HEALTH AND SAFETY NOTES

PURELAB Option-Q products have been designed to be safe, however, it is important that personnel working on these units understand any potential dangers. All safety information detailed in this handbook is highlighted as WARNING and CAUTION instructions. These are used as follows: Mains power socket Fuse

WARNING!

ON/OFF switch

WARNINGS ARE GIVEN WHERE FAILING TO OBSERVE THE INSTRUCTION COULD RESULT IN INJURY OR DEATH TO PERSONS.

CAUTION!

Cautions are given where failure to observe the instruction could result in damage to the equipment, associated equipment and processes.

Mains power lead

2.1 Mains Power Supply

Electricity

It is essential that the electrical supply to the PURELAB Option-Q is isolated before any items are changed or maintenance work performed. The ON/OFF switch is located at the left-hand side of the unit. The mains power lead is located just behind the ON /OFF switch. WARNING!

2.2

THIS APPLIANCE MUST BE EARTHED.

Pressure

The main water supply pressure should be isolated and residual pressure released prior to removal of any cartridges or carrying out work on the unit. Switching off the electrical supply will isolate the source of pressure, but pressure trapped within the unit should be released by opening the dispense tap until water flow stops. Dispense tap

2.3

Dispense Tap

The PURELAB Option-Q unit is fitted with an ultra-violet lamp. The UV lamp is enclosed in a stainless steel chamber ensuring the operator will not be exposed to UV light.

Ultra-Violet Light

WARNING!

2.4

UNDER NO CIRCUMSTANCES SHOULD THE LAMP BE CONNECTED AND ACTIVATED WHEN OUTSIDE THE HOUSING.

Sanitization Chemicals

During the sanitization cycle a CT1 sanitization tablet is used and relevant safety information is included in this handbook. A safety data sheet conforming to COSHH regulations is also provided with the tablets and should be read before the tablet is used.

PRODUCT AND PROCESS DESCRIPTION

3.1

Product Description

This handbook covers the operator instructions for the PURELAB Option-Q unit. The PURELAB Option-Q water purification unit has been specifically designed to provide a supply of highly purified water. Typically the PURELAB Option-Q is operated with a Docking Vessel DV25 (Cat. No. LA621) which provides a reservoir of 25 liters of highly purified water. The PURELAB Option-Q can also be operated with alternative reservoirs providing the level control interface is compatible. (See Section 10 - Consumables and Accessories). The PURELAB Option-Q can be bench or wall mounted with an optional wall mounting kit available. A range of accessories are available to complement the unit. (See Section 10 - Consumables and Accessories, for detail).

Process Description

The PURELAB Option-Q process links four purification technologies, Reverse Osmosis, adsorption, ion-exchange and photo oxidation and also incorporates a re-circulation pump and an optional RO feed water boost pump. A sub-micron point of use filter is also available as an option. The unit is designed to operate from a good quality potable water supply, and produces either 7 or 15 liters per hour of purified water which is further purified and circulated through a treated water reservoir. The ultrapure water can be dispensed at 1 liter/minute. A graphics screen displays the system status and provides control by means of three function buttons. The water is processed and treated by the PURELAB Option-Q unit as follows: • Potable water enters through a strainer and inlet solenoid valve at either regulated mains water pressure, or is pumped by means of a feed water pump (optional), and passes through the pre-treatment cartridge. The pre-treatment cartridge has been designed to protect the reverse osmosis cartridges from particulate/colloidal matter and excessive free chlorine, which may be present in the incoming feedwater. • The pre-treated water then passes the sanitization port and through one or two reverse osmosis cartridges, set up in series, which split the flow into permeate and concentrate streams. The permeate water is further purified whilst the waste concentrate stream is passed to drain. • The permeate water passes through a water quality sensor which measures the conductivity of the water. • The permeate water is drawn into the main re-circulation stream by the re-circulation pump together with water from the reservoir and passes through the re-circulation purification loop. • This water is pumped directly through the UV chamber where it is exposed to intense multi wavelength UV radiation to provide continuous bacterial control and photo oxidation of organic molecules. • The partially purified water then passes through the ionexchange cartridge which removes dissolved ionic impurities from the permeate water. • Finally, the water is passed through a: • Water quality sensor, which measures the resistivity of the water. • Temperature sensor which temperature measurement.

provides

accurate

• The deionised water is either dispensed through a dispense tap, or returns to the reservoir. An optional point of use 0.2μm bacterial filter can be fitted to the dispense tap for added protection. • During periods of non-use the unit will automatically operate in intermittent re-circulation mode to maintain water purity with maximum efficiency.

5.1

Unpacking the PURELAB Option-Q

The following items should be supplied with your PURELAB Option-Q: 1. PURELAB Option-Q unit 2. Cartridge Pack LC163 3. Sanitization by-pass block fitted in the unit 4. Installation kit (LA513 or LA506) 5. Operator manual 6. Mains Lead

5.2

Positioning the PURELAB Option-Q

Before commencing with installation and operation of the PURELAB Option-Q unit, please read and observe the following points. Environment The unit should be installed on a flat, level surface, in a clean, dry environment. The unit can also be wall mounted against a vertical wall capable of supporting the weight (for this we recommend the use of the wall mounting kit Part No LA610). CAUTION!

Note:

If unit is to be wall mounted, ensure it is mounted on a substantial brick or concrete solid wall capable of supporting the operating weight of the system. If mounting the unit on the wall, use the wall mounting kit and follow the instructions included in the kit. Refer to specifications for unit weights.

The unit is designed to operate safely under the following conditions: Rear mounting locations points

• Indoor Use • Altitude up to 2000m • Temperature Range 5 - 40°C • Maximum Relative Humidity 80% @ 31°C decreasing linearly to 50% @ 40°C, non-condensating The unit is in Installation Category II, Pollution Degree 2, as per IEC1010-1.

Electrical The unit 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.

Mains power socket Fuse

ON/OFF switch

Drain A semi rigid flexible connection to a sink or suitable drain capable of handling at least 1.5l/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.

Mains power lead

Electrical Connections

Feed Water The feed water should be of good quality and comply with specifications provided. This should enter the unit via an 8mm (5/16") O/D semi rigid tube, and should be in the temperature range 1 to 35°C. CAUTION!

For pressurized feeds, the minimuIm direct inlet pressure is 4.0bar (60psi) and maximum inlet pressure is 6bar (90psi). Higher feed water pressures must be reduced using a pressure regulator valve (Part No. LA512).

Direction of water flow

Collar Mesh filter

Operating temperatures outside the range 1 to 35°C will cause damage to the PURELAB Option-Q unit.

Reservoir feeds to the PURELAB Option-Q unit should be positioned at the same height, or above the unit, to provide a positive flooded inlet pressure.
