Venting the Vacuum Pump (Continued)
Venting from the pump may discharge either horizontally or
vertically; corrosion resistant pipe is recommended. Vent
lengths are allowed as follows:
LENGTH EP-200 PUMP EP-100 PUMP
up to 10'(3m) 4"(10cm) vent/no elbows -
up to 25'(7.5m) 5"(12.5cm) vent/3 elbows 4"(10cm) vent/3 elbows
up to 50'(15m) 6"(15cm) vent/3 elbows 5"(12.5cm) vent/3 elbows
If the vent pipe is over 30' (9 m) long, insulate it to
minimize condensation. Seal all discharge pipe joints with
General Electric RTV 106 or Permatex Form-A-Gasket
red high-temperature silicone adhesive or equivalent.
Pump Model EP-200 Installation (See pump manual
P/N 127200NA for assembly details.)
The layout drawing shows the general location of the
vacuum pump. Specific pump location and discharge
details must meet general venting requirements listed on
the previous page as well as the following criteria:
• To avoid staining building wall, extend discharge three
feet from building, if possible.
• Horizontal discharge (see Figure 21) is preferred.
Vertical discharge must be arranged as shown in
Figure 20.
A common practice is to mount the pump on the building
wall, using the mounting hardware furnished (see Figure
22). If this is not practical, it may be mounted on a
platform suspended from the ceiling, or for noise
reduction, in an enclosure.
Pump Model EP-100 Installation (See pump manual
P/N 127201NA for assembly details.)
The Model EP-100 is mounted the same way as the EP-
200 (see above directions). Optionally, the pump may be
suspended from chains (see Figure 22). This installation
method requires 3 lengths of chain and 3 S-Hooks (not
supplied).
Installation Precautions
The pump scroll attaches to the pump frame (see Figure
22) with either right- or left-hand discharge as the job
requires. Please note that the motor must be wired
differently depending on discharge direction. The
discharge must be bottom horizontal. Any other
arrangement will permit condensate to collect in the
scroll.
