DANGER - HIGH PRESSURE DEVICE
This vessel may cause loss of life, severe bodily harm, or property damage if not correctly installed, operated and
maintained. Read and understand all guidelines given in this bulletin before attempting to open, operate or service
this vessel. Failure to follow these guidelines and observe every precaution will result in malfunction and could
result in catastrophic failure. Misuse, incorrect assembly, or use of damaged or corroded components can
result in high-velocity release of the end closure. We recommend that only a qualified technician experienced in
servicing high-pressure hydraulic systems, open, close and service this vessel.
•
Read, understand and follow every guide- line in this bulleting. Failure to take every precaution may
void warranty and could result in catastrophic failure.
•
Install in an area where a vessel or piping malfunction that result in water leakage would not damage
sensitive or expensive equipment, such as electronic components. verify that head locking
components are properly placed and secured.
•
Inspect end closures regularly, replace deteriorated components and correct causes of corrosion.
•
Follow membrane element manufacturer's recommendations for loading elements into the vessel
(see Replacing Elements).
•
The vessel is designed for continuous use at a pH of 3-11 and for intermittent cleaning (max. 43.2
hours per year at a pH of 2-12).
•
Operate vessel at pressures and tempera- tures in excess of their specific rating.
•
Service any component until you verify that pressure is fully relieved from the vessel.
•
Use corroded components. Use of such components may result in catastrophic failure.
•
Pressurize vessel until after visually inspecting to ensure that the spiral retaining ring is correctly
installed.
•
Tolerate leaks or allow end closures to be routinely wetted in any way.
•
Use excessive silicone lubricant.
•
Pressurize vessel without element in place unless permeate ports are plugged internally.
•
Overtighten fittings in ports.
•
Use petroleum products on Noryl components.
•
Allow petroleum or silicone based products to come in contact with membrane elements during
installation or maintenance.
•
Use the vessel at negative pressure.
•
Pressurize vessel with Compressed Air.
•
Stand or climb on the pressure vessels, or the feed / concentrate or permeate ports.
The 25-300 Series of RO Pressure Vessel Housings are
designed to be used in water desalination systems at
operating pressures of up to 300 psi. Each model is ava-
ilable in lengths to house from one 40-inch long
elements and one of each 14-inch and 21-inch long
elements. Any make of 2.5-inch nominal diameter
spiral- wound element with a 1/4"diameter female
product water tube is easily accommodated. The 25-300 is
designed and built in accordance with the International
Standards. Please refer the G.A drawing for the hydrotesting
pressure. The vessels utilize a fiberglass reinforced
plastic shell for superior corrosion resistance.
