EQUIREMENTS

 

Follow basic safety precautions, including all national laws, regulations, and local ordinances in your 

area regarding the use of this unit. If you have any questions about local requirements, please 

contact the appropriate agencies. 

SOPs

 

Because of the range of potential applications this unit can be used for, the operator or their 

supervisors must draw up a site-specific standard operating procedure (SOP) covering each 

application and associated safety guidelines. This SOP must be written and available to all operators 

in a language they understand. 

Locations and Intended Applications Range 

SMOHP forced-air ovens are engineered for constant temperature forced-air drying, curing, and 

baking applications in professional, industrial, and educational environments. The ovens are not 

intended for use at hazardous or household locations.  

Power 

Your unit and its recommended accessories are designed and tested to meet strict safety 

requirements.  

 

Always hardwire the unit power feed to a protective earth-grounded electrical source that 

conforms to national and local electrical codes. If the unit is not grounded, parts such as 

knobs and controls may conduct electricity and cause serious injury. 

 

Position the unit so the end-user can quickly and easily disconnect or uncouple the power 

feed in the event of an emergency. 

 

Avoid damaging the power feed. Do not bend it excessively, step on it, place heavy objects 

on it. A damaged power feed can easily become a shock or fire hazard. Never use a power 

feed after it has been damaged. 

 

Use only approved accessories. Do not modify system components. Any alterations or 

modifications to your oven may be dangerous and will void your warranty.
