Field wiring to the tube heater must be connected and grounded in accordance with national,
state, provincial, local codes and to the guidelines in the Tube Heater General Manual and
Series Insert Manual. In the United States refer to the most current revisions to the ANSI/NFPA
70 Standard and in Canada refer to the most current revisions to the CSA C22.1 Part I Standard.
• An HLV Series vacuum system operates on 120V, 60 Hz. If an alternate voltage will be used, consult
the factory.
• The HLV Series vacuum system is designed to operate as a two-stage system unless it has been
factory configured to operate as a single-stage system (P/N: V-1SAO). Reference the appropriate field
and internal wiring diagrams (Figures 3.21-3.25) for the system being installed.
• Amperage draws for individual system components are indicated in Chart 3.4.
• The circuit(s) must be sufficient to handle the starting amperage of all burner control boxes and the
running amperage of the vacuum pump.
• Wiring from the power supply to the pump and control panel assembly must be 12 AWG or larger to
maintain proper voltage under full load conditions.
• The circuitry for the pre-wired pump and control panel assembly is suitable for up to a 20 amp circuit
maximum.
• Confirm the control panel assembly remains as wired from factory for proper fan rotation. Check
directional arrow on pump housing for proper wheel rotation (excludes NC-7 Series pump).
NOTE: Each vacuum pump is equipped with one control panel which is factory wired for up to two
temperature zones (Figure 3.25, p.38).
