Service manual

If the magnets are hanging freely at the 6:00 position and about 1/16” off the bottom, the problem will be a
faulty REED SWITCH or misalignment of both magnet and switch. Test by using a large magnet (one strong
enough to pick up a screwdriver). Put it up to the reed located on the underneath side of the wash or rinse
tanks near the front corners of the machine. If the machine turns off, the switch is okay and the problem will
be alignment of the inside magnet and the switch mounted outside. The switches are ‘normally closed’ and
different from typical reed switches used by others.
CHEMICAL FEEDERS
ADS Conveyors and the High Temp door machine require commercial chemical feeders or dispensers. If
you are using the machine as a chemical sanitizer, that requires a three-product dispenser. If you are
using the machine for high temperature sanitizing, a two-product dispenser is needed. Installation and
service questions of the feeder units are referred to the manufacturer.
PLUMBING DRAINS
“If there is a grease trap but the machine drains are just a little higher than the trap, can it still be used to
connect the dishmachine drain?”
The answer is no, water only drains down hill. When this rule is not followed, it results in leaks and foul
smells.
“If there is a wall drain but the machine drains are just a little higher than the wall drain, can it be used to
connect the dishmachine?”
The answer is no, water drains down hill. For a wall drain you must install a trap to prevent sewer gas from
entering the room through the pipe. This will bring your wall drain access even lower. Typical access points
for drains on conveyor and high temp equipment is 8” off the fl oor.
“The drain discharge on the machine is on the opposite side of the machine from the building drain or the
building drain is under the machine, can I make a few “U” turns to reach the building drain?”
NO, tight bends in piping is not recommended. The soil load will clog the drain line at the 90° elbows; straws
and toothpicks create “nesting” and cause repeated service calls and fl ooding. Clean outs are
needed if tight 90s are used in the drain plumbing.
“What size drain line can I use on a conveyor or high temp door machine?”
Use 2” pipe or larger. Never use reducers and always drain to larger diameter pipe.
“Can I use “FLOOR SINKS” for Conveyor or HT tank drains?”
Yes, but caution should be used. Make certain the drain is free running and a “deep” fl oor sink is used (no
shallow types). When the machine is emptied, 15 gallons will come fl ooding out all at once. Test before you
commit.
