of an enclosure.
• If the conduit must be placed in the top of an

keep water from entering the enclosure.
• The Vission 20/20 is supplied with pre-
punched conduit holes. Use them!
• Don’t:
• Don’t run wires through the Vission 20/20
enclosure that are not related to the compres-
sor control.
• Don’t add relays, timers, transformers, etc. in
the Vission 20/20 enclosure without fi rst check-
ing with Vilter.
• Don’t run conduit into the top of an enclosure.
• Don’t run refrigerant tubing inside the
enclosure.
• Don’t drill metal enclosures without taking
proper precautions to protect circuit boards
from damage.
