i i HWE09120 GB Safety Precautions Before installing the unit, thoroughly read th e following safety pre cautions. Observe these safety precautions for your safety. W ARNING This symbol is intended to alert the user to the p resence of important instructions that must be followed to avoid the risk of serious injury or death.
ii HWE09120 GB W ARNING Securely attach the terminal block cover (pa nel) to the unit. If the terminal block cover (panel) is not installed properly, dust and/or water may infiltrate and pose a risk of electric shock, smoke, and/or fire. Only use the type of refrigerant that is indicated on the unit when inst alling or reinstalling th e unit.
iii iii HWE09120 GB Precautions for handling units for use with R410A CAUTION Do not use the existing refrigerant piping. A large amount of chlorine tha t may be contained in the re- sidual refrigerant and refrigerating machine oil in the exi st- ing piping may cau se the refrigerating machi ne oil in the new unit to deteriorate.
iv HWE09120 GB Before installing the unit W ARNING Do not install the unit where a gas leak may occur. If gaseous refrigerant leaks and piles up around the unit, it may be ignited. Do not use the unit to keep food items, anim als, plants, artifacts, or for other special purp oses.
v v HWE09120 GB Before installing the unit (moving and reinstalling the unit) and performing electrical work CAUTION Properly ground the un it. Do not connect the groundin g wire to a gas pipe, water pipe, lightning rod, or gro unding wire from a telephone pole.
vi HWE09120 GB Before the test run CAUTION Turn on the unit at least 12 hours before the test run. Keep the unit turned on throug hout the season. If the unit is turned off in the middle of a season, it may result in malfunc- tions. To avoid the risk of electric sh ock or malfunction of the unit, do not operate sw itches with w et hands.

[ I Read Before Servicing ] - 4 - HWE09120 GB [2] Necessary Tools and Materials Prepare the following tools and mate rials necessa ry for installing and servicing the unit. Tools for use with R410A (Adaptability of tools that are for use with R22 or R407C) 1.
[ I Read Before Servicing ] - 5 - HWE09120 GB [3] Piping Materials 1. Copper pipe ma terials The distinction between O-materials (Annea led) and 1/2H-materials (Drawn) is made based on the strength of the pipes them- selves. O-materials (Annealed) can easily be ben t with hands.
[ I Read Before Servicing ] - 6 - HWE09120 GB 4. Thickness and refrigerant type indicated on the piping materials Ask the pipe manufacturer for the symbols indicat ed on the piping material for new refri gerant.
[ I Read Before Servicing ] - 7 - HWE09120 GB [4] Storage of Piping 1. Storage location Store the pipes to be used indoors. (Warehouse at site or owner's ware house) If they are left outdoors, dust, dirt, or moisture may infi ltrate and contaminate the pipe.
[ I Read Before Servicing ] - 8 - HWE09120 GB [6] Brazing No changes have been made in the brazing procedures. Perform brazing with special care to keep foreign objects (such as oxide scale, water, and dust) out of the refrigerant system. Example: Inside the brazed connection 1.
[ I Read Before Servicing ] - 9 - HWE09120 GB [7] Air Tightness Test No changes have been made in the detection method. Note that a refrigerant leak detector for R22 wi ll not detect an R410 A leak. 1. Items to be strictly observed Pressurize the equipment with nitrogen up to the de sign pressure (4.
[ I Read Before Servicing ] - 10 - HWE09120 GB [8] Vacuum Drying (Ev acuation) 1. Vacuum pump with a r everse-flow check valve (Photo1) To prevent the vacuum pump oil from flowing into the refrigerant circuit du ring power OFF or power failure, use a vacuum pump with a reverse-flow check valve.
[ I Read Before Servicing ] - 11 - HWE09120 GB [9] Refrigerant Charging 1. Reasons R410A is a pseudo-azeotropic HFC blend (boilin g point R32=-52°C[-62°F], R125=-49°C[-52°F]) and ca n almost be handled the same way as a single refrigerant, such as R22.
[ I Read Before Servicing ] - 12 - HWE09120 GB [11] Characteristics of the Conventiona l and the New Refrigerants 1. Chemical property As with R22, the new refrigerant (R410A) is low in toxicity and chemically stable nonflammable refrigerant.
[ I Read Before Servicing ] - 13 - HWE09120 GB [12] Notes on Refrig erating Machine Oil 1. Refrigerating machine oil in the HFC refrigerant system HFC type refrigerants use a refrigerating machine oil different from that used in the R22 system.
