Location Considerations
•
Place the TOH unit as close as possible to the process for proper circulation and fluid
temperature control.
•
The area surrounding the unit must be free of obstructions to ensure proper ventilation of
internal components and ease of servicing. Allow a minimum clearance of at least 30
inches.
•
Never operate the unit in confined spaces. Air circulation is generally satisfactory for units
operated at lower (up to 500°F) temperatures. AEC, Inc. recommends special local
ventilation at higher temperatures for points where vapors can be expected to escape from
the unit (reservoir tank vent, etc.).

I WARNING!
PROLONGED OR REPEATED EXPOSURE TO VAPORS
GENERA TED AT HIGH TEMPERATURE MAY RESULT IN
EYE AND RESPIRATORY TRACT IRRITATION AND
INHALATION OF HARMFUL AMOUNTS OF MATERIAL.
CONSULT THE MATERIAL SAFETY DATA
SHEET (MSDS) FOR THE FLUID YOU ARE USING.
Note: Before storing your TOH unit, remove all residual water from the unit with compressed
air to avoid a potential freezing hazard. See Section 6-3 on Page 46 for more information .
