Installation and operation
A SUPRApak filter unit is a high quality product manufactured to exacting standards. It is essential to
exercise care when handling and installing it into filter housings.
Before installation, it is essential to verify that the filter type selected is suitable for the fluid to be filtered,
and to follow the instructions listed below.
(a)
Wherever practical, wear gloves to prevent accidental contamination of the filter and avoid injuries
to your hands.
(b)
The installation and operating instructions supplied with the filter housing should be followed carefully.
(c)
Check that sealing faces on housing, adaptors and seal nuts are clean and undamaged.
Installation of SUPRApak modules in higher temperature applications
(a)
When using the SUPRApak unit at operating temperature above 40 °C (104 °F) a stainless steel sup-
port core must be fitted into the center core of the unit. If a stack of several units is used, a support
core must be fitted into each unit.
For information regarding the proper selection of stainless steel support cores, please refer to the operating
instructions for SUPRApak filter housings.
(b)
When interrupting (or stopping) a filtration that is run at elevated temperature with a feed fluid
that increases its viscosity when cooled down, the SUPRApak unit should be rinsed out with hot
water before stopping the process. Otherwise the feed fluid may thicken or even crystallize within
the cool unit and the unit may be irreversibly blocked or damaged and cannot be used any longer.
Alternatively, if only a short break is necessary, circulation of the hot medium in a closed loop may
be possible.
For information on how to install the product in the different types of SUPRApak housings, please refer to
the operating instructions for SUPRApak filter housings.

Rinsing prior to use
If possible, use demineralized, contaminant-free, room temperature water.
Depending on the application, rinsing with cold or warm water in the forward flow direction is recom-
mended, prior to putting the SUPRApak filter unit into operation.
The recommended water rinsing volumes and flow rates are shown in Table 4.
Table 4: Rinsing recommendations
Module type
Recommended volume
SUPRApak / S Modules
20 liter (5.3 gallons)
SUPRApak / M Modules
140 liter (37 gallons)
SUPRApak / L Modules
340 liter (90 gallons)
If requested, rinsing can be done in recirculation, with water, suitable fluid or product.
If a higher flow rate is available, rinsing can be done with a higher flow rate to shorten the rinsing time.
However, the maximum flow rate must be adapted to the filter media in use and the application and it
may vary. Please check the appropriate product data sheets for details, or contact Pall.
Rinsing of SUPRApak modules in higher temperature applications
When using the SUPRApak unit at operating temperatures above 40 °C (104 °F), the unit should be
rinsed directly before use with rinsing water of the same elevated temperature to rinse and at the same
time heat up the SUPRApak unit. Otherwise the feed fluid may thicken or even crystallize within the cool
unit and the unit may be irreversibly blocked or damaged.
Recommended flow
(per module)
1.5 times filtration flow
1.5 times filtration flow
1.5 times filtration flow

Sanitization in place with hot water
SUPRApak depth filter modules are not supplied in sterile condition. Oxidizing and chlorine-containing
cleaners must not be used for sanitizing.
Please check the appropriate product data sheets for parameters regarding sanitization, or contact Pall.
In cases where sanitization is allowed, please follow these guidelines: if possible, use demineralized,
contaminant-free water. Depending on the type of SUPRApak modules in use, sanitization with hot water
in a forward flow direction of filtration with a maximum temperature of 85 ºC (185 ºF) and a maximum
forward differential pressure of 1.5 bar (21.7 psid) is recommended for an individual period of 20 minutes.
Maximum cumulative exposure:
(a)
SUPRApak SW 5200- SW 7300 modules: Laboratory tests confirmed a minimum of 10 cycles @ 20
minutes each, for a cumulative exposure of 200 minutes. Actual field experience shows more cycles
are achievable, coupled with proper filtrate quality monitoring.
(b)
SUPRApak PW/SW 7700 modules: Sanitization is not recommended.
(c)
SUPRApak SR 5100 modules: Laboratory tests confirmed 1 cycle @ 20 minutes.
(d)
SUPRApak PH/SH 5700- PH/SH 7200 modules: Sanitization is not recommended.
(e)
SUPRApak PW 5200 - PW 7300 and PR 5100 modules: Laboratory tests confirmed a minimum of 20
sanitization cycles @20 minutes.
Sanitization at elevated temperatures does not require that a stainless steel support core be used, if the
continuous filtration operating temperature is below 40 ºC (104 ºF).
Product and back pressure surges must be avoided during rinsing, sanitization or filtration in order to
avoid damage and to achieve optimal use of the SUPRApak filter unit.
In order to avoid injuries from escaping hot water, it is imperative to observe the corresponding
safety and protection measures.
7
Steam sterilization in place with hot steam
SUPRApak depth filter modules are not supplied in sterile conditions.
SUPRApak PW 5200 to PW 7300 and PR 5100 modules have been confirmed to be steamable at 125 °C
(257 °F) for 20 minutes. Other types are not steamable. Please check also the appropriate product data
sheets for parameters regarding steam sterilization, or contact Pall. In cases where steam sterilization
is allowed, please follow these guidelines:
Use demineralized, contaminant-free water. Use forward flow only.
Maximum Cumulative Exposure: 10 cycles at 125 °C (257 °F) for 20 minutes.
In order to avoid injuries from hot surfaces or escaping hot steam, it is imperative to observe
all corresponding safety and protection measures.
8
SUPRApak filter module replacement
SUPRApak depth filter modules should be replaced according to the application requirements of the
process, when the maximum application-specific differential pressure has been reached (please refer to
Section 2.2), or when the flow rate has become unacceptable, whichever occurs first.
Discard filter units in accordance with local Health and Safety and Environmental requirements for the
materials present.
Due consideration must also be given to the nature of the contaminants on the filters before disposing of
used filters.
