HLV Series 3.0 Installation • Tube Assembly and Mounting • Hanger Placement
Tube Assembly and Mounting
Tube installation begins at the vacuum pump:
1 If installing a condensing system, slope condensing pipe upward from the vacuum pump 1/4 in.
per 10 ft. as shown in Figure 3.5. Non-condensing systems are mounted level.
Figure 3.5 • Condensing Pipe Suspension
2 It is critical that tube mounting begins with the run having the greatest amount of condensing
pipe. If installing a non-condensing system, begin with the longest run.
NOTE: Baffle installation must be as close to the vacuum pump as possible and in the section of
tubing that allows insertion of the entire length of baffle (refer to page 27 for baffle assembly and
placement instructions).
3 Space two wire hangers approximately 8 ft. to 9 ft. apart to mount the first tube section. Only one
hanger is required for every tube thereafter, spaced approximately 9’-8” apart. Place tubes in
hangers with welded seam facing downward and the swaged end of the tube towards the vacuum
pump (Figure 3.6).

as it approaches the vacuum pump.
Turnbuckles (P/N: V-TB)
are recommended for all
condensing pipe suspension
points for ease of slope
adjustment.
