Use a suitable valve to isolate the pump from the vacuum
application. This is to allow the pump to warm up before
pumping condensable vapors and to clean the pump after
use before it is switched off.
When assembling, ensure
vacuum-tightness
. After as-
sembly, check the whole system for leaks.
Secure hose connections at the pump appropriately, e.g.,
with hose clamps, to protect against accidental detach-
ment.
To reduce pump noise emanating from the pump exhaust
port, connect an exhaust hose or use a silencer (see ”Ac-
Separator (inlet) and
exhaust waste vapor condenser (outlet)
Assembling the hose nozzle with union nut:
➨
Take the hose nozzle with attached compression fer-
rule and union nut out of the catchpot and put onto in-
let connection (version 2 AK: onto inlet and outlet con-
nections).
➨
Tighten the union nut by hand until you can feel the
stop. Then tighten an additional 1/4 rotation with an
open-ended wrench (size 17mm) for final installation.
Catchpots:
The catchpot at the inlet protects against drop-
lets and particles from entering the pump.
+
Enhances lifetimes of diaphragms and
valves.
+
Improves vacuum performance in applica-
tions with condensable vapors.
Both catchpots are coated with a protective
layer to protect against shattering in case of
breakage or implosion.
➨
Assemble the catchpots at the inlet and at
the outlet using joint clips.
