I. Locating and Setting Up
Remove press from shipping container and ensure the machine is stable in the location it will operate in. Manually check to see if the press can rock or vibrate and adjust accordingly. Four holes are provided in the press base. We recommend the press to be bolted to the floor with 4 x ½" diameter screws.
II. Steam
1. The ½" steam inlet pipe, located on the right side of the press, should be connected to a 3-way pipe, one end directly feeding steam to the press head, and the other end feeding steam to the press buck via copper pipe.
2. The ½" steam outlet pipe, located on the left side of the press, should be connected to a 3-way pipe. The pipe on one end drains steam directly from the press head and is attached to a ½" ball valve to release water. The other end of the 3-way valve drains steam from the press buck through a Y-strainer via copper pipe. The steam should be discharged into a vented receiving tank of a condensation return system.
3. Ensure that the pH level of steam into the press be maintained at 7.5 ± 0.5 in order to maximum the life of the press. Failure to maintain adequate levels of pH will cause premature deterioration of machine parts.
III. Vacuum
The vacuum valve is located on the left side of the press. A 1½ (MDU-42) or a 2" (MDL-47) pipe should be connected to the air vacuum valve. The discharge line should be pitched upward to the air vacuum valve to allow condensation to drain into the discharge tank.
IV. Air
1. Air is supplied to the press via air supply line connecting the air compressor to the air regulator. The air supply line , usually a ⅜" pipe, connects directly to air regulator (part 13AR1) located on the right side of the press. The air regulator should be set to 100 PSI (~ 7 kgf/cm2). A water filter should be installed on the air supply line to ensure excess water is drained from the air supply line. We recommend an after cooler and air dryer be installed to maximize durability of machine parts and lower maintenance costs.
2. Air pressure is also controlled by the pressure regulator (part 13PR1) located behind the front panel of the press. The pressure regulator controls the pressure applied onto the buck when the head is in the pressing position. The pressure regulator should be set to approximately 60 PSI (~ 4 kgf/cm^2). If a different pressure setting is desired, adjust the pressure regulator accordingly.
Installation
I. Operating Principles
To operate the press:
1. Connect the steam supply line and open the steam inlet valve.
2. Connect the vacuum discharge pipe and open the vacuum valve. Turn off the ball valve (located on the left side of the press).
3. Connect the air supply line and open the air inlet valve.
4. Adjust the air regulator (part 13AR1) until the air gauge reads 100 PSI. Set the oil feed on top of the air regulator to at most "2". Do not allow this setting to exceed "2" as excess oil may damage the press.
5. Adjust the pressure regulator (part 13PR1) behind the front panel of the press until the gauge reads 60 PSI (~ 4 kgf/cm^2).
6. The press is ready for operation.
II. Manual Operation
Manual operation is available at any time for head steam, buck steam and vacuum. To manually control:(a) head steam - press down on the head valve lever located at the top of the press.(b) buck steam - press down on the left pedal.(c) vacuum - press down on the right pedal.Automatic features of the press may be turned off by locating the appropriate switch within the timer control panel (part 12TCP1) and turning it off.
III. Safety Features
Each operator should be aware of the following safety features prior to use.
(a) Two Hand Operation - to avoid accidental deployment of press head into its pressing mode, the press requires the use of two hands to operate.
(b) Anti-Lock System - the press comes equipped with a pair of button timer controls (part 12BTC1) within the timer control panel (part 12TCP1) that monitors the timing of each red (close) button as they are depressed. The button timer control will prevent the operator to hold one or both red (close) button down using a external object and operate the press using only one hand.
(c) Spring Loading - the press head is counterbalanced with springs so that the head will always open. The springs are designed so that if one spring fails, the remaining ones will be able to lift the head back to its open position.
(d) Fail Safe Design - in the event a power or air supply failure, the head will automatically revert to its open position.
