Page 21: Installation Considerations
Water Heat Exchanger Unit 6. Installation considerations Safety precautions Safety precautions Carefully read the following “Safety Precautions” before beginning installation and wiring work. The precautions in this document consist of specifi c Warnings and Cautions. All concern safety- related issues that require careful attention. Their meanings are as described below. - Page 22 Water Heat Exchanger Unit 6. Installation considerations Caution When handling refrigerant gas, do not directly touch the gas. This can cause burns due to freezing. Do not install the water heat exchanger unit where fl ammable gas could fl ow, accumulate or be produced, or where volatile or fl...
- Page 23 Water Heat Exchanger Unit 6. Installation considerations (2) Installation location Caution 1. Provide the required space for inspection and maintenance (see Figure 2). Insuffi cient space at the installation location could result in accidents from falling equipment. 2. If the water heat exchanger unit is installed on a roof or other high location, provide a permanent ladder or hand grips for safe access, and provide railings or hand grips around the water heat exchanger unit to prevent falls.
- Page 24 Water Heat Exchanger Unit 6. Installation considerations (3) Installing refrigerant piping and charging with refrigerant Caution Always replace the refrigerant with nitrogen before brazing refrigerant piping. Loose oxide scales can cause motorized valves to seize and clog strainers, which can result in operation failure.
- Page 25 Water Heat Exchanger Unit 6. Installation considerations (4) Water piping construction Warning Use only water as the heat-transfer medium for the hot/cold water circuits and the coolant circuits. Use of other fl uids could result in fi re or explosion. Caution Use hot/cold water and coolants that complies with refrigeration and air-conditioning equipment water quality guidelines (JRA-GL 02-1994)*.

- Page 27 Water Heat Exchanger Unit 6. Installation considerations 9. Provide suffi cient insulation on the water pipes. Heat loss due to insuffi cient insulation can result in damage from frozen pipes during severe cold periods. 10. The water heat exchanger unit includes a circuit to automatically start the hot/cold water circulation pump when the external air temperature and the temperature of the water within the unit fall, to prevent freezing within the water heat exchanger unit.
- Page 28 Water Heat Exchanger Unit 6. Installation considerations (7) Using Anti-Vibration Mounts Rooftop installations should include anti-vibration mounts in cases where noise or vibration may cause problems for residential and meeting rooms beneath. When using anti-vibration mounts, consider installing anti-vibration fi ttings on the refrigerant and other pipes. Also consider the following during installation.
