CAUTIONS:
The TUFFTM series of air sampling pumps are designed to be robust, however they
should not be dropped or subjected to mechanical shock. Do not suck in water, or
highly saturated or corrosive gases. Failure to comply will render the warranty invalid.
The air sampling pumps contain no user serviceable parts and if a fault is suspected
the instrument must be returned immediately to Casella CEL or to a Casella CEL
Approved Agency for repair.
The warranty does not extend to cleaning or general servicing of the instrument.
Pumps which are not in regular use, or those which have been left on the shelf for
several days, when switched on, may not display a true indication of the current battery
charge status.
To ensure accurate battery condition monitoring and charge status displays, it is
advisable to fully charge the pumps before use.

1. INTRODUCTION
The TUFFTM air sampling pump is produced in three models, the TUFF Standard,
TUFF Plus and TUFF Pro.
This handbook covers the entire range of TUFFTM air sampling pumps.
The TUFFTM was developed to provide sampling capabilities between 5 ml/min and 4.5
l/min, suitable for a wide range of applications including solvent fumes, asbestos
clearance and personal sampling of dusts. TUFFTM pumps are ideally suited to many of
the “Total” and “Respirable” dust sampling techniques detailed in the U.K. Health and
Safety Executive’s publication MDHS14, and in other international reference methods.
The information contained in this handbook relates only to the operation of Casella
CEL sampling equipment and is not intended to advise or influence your adopted
sampling strategy. For advice on appropriate sampling methods, refer to local
legislation and guidelines as dictated by the relevant national and regional health and
safety organisations.
Please make sure the TUFFTM and associated equipment supplied by Casella are not
damaged and the Inlet Nozzle is not restricted before attempting to use this instrument.

There are two methods of charging the battery.
1. When the battery is attached to the pump.
2. The battery on its own.
This section details both methods.

E.TIME WEIGHTED AVERAGE (TWA) PRO and PLUS ONLY (Fig. 8) (Only activated
when advanced mode is selected-see configuration chapter)
This mode allows the user to allow a known volume of sample to be taken over a
selectable time period (for example 120L over 8 hours.). In this instance if the pump
was set to 2l/min flow rate, it would only need to sample for 60 minutes over the whole
8 hour sampling duration. The pump will automatically switch on/off spreading the
sample on time over the whole duration evenly.
Use the UP/DOWN keys to step through the Menu Options until the TWA screen is
displayed.
Press ENTER to continue to the TWA Run screen. Use the UP/DOWN keys to set the
total sampling duration, e. g 8 hours.
Press ENTER to continue to the Exposure time setting. Use the UP/DOWN keys to set
the Exposure Time, e. g 1 hour.
The settings entered will provide 1 hours exposure time evenly spaced over the 8
hours running time.
Press ENTER to Start.
Figure 8 Time Weighted Average
To exit the program at any time press and hold ENTER. The display will count down 3,
