Un buon manuale d’uso

Le regole impongono al rivenditore l'obbligo di fornire all'acquirente, insieme alle merci, il manuale d’uso Sea Frost DC 5000. La mancanza del manuale d’uso o le informazioni errate fornite al consumatore sono la base di una denuncia in caso di inosservanza del dispositivo con il contratto. Secondo la legge, l’inclusione del manuale d’uso in una forma diversa da quella cartacea è permessa, che viene spesso utilizzato recentemente, includendo una forma grafica o elettronica Sea Frost DC 5000 o video didattici per gli utenti. La condizione è il suo carattere leggibile e comprensibile.

Che cosa è il manuale d’uso?

La parola deriva dal latino "instructio", cioè organizzare. Così, il manuale d’uso Sea Frost DC 5000 descrive le fasi del procedimento. Lo scopo del manuale d’uso è istruire, facilitare lo avviamento, l'uso di attrezzature o l’esecuzione di determinate azioni. Il manuale è una raccolta di informazioni sull'oggetto/servizio, un suggerimento.

Purtroppo, pochi utenti prendono il tempo di leggere il manuale d’uso, e un buono manuale non solo permette di conoscere una serie di funzionalità aggiuntive del dispositivo acquistato, ma anche evitare la maggioranza dei guasti.

Quindi cosa dovrebbe contenere il manuale perfetto?

Innanzitutto, il manuale d’uso Sea Frost DC 5000 dovrebbe contenere:
- informazioni sui dati tecnici del dispositivo Sea Frost DC 5000
- nome del fabbricante e anno di fabbricazione Sea Frost DC 5000
- istruzioni per l'uso, la regolazione e la manutenzione delle attrezzature Sea Frost DC 5000
- segnaletica di sicurezza e certificati che confermano la conformità con le norme pertinenti

Perché non leggiamo i manuali d’uso?

Generalmente questo è dovuto alla mancanza di tempo e certezza per quanto riguarda la funzionalità specifica delle attrezzature acquistate. Purtroppo, la connessione e l’avvio Sea Frost DC 5000 non sono sufficienti. Questo manuale contiene una serie di linee guida per funzionalità specifiche, la sicurezza, metodi di manutenzione (anche i mezzi che dovrebbero essere usati), eventuali difetti Sea Frost DC 5000 e modi per risolvere i problemi più comuni durante l'uso. Infine, il manuale contiene le coordinate del servizio Sea Frost in assenza dell'efficacia delle soluzioni proposte. Attualmente, i manuali d’uso sotto forma di animazioni interessanti e video didattici che sono migliori che la brochure suscitano un interesse considerevole. Questo tipo di manuale permette all'utente di visualizzare tutto il video didattico senza saltare le specifiche e complicate descrizioni tecniche Sea Frost DC 5000, come nel caso della versione cartacea.

Perché leggere il manuale d’uso?

Prima di tutto, contiene la risposta sulla struttura, le possibilità del dispositivo Sea Frost DC 5000, l'uso di vari accessori ed una serie di informazioni per sfruttare totalmente tutte le caratteristiche e servizi.

Dopo l'acquisto di successo di attrezzature/dispositivo, prendere un momento per familiarizzare con tutte le parti del manuale d'uso Sea Frost DC 5000. Attualmente, sono preparati con cura e tradotti per essere comprensibili non solo per gli utenti, ma per svolgere la loro funzione di base di informazioni e di aiuto.

    5 GENERAL DESCRIPTION The SEA FROST DC 5000 is a cold storage refrigeration system powered by a 1/2 horsepower permanent magnet direct current 12-volt motor. Refrigerant from the compressor is piped to the SEA FROST plate in the icebox. Cold storage is attained by rapidly freezing the solution contained in t he plate, creating a c aptive (replenish[...]

  • Pagina 6

    6 After about one hour (with a single plate), the plate will become very cold. Starting from warm will require more running than the normal refreezing time of the plate in its usable temperature range. The concept of the SEA FROST system is to create as much frozen material in the plate as fast as possible. This "coldness" then keeps the [...]

    7 ICE MAKING WITH VERTICAL TRAYS ON VERTICAL PLATE SYSTEMS Fill the vertical trays with water and hang them on the stainless steel rod on the face of the plate. Try to get some water between t he tray and the plate surface to increase the thermal contact to speed freezing. The trays may take time to freeze after the plate is frozen and the compress[...]

    8 CLEANING The plate surface protects itself with a layer of oxidation. You might find after a long period of storage the plate will look chalky. This will not effect operation and is easily cleaned up with a pot scrubber and soap. HOW REFRIGERATION WORKS There are two important conc epts to understand in order to learn about refrigeration. They ar[...]

    9 By causing R-134a to boil (evaporate) in the SEA FROST plate, we use the heat energy there. This activity cools the liquid solution within the plate, causing it to change phase (freezing to a solid). By freezing this solution, we have increased its heat absorption capacity more than 100 times. When the cycle is stopped (the compressor is turned o[...]
