R-32 SEALED SYSTEM REPAIRS

Refrigerant Charging

NOTE: Always weigh in refrigerant based on the model nameplate.

Warning:

• Ensure that contamination of different refrigerants does not occur when using charging equipment.

• Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them.

• Cylinders shall be kept in an appropriate position according to the instructions.

• Ensure that the REFRIGERATING SYSTEM is grounded prior to charging the system with refrigerant.

• Label the system when charging is complete (if not already).

• Extreme care shall be taken not to overﬁll the REFRIGERATING SYSTEM.

• Prior to recharging a system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-tested on completion of

charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

•

NOTE: Because the refrigerant system is a sealed system, service process tubes will have to be installed. First install a line tap and remove refrigerant

from system. Refer to the Refrigerant removal section of this manual for procedures. Make necessary sealed system repairs and vacuum system.

The acceptable method for charging the sealed system is the Weighed in Charge Method. The weighed in charge method is applicable to all units. It is

the preferred method to use, as it is the most accurate.

The weighed in method should always be used whenever a charge is removed from a unit such as for a leak repair, compressor replacement, or when

there is no refrigerant charge left in the unit. To charge by this method, requires the following steps:

WARNING: Electrical Shock Hazard

Disconnect all power to the unit before starting maintenance. All electrical connections and wiring MUST be installed by a qualiﬁed electrician

and conform to all codes which have jurisdiction. Failure to do so can result in property damage, severe electrical shock or death.

WARNING: This Product uses R-32 Refrigerant

Do not use means to accelerate the defrosting process or to clean, other than those recommended by the

manufacturer.

When not installed, the appliance shall be stored in a room without continuously operating ignition

sources (for example: open ﬂames, an operating gas appliance or an operating electric heater.

Do not pierce or burn.

Be aware that refrigerants may not contain an odor.

WARNING:

Refrigeration System under High pressure

Do not puncture, heat, expose to ﬂame or incinerate. Only certiﬁed refrigeration technicians should service this equipment. R32 systems

operate at higher pressures than R22 equipment. Appropriate safe service and handling practices must be used.

WARNING:

Freeze Hazard

Proper safety procedures must be followed, and all PPE must be utilized when working with liquid refrigerant. Failure to

comply could result in minor to moderate injury.
