. Do not force it. The two metal poles in the connector must be kept clean in order to ensure good electrical contact.

Hazard warning: Before carrying out any form of authorisedmaintenance or procedure, make sure the area or parts in question arenot connected to the electricity supply. Unplug the device at the socket.

Further Information and Useful Advice
To ensure optimum preservation of the doses, follow these recommendations:

• Choose a container model that provides sufficient space for storing the quantity of doses produced under both normal conditions and during production peaks.
• Package the doses in separate bags or boxes before placing them in the container.
• Avoid overfilling one shelf when there are others that are empty. Distribute the doses inside the machine in such a way that the air can circulate freely.
• Always use the wire shelves that are supplied with the machine, as these allow the air to circulate without obstruction.
• Avoid placing the doses in direct contact with the cooling wall (the bottom of the container), as there is a risk they could become frozen.
• Do not position the doses very near to, or in direct contact with, the thermometer or the fan.
• Allow the doses to cool before placing them in the container: this will save energy and prolong the working life of the device.
• Open and close the door as little as possible.
