2. INTRODUCTION
The HMUV1825P is an Ultraviolet digestion system for the
digestion of water samples with a high organic content. The
process of digestion will break down complex organic compounds
into simpler organic compounds and release metal ions bound
within the organic material into the water sample. Once digested
the Heavy metal content of the samples can be measured using
the Trace2o Metalyser range of instrumentation.

3. SAFETY INFORMATION
The UV digester uses Ultraviolet light which is harmful to the human eyes.
To prevent exposure the viewing window is manufactured from a high quality
UV blocking acrylic and the device is fitted with safety interlock switches such
that if an attempt is made to replace the lamp while the unit is switched on it
will switch off automatically.
The unit contains no user serviceable parts and as such no attempt should
be made to open it. Any attempt to do so will invalidate the warranty. All user
serviceable parts are accessible from the outside of the unit.
It is important to note that the system contains a delicate quartz glass
component and as such care should be taken not to allow the unit to be
subjected to vibration or shock. Should the instrument receive a shock for
any reason it should be returned to the dealer for inspection.

4. SETTING UP THE UNIT
Remove the unit from its packaging and place lid upwards on a flat surface.
Connect the power lead from the power pack to the socket on the right hand
side of the unit.
Open the lid of the unit and locate the ‘Power’ switch
Depress the switch to the on position. The display on the timer will turn on.
Fill the supplied sample beaker with the desired volume of sample and place
the beaker in the holder. Place the two sample tubes into the beaker. The
system is a re-circulating system so only one beaker is required.

5. PROGRAMMING THE DIGESTION TIME
The digester is fitted with a programmable countdown timer. A digestion time
up to 10 hours can be programmed although 30 mins to 1 hour is sufficient
for most samples.
To set the timer press the ‘programme’ button. The seconds will flash. To
adjust the time press the + and - buttons to adjust the time up or down
respectively. Subsequent presses of the ‘programme’ button will step through
from seconds to minutes to hours. Pressing the ‘programme’ button again will
set the time. (If the digits are flashing the timer will not operate).
Once the time is set press the ‘start’ button. The pump will turn on and the
lamp will illuminate. This can be confirmed by looking through the viewing
window. The timer will start counting down and an alarm will sound when the
cycle has completed. If the logo does not illuminate the bulb will need
replacing. (See maintenance section).
After the sample is complete, press reset to set the time back to the pre-
programmed time.
Lift the tubes clear of the sample water and start the timer again. Run until
the tubes are empty of liquid.
Note : Running the pump dry will not harm the system.

6. CARE AND MAINTENANCE
Routine cleaning.
To avoid any cross contamination of samples the system should be rinsed
through with de-ionised water. Place the inlet tube into a clean beaker filled
with 50ml of de-ionised water and the outlet tube into a second beaker. Run
the instrument for 5 minutes to flush the tubes.
Once a week it is recommended to run a 0.1M solution of hydrochloric acid
through the pipes.
It is not recommended to use acetone or other polar aprotic solvents to clean
the UV Digester enclosure, as these can damage the unit. Trace2o
recommends the use of mild soap solution for routine cleaning of the
enclosure. The use of improper solvents will void the manufacturer’s
warranty.

Maintenance
The UV digester requires very little maintenance but periodic replacement of
the pump tubing and Lamp may be necessary.
UV Lamp replacement :
Carefully unscrew the locking ring from the top of the lamp connector.
Slowly remove the lamp from the holding by lifting it vertically. Pull the lamp
clear of the connector and lay it on the bench.

Trace2o UV Digester HMUV1825P Instruction Manual v3.0
Grip the white connector and white end of the bulb between thumb and finger
of each hand and carefully wiggle the two apart.
To fit a new lamp reverse the process taking care to insert the lamp back into
the connector slowly and with no force. If held vertical and lowered carefully
the lamp should slide easily back into position.
When refitting the top of the connector align the arrow on the top of the
connector with the front of the instrument. If the unit fails to turn on slacken
the locking ring and rotate the top of the connector with the arrow on slightly
clockwise or anti-clockwise until a click is heard and the display comes on.
Lock the top in this position.

