5.2 Ultrasonically clean deposits from all metal parts
Clean deposits from all metal
parts, like chalk and salt.
WARNING:
Do NOT use aggressive chemicals. They might damage the metal plating.
Use an ultrasonic cleaning bath with a suitable cleaning fluid instead. A good cleaning fluid is
Biox “O2” immersion fluid. See WWW.BIOXINT.COM for further information and distributors.
The use of rubber gloves while re-assembling the APV200 is highly recommended to avoid
rendering the APV200 unclean due to human touch.
For photographic clarity no rubber gloves are worn on the photos in this manual.
5.3 Replace all O-rings with new ones from the Service Kit
WARNING:
- Replace all O-rings: do NOT re-use old ones.
- ONLY use original parts from APD, to make sure the O-rings:
o
Are the exact size;
o
Are of the correct material (especially important in a high oxygen content and
overpressure environment);
o
Are of the correct stiffness (degrees Shore).
5.4 How to lightly grease O-rings
When greasing O-rings, make sure NOT to use too much grease.
Especially O2 compatible grease has the potential to become stiffer over time, which may
cause a hardened clot of grease to become a source for leaking.
The best way to grease O-rings is using a simple “grease bag”.
A grease bag is a clean and clear plastic bag, into which you put a small amount of grease.
Optionally you can make two bags: one with O2 compatible grease, and one with normal
silicone grease. Make sure you label them properly to avoid mixing them up! Also put a date
on it, so you know how old your grease bag is. Don’t use them longer than a year.
A nice advantage of using a grease bag is that you use only a tiny amount of grease for
greasing many O-rings, so there is little waste.
We recommend that you use resealable bags, e.g. the ones with a plastic zipper, typically
used for airtight food storage. This allows you to zip up the bag after use, keeping the
contents clean for repeated use.
The simple steps are as follows:
- Take a plastic bag and deposit a SMALL amount of grease in it.
