Mounting Instructions

Bench/Work Table

The following method of mounting your T-420 equipment 
package is offered as a guide and may be varied to suit your 
particular needs.

1.  Prepare mounting surface for T-420 press and pump.  
 

 

 

IMPORTANT: Care should be taken to ensure the  

 

 

mounting surface is capable of supporting the weight  

 

of the press (210 lbs.) and power source (75 lbs.)

2.  Remove shipping carton from T-420-1 press. There are  
 

two 1/2-13 tapped holes in top of plate which may be  

 

used for lifting purposes (see Figure 1, Page 4).

3.  Using an adequate lifting device, raise the press to    
 

the mounting surface. Align holes in press support    

 

brackets with holes in mounting surface. Insert bolts  

 

through top of mounting surface. Washers and nuts are  

 

installed from underneath. Tighten.

4.  Place the T-421U power unit on mounting surface to  
 

the right and slightly behind the T-420-1 press

5.  Mark mounting hole location for power unit and drill  
 

holes in mounting surface.

6.  Replace power unit and align holes on mounting    
 

surface with base plate on power unit. Insert bolts    

 

through top of mounting surface. Washers and nuts   

 

are installed from underneath. Tighten.

7.  Remove plug from outlet port in pump.

8.  Locate the T-421U power unit on mounting surface to  
 

the right and slightly behind the T-420-1 press.

9.  Connect Hose assembly (T-410-22) to 4315X8 For-Seal  
 

adapter on press and pump. Tighten.

10.  Before the electric pump (T-421U) can be activated,    
 

the male and female electrical disconnects must  

 

be mated.

11.  Plug electric cord into a grounded, 220 volt, 60 cycle,  
 

single phase outlet. THE PUMP MUST BE ON  

 

AN INDIVIDUAL 15 AMP FUSED ELECTRICAL  

 

 CIRCUIT.

 

If using T-421U-110 pump, plug electric cord inot a grounded  

 

110 volt, 60 cycle, single phase outlet. The pump must be on  

 

a 30 amp fused electrical circuit.
