Instrument Description
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.

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
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.
