I believe this is a re-badged Hankinson dryer, as many compressor company branded dryers are. It should be a good unit. Make sure it is rated for the maximum flow you will be putting through it or you will be wasting your time. It should be installed after the air tank and before any air consuming devices. Make sure it has adequate ventilation to shed it's heat, and keep the condenser free of debris. More than one customer was amazed when I fixed their broken dryer by bowing the **** out of the coils and restating the dryer. It should be plugged in at all times, since many dryers have a crankcase heater to keep the refrigeration lubricant from gelling. It usually requires plugging in for 24hrs before putting it into service. Like any refrigeration device, it takes time to get the working surfaces down to operating temperature, so don,'t expect to just throw the switch a few minutes before you start your compressor. You really should get the manual for a definitive guide to operating it. The air entering it shouldn't be above 100F, otherwise it might not be able to cool the air enough to be effective. A good filter before the dryer will help keep the heat exchanging surface inside free of oil and scale. You will also need a place to drain off the condensate.
