8. Removal and evacuation
• When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used.
However, it is important that best practice is followed since flammability is a consideration.
The following procedure shall be adhered to:
• remove refrigerant -> • purge the circuit with inert gas -> • evacuate -> • purge with inert gas -> • open the circuit by cutting or brazing
• The refrigerant charge shall be recovered into the correct recovery cylinders.
• The system shall be purged with OFN to render the appliances safe. (remark: OFN = oxygen free nitrogen, type of inert gas)
• This process may need to be repeated several times.
• Compressed air or oxygen shall not be used for this task.
• Purging shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum.
• This process shall be repeated until no refrigerant is within the system.
• When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place.
• This operation is absolutely vital if brazing operations on the pipe work are to take place.
• Ensure that the outlet for the vacuum pump is not close to any potential ignition sources and there is ventilation available.
9. Charging procedures
• In addition to conventional charging procedures, the following requirements shall be followed.
- Ensure that contamination of different refrigerants does not occur when using charging equipment.
- Hoses or lines shall be as short as possible to minimize 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 earthed prior to charging the system with refrigerant.
- Label the system when charging is complete (if not already).
- Extreme care shall be taken not to over fill the refrigerating system.
• Prior to recharging the system it shall be pressure tested with OFN (refer to #7).
• 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.
• Electrostatic charge may accumulate and create a hazardous condition when charging and discharging the refrigerant.

i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been filled correctly and the process completed, make sure that the
cylinders and the equipment are removed from site promptly and all isolation valves on the equipment
are closed off.
k) Recovered refrigerant shall not be charged into another refrigerating system unless it has been
cleaned and checked.
• mechanical handling equipment is available, if required, for handling refrigerant cylinders;
• all personal protective equipment is available and being used correctly;
• the recovery process is supervised at all times by a competent person;
• recovery equipment and cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various
parts of the system.
• Electrostatic charge may accumulate and create a hazardous condition when charging or discharging the refrigerant.
To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before charging/discharging.
11. Labelling
• Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant.
• The label shall be dated and signed.
• Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
12. Recovery
• When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.
• When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed.
• Ensure that the correct number of cylinders for holding the total system charge are available.
• All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant).
• Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order.
• Recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
• The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants.

Typical Piping Installation
Please engage a licensed water circuit installer to install this water circuit.
• This water circuit must comply with relevant European and national regulations (including EN61770), and local building regulation codes.
• Ensure the components installed in the water circuit could withstand water pressure during operation.
• Do not apply excessive force to piping that may damage the pipes.
• Use Rp 1¼" nut for both water inlet and water outlet connection and clean all piping with tap water before connecting to the Mono bloc unit.
• Cover the pipe end to prevent dirt and dust when inserting it through a wall. If an existing tank is to be connected to this Mono bloc unit, ensure the pipes are clean before water pipe installation is carried out.
• Choose proper sealer which can withstand the pressures and temperatures of the system.
• Make sure to use two spanners to tighten the connection.Tighten the nuts with torque wrench: 117.6 N•m.
• If non-brass metallic piping is used for installation, make sure to insulate the piping to prevent galvanic corrosion.
• Do not use pipes that are crushed or deformed. If these inferior pipes are used, it may cause unit malfunction.
• Make sure to insulate the water circuit piping (insulator thickness : 20mm or more) to prevent condensation during cooling operation and reduction of heating capacity, as well as avoid freezing of the outdoor
water circuit piping during winter season.
• After installation, check the water leakage condition in connection area during test run.
• In case of a power supply failure or pump operating failure, drain the system (as suggested in the figure below).
H< H
When water is idle inside the system,
freezing up is very likely to happen
which could damage the system.
Drainage piping installation
• Use a drain hose with inner diameter of 15 mm.
• The hose must be installed in a continuously downward direction and left open to the frost-free atmosphere.
• If drain hose is long, use a metal support fixture along the way to eliminate the wavy pattern of drain tube.
• Water will drip from this hose, therefore the outlet of this hose must be installed in an area where the outlet cannot become blocked.
• Do not insert this hose into sewage or drain pipe that may generate ammonia gas, sulfuric gas, etc.
• If necessary, use a hose clamp to tighten the hose at drain hose connector to prevent it from leaking.
CAUTION
Do not over tighten, over tightening cause water leakage.
