Step Procedure
2. Connect the AC power cord.
3. Turn the Power On/Off switch
to run the pump for two minutes.
4. Turn off the pump and check the
water level in the pump reservoir.
5. Connect the pre-assembled
vacuum line supplied with the
HydroTech pump.
6. Connect the vacuum tubing
from the dryer to the
pre-assembled vacuum line.
7. In an easily accessible stretch
of the vacuum tubing, cut the
tubing and insert the two-way
valve that's included with the
HydroTech pump.
8. If you purchased the optional
HydroTech vacuum gauge, cut
the vacuum line and insert the
gauge.

HydroTech Set Up
Description
Plug the AC power cord into the HydroTech power input
module and into a nearby AC outlet.
This ensures the pump is fully primed and air bubbles
have been flushed out.
The level should be between the MIN and MAX marks
on the reservoir. If the level is below MIN, add water;
if it is above MAX, drain water.
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.
Note: Minimize the length of vacuum tubing between
the dryer and the vacuum pump to achieve the best
system efficiency.
This valve keeps the pump under vacuum when the
dryer's vacuum seal is broken.
Warning: Always turn the valve to the Closed position
when the dryer is not in use. The Closed position shuts off
air flow to the vacuum pump and prevents the water in the
reservoir from foaming.
This gauge displays the vacuum pressure.
