Page 4: Safety Precautions
1. Safety Precautions  Read the following “SAFETY PRECAUTIONS” carefully before installation of (Mono bloc) Air-to-Water Heatpump system (hereafter referred to as “Mono bloc unit”).  Electrical works and water installation works must be done by licensed electrician and licensed water system installer respectively.
Page 5 WARNING When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no electrical contact between equipment and building is allowed. Insulator must be installed in between. This installation may be subjected to building regulation approval applicable to respective country that may require to notify the local authority before installation.
Page 6: Precaution For Using R32 Refrigerant
2. Precaution for Using R32 Refrigerant  The basic installation work procedures are the same as conventional refrigerant (R410A, R22) models. However, pay careful attention to the following points: WARNING Since the working pressure is higher than that of refrigerant R22 models, some of the piping and installation and service tools are special.
Page 7 CAUTION Installation (Space)  Must comply with national gas regulations, state municipal rules and legislation. Notify relevant authorities in accordance with all applicable regulations.  Must ensure mechanical connections be accessible for maintenance purposes.  In cases that require mechanical ventilation, ventilation openings shall be kept clear of obstruction. ...
Page 8 CAUTION Repairs to sealed components  During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc.  If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
Page 9 CAUTION Decommissioning  Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.  It is recommended good practice that all refrigerants are recovered safely.  Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant.

Page 86: Installation And Servicing Air Conditioner Using R32
13. Installation and Servicing Air Conditioner using R32 13.1 About R32 Refrigerant For air conditioning refrigerants such as R410A, the refrigerants were collected back in order to prevent their air dissipation, to curbe the global warming impact, in case they were released into the atmosphere. In the “4th Environmental Basic Plan”, 80% reduction of greenhouse gas emissions by 2050 is required, and due to this requirement, further reduction in the emission of high greenhouse effect gas, such as CFCs, is required.
Page 87 2. Characteristic of Pressure As shown in Table 2, R32 does not have much difference in vapor pressure at the same refrigerant temperature comparing to R410A, but comparing to R22, it is higher at 1.6 times more. Thus, the same as in case of R410A, it is necessary to do installation and service using high-pressure tools and components.
Page 88: Refrigerant Piping Installation • Tools Used In Services
13.3 Refrigerant piping installation • Tools used in services 13.3.1 Required Tools R32 refrigerant air conditioners use the common parts as R410A air conditioners for two-way valves and three-way valves (diameters of service ports); thus, they maintain commonality in the maintenance of the compressive strength, the size of pipe flaring, and the size of flare nuts as R410A.
Page 89 3. Torque wrenches (diameters 1/2, 5/8) Manifold gauges / Charging hoses In order to strengthen the compressive strength, the diameters of wrenches change depending on the flare nut sizes.

Page 95 13.6.2 Process of refrigerant recovery 1. Connect the center charging hose of manifold gauge to the in-let side of recovery device. 2. Connect the valves of the discharge side of recovery device and liquid side of refrigerant cylinder with red hose (charging hose).
Page 96 13.6.3 Relocation 1. Removing the air conditioning unit a) Recovery of outdoor unit refrigerant by pumping down Press “forced cooling button” (as a general rule, since 1998 the name of cooling testing button is changed, and this name is unified within the air conditioning industry), and then you are able to start cooling operation in which the room temperature is low, and you can recover the refrigerant from the outdoor unit.
Page 97 13.6.6 Re-insertion of refrigerant in service When re-insertion is needed, follow the procedures to ensure the insertion of new refrigerant at correct amount. 1. Attach charging hose (blue) to the service port of the outdoor unit. 2. Attach charging hose (red) to the vacuum pump. Fully open the 2-way and 3-way valves. 3.
