Each Bienfang
®
Vacuum Press 3648H, 4468H and 5298H
(floor stand included) is fully assembled, calibrated and
tested at the factory to pull a high level of vacuum in a
minimum amount of time. Once passed by the Quality
Control Department, the completely tested press and pump
are packaged and shipped together to ensure that each
customer receives a complete and tested unit.
During shipping and uncrating, the alignment of the top
and base of the press may be altered and require adjustment
by the user. In addition, placing the press on an uneven or
warped table surface may require adjustment of the leveling
feet and hinges by the user. Follow these instructions to
ensure proper operation.
Installation
For consistent long-term operation of the 3648H and
4468H, Bienfang recommends using the appropriate
Vacuum Press Floor Stand. First assemble the Floor Stand
following the directions supplied with it, then lift the press
out of the shipping crate and position it on the Floor Stand
so that each of the four feet fit into the top of a Floor Stand
leg. Using the bolts supplied with the Floor Stand, bolt the
two support brackets on each leg into the corresponding hole
underneath the frame. When complete, tighten each bolt
fully and the press can be moved into position.
As an alternative to the 3648H/4468H Floor Stand, a
heavy-duty, flat level table can be used. The press should sit
completely on the table, so a 46" x 53" or 57" x 77" surface
area is required. The recommended surface material is 3/4"
Grade B plywood or better. A table height of 30" is typical.
Make sure all four adjustable feet are fully screwed in, place
the press on the prepared table and adjust the feet individu-
ally so that the press is level front to back and side to side.
For a Qualified Electrician
The Bienfang Vacuum Press 3648H and 4468H are rated
for 230VAC/60 Hz Single Phase (with Neutral) on a 20 Amp
circuit. Actual line voltages between 208-230 VAC are
acceptable. The press power-cord has a NEMA L14-20P
twist lock plug which is UL listed for use in this application.
The 5298H is rated for 230VAC/60HZ Single Phase (with
Neutral) on a 30 Amp circuit. Actual line voltages between
208-230VAC are acceptable. The press power cord has a
NEMA L14-30P twist lock plug, which is UL listed for use in
the application.
If you choose to hard-wire direct to a junction box, the
12-gauge power cord (3 wire plus ground) is color-coded
using the conventional standards:
Red - L1 (Hot)
White - Neutral
Black - L2 (Hot)
Green - Ground
Note that separate ground and neutral lines must be
installed or the pump will not operate and the press will not
meet UL standards or safety codes.
After hookup is complete, check with the Power Switch ON,
the tacking iron outlet on the front of the press measures
110-120VAC between L1 and Neutral, that there are 0 Volts
between neutral and Ground and that there is continuity
between Ground and press frame..
Note: If there are any questions, call your distributor or Hunt
Technical service at 888-240-6021.
Leave at least 5" between the rear of the press and the wall
so the top has room to open easily. The vacuum pump
should be placed on the floor behind the press. The plastic
vacuum line tubing is already connected underneath the
press and the free end will have to be attached to the inlet
side of the pump. To attach, depending on the pump fitting,
slide the vacuum line firmly into the chrome fitting on the
pump until it snaps in place or tighten the brass nut onto
the pump fitting.
(TIP: Hunt recommends the use of a static guard mat in
high-static areas).
With the Power Switch OFF, plug the vacuum pump power
cord into the electrical outlet marked Vacuum Pump Only
on the rear of the press.
To check operation, close the press and turn the Power
Switch ON (on the side of the press). The programmable
systems controller should come on and display room
temperature, 0 time and 0 vacuum.
