coolant trays, adjusted as high as possible.
2.3 Water Tray Drain System
The material coolant system’s drain system collects water from the coolant trays, holds it in the
coolant system reservoir and recirculates
it back through the material.
2.3.1 Bung Installation
Locate the four drain bungs in the PVC
parts bag. Remove the coupling nuts from
each drain bung. Insert a bung into the
drain hole in each coolant tray and in the
parts catcher. Thread the nuts back onto
each bung underneath the coolant tray
and tighten securely using a large channel
lock pliers. Locate the male/female
couplers in the PVC parts bag. Thread
one PVC male/female coupler into each
drain bung.
Also thread one PVC coupler into the bung inside the parts catcher. This will allow the parts
catcher to hold water to help cool parts.
Teon tape or plumber’s tape can help seal the male/female coupler in the drain bung.

2.3.2 PVC Drain Installation
The PVC drain system is installed beginning at the parts catcher and then working to the end
of the trays. The PVC parts are numbered in order of installation. During this process the
Installer will also place and connect the coolant reservoir. Using PVC cement, install the parts
per diagram 2.3.3.

2.3.4 Placing the Cooling System Reservoir
Place the coolant reservoir according the diagram in section 2.3.3. Install the screens on the
drains feeding into the coolant reservoir. Secure using zip ties.
Fit the No. 5 and No. 6 PVC pieces through the grommets in the reservoir.
2.4 Water Pump
The material coolant system requires a water pump to be operational. Because customer
needs can vary, Bend-Tech does not supply a water pump with the coolant system. The
