5.2 Set-Up Instructions
Remove outer shipping protection (carton or crating). The cabinet is fastened to the base skid and it is usually the best
procedure to leave the skid in place until the cabinet is located in its approximate position to facilitate ease in handling.
It can then be removed from the skid by removing the banding holding the cabinet to the skid. It may be necessary to
remove the Control Center in order to gain passage through a doorway. It may easily be removed by following the
instructions on drawing BCD-19031.
It is recommended that no less than two people are present using a
lifting system for placement of the cabinet onto the base stand.
It is not recommended to manually lift the cabinet onto the base stand.
5.2.1 Base Stand Assembly
The base stand is shipped knocked down in a separate carton and is assembled per drawing BCD-16633 if
accompanied with the cabinet. Remove the banding holding the cabinet to the base skid. Lift the cabinet from the
base skid and place on the floor. Now lift the cabinet on top of the base and bolt the base stand to the cabinet
using two 3/8" - 16 x 3/4" bolts and washers provided for the front base stand tabs and two 1/4" acorn nuts for the
rear weld studs. Place the cabinet in its desired location.
The base stand storage cabinets will usually be shipped according to customer requirements. If it is shipped
unassembled, it can be assembled per drawing BCD-16633. It is recommended that the upper and lower base
stand braces be installed first, then the rear and bottom panels (the end panels are always prefastened). Once
assembled, fasten the cabinet per the above instructions.
Remove the cap protecting the drain valve threads and install the drain valve, on the bottom right front of the
cabinet using Loctite 242 furnished to the threads and rotate the valve body until it is secure (See BCD-16300).
5.2.2 Leveling
Using a level placed on the work tray, adjust the leg levelers, first, end-to-end then front to back.
The NSF approved leg levelers provide a ± 3/4" (20mm) adjustment.
5.2.3 Bench Installation (BCD-16300)
Place the cabinet on the bench with approximately a 2" (51mm) overhang clearance for installation of the drain
valve. If the drain valve is not desired, cap with 3/8” NPT fitting and place the cabinet in its desired location and
using RTV caulk, seal all around the base of the cabinet and the bench. This provides a tight seal to prevent bench
spills from migrating under the cabinet.
If a drain valve is desired, (NOTE, CHECK WITH YOUR SAFETY PERSONNEL FOR REQULATORY REQUIREMENTS (i.e.
LOCKING TYPE) OF DRAIN VALVE INSTALLATION) remove the handle from the valve stem to gain clearance for
valve body rotation. Add Loctite 242 (furnished) to the threads and rotate valve body until secure, with the valve
stem (for handle) on the left side. Re-install handle to valve stem. Adjust the cabinet on bench to provide a
1-1/2" (38mm) overhang and seal the interface of the bench and cabinet, using RTV caulk as above.
5.2.4 Gas Service
NuAire doesn't recommend the use of natural gas within the LFBSC, but if gas service is determined to be
necessary for the application, appropriate safety measures must take place. All NuAire LFBSC's have precautionary
warning labels that say the following:
Use of explosive or flammable substances in this cabinet
should be evaluated by your appropriate safety personnel.
Once the appropriate safety personnel have made the determination, the application of natural gas must
be performed in accordance to national, state and local codes.
IT IS ALSO STRONGLY RECOMMENDED THAT AN
EMERGENCY GAS SHUTOFF VALVE BE PLACED JUST OUTSIDE THE LFBSC ON THE GAS SUPPLY LINE.
All NuAire LFBSC's meet the safety requirements of UL and CSA for Laboratory Equipment. To comply with these
safety requirements, NuAire uses only certified gas valves. In addition, if external piping is required, only black
pipe is used for this application.
