please immediately contact the After-sales Service Department of the manufacturer

/ supplier.

Please prepare the following information and materials:

•Product serial number (on the instrument nameplate)

•Warranty card

•Description of problem phenomenon

•The method and operating steps you have undertaken to resolve the problem

•Your contact details including telephone number, fax number and email address.

Warranty

According to the manufacturer’s warranty clause, the warranty period of the product

is 24 months (since the purchase date) provided that it is used by the normal

operation method under the normal service conditions specified in the Manual. This

1.Safety notes

•Please carefully read the Manual before operating the product, and observe

the specifications on safe operation.

•Please properly keep the operating instructions for easy reference in case of

need.

•Please ensure only suitably trained personnel can operate this instrument.

•Please comply with the safety rules, personal safety and accident prevention

norms, especially when creating vacuum!

•According to the type of medium handled, please wear suitable protective

devices when operating the instrument; otherwise, the following dangers may

occur:

-Splatter of liquids

-Fly-out of parts

-Contamination of human body, hair or clothes by splattered substances

•Warning! Inhale of contact with toxic liquids, gases, spatters, vapor, dust,

biological or microbiological medium might cause damage to the operator.

•Place the instrument on a stable, clean, antiskid, dry & fireproof table surface.

•Make sure there is sufficient space above the instrument and the glass

assembly might exceed the height of the instrument.

•Before use, please carefully examine the instrument and accessories

especially the glass assembly for any damage. Please do not use any

damaged parts.

•Ensure the glass assembly is free of stress! Each of the following reasons

might result in damage to the glass assembly:

-Stress due to incorrect installation

-Effect of external mechanical force

-Sharp change to the ambient temperature

•Ensure the instrument will not move due to vibration when turning on the

instrument.

•Note the danger caused by the following circumstances:

- Flammable substance

- Flammable low-boiling-point medium

- Breakage of glass component

•Warning! Never distill or heat any substance whose ignition point is lower than

the temperature set for the safety of the heating bath.

•The heating bath’s safety temperature shall at least 25 °C lower than the

ignition point of the medium being handled.

•Please don’t operate or use this instrument in an explosive environment or

underwater or use this instrument to handle any dangerous substance.

•This instrument is only suitable for the medium that does not react with the

energy generated in the handling process in a way that might cause danger.

Meanwhile, the substance being handled may not produce danger due to

energy generated in any other manner such as illumination reaction.

•The instrument must be monitored all the time when operating the instrument.

•Please don’t operate this instrument under overpressure.

•To ensure the effective condensation of the motor system, please do not block

the vent of the motor system.

•Only use of the accessories in the list of “optional accessories” can guarantee

the operational safety.

•Please refer to the operating instructions for heating kettle.

•Please refer to the operating instructions for optional accessories.

•Please use this instrument in a closed fume hood or other suitable protective

device.

•Select the distilling device according to the amount to be distilled and the

distillation type. The condenser must work normally. Please monitor the flow

rate of the coolant at the outlet of the cooler.

•To prevent pressure buildup, the glass assembly shall be kept vented when

operating under normal pressure, such as keeping the condenser open.

•Please note that gases, vapor or other substances can pose danger through

overflow from the upper opening of the condensation tube. To minimize or

avoid such danger, please take suitable measures, such as connecting the

cooling tube and scrubbing bottle or other effective extraction devices

downwards.

•The glass evaporating flask may not be heated on one side. The rotating

evaporating flask must rotate at the heating phase.

•The glass assembly’ design pressure tolerance is 10mbar. The venting valve

(see the part of “Testing”) must be opened before heating and once again after

cooling. When performing vacuum distillation, the steam must be condensed

before release or released safely.

If the residue after distillation is likely to be decomposed when exposed to

oxygen, please add only gas for stress release into it.

•Warning! Please be careful be avoid the formation of peroxides, as the

decomposition of peroxides accumulated in the distillation process might result

in explosion.

Please protect any liquid forming peroxides from ray of light, especially

ultraviolet irradiation. Please be careful to examine formation of any peroxides

before distillation and to remove the peroxides if any. Many organics are easy

to form peroxides, such as methoxypyridine, diethyl ether, dioxane,

tetrahydrofuran, unsaturated hydrocarbostyril, such as tetrahydronaphthalene,

diene, isopropylbenzene, ketone and solutions of the aforesaid substances.

•Warning! The heating bath, heating medium, evaporating flask and glass

assembly might become hot in the operation process and remain hot for a

while after stop of the operation! Before further operation, please let each part
