INSTALLATION
Upon receiving the VWR Dylastir/Dylatherm/Dyla-Dual, check to ensure that no damage
has occurred in shipment. It is important that any damage that occurred in transport
is detected at the time of unpacking. If you do find such damage the carrier must be
notified immediately.
After unpacking, place the Dyla Series unit on a level bench or table, away from
explosive vapors. Ensure that the surface on which the unit is placed will withstand
typical heat produced by the unit and place the unit a minimum of six (6) inches from
vertical surfaces. Always place the unit on a sturdy work surface.
The Dyla Series unit is supplied with a 3-prong power cord that should be plugged into
a standard 3-prong grounded outlet. If the cord supplied does not meet your needs,
please use an approved power cord that suits local codes and electric supply.
Replacement of the plug must be made by a qualified electrician.
MAINTENANCE & SER ICING
The Dylastir/Dylatherm/Dyla-Dual is built for long, trouble-free, dependable service.
No lubrication or other technical user maintenance is required. It needs no user
maintenance beyond keeping the surfaces clean. The unit should be given the care
normally required for any electrical appliance. Avoid wetting or unnecessary exposure
to fumes. Spills should be removed promptly after the unit has cooled down. Do not
use a cleaning agent or solvent on the front panel which is abrasive or harmful to
plastics, nor one which is flammable. Always ensure the power is disconnected from
the unit prior to any cleaning. If the unit ever requires service, contact your VWR
representative.

STIRRING OPERATING INSTRUCTIONS
1. Get ready:
Turn stir knob to the off position, at the extreme counter-clockwise position. Plug
power cord into a standard 3-prong grounded outlet. Place a vessel with the
solution and the appropriate accessories in the center of the top plate.
2. Set speed:
Slowly turn the stir knob clockwise until the pointer reaches the desired set speed.
The stirrer may initially have to be set at a higher speed to overcome friction in
the motor and the material being stirred.
3. Adjust speed:
Speed adjustments can be made without interrupting stirring by turning the
indicator knob clockwise to increase speed, or counter-clockwise to decrease speed.
4. Stop:
To stop stirring, turn the stir knob to the extreme counter-clockwise position, until
it clicks. Your vessel can then be removed. The stirring knob should be kept in the

HEATING OPERATING INSTRUCTIONS
1. Get ready:
Turn heat knob to the off position, at the extreme counter-clockwise position. Plug
power cord into a standard 3-prong grounded outlet. Place a vessel with the
solution and the appropriate accessories in the center of the top plate. This is
important because the vessel should be over the hottest part of the top plate.
2. Set temperature:
Turn the heat knob clockwise until the pointer reaches the selected heat setting.
As soon as this is done, the red pilot light will flash on and will stay illuminated
until the hotplate reaches the selected temperature setting (graduations on the
panel surrounding the control knob are reference marks only and do not indicate
specific temperatures). The pilot light will continue to light intermittently as the
thermostat acts to maintain this temperature. Rotating the heat control to its full
on position will bring the hotplate surface to its maximum temperature of about
400°C. After cycling for a short period, the plate temperature should stabilize
between 350°C and 400°C, when the control setting is left on "HIGH". To prevent
possible damage, however, this position should not be maintained indefinitely. DO
NOT allow the unit to operate at maximum temperature without a beaker or flask
(with fluid) on the top plate.
3. Adjust temperature:
Temperature adjustments can be made without interrupting heating by turning the
indicator knob clockwise to increase heat, or counter-clockwise to decrease heat.
4. Stop:
To stop heating, turn the heat knob to the extreme counter-clockwise position.
Your vessel can then be removed. The heating knob should be kept in the off posi-
tion when not in use.
