Who handles claims in Poland

Frostbox is the exclusive representative of MTH S.r.l. in Poland and the authorised service centre for the Polish market — sales, service, spare parts and commercial representation, based in Wrocław. All warranty, service and complaint claims on Polish territory are received by Frostbox; the manual is explicit that customers should nie powinien contact the manufacturer directly.

• E-mail: [email protected]
• Telefon: +48 71 707 90 25

A claim sent to [email protected] is registered and handled in order of receipt, so sending it in writing puts it in the queue with a date on it.

What you must be able to produce

To exercise a warranty right, the buyer has to present the seller with all four of the following:

1. The warranty certificate. One is issued for every product delivered and accompanies the manual.
2. A document confirming the delivery date — either the invoice or the delivery note (transport document). One of the two is enough; neither is optional.
3. The appliance together with every electrical cable and accessory supplied with it. These accessories must be in undamaged condition — damaged or missing accessories are themselves grounds for losing the warranty.
4. The appliance with the MTH tamper-proof seals intact.

Missing paperwork: if neither of the two delivery-date documents — the invoice or the delivery note — can be produced, the validity of the warranty cannot be confirmed. The intervention is then treated as chargeable to the buyer and invoiced. Keep the purchase documentation with the proof of sale from day one and store it where a service technician can be shown it.

Documentation for an Algor room is not shipped on paper. The warranty certificate, the CE declaration of conformity, the refrigeration unit manual, the wiring diagrams, the assembly drawing and the packing list arrive as attachments to an email from Frostbox, together with the download links given in it. If you cannot find them, ask for a re-send at [email protected] quoting the product code oraz invoice number.

The fourteen circumstances that void the warranty

Dowolny one of the following is enough to extinguish the right to warranty cover. Once that happens, work carried out by MTH technicians or by anyone MTH has authorised is invoiced to you:

Tampering and unauthorised work

• Breaking the tamper-proof seals applied by MTH S.r.l.
• Any dismantling, modification or interference with the appliance or its components carried out by the user or by unauthorised personnel.
• Fitting spare parts that are not original or not indicated by MTH S.r.l.

Installation, supply and earthing

• Installing the appliance in conditions other than those given in the manual.
• Connecting it to an electrical and/or hydraulic installation of insufficient capacity, or one that does not comply with the regulations in force — the manual calls out earthing rules and good engineering practice in particular.

Transport and force majeure

• Damage caused by force majeure or arising in transport. Delivery is made EXW (Incoterms ICC), so responsibility for transport damage lies with the carrier and must be reported directly to the carrier at the moment of receipt. Damage resulting from faulty installation or faulty maintenance is likewise not accepted as valid grounds for a warranty claim.

External events and accidents

• Failure to operate caused by a power cut, mains voltage fluctuation or a similar event, and any faults arising from it.
• Faults caused by accidental damage — the manual gives a disconnected plug and blown fuses as examples, without limiting the list — and other problems traceable to external factors or to the buyer's negligence.

How the room is used and maintained

• Use contrary to the regulations in force in the country of operation.
• Using the appliance for a purpose other than the one it was prepared for.
• Using it in a manner inconsistent with the operating and maintenance manual.
• Total or partial failure to follow the manual's instructions.
• Absence of maintenance, or maintenance carried out incorrectly.

Controller settings

• Changing the setting parameters of the supplied controller.

Controller note: the buyer or user may change only two parameters — the temperature setpoint oraz defrost interval (IdF). Every other parameter on the supplied controller is off limits, and altering one is listed as grounds for loss of warranty. If a room will not hold temperature, the fix is a service claim, not a deeper dive into the controller menu.

The warranty period itself and the full conditions are not summarised here: they are set out in the warranty certificate supplied with your room and in the "Warranty conditions" chapter of the manual, whose point 5 is the source of the list above.

What to include when you file a claim

Send the following in one message so the claim can be assessed without a second round of questions:

• Product code and production date, both read from the data plate.
• Invoice number or delivery-note number.
• Temperature readings from your record card, if the fault is a temperature one.
• A description of the fault — what happens, and since when.
• Photographs of the cold room and of the controller.

The same identification data from the data plates is what you quote when ordering spare parts or asking a usage or maintenance question. Because non-original parts void the warranty, sourcing parts through the authorised service centre is not just convenience — it is what keeps the cover alive.
