General safety For your own safety, when carrying out work on this product, all relevant national safety regulations must be complied with relating to pressurized and electrical systems. 2.1. Intended use of the Product The dryer is exclusively intended for the treatment of compressed air, which is free from bulk water, oil and solid matter constituents.
(35°C). • For dryer performance at other inlet conditions or -100°F (-70°C) dewpoint requirements, contact TOPRING. • All dryers should be proceeded by a coalescing filter regardless of oil or oil free applications, a 0.01mg/m3 grade coalescing filter must be installed on the inlet to the...

System Layout 8.1. Typical installation 54.316 – 54.322 8.2. Typical installation 54.324 – 54.330 IMPORTANT: It is essential that the system into which the dryer is installed is fitted with a pressure limiting/relief device. This device should be between the compressor and the dryer. The device must be set to prevent the maximum working pressure of 232 psig (16 barg) from being exceeded.

8.3. Site Location When selecting an installation site for the dryer, ensure the following conditions are met: • Installation site should be located indoors on a flat surface protected from the weather and other harmful conditions. • The ambient temperature must not drop below 33.8°F (+1°C) or exceed 122°F (50°C).
Electrical Installation 9.1 Mains Power Connection To install the mains power cable: 1. Remove the two screws from the top cover and lift from the dryer. 2. Locate the two latches at the top and bottom of the shroud and pull them towards each other to open the shroud to expose the controller (See Fig 1.) 3.

9.2 Remote Stop/Start Control (if required) To gain access to the remote start/stop feature: • Remove the two M5 screws from the top cover and lift away from the dryer. • Locate the two latches on the top and bottom manifold and pull in the oposite direction to each other to open the shroud, this will then expose the controller.
10. Dryer Operation Locate the electrical connector on the underside of the controller in the shroud. (see 15. PID page 22 & 23.) 10.1. Dryer Start-up Do not allow the dryer to flow air unless switched on and cycling. Resulting effect could be desiccant contamination;...

10.3. Monitoring dryer performance Energy saving option (If installed model numbers have B in place of A at 7th digit) • The dew-point is displayed on the control panel. When the pressure dew-point displayed is better than -42°C PDP the dryer will switch into economy mode and stop cycling, resulting in zero purge, but no interruption in flow.
• Do not modify or adjust the control settings. • Only certified TOPRING. Approved replacement parts should be used. • Always check all connections for leakage and secure seating. • Ensure all loose parts are removed or secured to the dryer before operation.

12. Servicing Maintenance operations should only be carried out by authorized, competent and suitably trained personnel. 12.1. Servicing Guidelines • Maintenance operations only to be conducted when the system has been shut down, fully depressurized and isolated completely from the compressed air and electrical supply.

12.2. Service Procedures A dryer service should take place every 2 years or 12,000 hours of operation (whichever occurs first). Service kits are available which include: replacement desiccant cartridges, seals and valves. Please contact the manufacturer or distributor for service kit information. •...
13. Troubleshooting Problem Problem Caused Solution Insufficient inlet pressure Inlet pressure min 58 psig (4 barg). If not adjust inlet pressure settings. Electrical Fault Ensure the power is on and the dryer front panel is illuminated; check the dryer is cycling correctly. Moist or contaminated Eliminate the cause of contamination.
