Flush Before Using Equipment - Graco Check-Mate 800 Instructions Manual

Installation
Mounting
Mount the pump (A) to suit the type of installation
planned. F . 2 on page 7 illustrates a ram-mounted
IG
pump in a multi-valve header system. Pump dimensions
and the mounting hole layout are shown in
Dimensions, page 27.
If you are mounting the pump on a ram, refer to your
separate ram manual for installation and operation
instructions. Mounting Kit 222776 is available to mount
the pump on a 55 gallon (200 liter) ram.
Air Line
• Main air bleed valve (C): is required in your system
to shut off the air supply to the pump and ram.
When closed, the valve will bleed off all air in the
ram and pump, and the ram will slowly lower. Be
sure the valve is easily accessible from the pump,
located upstream from the air manifold (G), and
downstream from the air regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
splashing or moving parts.
• Air line lubricator (D): provides automatic air
• motor lubrication. Locate in the position shown.
• Pump air bleed valve (E): required in your system,
to relieve air trapped between it and the air motor
when the valve is closed. Be sure the bleed valve is
easily accessible from the pump, and is located
downstream from the air regulator.
6
• Air Regulator (F): controls pump speed and outlet
pressure by adjusting the air pressure to the pump.
Locate the regulator close to the pump, but
upstream from the pump air bleed valve.
• Air manifold (G): has a swivel air inlet. It mounts to
a ram, and has ports for connecting lines to air
accessories, such as the ram air regulator (T) and
ram director valve (U).
• Air line filter (J): removes harmful dirt and moisture
from the compressed air supply. Also, install a drain
valve (W) at the bottom of each air line drop, to
drain off moisture.
• Air shutoff valve (K): isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.
• Pump runaway valve (V): senses when the pump
is running too fast and automatically shuts off the air
to the motor. A pump which runs too fast can be
seriously damaged. Locate in the position shown.
Fluid Line
• Fluid drain valve (M): required in your system, to
relieve fluid pressure in the hose and dispense
valve
• Fluid shutoff valve (P): shuts off fluid flow.
• Fluid pressure regulator (L): for more precise
adjustment of the fluid pressure.
• Dispense valve (S): to dispense fluid.
• Fluid line swivel (R): for easier dispense valve
movement.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
