Frequently Asked Questions - 321216 Mach

How do I install the rotisserie?

Place the unit on a flat, sturdy surface at least 15 cm from walls. Keep flammable objects away. For models with a stove, place on floor and adjust legs. Remove plastic coating before first use. Ensure electrical supply is 230V 50Hz and well earthed. All electrical work must be done by a qualified electrician.

How do I connect the power?

Connection must be carried out by a qualified electrician. The unit can be wired with 1, 2, or 3 lines plus neutral (L+N, 2L+N, 3L+N). Use appropriate wire sizes and fuses as per the table in the manual. Each line must have its own fuse and switch with contact separation at least 3 mm.

How do I load the spits?

Place three chickens on the spit, then fix the middle hook. Add the remaining three chickens, fix the outer hook, and tighten the wing screw. To install the spit, first insert the left end into the bearing, then hook the right end into the holder. Ensure the spit's groove aligns with the holder's pin for secure positioning.

How do I load the baskets?

Put up to 4 chickens per basket, ensuring the hook goes inside the chicken. Distribute chickens evenly across baskets for balanced rotation. To install, hang one basket hook on a bolt, then the other. Use the motor switch to rotate the axle to the next loading position. T16, T24, T36 also have a single bar spit for specialties.

How do I set the thermostat and timer?

Press the L1 button to display temperature. Use L2 to increase, L1 to decrease. For timer, press >> to increase or << to decrease duration. Press start to begin a timed cycle. For continuous operation, press and hold the button for 3 seconds. The display returns to default after a few seconds of inactivity.

What should I do if the glass cracks?

Prevent cracking by never washing or touching glass with a wet cloth while it is hot. If glass breaks, disconnect power immediately and replace the glass with a genuine part. Only clean glass when absolutely cold, using glass cleaner or warm soapy water, and dry thoroughly before reuse.

How do I clean the unit?

After each use, drain the grease trough, remove spits/baskets, and wash with warm water and dishwashing liquid. Once cool, wipe interior with a damp sponge. Clean glass with glass cleaner or soapy water only when cold. Weekly, disconnect power and wipe external surfaces with a lightly damp cloth. Never wash the appliance directly.

Why is there smoke during grilling?

Smoke is usually caused by grease burning on the heating elements or trough. To prevent this, fill the sliding grease trough with 2–3 cm of water before grilling. The water catches falling grease, reducing smoke and improving meat flavor. Also ensure the trough is not overloaded with grease.

Can I grill other meats besides chicken?

Yes, the rotisserie can be used for other meats. For spit models, use the single bar spit for specialties like pork or lamb. For basket models, you can grill items suitable for basket grilling. Adjust cooking time and temperature according to the meat type.

What are the main safety precautions?

Ensure the unit is properly earthed and connected via its own fuse. Do not expose to water. Keep flammable objects at least 15 cm away. Never operate with wet hands. Only qualified electricians should perform wiring. Always disconnect power before cleaning. Do not wash the appliance to avoid electric shock.

The T16, T24 and T36 are equipped also with a spit (single bar) that you can use to grill your specialties. In the sketch above you can see how to fix it on the disc.

5.4 GRILLING

Pull the sliding grease trough and put in it as much water as is necessary to be covered in a depth of 2 – 3 cm.

This way the grease which falls from the meat, when the grilling starts, does not make smoke in the grilling room and the meat gets better taste.

Close the doors and supply full power to all heaters.

Press the switches controlling the spit rotating motor.

The grilling starts.

Inspect the grilling proceeding and if necessary decrease the heat by switching off the heaters.

If you own the S3, S5 or S9 you can store the grilled meat in the warming room which is in the lower part of the unit, and load it again to grill a second batch of chicken.

Always after serving part of the grilled chicken before you start the spits or baskets rotation again be sure that they are well secured in their hangers.

Always, before you start grilling, be sure that the sliding grease trough is covered with water in a depth of 2 – 3 cm and that is not full of grease that could overflow.

6. MAINTENANCE

Every when you finish grilling switch off the heaters and drain the grease from the grease collecting trough.

Remove the spits or the baskets and wash them with warm water and dishwashing liquid.

After the unit becomes cold disconnect it from mains by turning off the corresponding switch in your installation, and clean with a wet sponge the inner surfaces.

When the unit becomes absolutely cold, clean all the glass surfaces with glass cleaning liquid or warm water and dishwashing liquid.

Be sure that the glasses are absolutely dry before you put the unit in operation again.

Never wash the glasses and never touch them with something wet when they are warm. This could cause their breaking

Remove the grease collecting trough and wash it with warm water and dishwashing liquid.

Dry all parts you've washed before you put them back to their place and leave the unit 10-15 minutes to become dry before you plug it again to mains.

Once a week disconnect the unit from mains and clean with a lightly wet clothe the external surfaces. Leave it 10 – 15 minutes to become absolutely dry before you plug it again to mains and put it in operation.

Never wash the appliance. This could expose the user to electric shock's hazard.

Once a week inspect the cables connecting it to the mains and be sure that they are always in good condition.
