4.5 Draining Machine for Storage/Shipment
Prior to shipping or outside storage of a GE Water & Process Technologies E4H Machine, the
system should be cleaned with the appropriate cleaner, flushed with water, and protected
from biological attack with the appropriate solution for TFC membrane. The membrane
housings and piping lines of the machine must be completely drained. Any water remaining in
the piping of a machine may freeze, causing damage to the piping, pump, membranes, etc.
The party shipping or storing the machine is responsible for any damage resulting from
freezing.
1. Disconnect the inlet, concentrate and permeate outlets.
2. Drain all water from the cartridge filter housing.
3. Remove the tubing connections on the inlets and outlets of the membrane housings.
4. Open the concentrate valve.
5. Remove the drain plugs from all PVC manifolds.
6. Be sure the flow meters are drained by disconnecting the bottom fitting of each meter.
7. Allow the machine to drain for a minimum of eight hours or until the opened ports quit
dripping.
8. After draining is complete, reconnect all of the piping.
4.6 Membrane Installation
For machines with membranes not loaded at the factory, the following steps are to be used for
installation.
CAUTION!
The membrane is packaged in a small amount of
bactericide solution to prevent biological growth; provide
adequate ventilation when handling. The m e m b r a n e
m u s t b e kept moist at all times in order to prevent
possible damage to the membrane material.
