Initial Setup; Location; Electrical Supply - OTC 5281 Manual Del Usuario

No. 5281 DPF Thermal Processing Unit is designed to thermally regenerate diesel particulate filters
(DPFs) for the purpose of converting the soot contained in the filter to ash. Once this has been
accomplished, a DPF cleaner, such as No. 5280, can be used to remove the ash more effectively.

Location

1. Choose a suitable location to set up the DPF
Thermal Processing Unit.
A. The area must have a concrete floor (no
carpet or linoleum) and be large enough to
avoid heat buildup around the unit. Allow
more than 305 mm (12 inches) of clearance
between the unit and surrounding walls or
combustible surfaces.
B. The unit must sit level on the bare concrete
floor; use shims if needed to level the unit.
CAUTION: Installing the unit on an
unlevel floor can stress the firebricks
inside the chamber, causing breakage.
C. There must be an active smoke alarm in the
room.
D. Sprinkler heads in the vicinity of the unit
should be either high-temperature or the
type that senses smoke rather than heat.
Unpack the Unit
1. Uncrate the unit and remove the shipping
materials.
2. Release the spring latches on the door to the
firing chamber (see Figure 1), and remove the
shipping material from inside the chamber.
3. Remove flammable materials from the room.

Electrical Supply

This unit requires a dedicated electrical circuit.
Comply with all state and local electrical codes.
1. Position the unit near a dedicated 240 VAC,
single-phase, 50 amp, electrical outlet.
2. The breaker panel for the outlet must be no
less than 1.2 m (4 feet) and no more than
7.62 m (25 feet) away from the unit.
