FAQs
Q1: Should a filter drier be used on the inlet side of my recovery machine?
A1: Yes. Installing a filter drier prior to the recovery machine prevents non-condensables from entering it. We recommend using a new filter drier for every recovery.
Q2: Can I draw down a system prior to charging with the MalcoEdge Velo-X Recovery Machine?
A2: No. The MalcoEdge Velo-X Recovery Machine is designed to recover refrigerant. A vacuum pump should be used to draw a deep vacuum or run a decay test.
Q3: How do microns compare to PSI?
A3: 1 micron of mercury equals 0.000019337 PSIG. For reference, if you get under 500 microns you are dealing with a deep vacuum.
Q4: What are the differences between a recovery machine and a vacuum pump?
A4: A MalcoEdge Recovery Machine removes liquid refrigerants, moisture, and vapor from a system that has previously been charged prior to service. It does not typically draw a system into a deep vacuum. A MalcoEdge Vacuum Pump, on the other hand, removes any remaining vapor and draws the system down into a deep vacuum. A vacuum pump is also used to perform a decay test.
Q5: How fast will a MalcoEdge Recovery Machine remove refrigerant?
A5: The MalcoEdge 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.
Q6: Is the MalcoEdge Recovery Machine AC or DC?
A6: The MalcoEdge Recovery Machine is powered by AC, but uses a variable speed DC motor that can ramp up or down when working with liquid or gaseous refrigerants.
Q7: When should I use a MalcoEdge Recovery Machine?
A7: 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 and pumped into a recovery tank. Once removed, a technician may then service the system.
Q8: Do I need to change any settings when the machine switches from liquid to vapor recovery?
A8: No. There are no settings to switch when using the MalcoEdge VeloX Pump — it handles the transition automatically.
Q9: What is the silver knob at the front of my MalcoEdge Recovery Machine?
A9: The silver component is an attachment point for a shoulder carry strap, which is included with the MalcoEdge Recovery Machine.
Q10: Does the MalcoEdge Recovery Machine require oil?
A10: No. MalcoEdge recovery units do not require oil.
Q11: Does the MalcoEdge Recovery Machine turn off when it reaches a certain vacuum level?
A11: Yes. The MalcoEdge Recovery Machine automatically shuts off once it has drawn the system down to 10 inHg.
Q12: My MalcoEdge Recovery Machine is showing a high pressure shut off code. What does this mean?
A12: This code indicates the recovery tank is full. The MalcoEdge Recovery Machine will automatically stop filling a recovery tank when it reaches 550 PSIG.
Q13: A technician I know places recovery tanks in ice — do I need to do this too?
A13: It’s not required, but chilling the recovery tank can speed up the process by lowering the pressure inside the tank — especially helpful in hot climates. The internal cooling system built into this machine also helps lower refrigerant temperatures.
Q14: My recovery machine power button is flashing — what do the flashes mean?
A14: Refer to the key near the power button for information on flash codes. See the user’s manual for additional detail.
Q15: I’ve heard A3 refrigerants are safe to release to the atmosphere — why would I recover it?
A15: Distributors commonly require you to turn in recovered refrigerant to purchase replacement A3. Recovery is also best practice, as all refrigerants contain oils whose vapors can be hazardous if inhaled. Always recover refrigerants and dispose of them properly.
Q16: What is the warranty for MalcoEdge recovery machines and vacuum pumps?
A16: MalcoEdge Recovery Units and Vacuum Pumps include a 1-year standard manufacturer’s warranty, which extends to a 3-year warranty if the product is registered by the end user at the time of purchase. See Malco’s website for additional information and to register your product.
Q17: Do I need to flush and clean my equipment when switching between refrigerants?
A17: Yes. Some refrigerants use different lubricants and cannot be mixed. As a best practice, flush pumps, hoses, manifolds, and other components between services to prevent cross-contamination. We recommend using ACE Powerflush when switching refrigerants.