Replacing the pump tubing
After fitting the new tubing run the pump for a few seconds to self-align the
tube.
Remove the pump
cover by inserting a
flat screwdriver
blade into one of the
slots and twisting.
Remove the two
sample tubes from
the two white inline
connectors
Pull the short tube out of the pump
housing.
Reverse the process to fit the new
tubing. When fitting the tubing first fit
the two white connectors into the two
slots and then squeeze the tubing
around the outside of the rollers.

9. POWER PACK
IMPORTANT INFORMATION FOR YOUR SAFETY
DO NOT SHORT CIRCUIT OR TAMPER WITH THIS UNIT. ALWAYS OBSERVE
CORRECT POLARITY AND SYSTEM VOLTAGE WHEN CONNECTING.
Failure to do so may lead to a HAZARDOUS situation, damage the pack or
equipment and may invalidate the warranty. Remove personal items such as
rings, bracelets and watches when working with batteries.
WARNING
Before initial use, the 230V AC portable power pack must be put on charge
overnight (16Hrs). Failure to do so may reduce the life of the product and
invalidate the warranty.
DESCRIPTION
This 100W Portable Power Unit provides a versatile and complete power
solution that is safe and easy to use. The power unit is fitted with one, high
performance, 12V 12Ah lead-acid battery. It gives one output available on the
outside of the unit, that is capable of powering loads up to 100W overall
(depending on temperature of operation). Also incorporated is a 'low voltage
disconnect' system, which prevents damage to the batteries due to over
discharge.
OPERATION
BEFORE OPERATING THIS EQUIPMENT READ ALL OPERATING
INSTRUCTIONS THOROUGHLY
FOR 230V AC OUTPUT:
1. Ensure the unit is turned ‘OFF’
2. Connect an AC output lead to the ‘230V AC OUTPUT’ output
3. Connect the lead assembly to the equipment
4. Press the ‘ON’ button of the unit (internally)
5. The ‘SYSTEM POWER’ LED should illuminate
In this state, the battery voltage is continually monitored. When the battery
voltage falls below approximately 10.6V, the 230V AC output will turn off to
protect the batteries from becoming over discharged

CHARGING
THE LID MUST BE FULLY OPEN AND WELL VENTILATED WHEN CHARGING
THE PORTABLE POWER UNIT. FAILURE TO DO SO COULD RESULT IN FIRE
AND/OR EXPLOSION.
TO CHARGE FROM A 230V AC MAINS POWER SUPPLY:
1. Turn off the unit and disconnect the output lead
2. Connect the mains input lead supplied with unit (IEC320-C14) to the
‘230V AC INPUT’ inlet
3. Connect the charger to a mains supply, and switch on
CHECKING STATE OF CHARGE
The state of charge is best checked 2 hours after any discharge or recharge.
1. Turn off all loads
2. Press the ‘ON’ button of the unit (internally) The ‘SYSTEM POWER’ LED should
illuminate
3. Press the ‘Push to Test’ button
4. The LEDs will illuminate to indicate the approximate state of charge of the
battery
STORAGE
To optimize performance and service life, it is recommended that the Portable
Power Pack is fully charged before and during extended periods of storage,
commonly referred to as a “refresh charge”. Please refer to the recommendations
listed in the table below:
Temperature
Shelf Life
0°C (32°F) to 20°C (68°F)
12 months
21°C (70°F) to 30°C (86°F)
9 months
31°C (88°F) to 40°C (104°F)
5 months
41°C (106°F) to 50°C (122°F)
2.5 months
Table above shows the normal storage time or shelf life at various ambient
temperatures
Lead-acid batteries self-discharge more rapidly in higher temperatures, therefore it
is not recommended that the batteries are stored above 30ºC and should never be
stored above 50ºC.
