Page 4: Safety Precautions
1. Safety Precautions  Read the following “SAFETY PRECAUTIONS” carefully before installation of Air-To-Water Hydromodule + Tank (here after referred to as “Tank Unit”).  Electrical works and water installation works must be done by licensed electrician and licensed water system installer respectively.
Page 5 WARNING 17. Wire routing must be properly arranged so that control board cover is ﬁxed properly. If control board cover is not ﬁxed perfectly, it will cause ﬁre or electrical shock. 18. For electrical work, follow the national regulation, legislation and this installation instructions. An independent circuit and single outlet must be used.
Page 6 CAUTION 1. Do not install the Tank Unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fire. 2. Do not install the outdoor unit at place where leakage of ﬂammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause ﬁre.
Page 7: 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 When connecting flare at indoor side, make sure that the flare connection is used only once, if torqued up and released, the flare must be remade.
Page 8 CAUTION Installation (Space)  Must ensure the installation of pipe-work shall be kept to a minimum. Avoid use dented pipe and do not allow acute bending.  Must ensure that pipe-work shall be protected from physical damage.  Must comply with national gas regulations, state municipal rules and legislation. Notify relevant authorities in accordance with all applicable regulations.
Page 9 CAUTION 2-7. Checks to the refrigerating equipment  Where electrical components are being changed, they shall be fit for the purpose and to the correct specification.  At all times the manufacturer’s maintenance and service guidelines shall be followed.  If in doubt consult the manufacturer’s technical department for assistance.
Page 10 CAUTION The following leak detection methods are deemed acceptable for all refrigerant systems.  No leaks shall be detected when using detection equipment with a sensitivity of 5 grams per year of refrigerant or better under a pressure of at least 0,25 times the maximum allowable pressure (>1.04MPa, max 4.15MPa). For example, a universal sniffer.
Page 11 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 recovered refrigerant.

13. Installation and Servicing Heat Pump using R32 13.1 About R32 Refrigerant For heat pump 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 137 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.
