Manual or Electric Hydraulic Lift Base Stands
These base stands offer infinitely adjustable height between 25.5 and 33.5
inches (648 to 851 mm), giving a Cabinet work surface height of 28.0 to 36.0
inches. The height is adjusted either by a manual (hand crank) or electric
pump that drives hydraulic rams in the legs of the stands. All of the
hydraulic stands are equipped with fixed feet, but can be converted to caster
wheels with the addition of Caster Kit #3784000. The Base Stands for each
Cabinet model is listed in Table 3-2 below.

Note: When installing the Cabinet on the hydraulic lift base stand, ensure that
the hydraulic lines and the electrical cord are clear of any obstructions before
installing the cabinet on the stand or operating the lift system.
Connecting the Biosafety Cabinet to Utility
Service Lines
Note: Some models have a solenoid valve connected to the service valve on
the right side, rear position. The solenoid prevents gas from flowing to the
service valve when the unit blower is off. It is the only service valve position
that can be fitted with a solenoid valve. Connect the gas service to the
solenoid valve.
The service lines (if any) should be connected to the tube fitting(s) on the
outside of the liner wall as shown in Figure 3-3. To install the tubing, follow
these steps:
1. Ensure that the tubing is ¼ inch O.D., soft metal, and that the end has
been completely deburred.
2. Route the tubing from the rear of the cabinet, ensuring that it will line up
with the slot in the back of the side panel. The slot is located from 8 ¾ to
11 ¼ inches (222 to 288 mm) from the bottom of the cabinet.
Note: Make sure that the tube routing will not contact any electrical wires.
DO NOT loop service line tubing within the side panels of the Cabinet.
3. Make sure that the nut on the tube fitting is loose, but do not remove it.
Look inside the fitting to make sure the tube ferrule is there.
4. Push the tube into the fitting until it is properly seated. The tube will go
approximately ¾ inch (19 mm) into the fitting.
