FAQs
Q: Should a filter drier be used on the inlet side of my recovery machine?
A: Yes, installing a filter drier prior to the recovery machine prevents non-condensable from
entering the recovery machine. We recommend using a new filter dryer for every recovery.
Q: Can I draw down a system prior to charging with the MalcoEdge Velo-X Recovery Machine?
A: No, the MalcoEdge Velo-X Recovery Machine is designed to recover refrigerant. A vacuum pump
would be used to draw a deep vacuum or run a decay test.
Q: How do Microns compare to PSI?
A: 0.000019337 PSIG = 1 Micron Mercury (If you get under 500 microns you are dealing with a deep Vacuum)
Q: What are the differences between a recovery machine and a vacuum pump? Are they used for the same
tasks or separate tasks when servicing an HVAC/R system?
A: The MalcoEdge Recovery Machine removes liquid refrigerants, moisture, and vapor from a system that has
previously been charged prior to service. A recovery machine does not typically draw a system into a deep
vacuum. A MalcoEdge vacuum pump on the other hand removes any vapor from a system and draws the
system down into a deep vacuum. A vacuum pump would also be used to perform a decay test.
Q: How fast will a MalcoEdge Recovery Machine remove refrigerant?
A: The Malco Edge Recovery Machine will remove R-22 at a rate of 0.71 lb/min vapor or 9.03 lb/min liquid.
See the user’s manual for flow rates using other refrigerants.
Q: Is the MalcoEdge Recovery Machine AC or DC?
A: The MalcoEdge Recovery Machine is powered by AC, but the motor is a variable speed DC motor, so
the system can ramp up or down when working with liquid or gaseous refrigerants.
Q: When should I use a MalcoEdge Recovery Machine?
A: A MalcoEdge Recovery Machine should be used when servicing an existing HVAC/R system. To service
a previously charged system, the liquid and vapor refrigerant must be removed from the system and pumped
into a recovery tank. Once removed, a technician may then service the system.
Q: Do I need to change any settings on my recovery pump when the machine changes from extracting liquid to vapor recovery?
A: There are no settings to switch when using the MalcoEdge VeloX Pump.
Q: What is the silver knob at the front of my MalcoEdge Recovery Machine?
A: The silver component is for a shoulder carry strap which is included with the MalcoEdge Recovery Machine.
Q: Does the MalcoEdge Recovery Machine require oil?
A: No, MalcoEdge recovery units do not require oil.
Q: Does the MalcoEdge Recovery Machine turn off when they have reached a certain vacuum level?
A: The MalcoEdge Recovery Machine automatically shut off once it has drawn the system down to 10 inHg.
Q: My MalcoEdge Recovery Machine flash code is showing me a high pressure shut off code. What does this mean?
A: The MalcoEdge Recovery Machine will display this code when the recovery tank is full. The MalcoEdge Recovery Machine
will automatically stop filling a recovery tank when it reaches 550 PSIG.
Q: A technician I know places his recovery tanks in ice; do I need to do this too?
A: Chilling the recovery tank will speed up the recovery process by lowering the pressure in the recovery tank. It is not
required but can speed up the process, especially when working in hot climates. The internal cooling system built into
this machine also helps to lower the temperatures of the refrigerants.
Q: My recovery machine power button is flashing lights, what do the flashes mean?
A: Refer to the key near the on button for more information regarding the flash codes the recovery machine can display.
Refer to the user’s manual for additional information.
Q: I have heard A3 refrigerants are safe to release to the atmosphere, why would I recover it?
A: Commonly distributors will require you to turn in the recovered refrigerant to buy replacement A3. Recovery is
also a best practice as all refrigerants have oils in them, and the release of those oil vapors can be hazardous to
health if inhaled. Always recover refrigerants and properly dispose of them.
Q: What is your warranty for MalcoEdge recovery machine and vacuum pumps?
A: MalcoEdge Recovery Units and Vacuum pumps include a 1-year standard manufacturer’s warranty, the warranty
extends to a 3-year warranty if the product is registered by the end user at purchase. See Malco’s Website
(link to product registration page) for additional information.
Q: Do I need to flush and clean my equipment when switching between refrigerants?
A: Some refrigerants cannot be mixed as they use different lubricants. As a best practice, the pumps, hoses, manifolds, and other components need to be flushed using a cleaner to ensure they do not cross contaminate. We recommend flushing the system with ACE Powerflush between services.
