CPS BlackMax Operating Instructions

BlackMax™ 2-Valve Piston Manifold
<<<WARNING>>>
Follow good safety practices when working with
refrigerants and refrigerant equipment. Safety goggles
should be worn at all times. Refrigerant and lubricant
vapor or mist may cause injury, frostbite, irritate eyes,
nose and throat. Avoid breathing or contact with skin.
Always point hose away from you and anybody near or
around you. Remove hoses with care as they may be
under high pressure with refrigerants. Improper proce-
dures can cause refrigerant gas under pressure to
explode violently. This equipment is intended for use by
experienced professional service technicians in the
refrigeration and or air-conditioning who are familiar
with the equipment they are servicing. Review the
material safety data sheet (MSDS) provided by the
refrigerant manufacturer for safe and proper handling
information as well as instructions as to what to do if
an emergency should arise.
2-WAY MANIFOLD FUNCTION
1. The right side hand knob (red high side) will control
the flow of ports on that side to the center port and
the port on the left side (blue low side) providing the
low side hand knob is in the open position.
2. Should the flow be needed only through the center
port (yellow line) close the low side blue label hand
knob.
3. The low (blue) side operates in the same manner as
on the high (red) side.
4. Pressure gauges and compound gauges are color
coded accordingly.
5. The gauges will indicate either vacuum or pressure
whether the hand knobs are in the open or closed
positions, (if the hoses are connected to either a
refrigerant supply tank, recovery unit, A/C system or
vacuum pump etc).
EVACUATING PROCEDURE
1. Remove all refrigerant from the system. NOTE: It is
unlawful to discharge or exhaust refrigerants into
the atmosphere. CPS strongly recommends the
practice of recovery or recycling.
2. Connect a vacuum pump to the center yellow
charging hose.
3. Connect the high side service valve of the system to
the right side red charging hose.
4. Connect the low side service valve of the system to
the left side blue hose.
5. Fully open the high and low side hand knobs.
6. Start the vacuum pump.
7. Evacuate the system according to the manufactuer's
specifications; close the high and low side hand
knobs.
8. Turn off the vacuum pump.
9. Disconnect the yellow charging hose at the vacuum
pump end and connect it to the refrigerant supply
tank. (Make sure to turn shut off valve, off before
disconnecting).
