1.0 INTRODUCTION
Bio-Rad’s HydroTech Vacuum Pump is designed for use with the Model 583 Gel Dryer or any other conven-
tional slab gel dryer. It uses water, not vacuum pump oil, so it is easy to use, environmentally friendly, and
practically maintenance free. All parts are corrosion resistant, for long life and trouble-free operation.
Figure 1. HydroTech Vacuum Pump
1.1 FEATURES
The HydroTech Vacuum Pump features include:
• No vapor or liquid trap required
• No oil or expensive oil-related maintenance required
• Continuous cooling that ensures steady vacuum
• No expensive diaphragms to replace every other year
• Free air capacity sufficient to seal two gel dryers

2.0 SET UP AND BASIC OPERATION
The HydroTech Vacuum Pump is shipped fully assembled. To use the pump, simply fill the reservoir with
water and attach the vacuum tubing from the gel dryer to the HydroTech’s inlet port.
2.1 UNPACKING
Carefully inspect the shipping carton for any damage which may have occurred in shipping. Severe damage
to a carton may indicate damage to its contents. If you suspect that the contents have been damaged,
immediately file a claim with the carrier in accordance with their instructions before contacting Bio-Rad
Laboratories.
Cut the shipping straps and open the top flaps of the shipping box. Remove the foam inserts, and lift the
top portion of the shipping box over the vacuum pump. The vacuum pump should now be fully accessible
and can be easily removed from the bottom box.
Check the contents of the box against the supplied packing list. Remove the plastic bag from the unit and
inspect the unit for external damage. If any part is missing or damaged, contact Bio-Rad Laboratories
immediately.
2.2 SET UP
Follow the steps in Table 3 for setting up the HydroTech Vacuum Pump.
Warning
Do not continually operate the pump with less than the “MIN” level of water
in the tank. It could damage the pump.
Table 3.

a. Plug the quick disconnect fitting end of the pre-
assembled vacuum line into the vacuum inlet port.
b. Plug a barbed two-way connector (shipped with the
Model 583 Gel Dryer) into the other end of the pre-
assembled vacuum line.
2.3 BASIC OPERATION
Warning
Turn the vacuum line’s two-way valve to the closed position when the dryer
is not in use; the vacuum pump then can continue operating without foaming.

3.0 MAINTENANCE AND TROUBLESHOOTING
3.1 MAINTENANCE
The HydroTech pump’s reservoir water should be changed at least once a month or if frequent use of the
HydroTech has caused the water level to reach MAX. Regular reservoir maintenance helps maintain pump
performance and reduces foaming. To change the water, follow the steps in Table 5.
Table 5.
Maintenance Guide
Step Procedure Description
1. Turn off the Vacuum pump. Do not connect the drain line unless the pump is turned off.
2. Connect drain line to the Firmly push the drain line quick connect fitting into the
Reservoir Drain Port. reservoir drain port to open the drain valve. (See Table 2.)
3. Place drain line into a large Secure the open end of the drain line before turning on
bucket or sink. the pump, or it may begin spraying.
4. Turn on the pump. Draining the reservoir requires approximately 30 seconds.
Warning: Do not run the pump without water for
extended periods of time.
5. Turn off the Pump. Disconnect the drain line by pushing the button on top of
the reservoir’s drain port. The drain port will automatically
close.
6. Refill the reservoir with water. Fill the reservoir to the MIN mark with deionized or tap
water. Reinstall the cap.
