Resumen del manual
1 — Dimensions, Electronic and Mechanical Air Cleaners GENERAL The Carrier 31MP plate-type and 31 MM media-type electronic air cleaners and the 31MC high-efficiency mechanical air filters, all shown in Fig. 1, are designed for use with residential and light commercial forced-air heating and/or cooling systems. They can be installed vertically or horizontal^ in- the ductwork .of at the furnace. The units are easily converted in the field from right to left hand by removing the air cleaning components and reassembling them in reverse order. Cabinets will support a weight of 400 lb when installed beneath a vertical furnace or air-handling unit. Package Contents — The 31MP and 31 MM electronic air cleaner packages and the 31MC high-efficiency filter package consist of: 1. One 3 IMP, 31MM or 31MC unit. 2. Two base angle air baffles. 3. A template for preparing the furnace opening. 4. A bag of hardware consisting of 6 no. 8B x 1/4-in. long screws, 6 no. 8 speed nuts and a small bag containing wire nuts for making electrical connections. 5. A coil of foam tape. 6. Package of replacement media (31MM Models only). 7. An installer’s packet. When unpacking the unit, if any in-transit damage is observed, file a claim with the transportation agency. Since the air cleaner components are packed in a single carton, be sure to inspect all packing materials before discarding. Application — Install the electronic air cleaner where all of the air circulated by the system will pass thru it. The best location is in the return air duct close to the blower compartment. This location provides the most even air flow distribution across the face of the electronic cells or mechanical filter element and also allows the air cleaner to keep the blower and motor clean. In a cooling system, the air cleaner keeps the evaporator coil clean. When it is not possible or economically feasible to mount the air cleaner in the return air duct, consider installing the unit in the air discharge duct. However, give special consideration to the following factors when planning such an installation. 1. Even air flow distribution across the face of the electronic cells may be difficult to achieve. Use turning vanes and transitions where necessary. 2. Put the air cleaner upstream from the coil in a cooling system, if possible. The electronic air cleaner or mechanical filter will help keep the © Carrier Corporation 1975 Form 31MP-2SI coil clean, reducing maintenance costs. Also, air coming from the coil will frequently be near 100% relative humidity. 3. The air flow temperature thru the air cleaner must be within 40 F to 125 F. Location — Because air-handling systems vary greatly in arrangement and style, factors such as accessibility, ambient temperature ratings, transitions, and other requirements must be carefully considered. In crawl space or attic installations (unconditioned space), air cleaner must be insulated the same as ductwork. The unit must be readily accessible for periodic inspection and cleaning of the prefilter and electronic cells to maintain maximum efficiency and trouble-free operation. A minimum of 30 in. of clear area should be left in front of the air cleaner for cell and prefilter removal. The air cleaner must be installed where the temperature will be within a 40 F to 125 F range. Humidifiers — Location of the system humidifier is important to the operation of the electronic air cleaner or mechanical filter. When an evaporative-type humidifier is used, it may be installed between the furnace warm air duct and the return air duct without affecting the electronic air cleaner. An atomizing-type humidifier must be installed downstream from the air cleaner. If the atomizing-type humidifier is installed upstream, high humidity, salts and minerals will decrease the efficiency of the electronic cell and cause service problems or damage the high-efficiency filter element in the mechanical air filter. Outdoor Air — When outdoor air is added to the return air duct, sufficient heat must be added to maintain the return air temperature at 40 F minimum. Lower temperatures can cause ionizer wire failure under certain conditions. Two methods are recommended: 1. Mixing baffles or vanes. When outdoor air is added, make certain that it is far enough ahead of the air cleaner to be mixed and warmed properly. If not, ba...
