INSTALLATION OF THE
LIFTKLEEN
• SERVICE HOOK-UP
AIR
Units are supplied with a Lockable Air Switch
connection. Connect an air supply line to the
inlet of the master on/off valve located on the
side of the machine (see Figure 14). The
recommended air piping arrangement should
be followed to assure trouble-free operation
(see Figure 15). Once your line is connected,
make sure the air switch sleeve is fully
engaged to ensure proper air supply.
Note: The minimum operating air pressure is
85 PSI, however, operating at this pressure
greatly reduces the lift capacity of the unit.
We recommend operating the unit at 90-100
PSI for optimal performance. Maximum inlet
pressure is 110 PSI. A pressure gauge is
provided on the filter/regulator/lubricator
which is located on the side of the Liftkleen
washer next to the Air Switch Connection.
ELECTRIC
• On Liftkleen models with Superflo Pump
Assembly only, a junction box is provided
on the side of the unit for hook-up with the
appropriate electrical service.
• On Liftkleen models with electric heat
only, an electrical enclosure is provided.
The attachment points on the contactor are
appropriately marked.
• On Liftkleen models with both Superflo
Pump Assembly and electric heat, an
electrical enclosure containing a contactor
is provided. Connections on the contactor
are appropriately marked.
WARNING
The Liftkleen must be properly grounded.
CAUTION
Check the electrical specifications on the
nameplate to assure the proper connections.
On 3 phase models equipped with a Superflo
pump, make sure that the motor rotation is
correct; that is, counter clockwise when
viewed from the top. To reverse rotation,
switch any two of the 3 phase leads.
DRAIN – A 1-1/2˝ NPT female drain is
located on the bottom of the tank assembly. A
plug is installed at the factory. To make
connections to the drain, remove the plug
!
!
and install appropriate plumbing. It is
suggested that a shut-off valve be installed.
WATER SUPPLY – A 3/4˝ NPT pipe nipple is
furnished at the rear of the Liftkleen as
shown on Figure 8. This is intended as a con-
nection to a water source for filling tank or
make up supply for heated Liftkleen models.
• FLOOR MOUNTING OF LIFTKLEEN
Four (4) mounting holes for anchoring the
Models LKR and LKD Liftkleen to the floor
are located in the bottom of the channel
weldment assembly at the rear of the
machine (see Figures 9a,b). These holes
accommodate 1/2˝ diameter bolts. The
machine must be anchored to the floor at
these points. Failure to adequately anchor
the unit will affect its lifting capacity and/or
cause structural damage to the machine.
OPERATION
WARNING
Always stand clear of lid. To prevent injury,
keep head, hands and body clear of the lid, lift
platform and lift mechanism at all times. These
units have moving parts, pinch-points and
close tolerances. Always stand clear of the lift
platform and lid when operating as the lid
could unexpectedly open or the platform
operate. Keep hands and fingers away from
tank when operating platform.
• AGITATING LIFT PLATFORM
To operate the unit, first open the lid. On units
equipped with the pneumatically operated
lid, this is done automatically during the next
step. Press the "RESET" button. The
platform will rise to the top of the unit and is
now ready for loading. Please note, the
platform will not rise until the lid is fully open.
Once loaded, rotate the Oscillate Selector
Switch to the "ON" position. Press the
"START" button. Platform will descend to
down position and remain there until lid is
closed. Upon lid closure, the platform will
begin to oscillate and will continue to do so
until the operator depresses the "RESET"
button or rotates the Oscillate Selector
Switch to the "OFF" position. Be sure to open
lid when resetting platform. The platform will
not oscillate unless lid is closed. Those units
equipped with a pneumatically operated lid
will close automatically. If soaking is desired,
