Back Cover Rev. A 1-2-02 P/N 472032 3 MiniMax NT Standard Pool and Spa Heaters Congratulations on your purchase of a MiniMax NT Standard high performance heating system. Proper installation and service of your new heating system and correct chemical maintenance of the water will ensure years of enjoyment. The MiniMax NT Standard is a compact, lightweight, efficient, induced-draft, gas fired high performance pool and spa heater that can be directly connected to schedule 40 PVC pipe. The MiniMax NT Standard also comes equipped with the Pentair multifunction 7800 temperature controller which shows, at a glance, the proper functioning of the heater. All HSI (hot-surface ignition) MiniMax NT Standard heaters are designed with a direct ignition device (HSI) which eliminates the need for a standing pilot. The MiniMax NT Standard requires an external power source (120/240 VAC 50/60 Hz) to operate. IMPORTANT NOTICES ...For the installer and operator of the MiniMax NT Standard pool and spa heater. The manufacturer’s warranty may be void if, for any reason, the heater is improperly installed and/or operated. Be sure to follow the instructions set forth in this manual. If you need any more information, or if you have any questions regarding to this pool heater, please contact Pentair Pool Products, Inc. at (800) 831-7133. These heaters are designed for the heating of swimming pools and spas, and should never be employed for use as space heating boilers, general purpose water heaters, in non-stationary installations, or for the heating of salt water. Do not use the heater to protect pools or spas from freezing if the final maintenance temperature desired is below 60° F. as this will cause condensation related problems. CODE REQUIREMENTS The installation must conform with local codes or in the absence of local codes with the latest National Fuel Gas Code, ANSI Z223.1, and the latest edition of the National Electrical Code, NFPA 70. Installation in Canada to be made in accordance with the latest CAN/CGA-B149.1 or .2 and CSA C22.1 Canadian Electric Code, part 1. Introduction P/N 472032 Rev. A 1-2-02 4 Operation This instruction manual provides operating instructions, installation and service information for the MiniMax NT Standard high performance heater. The information in this manual applies to the MiniMax NT Standard 200, 250, 300, and 400 models. It is very important that the owner/installer read and understand the section covering installation instructions, and recognize the local and state codes before installing the MiniMax NT Standard. History and experience has shown that most heater damage is caused by improper installation practices. SAFETY RULES 1. Spa or hot tub water temperatures should never exceed 104° F. A temperature of 100° F. is considered safe for a healthy adult. Special caution is suggested for young children. 2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning. 3. Pregnant women beware! Soaking in water above 100° F. can cause fetal damage during the first three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick to the 100° F. maximum rule. 4. Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer. Spa or hot tub thermostats may err in regulating water temperatures by as much as 4° F. 5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their physician's advice before using spas or hot tubs. 6. Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use spas or hot tubs. Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance. Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to replace any part of control system and gas control which has been under water.
