Warning For installation, choose a surface that is: flat; free of any flammable solids, liquids and gases; between 5 and 35°C; less than 85% relative humidity; free of dust; not exposed to direct sunlight; away from any heat sources; and well ventilated.

Do not install in a hazardous atmosphere

This product is not explosion proof. Use of this product in a dangerous atmosphere may cause a fire or explosion

Warning Warning Use recommended voltage, phase,

and capacity. Do not use a multi-plug extension cord. Using a multi-plug extension cord may expose

the unit to excess current and cause a fire Using an unsuitable power source may cause a fire or electrical shock hazard

Caution Exercise care when lifting the jack

The jack is spring-loaded. Without the glassware installed, the jack will rise quickly and could cause bodily injury. When raising the jack, apply downward pressure so the jack does not lift quickly.

To raise and lower the jack, turn the jack handle 45 degrees counter-clockwise. When the desired height is achieved, turn the jack hand clockwise 45 degrees to its original position. When the glassware is not installed on the unit, beware of excessive upward force exerted by the spring. Apply downward pressure to driving unit to counteract.

Before assembly, please familiarize yourself with the following parts.

1) Knob Bolt – Extends the height of the Manual Slide Shaft. Refrain from loosening too much

Caution Hold Condenser while adjusting the

Driving Unit angle

When the angle adjustment knob is loosened, the glassware may become unstable, fall, and break. To prevent this, hold the glassware in its upright position while adjusting the driving unit angle.

2) Stand Base Adjuster – located on the bottom and back of the base.

S Model

Caution Lift slowly when using the manual

slide shaft

Do not lift the driving unit and glassware quickly as this may cause one

of the glass pieces to break.

6

V Model

Caution Caution Do not touch the flasks or bath

while evaporating

Do not spill the sample or other liquids onto the driving unit

Flasks and bath are heated during operation. If you touch the flask or bath, you may burn yourself.

If a liquid is spilled on the driving unit, immediately wipe with a cloth and dry the unit completely before using. Contact with liquid may cause the electronics to ignite or malfunction.

7

T Model

Caution Do not insert your fingers between the

driving unit and manual slide shaft while lowering the manual slide shaft

If you loosen the bolt quickly, the driving unit may lower quickly, and your fingers may get caught in the jack.

Assembly Instructions

1) Attach Rotary Joint Ring to glass Rotary Joint with the tapered edge of the Rotary Joint Ring facing the Driving Unit.

2) Slide Rotary Joint into Driving Unit until a “click” is heard.

9

3) Attach Main and Sub-Vacuum Seals to the glass Rotary Joint. The two brown parts will touch and the tapered edge of the Sub-Seal will face outward.

4) Push Rotary Joint Ring into Driving Unit (it will snap into place). 5) For S Model, proceed to Step 7.

Attach Condenser Support (metal rod, knob bolt) to the Driving Unit. Leave some room for movement. (V and T Models Only)

Caution Glassware is fragile

Glass parts can be easily broken and may cause bodily injury. Take utmost care when handling and installing the glassware.

6) Attach glass Trap Manifold to the Driving Unit. (V and T Models Only)

10

7) Attach Condenser Column to the Trap Manifold (For S Model, attach Condenser directly to Driving Unit) with the coil inlet/outlet facing outward. (V and T Models Only) For S Model, attach the Condenser directly to the Driving Unit with the coil inlet/outlet facing upward.

8) For S Model, proceed to step 9. Attach the Condenser Clamp (metal/rubber) to the Condenser Support Rod. Wrap the Clamp Hook completely around the Condenser Clamp and attach it to one of the two holes near the Set Screw. Tighten the Set Screw and Knob Bolt so that the Condenser is secure. (V and T Models Only)

9) Attach the Receiving Flask (spherical) to the Trap Manifold (For S Model attach directly to Condenser) with the Ball Joint Clip (metal). Rotate Clamp Locking Screw until the Receiving Flask is tightly attached and secure.

10) Attach the Evaporating Flask (teardrop shaped) to the Rotary Joint using the

Joint Clip (green).

11

11) Insert the Capillary Feed Tube through the Trap Manifold. (V and T Models Only). For S Model, insert through top of Condenser.

12) Attach the glass Suction Nozzle to the top of the Condenser. (V Model Only) 13) Attach 2 Water Cooling Nozzles (blue) and the Vacuum Nozzle (white) to the

Condenser.

Cleaning and Care

Warning Caution Do not take the unit apart Use proper cleaning material

There are hot parts, pressurized water lines, and electronics inside the unit that may cause bodily injury, electrical shock, or a water leak.

Do not use benzine, liquid acid, or other petroleum emulsion for cleaning this unit. Do not pour

water on this unit

1) Turn off power and pull the power cord out of the outlet before cleaning.

2) Clean with a soft cloth or wet towel. If more aggressive cleaning is necessary, use a neutral detergent. After cleaning, wipe the unit completely so that it is dry and free of any detergent.

How to Remove the Rotary Joint

1) Stop operation and remove any glassware attached to the rotary joint.

2) Turn toothed Flask Remover counter-clockwise until a “click” is heard or the Flask Remover is completely unscrewed from the Driving Unit.

3) With one hand on each side of the Rotary Joint, push and pull the Rotary Joint downward until the Rotary Joint has been freed from the Driving Unit.

4) Squeeze the open end of the Rotary Joint Ring together to separate the Flask

Remover and Rotary Joint Ring.

5) Re-attach the Flask Remover to the Driving Unit.

How to Replace the Fuse

1) Disconnect the Power Cord from the Driving Unit.

14

2) Remove the Fuse Cartridge using a flat-head screw driver. The inner-most fuse is the main fuse and the outer-most fuse is the spare.

3) Remove the Main Fuse and replace it with the Spare Fuse.

Fuse Specs: 115V, 630mA Cat. No. 142720

How to Replace the Sleeve Pin

1) Remove the Sleeve Pin using a small flat-head screw driver.

2) Slide new Sleeve Pin into the slot. Make sure each of the 4 corners is in the groove.
