components do not come in contact with
the
breathing gas; consequently, they require cleaning with only a damp cloth. This includes the
entire control unit as well as certain bellows assembly components. Only the bellows base
interior and the inside of the bellows come in contact with the breathing system gases.
CAUTION:
NEVER use an abrasive cleaner to clean any part of the ventilator. Abrasives will scratch the
transparent acrylic bellow housing and other surfaces of the ventilator. Also, DO NOT allow
water from an overly-damp cloth to collect on or penetrate into the ventilator.
Cleaning the Ventilator Surfaces:
The outer surface of the ventilator may be cleaned simply by
using a clean, soft, slightly damp cloth. A mild detergent solution may be used to remove
persistent surface dirt or grime. Be sure to use only a mild detergent, if necessary, and use care to
ensure that the cloth is only slightly damp.
WARNING
:
Clean bellows and bellows housing only with water and a mild detergent. Use a soft cloth.
Avoid abrasives and aromatic spirits. (USE NO ALCOHOL.)
Cleaning the Bellows Housing:
Remove the bellows housing for cleaning and for access to the
bellows and pop-off valve. Twist the housing counterclockwise until the tabs at the base of the
housing clear the bayonet locks. (This may require some degree of force because of a tight o-ring
fit.) Tilt the top of the bellows housing toward you and lift it off. DO NOT attempt to steam-
sterilize the bellows housing. Since it does not come in contact with the breathing gas, it needs
only occasional cleaning with a clean, soft slightly damp cloth, or by immersion in a mild
detergent bath, followed by rinsing. Moreover, steam sterilization may warp or deform the
housing rendering it useless. USE NO ALCOHOL.
Cleaning the pop-off valve:
With the bellows housing removed, it is necessary to also remove
the bellows to gain access to the pop-off valve. This is easily accomplished by gently pulling the
bellows to the side until it detaches from the base.
Removing the bellows exposes the pop-off valve and the three small red thumbscrews which
attach it to bellows base. Loosen the three screws and remove the valve. The black, ULTEM
pop-off valve seat will now be exposed. This valve seat has a precision machined and lapped
surface, which is relatively delicate: USE CONSIDERABLE CARE while cleaning the seat with
a clean, soft, damp-cloth. Clean P.O.V. disk with cotton swab and alcohol.
CAUTION:
NEVER use an abrasive cleaner or hard object to clean the valve seat. Abrasives or hard objects
will scratch or damage the seat, causing the pop-off valve to leak, which will result in a serious
malfunction of the ventilator.
NOTE THAT EVEN A PIECE OF LINT ON THE SEAT COULD CAUSE A LEAK.
After cleaning the pop-off valve seat, replace the valve taking care to ensure that the small orange
o-ring (PN 180A1429) under the pop-off valve is securely in place. If this orange o-ring is
dislodged or missing, the ventilator will not be able to function properly.
