2 OPEN-DRIVE COMPRESSORS These compressors are desi gned to operate with Refriger- ants 12, 22, 134a, 502, or 507/404A. See T able 1. Operating Requireme nts — Satis factory op eration of a reciprocatin g compres sor depen ds on 3 fundamental requiremen ts: 1.
3 During compressor shutdown, gr avity , thermal act ion and refrigerant absorption can result in a re frigerant and oil mixture in compressor crankcase. Gr avity flow can be preve nted by the use of recommende d loops, but therm al action a nd t he absorp- tion of refrigerant by lubricating oil cannot be prevented by piping design.
4 Compressor Capacity Notes 1. Compressor capacities are based on 1750 rpm and 15 F subcooling for all unit sizes and refrigera nts. 2. Multiplying factors for other rpm: See Multiplying Factors chart on pa ge 31.

23 Control Pressurestats — Dual pressurestats are furnis hed with all 5F ,H compress ors. They ar e often referre d to as high- and low-pressure cutouts. Their function is to cut the ci rcuit to the holding coil of the compressor motor start er when pressure setting l imits a re exceede d.

25 CAP ACITY CONTROL MODIFICA TIONS F OR HEA T PU M P A PP L I CA T ION — Where 5F40, 5F60, and 5H com- pressors are used in refrigerant cycle r eversing heat pump applications, it is usually necessary to modi fy the standard capacity control arrangement to satisfy unloading requir e- ments.
26 Appli cation Requi ring 50 % Capacit y Reduct ions — This is the usual specification f or heat pump applications and should cover majority of cases.
27 The variety of systems using 5F ,H c ompressors make it impractical to cover all a spects of hot gas bypass operation. The following guidelines will aid in determining the proper application. The hot gas bypass valve is basically a press ure regulating valve installed to hold a constant compressor suct ion pressure.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Carrier 09RH è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Carrier 09RH - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Carrier 09RH imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Carrier 09RH ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Carrier 09RH, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Carrier 09RH.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Carrier 09RH. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Carrier 09RH insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
