Resumen del manual
Only trained, qualified installers and service mechanicsshould install, start up, and service this equipment. When working on this equipment, observe precautions inthe literature, and on tags, stickers, and labels attached to theequipment, and any other safety precautions that apply. Followall safety codes. Wear safety glasses and work gloves. Usecare in handling, rigging, and setting this equipment, and inhandling all electrical components. WARNING Electrical shock can cause personal injury and death. Shutoff all power to this equipment during installation. Theremay be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until workis completed. WARNING DO NOT VENT refrigerant relief valves within a building. Outlet from relief valves must be vented outdoors in accordance with the latest edition of ANSI/ASHRAE(American National Standards Institute/American Societyof Heating, Refrigerating and Air Conditioning Engineers) 15 (Safety Code for Mechanical Refrigeration). Theaccumulation of refrigerant in an enclosed space candisplace oxygen and cause asphyxiation. Provide adequateventilation in enclosed or low overhead areas. Inhalation of high concentrations of vapor is harmful and may causeheart irregularities, unconsciousness or death. Misuse canbe fatal. Vapor is heavier than air and reduces the amountof oxygen available for breathing. Product causes eye andskin irritation. Decomposition products are hazardous. WARNING DO NOT attempt to unbraze factory joints when servicingthis equipment. Compressor oil is flammable and there isno way to detect how much oil may be in any of therefrigerant lines. Cut lines with a tubing cutter as requiredwhen performing service. Use a pan to catch any oil thatmay come out of the lines and as a gage for how much oilto add to system. DO NOT re-use compressor oil. Damageto equipment or personal injury may result. CAUTION This unit uses a microprocessor-based electronic controlsystem. Do not use jumpers or other tools to short outcomponents, or to bypass or otherwise depart from recommended procedures. Any short-to-ground of the controlboard or accompanying wiring may destroy the electronicmodules or electrical components. CAUTION To prevent potential damage to heat exchanger, always runfluid through heat exchanger when adding or removingrefrigerant charge. Use appropriate brine solutions in coolerfluid loop to prevent the freezing of brazed plate heatexchanger when the equipment is exposed to temperaturesbelow 32 F (0° C). Proof of flow switch is factory installedon all models. Do NOT remove power from this chiller during winter shutdown periods without taking precaution toremove all water from heat exchanger and optionalhydronic system. Failure to properly protect the systemfrom freezing may constitute abuse and may void warranty. CAUTION Compressors require specific rotation. Monitor controlalarms during first compressor start up for reverse rotationprotection. Damage to unit may result. CAUTION Refrigerant charge must be removed slowly to prevent lossof compressor oil that could result in compressor failure. CAUTION Puron® refrigerant (R-410A) systems operate at higherpressures than standard R-22 systems. Do not use R-22 service equipment or components on Puron refrigerant equipment. If service equipment is not rated for Puron refrigerant, equipment damage or personal injury mayresult. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Catalog No. 04-53300053-01 Printed in U.S.A.
