Thermistor Sensors - The
enclosed clamps can be used to
take temperatures of pipes or
other round surfaces within its
jaw range (1/8” to 1-1/8”). This greatly improves the calculation of Superheat and Subcool
temperatures, as the sensor is virtually isolated from ambient conditions, allowing
sensors to read true pipe temperatures while attached.

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.

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. MD50 or
MD100 manifold series will function as accurate vacrometers when used with the MDXVG
Remote Vacuum Accessory [FIG.4].
1. Plug the MDXVG Vacuum Accessory into the upper right side of the manifold [FIG.12].

EVACUATING PROCEDURES
CHARGING PROCEDURE - LOW SIDE
MD50 2 Valve Manifold [FIG.26] MD100 4 Valve Manifold [FIG.27]
1.) The following instructions are to add charge to a pressurized system, known as “topping off”.
2.) Connect Low (A) and High (B) Service hoses to
service ports (E) and (D). All valves should be closed. 2.) Connect Low (1) and High (2) Service hoses to service ports (L) and (H)
3.) Connect a hose from the open port on tee (C) to
valve fitting on supply tank. 3.) Connect a hose from port (3) to refrigerant supply tank’s valve.
4.) Open supply tank valve. For blends, turn tank upside down or make sure liquid refrigerant is being
charged.
5.) Push valve core on tee (C) until refrigerant comes
out. This will purge the hose from the supply tank.
5.) Open valve (C). With hose disconnect from
port (4), slightly open valve (D) until
refrigerant comes out. This will purge the hose
from the supply tank.
6.) Turn refrigerant system on. Monitor pressure gauges. Use superheat and subcooling features to help
determine when charge amount is optimal.
7.) Slightly open Low Side Valve (A) to allow liquid refrigerant to flow into low side of equipment. Caution
should be used when charging liquid refrigerant into low side of a refrigeration system.
8.) Close Low Side valve (A) when desired amount of refrigerant has been added. Note the use of a scale
is required.
9.) Let equipment temperatures and pressures stabilize. Check superheat and/or subcooling levels.
Repeat charge if necessary.
10.) Once done, close off supply tank valve and disconnect all hoses. Use Caution as all hose connections
are under pressure.
Once charge is complete, an electronic refrigerant leak detector should be used to confirm leaks do not exist.

2.) Open Supply tank valve to fill manifold with liquid refrigerant.
3.) Set scale to record charge amount.
4.) Open High Side Valve (B). Monitor weight reading.
5.) Once desired charge amount has been reached, close High Side Valve (B) and supply tank valve.
6.) Start refrigeration system. Open Low Side valve (A) to allow all remaining refrigerant in manifold and
service hoses to charge into system.
7.) Close Low Side Valve (A). 7.) Close Low Side Valve (A) and Valve (C).
8.) Monitor Low and High Side pressures. Superheat and subcooling features of manifold can be used at this time.
9.) Disconnect service hoses from equipment. Use Caution as all hoses are under pressure.
Once charge is complete, an electronic refrigerant leak detector should be used to confirm leaks do not exist.
High Side Charging should be done on a completely evacuated system.

For optimum life and economic value, CPS Products, Inc. recommends that MD50 and MD100
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 MD50 or MD100
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.
FIG.28
When using rechargeable batteries for the first
time, turn manifold off and connect one end
of charger to Manifold 9V DC plug [FIG.28]
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. MD50 and MD100 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.
Sensor may become contaminated with dust, oil, etc. from pulling vacuums.
1. Never use a cotton swab or similar object to clean the sensor. This may damage the
sensor.
2. Open all knobs, valves, and cap all the ports except for the VAC port.
3. Invert the MDXVG and add about 1 tablespoon of 100% denatured alcohol into the VAC port
(see FIG 2) so as to flush out contaminants.
4. Gently shake the unit to produce a swirling effect of the alcohol inside the housing.
5. Turn right side up, open a port to pour out the rubbing alcohol.
6. Repeat the above procedure until the alcohol appears to be clean and clear of contaminants.
7. Check the gasket located inside the VAC port. If worn or deformed, replace with a new CPS
gasket (PN: HXG)
8. Open all ports to allow sensors to air dry (usually about 1 hour). DO NOT BLOW DRY.
