Introduction
This manual is intended to provide an overview of MICRODYN AQUADYN
®
UA860 module and
basic information. This manual covers the design as well as the operating and maintenance
procedures of the MICRODYN AQUADYN
®
UA860 module.
Please completely read this instruction manual before handling and operating MICRODYN
AQUADYN
®
UA860 membrane modules. It is important to follow all instructions and operate the
modules only under the advised operation conditions. Mishandling may compromise the mod-
ule performance or damage the membrane module.

Shipping, Handling and Storage
Proper handling of the modules is required to maintain the chemical and mechanical integrity of
the membrane modules.
Shipping
2.1
Every MICRODYN AQUADYN
®
UA860 membrane module undergoes a stringent quality check
before leaving the membrane manufacturing site. The membrane module is preserved for stor-
age. All open ports are sealed with caps or plugs. For more information about the preservation
please refer to Appendix 7.4.
Upon receipt, and prior to installation, the modules must be inspected for physical damages
and accurate product identification. MICRODYN-NADIR or its representative must be notified
immediately in writing in
the event of damage, leakages or wrong product identification (serial
numbers etc.). In the event that damages have occurred during third party transportation, dam-
ages must be reported and documented to the freight forwarding company as well.
Packing
All MICRODYN AQUADYN
®
UA860 membrane modules are packed for transport directly at
MICRODYN-NADIR. Each membrane module is individually wrapped in plastic. MICRODYN
AQUADYN
®
UA860 membrane modules are either packed in single carton boxes or are packed
on a pallet with 9 or 12 membrane modules per pallet. For more information about the packag-
ing procedure please refer to Appendix 7.5.

Handling
2.2
Only remove the membrane module from its original packing when ready for commissioning
(see chapter 6.1). The membrane module should be handled with care at all times to avoid
damage. All personnel handling the membrane module shall use the appropriate Personal Pro-
tective Equipment (PPE) and also utilize proper lifting guidance. DO NOT use the connectors
to lift the module. Please ensure safety at all times when handling the membrane modules.

Form-No: TM-WW002 // Revision: A // Date: Oct. 10, 17
Avoid contact of the membrane module with any solvents or substances that are harmful to the
membrane modules, unless agreed upon and specified by MICRODYN-NADIR. The module
must be kept wet all the time, as the fibers will get damaged once the membranes get dry.
Always protect the module from impact or shock to prevent damage to both the membrane and
module.
Storage
2.3
The shelf life of each membrane module is one year from the date of delivery without ad-
ditional preservation measures as long as correct storage conditions are fulfilled.
For uninstalled membrane modules, it is recommended to store the modules in a cool, dry and
well-ventilated area protected from direct sunlight at an ambient temperature of between 5 to
45 °C in its original packing.
The connection ports of the membrane modules are sealed with caps and plugs from the facto-
ry and should be checked for tightness and leakages and it is not allowed to remove these caps
before installation.
Membrane modules can be considered to be in storage if they have been installed into a rack
and been blanked off and not in operation when the above mentioned storage conditions are
met. Doing otherwise renders the warranty void.
It is possible to remove used membrane modules from the rack and put them in storage. To
prevent damage to the membranes, the shut down procedure (see chapter 6.3) has to be fol-
lowed. For storage exceeding one year we recommend to add preservative as described in
Appendix 7.4.
