5.5.2 Sieve Bed Installation
To install the sieve beds, follow the sieve bed removal procedure in
reverse order. It is very important to tighten all tubes to elimi nate leaks.
However, do not over tighten.
To check for leaks, take the following steps:
1 Plug in the unit.
2 Set the unit’s ON/OFF switch to ON for three minutes with
the flowmeter closed to pressurize the system.
3 Set the unit’s ON/OFF switch to OFF, and unplug the power
cord.
4 Apply soapy water around the sieve bed tube connections,
and check for leaks.
NOTE
Leaks can be so small in air loss that
oxygen concentration is not affected
immedi ately. The sieve material can
become contaminated gradually.
Careful leak testing is important.

The cabinet fan for the NewLife is located in the back of the unit. Refer to
the troubleshooting chart in Section 6.0 of this manual for instances where
