For the chilled water circuit, use only chilled water additive "N" (Bryant part number 68593C1). NOTE: When this chiller is used in conjunction with a boiler, a 4 -pipe system must be used. A common piping system cannot be used. Use separate coils and piping. GENERAL Model 36-453, Series C, is a gas-fired air-cooled absorption refrigeration system, suitable for residential or small commercial air conditioning system. The 453 absorption unit is used for cooling in conjunction with indoor or outdoor coil assemblies . The chiller can also be used with a Bryant gas-fired furnace to provide "allseasons" air conditioning for either warm or cool air, as outside temperatures dictate. brqant I 39453D48 Rev 1 5/20/70 Multiple Cl!i№eKS 1 u I When it is pi. or more chillers or doil/sf’’”-- J^iping and electrical informSîonTsr^^ttæêâ.^-nd should be obtained from your Bryant distributor. When making multiple chiller installations, only Model 36-453, Series C chillers can be interconnected. Do not manifold Series C units with Model 450, 451 or 452 units of any series, or with Model 453 Series A or Bunits . Operation at Atmospheric Pressure The chilled water tank on this unit is vented to the atmosphere; consequently, the chilled water circuit operates at atmospheric pressure. Therefore, conventional piping practices for a closed, pressurized system do not apply for this unit. =E? m === g <=z r_—' = = =a => =3 3 OPTIONAL GAS INLET HOLE\ * MPT CHILLED * WATER CONN S. rGAS INLET 36-453, Series C RATINGS, CAPACITIES AND COMPONENT INFORMATION Gas Input BTUH 85,000 Power Supply (Voltage, Cycles, Phase) 115-60-1 Electrical Input KW 1.2 Condenser Air Flow CFM 3,500 Refrigerant Type R 717 Amount Lbs 6.8 Total Solution Lbs 18.5 Factory Test Pressure (Refrigerant Cycle) PSIG 450 Relief Valve Set (Refrigerant Cycle) PSIG 450 Operating Chiller Water Volume Gal. 2.5 Operating Chiller Water Level Above Base Inches 9-13/16 Internal Chilled Water Pressure Loss Ft.

Locating and Mounting the Unit II. Connecting Chilled Water Lines III. Making Electrical Connections IV. Making Gas Connections V. Charging System with Water VI. Checking the Unit Operation VII. Adjusting Gas Input VIII. ’Balancing the System IX. Freezing Weather Protection Each of the above steps is discussed in detail in this instruction* Read the entire instruction before starting the installation. I. LOCATING AND MOUNTING THE UNIT The construction of Model 453, Series C, is such that the unit can be mounted on any suitable NON-COMBUSTIBLE BASE. However, there are several conditions, or circumstances, that result in the requirement of field - supplied supports. Some of these circumstances are: 1. When state and/or local building codes prohibit mounting the unit directly on a base. 2. When the unit is to be placed in an area where there is danger of standing water. - 3 - 36/453 Mounting Base The unit is supported on 3 rails attached to the bottom of the base. These rails extend the full length of the unit as shown in the dimensional drawing on page 2. The recommended types of mounting bases for all installations are: a. Precast concrete lintels. Use three lintels run the depth of the unit; one each under the right and left end and one at the center of the unit. b. Concrete blocks. Use a block under each comer plus a block under each of the two long sides midway between the comer blocks . Arrange the blocks so that the center rail as well as the front and back rail is supported. c. Concrete slab. Minimum thickness 4 inches. CAUTION: ALWAYS USE NON-COMBUSTIBLE MATERIAL FOR THE BASE.
