BUILDING DIVISION _ C , j! The 38MGR ductless inverter driven multi—zone system provides s ill%� individual comfort control for up to 5 separate zones.Two,three, .��, �=�� four or five space—saving High Wall, Cassette, Slim Ducted or .._,° Floor Console fan coils can be matched with one outdoor heat i pump. The indoor fan coils are connected to the outdoor unit by refrigerant tubing and wires. Fig.1— 18K The different styles of indoor units can be mounted in several locations to accommodate the application. This selection of fan coils permits inexpensive and creative solutions to design problems such as: = ';- - Caner • When adding air conditioning to spaces that are heated by IIIr \� ri;. �%- ' `�1 hydronic or electric heat and have no ductwork. fl� r a, r, r+,', n<<f ,wic • Historical renovations or any application where preserving the 1 'sllaf�ll(' , �!! iit look of the original structure is essential.

A mounting power frequencies (Hz) which controls the compressor's motor bracket is included with the indoor units and only wires and piping speed. need to run between the indoor and outdoor units.These units are Even Temperature—The control package,including the inverter, fast and easy to install ensuring minimal disruption to customers in monitors the outdoor and indoor temperatures as they relate to the homes or the workplace. This makes the 38MGR systems the selected indoor set point and adjusts the compressor speed to match equipment of choice for retrofit applications. the load and keep the system operating continuously rather than Simple Servicing and Maintenance cycling and creating temperature swings.This translates to higher Removing the top panel of the outdoor unit provides immediate comfort levels for the occupants. access to the control compartment,providing the service technician Rapid Pull Down/Warm—Up — Comfort is increased by the access to the diagnostic LEDs to facilitate the troubleshooting inverter system's ability to ramp up the compressor speed enabling process. In addition, the draw—thru design of the outdoor unit the system to reach the user selected room temperature set point means that dirt accumulates on the outside surface of the coil.Coils quicker. can be cleaned quickly from the inside using a pressure hose and Humidity Control—Running the system for longer periods and detergent. continuously varying the compressor speed enhances the humidity On the indoor units, service and maintenance expense is reduced control. due to the permanent easy to clean filters. Also, error codes are Individual Room Comfort displayed on the front panel to alert the user to certain system Maximum comfort is provided because each space can be malfunctions controlled individually based on the usage pattern. Built—in Reliability Low Sound Levels Ductless system indoor and outdoor units are designed to provide When noise is a concern, ductless systems are the answer. The years of trouble free operation. indoor units are whisper quiet.There are no compressors indoors, Both the indoor and outdoor units are well protected.Whenever either in the conditioned space or directly over it,and there is none the microprocessor detects abnormal conditions,the unit stops and of the noise usually generated by air being forced through the an error code appears. ductwork. Inverter systems provide additional reliability due to the soft start. When sound ordinances and proximity to neighbors demand quiet This refers to the ability of the inverter to start the compressor operation,the 38MGR unit is the right choice. With the inverter motor using reduced voltage and reduced current. This feature is technology, these units run at lower speeds most of the time beneficial from an electrical standpoint(eliminates current spikes) resulting in reduced sound levels. as well as an overall reliability standpoint due to reduced stress on Inverter Technology—Enhanced Economical all associated system components. Operation Agency Listings Ductless systems are inherently economical to operate.Individual All systems are listed with AHRI(Air conditioning,Heating,and rooms are heated or cooled only when required,and since the air is Refrigeration Institute) and are ETL certified per UL 1995 delivered directly to the space, there is no need to use additional standard. energy to move the air in the ductwork.This economical operation is enhanced further when the inverter system output matches the load resulting in a more efficient system. Easy—To—Use Controls The multi—zone systems have microprocessor—based controls to provide the ultimate in comfort and efficiency. The user friendly wired and wireless remote controls provide the interface between the user and the unit. Secure Operation If security is an issue,outdoor and indoor units are connected only by refrigerant piping and wiring to prevent intruders from crawling through ductwork or wall openings.In addition,since the 38MGR can be installed close to an outside wall, coils are protected from vandals and severe weather. 2 MODEL NUMBER NOMENCLATURE OUTDOOR UNIT 38 MG R Q 18 B - - 3 38=OUTDOOR UNIT MG=ALL VOLTAGE 3=208/230-1-60 UNIT TYPE R=OUTDOOR UNIT SYSTEM TYPE NOT USED Q=HEAT PUMP NOMINAL CAPACITY MAXIMUM NUMBER OF FAN COIL UNITS THAT 18—1 1/2 TONS CAN BE CONNECTED TO THE OUTDOOR UNIT 24—2 TONS _ 30-21/2TONS B-1.2 36—3 TONS C=1:3 48-4TONS D=1:4 E=1:5 A V�/ tN4ERtet A !R CERTIFIED,.

Failure to follow this caution may result in equipment Refrigerant Lines damage or improper operation. General Guidelines: Wires should be sized based on NEC and local codes. 1. The outdoor units are shipped with a full charge of R-410A refrigerant.All charges,line sizing,and capacities are based on runs of 25 ft. (7.6 m). For runs over 25 ft. (7.6m), consult long—line section on this page for proper charge adjustments. 2. Refrigerant lines should not be buried in the ground. If it is CAUTION necessary to bury the lines, do not bury more than 36 inches (914 mm). Provide a minimum of 6 inch (152 mm) vertical rise to the service valves to prevent refrigerant migration. EQUIPMENT DAMAGE HAZARD 3. Both lines must be insulated. Use a minimum of 1/2—inch Failure to follow this caution may result in equipment damage (12.7 mm) thick insulation.
