Nut (2) 4.3 SERVICE AIR PIPING PIPE SIZING Before installing the compressor, review the service air system’s layout including: pipe sizes, auxiliary separator tube, drip legs, line filter(s), and isolation valves (See Figure 4-3). Pipes should be sized as a minimum to match the dimensions of the compressor’s discharge connection.
SHOPTEK™ USER MANUAL SECTION 4 ISOLATION VALVES FLUID CONTAINMENT Install isolation valves where isolation of the compressor from the service lines is required. These valves should have drip legs that drain at an angle downward from the base. A vent to the piping should be installed downstream of the compressor outlet connection. Compressors have a fluid containment pan to collect fluid leaks or spills. The pan has a drain located on the front side of the machine.
SECTION 4 SHOPTEK™ USER MANUAL during compressor operation. Check the fluid level by looking at the sight glass on the separator tube when the compressor is in the SHUT DOWN MODE (fluid level may not be visible when operating). In this condition the sight glass should be completely full. Add fluid if the level is visible or if no fluid is visible at all. 4.6 ELECTRICAL PREPARATION Interior electrical wiring is installed at the factory.

SHOPTEK™ USER MANUAL Section 5 OPERATION 5.1 ROUTINE OPERATION Before starting the compressor, check the fluid level in the separator tube. If sight glass is not completely full, add the required amount of fluid to bring it to its proper level. Frequent addition of fluid indicates the presence of a leak or a condition causing excessive fluid consumption. See the Troubleshooting – Introduction on page 66 under EXCESSIVE COMPRESSOR FLUID CONSUMPTION for a probable cause and corrective action.
