IMPERIAL TRUCK MOUNTED VACUUM TANKER MANUAL
★
IMPORTANT: Clean the fi nal fi lter regularly.
An excess buildup of lint in the fi nal fi lter can
reduce airfl ow in the vacuum system, reducing
performance of the vacuum pump. Also, reduced
airflow through the vacuum pump can result
in overheating, leading to eventual pump
damage.
Primary Shutoff
Inspect the primary shutoff every 2 weeks to
check the rubber ball seat and the tightness of all
fasteners.
Your vacuum tanker is equipped with one of two
styles of primary shutoff, depending on which type
of air-line system the tank has.
To inspect the ball seat on external air-line systems
(Figure 4.), begin by removing the primary shutoff
access lid.
Next, remove the fl oat cage to gain access the ball
seat. Examine the ball seat for hardened rubber,
nicks in the rubber, and a buildup of debris. Any of
these conditions may prevent proper sealing. Clean
or replace the ball seat as necessary. Reassemble in
the reverse order; furthermore, be sure to tighten all
fasteners adequately.

Final Filter
Clean the fi nal fi lter as often as every day, depending
upon the lint content of the material being pumped.
For example, lint is more of a problem when pumping
holding tanks than when pumping septic tanks,
where the paper fi bers in the effl uent decompose.
When cleaning the fi nal fi lter, provide yourself with
gloves, eye protection, and protective clothing and
then use the following procedure:
1. Loosen the wing nuts and remove the cover.
2. Remove the nut on top of the fi lter and remove
the canister.
. Clean the lint from the fi lter screen. If necessary,
swirl the fi lter in a pan of soapy water to loosen
the lint.
4. Reassemble in the reverse order.
WARNING: Wear protective gloves, eye
protection and appropriate clothing when
cleaning the fi nal fi lter. Being a component of the
vacuum system, the fi lter is subject to exposure
by sewage effl uent or septage. These materials
may contain hazardous chemicals and bacteria,
which can cause infection, injury, or even death
due to contact.
