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, bolts and screws holding the
cabinet to the skid. The castors may then be attached. The cabinet should be pushed off the skid attaching the
castors on each corner as the castor base plates hang over the skid. IT IS RECOMMENDED THAT NO LESS THAN
TWO PEOPLE PERFORM THE SKID REMOVAL AND CASTOR ATTACHMENT PROCESS.
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 Gas Service
NuAire doesn't recommend the use of natural gas within the AHBSC, but if gas service is determined to be
necessary for the application, appropriate safety measures must take place. All NuAire AHBSC'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 determination has been made by the appropriate safety personnel, 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 AHBSC ON THE GAS SUPPLY LINE.
All NuAire’s AHBSC’s meet the safety requirements of UL and CSA for Laboratory Equipment. To comply with these
safety requirements, NuAire uses only certified gas valves. If external piping is required, only black pipe is used for
this application.
As previously stated NuAire doesn't recommend the use of natural gas within the AHBSC and ASSUMES NO
RESPONSIBILITY FOR ITS USE. USE AT YOUR OWN RISK. The Bunsen burner flame within the AHBSC not only
contributes to heat build-up; it also disrupts the laminar air stream, which must be maintained for maximum
efficiency. IF THE PROCEDURE DEMANDS USE OF A FLAME, A BUNSEN BURNER WITH ON DEMAND IGNITION IS
STRONGLY RECOMMENDED. DO NOT USE CONSTANT FLAME GAS BURNERS. During use, the Bunsen burner
should be placed to the rear of the workspace where resulting air turbulence will have a minimal effect.
