Wipcool MRS10 user manual

The Wipcool MRS10 Refrigerant Charging Scale is used to weigh and monitor the amount of refrigerant during charging and recovery. The CHARGE and RECOVER modes control refrigerant flow through a solenoid valve once a target mass has been set.

The user manual is an integral part of the product. Please read this manual carefully and follow all instructions strictly.

Operation

Charging the batteries

  1. 01Connect a USB-C cable to the scale's charging port and a USB power source.
  2. 02Check the charging status on the charging indicator.

Preparing for charging

  1. 01After connecting the cylinder and hoses, check that all connections are correct and leak-tight.
  2. 02Switch on the scale and wait for the reading to stabilise. The display will show the combined mass of the cylinder and refrigerant.

Then select either manual charging or charging in CHARGE mode.

Manual charging

  1. 01Briefly press ZERO to zero the reading.
  2. 02Charge the system by adjusting the valve on the charging hose and watching the scale reading.
  3. 03Once the required amount of refrigerant has been transferred, finish work as described in ‘Finishing work’.

In CHARGE and RECOVER modes, the minimum target refrigerant mass is 50 g.

Charging in CHARGE mode

  1. 01Hold MENU for 3 s, then select CHARGE mode using MENU.
  2. 02Enter the target mass, e.g. 1 kg as shown on the screens below: select the digit position using ZERO and UNIT, and increase the digit using POWER.
  3. 03Open the valve on the charging hose and press CONFIRM to start the cycle. The solenoid valve will open and refrigerant will begin to flow.
  4. 04Once the target amount of refrigerant has been transferred, the solenoid valve will close automatically. The display will show the combined mass of the cylinder and the refrigerant remaining in it.
  5. 05Finish work as described in ‘Finishing work’.

Finishing work

After charging:

  1. 01Close the valve on the charging hose. If using an upright cylinder, also close the cylinder valve.
  2. 02Disconnect the charging hose from the system and switch off the scale.

After recovery, close the system valves and switch off the scale.

Waste electrical and electronic equipment

  1. 01The crossed-out wheeled bin symbol means that the device must not be disposed of with other waste at the end of its life.

Under applicable regulations on waste electrical and electronic equipment, products marked with the separate collection symbol must not be disposed of with other municipal waste. Because they contain harmful substances, electronic products that are not collected separately may pose a risk to the environment and human health. Proper separate collection of waste electrical and electronic equipment prevents adverse effects on the environment.

By taking waste equipment to a collection point, the user contributes to its reuse, recycling and recovery.

Recycling - one method of protecting the environment. The process of recovering substances from waste that can be reused as raw materials.

Recovery - the use (also commonly understood as destruction) of waste that has lost its useful value, such as plastics, paper and cardboard, as secondary raw materials.

Information on the collection system for waste electrical and electronic equipment

  • ■Waste electrical and electronic equipment must not be disposed of with other waste.
  • ■The collection of incomplete electrical and electronic equipment and parts from waste equipment is prohibited.
  • ■A distributor delivering household equipment to a purchaser must collect waste household equipment free of charge at the place of delivery, provided that the waste equipment is of the same type and performs the same function as the equipment delivered.
  • ■The user may hand over waste equipment to a waste equipment collector, a treatment facility or a municipal waste collector in the municipality.
  • ■Information on collection points is available on the BIP websites of regional authorities and city and municipal offices.
16

Batteries and rechargeable batteries

  1. 01The crossed-out wheeled bin symbol on a battery or rechargeable battery means that it must be collected separately from other waste at the end of its life. It must not be disposed of with municipal waste.
  • ■Take used batteries and rechargeable batteries to a collection point. If possible, remove them from the device before taking it for collection.
  • ■Substances in batteries can harm the environment and health, especially if a battery is damaged or leaking. Separate collection allows them to be processed safely and raw materials to be recovered.
  • ■The marking Cd or Pb below the bin symbol means that the battery contains more than 0.002% cadmium or more than 0.004% lead.
