  • Page 31: Set-Up

    SYSTEM Set up the PRC 2000 system using Figures 15 through 18 and the following steps. 1. Store the shipping container(s) in a convenient location. Reuse of these containers will prevent damage if you ship or store the system. 2. Place POWER Switch in the “OFF” or “0” position.
  • Page 32 Turn Locking Ring fully clockwise to lock in place. Figure 17. TMC Handpiece Connection 10. To avoid confusion among handpieces, PACE recommends the use of colored markers (P/N 6993- 0136 Cable Marker Kit) to identify the particular handpiece power cord and/or air hose. Attach any two like colored markers, one to each end of the handpiece power cord or air hose.

  • Page 33: Handpiece Vacuum/Pressure

    HANDPIECE VACUUM/PRESSURE The SX-65A, SX-70 and TP-65 handpieces require the use of the SNAP-VAC (vacuum) Port and the TJ-70 handpiece requires the use of the Controllable PRESSURE Port on the THERMAL MANAGEMENT CENTER (TMC). There are two preferred methods for connection of the Air Hose. The advantages of each method are discussed in the paragraph below.
