Turnina The Aspirator On
The center position of the switch on the electrical panel is OFF. Placing switch in the UP position
bypasses the foot pedal and turns the aspirator on manually. To use the Pneumatic foot pedal, place the
switch in the DOWN position. The foot pedal is a "Push On
*
For best results using the foot pedal, press quickly and firmly.
*
The pilot light is illuminated when the aspirator is on.

In the event of electrical overload there is a circuit breaker on the electrical panel that
can be manually reset.
SP-320 Pump Module
The pump module is of a two stage rotary, oil type construction. This
type was chosen due to it's durability, low noise factor and it's
capability of producing vapor pressure vacuum. During high vacuum
procedures vaporization of moisture will occur. This vapor will pass
through the system (including the intake filter) and is collected by the oil.
*
You must service module every TEN HOURS OF OPERATION to
remove this moisture.
Service Pump Module

Hint: Module should be cool and allowed to stand 24 hours or
more after last use. The water and oil will separate and water will
collect on the bottom of the pump.

Removing pump from chassis: Unplug from electrical panel,
remove the two hoses, and lift straight up
(the pump sits on springs and is not fastened).

The top section of the housing threads onto the
bottom section of the housing, simply unscrew the
top from the bottom, remove the filter, clean the
inside of the housing, and replace with a new filter.

NOTE-Make sure the "0-Ring" in the lid of the
housing is in its grove. Lubricate the 0-Ring with

*
The INTAKE filter should be replaced about once a year. You must
change the filter in the event of an overflow, or
if
there has been contamination.
*Also available is a see through, clear exhaust filter housing (PIN:
EFH-S5CL) to replace the
old style blue filter housing, this allows for a quick visual check of the filter to see if it needs replacing.
Check Valve
The function of the check valve is to prevent back flow
from the pump into the intake filter. Should your unit not'have
a Check Valveinstalled, simply cut the tubing 1 112 to two
inches from the module intake fitting and insert
!la
check valve. See diagram (Note direction of arrow).
Additional Notes
*
It is normal for a pump to have a sluggish start, after a period of
non use of a week or more.
*
It is always good practice to start the aspirator
prior to surgery.
*
The best assurance is to have a spare pump avail-
able.
The stand by pump should always be stored with
(DO
NOT
DISCARD)
fresh oil.
*
When installing pump, make sure the switch on
the motor is in the "ON" position. Use this switch
when servicing the pump outside the chassis with
an extension cord.
*You can trace a leak by removing the gauge from
the small bottle and plugging it directly into the
hose from the pump, and tracing it back one
component at a time.

of the chassis with the electrical panel, then snap the clasps into place.
*Place green lid on top of small bottle, set the jar in the small holder, so that the two stainless
steel hose connections face towards the canister bracket. Use the 'small' strap to fasten the
jar to the chassis.
