Tsl Cup Kit - Graco ProMix PD2K Installation Manual

TSL Cup Kit

The cup is used for either Throat Seal Liquid (TSL)
or ISO oil. These liquids prevent exposure of air or
moisture with the resin or catalyst at the pump throat
packings and dosing valves. The PD2K Proportioner
includes two TSL Cup Kits, one for each pump. The
cups supply TSL to the upper throat cartridge of the
color (70 cc) pump, to the upper and lower throat
cartridges of the catalyst (35 cc) pump, and to the
four pump dosing valves. When using isocyanate
catalysts, the cup attached to the catalyst side of the
PD2K Proportioner is used to supply ISO oil to the
upper and lower throat cartridges of the catalyst (35
cc) pump and the catalyst dosing valves.
NOTE: TSL and ISO oil must be ordered separately.
For TSL, order Part No. 206995, one quart (0.95
liter). For ISO oil, order Part No. 217374, one pint
(0.48 liter).
1. Slide the kit mounting bracket onto any side of
the pump's hex nut.
NOTE: Prior to mounting the cup, use a
permanent black marker to mark a horizontal line
on the front of the cup approximately half way
between the top and bottom of the cup. Mark a
second horizontal line approximately 1/4 in. (3
mm) above the first line. Shining a strong light
towards these lines will provide a shadow that
will be visible from inside the TSL cup.

NOTE: The pump's upper throat cartridge has
three ports (two are plugged). Move a plug (73d)
if necessary so the barbed fitting (73b) can be
put in the port closest to the TSL cup.
