Electrical
The units can be connected universally to any electrical
supply in the range of
100 - 240V and 50 - 60Hz. The mains
lead is supplied with a molded plug on one end and a molded
connector to the unit on the other. The unit should be
connected to an earth. The unit includes a battery which will
require changing on a periodic basis, typically every 3-5
years. (Contact local Service provider)
WARNING! DANGER OF EXPLOSION IF BATTERY IS
INCORRECTLY REPLACED. REPLACE
ONLY WITH THE SAME OR EQUIVALENT
TYPE RECOMMENDED BY THE
MANUFACTURER (3 VOLTS, LITHIUM
CR2032). DISPOSE OF USED BATTERIES
ACCORDING TO THE MANUFACTURER’S
INSTRUCTIONS.
Drain/Flush
A semi-rigid flexible connection to a sink or suitable drain
capable of at least 2.0 l/min is required. The drain point
should have a gravity fall below the level of the unit and any
connections direct to drain should have an air-break device
fitted.
On the Genetic & Bioscience units a separate flush line
to drain is required. The drain and flush drain lines should run
individually to a convenient drain point.
Feed Water
The feedwater should be potable water, pre-purified using
reverse osmosis, deionisation, or distillation. If using a supply
other than reverse osmosis treated, it is strongly
recommended that a 0.2 micron membrane filter is installed
prior to remove colloidal impurities. The feedwater should
enter the
PURELAB Ultra via an 8mm (5/16") O/D semi rigid
tube, and should be in the temperature range 1 to 40
°
C (34
to 104
°
F). To ensure optimum performance it is
recommended that the feedwater temperature be between 10
to 15°C.
CAUTION! Operating with feed water temperatures
outside the range from 1 to 40°C (33.8 to
104
°
F) will cause damage to the PURELAB
Ultra unit.
For pressurized feeds, the minimum direct inlet pressure is
0.07 bar (1.0 psi) and maximum inlet pressure is
0.7 bar
(10 psi). Feedwater pressures up to 4 bar (60 psi) must be
reduced using a pressure regulating valve (Part No. LA652).
CAUTION! High feedwater pressures which may
exceed 4bar (60 psi) must be reduced
using a pressure regulator with built in
pressure relief (Part No. LA575).
Failure to install the correct pressure
regulator will cause damage to the
PURELAB Ultra unit.
Reservoir feeds to the PURELAB Ultra unit should be
positioned at the same height, or above the unit, to provide a
positive flooded inlet pressure of approximately 0.07 bar
(1 psi).
