OVERVIEW

New Wireless BLACKMAX digital manifolds can be used as conventional, stand-alone
manifolds or can also be used with a free APP allowing a mobile device (running on
iOS or Android platforms) to communicate directly with and control select functions
on these models remotely. The resulting APP provides the HVAC/R technician with the
convenience of running and monitoring a BLACKMAX digital manifold (from up to 300
feet away), while also providing additional capabilities not found in non-wireless versions
(such as comprehensive views of system measurements, graphical depictions of test
functions, data logging, and more). If your mobile device is NOT available, your wireless
manifold may be operated as a stand alone device using the yellow keypad.

both Pressure Displays should now read zero.
This operation should be performed especially
if manifold has been dropped or pressurized
beyond 800 PSIG (55 bar) full scale.

PRESSURE HOLD OR VACUUM HOLD TESTING

The BLACKMAX MD100W and MD50W series manifold can perform Pressure Hold
and Vacuum Hold tests. Test pressures and durations are fully settable by the user.
Any test can be aborted at any time by pressing [CLR].

PRESSURE HOLD TEST

A pressure hold test should be used to determine if a large leak exists (not to determine
if no leak or small leaks exist). Electronic Leak Detectors are the only instrument to
determine leak rates less than 1 oz./year. In practice there should be no pressure hold
detected if the system is deemed leak proof enough to add refrigerant. Large leaks
should be found before adding refrigerant. Low cost tracer gas mixtures such as 95%
N2 and 5% H2 are popular and can be sensed by a CPS E_MOS leak detector.

1. At Main Screen [FIG.1] press [TEST]. The Test Pressure Set Screen will appear

VACUUM HOLD TEST

Normally, systems with vacuum levels within 250-500 microns are deemed as having a
good seal and are ready for charging. As with any recharged system, a good electronic leak
detector should be used to test for leaks after the charge has been completed. MD50W
or MD100W manifold series will function as accurate vacrometers when used with the
MDXVG Remote Vacuum Accessory (page 6).

APPENDIX D (BATTERY SELECTION AND REPLACEMENT)

For optimum life and economic value, CPS Products, Inc. recommends that MD50W and MD100W
manifold series be powered by rechargeable NiMH (nickel metal hydride) batteries. CPS Products
offers an optional “Charger Kit” (model MDXBK) that comes with a power adapter and 4 NiMH
batteries. Do not connect the battery charger if there are no rechargeable batteries in the manifolds.

NOTE: Alkaline batteries should not, and cannot be charged in the BLACKMAX MD50W or
MD100W Series. Battery charge status is shown by the battery indicator symbol in the upper
left [FIG.1] Main Screen and all other screens. NOTE: A slight increase in temperature near
the charging socket is normal. Remove battery door and install 4 AA size batteries, observing

battery polarity. When using rechargeable
batteries for the first time, turn manifold off
and connect one end of charger to Manifold
9V DC plug [FIG.26] and the other end to an
appropriate wall outlet socket. Charge NiMH
batteries for 2 hours. The Battery Symbol on
the display will blink during charging. MD50W
and MD100W manifold series can be used
while charging the batteries, but charging time
will be considerably extended. The preferred
way to use the Rapid Charging Feature is to
charge while the manifold is OFF.
