Section 2: Installation
2.1
Preparing the AutoBlock
Follow the instructions in Section 1.2, Uncrate the AutoBlock.
Residual water
may be found in the internal plumbing of your AutoBlock. This
includes the pump, reagent injection lines and drain lines. This water is non-
hazardous, and was used for system checks during quality control inspections.
2.1.1 Install Drain Line & Carboy
A) The drain line is located in the lower back portion of the AutoBlock. Route
the drain line downwards. There is an open space in the base of the AutoBlock
directly beneath the drain line fitting. Running the drain line through this space
will protect it from accidentally becoming pinched.
B) Position the 10-liter carboy under the AutoBlock; all AutoBlock waste fluids
drain by gravity. Therefore, the drain line path must continually flow downward
into the carboy. Shorten the drain line as much as is reasonable while still
allowing easy access to empty the container when needed. Attach the drain line to
the proper fitting in the carboy cap.
Injection of DI water in the manual mode should be performed prior to use
to insure the drain line and carboy are working properly.
2.1.2 Install the Exhaust Fan
Holding the fan assembly in hand, orient the 4” white vent duct towards the
ceiling. Aim the 4” black intake duct towards the 4” vent hole. (The vent hole is
located beneath the 5 Teflon intake ports on the right side of the AutoBlock.)
Align the machined slots in the top of the fan assembly with the silver brackets
above the vent hole. Slip the fan assembly machined slots onto the silver
brackets. The fan assembly should lock solidly into place and self-align the
blower intake duct with the vent hole. Visually inspect the black ring gasket used
to seal the black fan intake pipe. Make sure that the seal is snug against the side
panel of the AutoBlock. Plug the exhaust fan power cord into the receptacle
located on the back panel of the AutoBlock labeled Exhaust Fan 1.
2.1.3 Placement of Reagent Rack
Position the six-bottle reagent rack (optional) on the right side of your AutoBlock
directly beside the exhaust fan housing, preferably beside and not in front of the
fan housing. (For the dual system there may be two reagent racks-optional)
