Installation, Operation and Care of
WR SERIES
ENGINEERED WASTE SYSTEMS
SAVE THESE INSTRUCTIONS
GENERAL
The WR Series Engineered Waste System is comprised of one or more pulpers, a piping system and
a waterpress. The pulper uses a 7.5 horsepower motor, stainless steel components and carbide steel
cutting edges to shred grindable waste to a pumpable slurry. The slurry is pumped through the piping
system to the waterpress where a stainless steel screw squeezes out the moisture, compacts the waste
and lifts the semi-dry pulp to the discharge chute — reducing the original volume significantly. Process
water is pumped back to the pulper(s) where it recycles.
Modular design of the WR Series Engineered Waste System allows one or more pulpers to be located
remote from the waterpress. Required piping to connect the waterpress to the pulpers is to be supplied
by others and installed per Hobart piping drawing. Pumps, motors and controls are supplied per the
order and the sales installation drawings. Because each installation is unique to the site, follow the
sales installation drawings carefully during the installation process.
Additionally, the pulper may be installed undercounter with a water-tight trough connection; a silversaver sink with lift-out basket (by others) can be installed with the trough.
INSTALLATION
Prior to installation, test the electrical service to make sure that it agrees with the specifications. Plan
the location of plumbing and electrical components for operator safety, ease of operation and cleaning.
UNPACKING
Immediately after unpacking, check for possible shipping damage. If the units are found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery. Identify and
group the components, matching with the proper units. Do not discard or misplace components. Do
not mismatch components with the wrong units.
LOCATION
Both the pulper and the waterpress should be located near a floor drain; floor should be pitched a
minimum of
operation, cleaning and service.
LEVELING
Vibration Isolation Pads (standard, Fig. 1) must be installed under each
Leg of the pulper and slurry pump before making connections. Level by
threading the Adjustable Feet up or down as necessary. After leveling,
tighten the Setscrew on the Foot Flange.

FEED TRAY (Optional Lengths) AND HOOD (Standard)
The feed tray extending from the pulper is available in three lengths: Short (20"), medium (36"
standard) or long (42"). The hood is positioned over the pulper and has an interlock. When the hood
is lowered, material can move from the feed tray to the pulper through the curtains. The feed tray and
hood can be installed in one of three 90° positions (Fig. 2).
TRAY FLUSH (Optional with Feed Tray and Hood)
When equipped, the tray flush is attached to the end of the feed tray. The tray flush is plumbed to the
return water line, either at the factory or in the field by qualified installer or technician.

UNDERCOUNTER (Optional)
Undercounter models use a feed table (by others) with transition ring (by Hobart) welded underneath
the feed table per instructions (Fig. 3) instead of the Feed Tray and Hood. Install the reed switch packed
at the junction box to the location indicated (Fig. 3). Undercounter models are provided with either a
cover plate or a single opening feed hood, which must be placed over the pulper opening of the feed
table. On undercounter models, either the cover plate or the single opening feed hood is the pulper
cover.
If equipped with a cover plate, rotate the cover plate so the magnet aligns with reed switch and the cover
plate will drop flush into the feed table opening.
If equipped with the single opening feed hood, the magnet is factory installed in the location opposite
the feed opening. This location is appropriate only if the feed opening is oriented 180° from the slurry
pump assembly. If the feed opening is positioned at either 90° orientation, relocate the magnet
assembly so it aligns with the reed switch. The single-opening feed hood drops into the table opening
so it is level and the magnet operates the reed switch.
The magnet and reed switch will always be located next to the slurry pump assembly.
