Instrument Description
TO-Clean is a revolutionary canister cleaning system developed by Wasson-ECE
Instrumentation. The TO-Clean canister cleaner allows for fully automated
canister cleaning. The TO-14/15 compliant TO-Clean system was designed to
take the guess work out of canister cleaning. The twelve 6-liter canister capacity
will increase your lab’s efficiency. The system is fully automated, allowing the
user to start a cleaning cycle and walk away. Using the touch screen controller,
up to ten custom methods can be defined and loaded as needed. The system
also comes with an automated leak check method to ensure system
performance. This provides a high performance system that is easy to use as
well as consistent.
An on-board touch screen embedded controller makes system operation as easy
as pressing start. The controller allows the user to save up to ten different
methods. The user can define each method including: number of cycles,
pressure, and soak times. Once the method has been defined, it is saved and is
accessible for later use.
Product Features
•EPA Method TO-14/15 compliant
•12 canister capacity, expandable to 24 one liter canisters
•Embedded touch screen controller
•30 mTorr vacuum for 12, 6-liter canisters
•Automated system leak test
•Electronic valve control
•Custom-built trays for different canister sizes
•User defined methods
•Save up to ten methods
•Isothermal oven, controllable to 110°C
•Edwards RV-8 vacuum pump

Initial Setup

Initial Setup
Gas Supply
Connect all gas lines to the proper fittings, as described in the Hardware section.
Gas bottle regulators should be high quality two stage regulators. Set the gas
bottle pressures leading to the TO-Clean to the following gas pressures:
Gas Minimum Quality Maximum
Set Pressure
Nitrogen Ultra High Purity 60 psig
Valve actuation requires approximately 55 psig dry instrument air or nitrogen.
Industrial compressed “house air” is usually inadequate for valve actuation
without additional treatment. Water and particulates can damage the actuators.
Connect gases as described in the Hardware Description section.
Pack List
Unpack and inspect the system for any damage that may have been incurred
during shipment. Ensure that all of the items found in the pack list are present.
Table 1 lists the items that should be present with your order. This list may vary
depending on your order. Check the shipping pack list which is shipped with the
instrument for a more accurate description of what was shipped with your order.
If there is a variance between your shipped pack list and your order please
contact our shipping department at 970-221-9179 to reconcile these differences.

Power Requirements
The TO-Clean system and vacuum pump are configured for 120VAC/60
hertz. The TO-Clean requires one dedicated 20-amp circuit and the
vacuum pump requires a 15-amp circuit.

Hardware Description and Assembly
Place the TO-Clean on a bench top or on the optional system cart.
Vacuum Pump
The TO-Clean comes with an Edwards BOC RV-8 vacuum pump. Unpack the
pump and place it on the floor next to the canister cleaner. Attach the vacuum
hose to the top of the pump, using the metal clamp, as shown in Figure 1.
The oil mist filter and oil ballast have been pre-assembled at the factory and are
connected by a short piece of tubing. Unscrew the gray oil ballast cap and screw
the oil ballast into the threaded hole until tight. Remove the clear cap from the
black mist filter fitting on the pump. Place the oil mist filter on top of the black
fitting and secure using the metal clamp.
Unscrew the two gray oil caps on the pump and pour the oil that came with the
vacuum in either of the inlets. There is an oil level window on the back of the
vacuum. The oil reservoir should be 1/3 – 1/2 full. You should not need the
entire bottle for the first fill. Screw the oil caps back on before turning the pump
on.
For further information on the Edwards pump see the manual and CD included in
the shipment.

Dewar
The optional Dewar houses the U-Tube where contaminants are trapped. This
cleans the nitrogen entering the system and protects the pump from
contaminants in the canisters. Connect the Dewar brackets to the right side of
the TO-Clean as shown in Figure 2. Slide the Dewar into the brackets and place
both the vacuum and nitrogen U-tubes into the Dewar along with the provided
insulating cap.

Attach the vacuum hose from the pump to the Dewar U-Tube using the metal
clamp, as shown in Figure 3. Attach the vacuum hose which goes to the valve
assembly to the other side of the Dewar U-Tube using the metal clamp.
Figure 3 - Dewar Vacuum Hose Connections
Connect the 1/8” line from the compressed nitrogen regulator to the 1/8” Dewar
U-tube fitting as shown in Figure 4. Connect the other side of the 1/8” Dewar U-
Tube line to the bottom of the humidification chamber, described in the next
section. Once the system has been assembled, leak checked, and is ready to
run, the Dewar can be filled with liquid nitrogen or liquid argon. The user should
be able to lift the insulating lid with all the Dewar connections intact.
