036-21126-002-D-1102 TECHNICAL GUIDE CMMERCIAL SPLIT-SYSTEM HEAT PUMP FUR PIPE SYSTEM E*FB180 & 240 F*EH180 & 240 15 & 20 NMINAL TNS DESCRIPTIN Both the outdoor and indoor units are completely piped and wired at the factory and are shipped ready for immediate installation. nly the blower motor and drive package (F*EH240 NLY) interconnecting liquid and suction lines, sight glasses, control wiring, and the main power wiring are required to complete the installation. Every unit is dehydrated, evacuated, leak tested and pressure tested at 450 psig before being pressurized with a holding charge of Refrigerant- 22 for shipment and/or storage. To eliminate the costly cabinet deterioration problems usually associated with outdoor equipment, all sheet metal parts are constructed of commercial grade (G90) galvanized steel. After fabrication, each part is thoroughly cleaned to remove any grease or dirt from its surfaces. The parts that will be exposed to the weather are then coated with a "Desert Sand" powder paint to assure a quality finish for many years. This coating system has passed the 750-hour, salt spray test per ASTM Standard B117. UTDR UNIT Every unit includes two heavy-duty scroll compressors, two suction line accumulators, two 4- way reversing valves with a 24 volt solenoid, two outdoor fan motors with inherent protection, and a copper tube/aluminum fin coil that is positioned vertically for better drainage of the water that will condense on it during the heating cycle. They also include two filter driers, two expansion valves and distributors that are only used during the heating cycle plus a check valve to provide the proper flow of refrigerant through the unit during both the cooling and heating cycles. All controls are located in the front of the unit and are readily accessible for maintenance, adjustment and service. All wiring (Power and Control) can be made through the front of the unit. INDR UNIT Every unit includes a well-insulated cabinet, copper tube/aluminum fin coil with interlaced circuitry arrangement, one-inch throwaway filters, centrifugal blower with a fixed pitch sheave, and a blower motor with variable pitch sheave.

INDR UNIT Every unit includes a well-insulated cabinet, copper tube/aluminum fin coil with interlaced circuitry arrangement, one-inch throwaway filters, centrifugal blower with a fixed pitch sheave, and a blower motor with variable pitch sheave. They also include two filter driers, two expansion valves and distributors that are only used during the cooling cycle, plus, a check valve to provide the proper flow of refrigerant through the unit during both the cooling and heating cycles. The controls include 208/230/460 volt transformer, blower motor contactor and relay, and a low voltage terminal block. The units are shipped in the vertical position ready for field installation. For horizontal installation, the blower module can be repositioned in the field as shown on page 3 for maximum flexibility. ACCESSRIES (FIELD INSTALLED) Three-Phase Electric Heaters are available in several capacities to provide maximum flexibility. The heater can be selected to precisely meet the supplemental heating requirement of the conditioned space. These heaters are designed for easy field-installation over the supply air opening(s) of the indoor unit. They have been tested by Underwriters Laboratories and will be shipped with a UL label. Every heater will be fully protected against excessive current and temperature by fuses and two high limit thermostats. Units with Electric Heat will require only one power supply for both the heating elements and the supply air blower motor, and the power wiring can be protected by either dual element/time delay fuses or an inverse time circuit breaker. NTE: n F*EH, a 2HB & 2HC model heater will be required. Supply Air Plenums and Return Air Grilles (expanded metal) are available for free-standing indoor units located in the conditioned space. Both accessories are finished to match the exterior of the basic unit, and both can be applied with either vertical or horizontal units. The supply air plenums are fully insulated and have double-deflection, adjustable grilles. Base Sections are available to raise vertical indoor units above the floor. utdoor air may be introduced through these bases by cutting an access opening for the outdoor air duct connection. These bases are finished to match the exterior of the basic unit. They may have to be insulated in the field for certain applications. Suspension Kit is available for indoor units installed horizontally. Thermostats with either manual or automatic changeover are available for precise control of the temperature within the conditioned space. The manual thermostat has a four-position selector switch - CL, FF, HEAT, and EMERGENCY HEAT, and three stages of control - one stage of cooling and two stages of heating. The automatic thermostat has a three-position selector switch - FF, AUTMATIC and EMER- GENCY HEAT, and four stages of control - two stages of cooling and two stages of heating. Both thermostats have a two-position fan switch, AUT and N to provide intermittent or continuous blower operation. NTE: The automatic changeover thermostat must be used on units equipped with a field-supplied economizer. The first cooling stage of the automatic thermostat will only control the position of the reversing valve; the system will still operate with only one stage of cooling. The EMERGENCY HEAT position on the selector switch and the second stage of heating will only function on systems with an electric heat accessory. APPLICATIN FLEXIBILITY FIGURE 1 - UTDR UNITS E*FB180 & 240 The outdoor units are lightweight and can be installed on almost any roof. Unitary Products Group 3
Units can be lifted using nylon straps with hooks at the holes provided in the base rails, or they may be lifted with a forklift through the slotted openings in the base rails. A quality appearance and low sound levels make these units suitable for most ground level locations. Remember that during heat and defrost cycles, condensate will drip from the underside of the unit coils and that this condensate will freeze when the temperature of the outdoor air is below 32 F. A gravel bed or some other means of handling this condensate may have to be provided. The indoor units are built in a single cabinet with one condensate drain pan. These units can be installed in either the vertical or horizontal position for maximum flexibility. n vertical applications, the air velocity across the indoor coil keeps the condensate from dripping off the finned surface onto the filters. n horizontal applications, the unit must be installed with the condensate drain pan under the entire indoor coil. The Supply Air Plenum and the Return Air Grille accessories can be used on either arrangement. The Base accessory can only be used on the vertical arrangement. Certain blower positions are not recommended because the blower motor should not be mounted upside down. Models 180 and 240 This unit has two distinct modules; a blower module and a coil module. Although the unit is always shipped in the vertical position with a vertical air discharge as show in illustration (a); the blower module can be repositioned in the field as shown in illustrations (b) and (c) for maximum flexibilitiy. The Supply Air Plenum, Return Air Grille and Base Accessories can be applied on arrangement (a). The Return Air Grille and Base Accessories can be applied on arrangement (b). The Supply Air Plenum, Return Air Grille and Suspension Accessories can be applied on arrangement (c). FIGURE 2 - HRIZNTAL AND VERTICAL PSITIN 4 Unitary Products Group

These ratings are based on an outdoor relative humidity of 72%. They include an allowance for defrost but not for the supply air blower motor heat. Refer to the BLWER PERFRMANCE tables for the kw rating of the supply air blower motor at the design conditions. Convert this kw rating to MBH using the following equation and add this equivalent heat to the heating capacity: BLWER MTR HEAT (MBH) = BLWR MTR kw X 3.413.
