Maintaining the PCS2 Equipment

P/N 85266-30, Manual revision: A
Pressure
monitors
The pressure monitors (DPM/SPM) should be cleaned daily in the following
manner:
Î
Depress and hold the white ring as if installing the disposable filter.
Î
Wipe the silver rod thoroughly, using a circular motion and warm water.
Î
Dry the rod and release the pressure on the ring.
Caution:
It is very important to use
only
water on the pressure monitor rod.
Alcohol or cleaning solution residue could cause a reaction with the plastic ma-
terial of the corresponding disposable set filter and affect the function of the filter.
Air detectors
The DLAD1, DLAD2, and BLAD are designed with a groove to hold the dispos-
able tubing. The contents of the tubing are monitored by the sensors which are
located internally on either side of this groove. If a procedure is interrupted due
to an air detector alarm, the operator should remove the tubing and clean the
groove before continuing the collection procedure.
The operator should use
only
warm water and lint-free gauze to clean and dry
inside of the tubing grove. The groove should be kept free of any particles, such
as powder residue from disposable gloves, since this could lead to an erroneous
detection of air.
Caution:
Alcohol may cause the plastic housing to degrade and must not be used
to clean the air detectors.
Optical sensors
The lenses of the optical sensors must be kept completely free of particles or
debris which could produce inaccurate readings and influence the PCS2 device
performance. The operator should use
only
water and lint-free gauze to clean and
dry the lenses.
Caution:
If cleaning solution should come into contact with the optical sensor
lenses, the lenses should be cleaned immediately with lint-free gauze and warm
water, then thoroughly dried. Dried cleaning solution can leave an opaque film
on the lens.
Line sensor
The line sensor, located on the PCS2 top deck, contains two very small lenses
which are centered on either side of the disposable tubing groove. The operator
should carefully pass the gauze through this groove to clean and dry the lenses.
Optical bowl sensor
The optical bowl sensor lens is located in the upper portion of the centrifuge well.
The operator should ensure that no spots remain on the lens cover after it has
been cleaned and dried.
