The factory charge for 3/8" lineset 9 oz. When using other length or diameter liquid lines, charge adjustments are required per the chart above. Charging Formula: [(Lineset oz/ft x total length) — (factory charge for lineset)] = charge adjustment Example 1: System has 15 ft of line set using existing 1/4" liquid line. What charge adjustment is required? Formula: (.27 oz/ft x 15ft) — (9 oz) = (-4.95) oz. Net result is to remove 4.95 oz of refrigerant from the system Example 2: System has 45 ft of existing 5/16" liquid line. What is the charge adjustment? Formula: (.40 oz/ft. x 45ft) — (9 oz.) = 9 oz. Net result is to add 9 oz of refrigerant to the system LONG LINE APPLICATIONS An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units. For Air Conditioner systems, the chart below shows when an application is considered Long Line.

In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause degradation in performance. Use either the accessory Time —Delay Relay KAATD0101TDR or a furnace equipped with TDR. Most Bryant furnaces are equipped with TDR. NOTES: 1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included. 2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners. Ratings for other combinations are determined under DOE computer simulation procedures. 3.

A05178 Fig. 3 - Liquid Line Filter Drier Evacuate Refrigerant Thbing and Indoor Coil UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Never use the as a vacuum Refrigerant tubes and indoor coil should be evacuated using the recommended deep vacuum method of 500 microns. The alternate triple evacuation method may be used (see triple evacuation procedure in service manual). Always break a vacuum with dry nitrogen. Deep Vacuum Method The deep vacuum method requires a vacuum pump capable of pulling a vacuum of 500 microns and a vacuum gage capable of accurately measuring this vacuum depth. The deep vacuum method is the most positive way of assuring a system is free of air and liquid water. A tight dry system will hold a vacuum of 1000 microns after approximately 7 minutes.

Ensure tubes are not rubbing against each other or any sheet metal or wires. Pay close attention to feeder tubes, making sure wire ties on feeder tubes are secure and tight. Installing with Indoor Piston Outdoor Unit Connected to Factory Approved Indoor Unit Check piston size shipped with indoor unit to see if it matches required indoor piston size. If it does not match, replace indoor piston with correct piston size. NOTE: Correct pistons are shipped with select outdoor units in the accessory bag and are only for use in certain qualified and approved fan coils, i.e. F134C. (See Product Data for list of approved fan coils that use accessory piston.) The piston included with the FFMANP* and FPMAN* fan coils are unique to those products and CANNOT be replaced with the piston shipped with outdoor unit. Refer to the AHRI Directory to check if a certain combination can use a piston or requires an accessory TXV. When changing indoor piston, use a back — up wrench. Hand tighten hex nut, then tighten with wrench 1/2 turn. Do not exceed 30 ft — lbs. The indoor piston contains a Teflon ring (or seal) which is used to seat against the inside of distributor body, and must be installed properly to ensure proper seating.

Install Electrical Accessories Refer to the individual instructions packaged with kits or accessories when installing. Start -Up UNIT OPERATION AND SAFETY HAZARD Failure to follow this caution may result in personal injury, equipment damage or improper operation. • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure. • Compressor dome temperatures may be hot. PERSONAL INJURY HAZARD Failure to follow this caution may result in personal injury. Wear safety glasses, protective clothing, and gloves when handling refrigerant and observe the following: • Front seating service valves are equipped with Schrader valves. Follow these steps to properly start up system: 1. After system is evacuated, fully open liquid and vapor ser- vice valves. 2. Unit is shipped with valve stem(s) front seated (closed) and caps installed. Replace stem caps after system is opened to refrigerant flow. Replace caps finger -tight and tighten with wrench an additional 1/12 turn. 3. Close electrical disconnects to energize system. 4. Set room thermostat at desired temperature. Be sure set point is below indoor ambient temperature. 5. Set room thermostat to COOL and fan control to ON or AUTO mode, as desired. Operate unit for 15 minutes. Check system refrigerant charge. Sequence of Operation Turn on power to indoor and outdoor units. Transformer is energized. On a call for cooling, thermostat makes circuits R-Y and R-G. Circuit R-Y energizes contactor, starting outdoor fan motor and compressor circuit. R-G energizes indoor unit blower relay, starting indoor blower motor on high speed. When thermostat is satisfied, its contacts open, de -energizing contactor and blower relay. Compressor and motors stop. If indoor unit is equipped with a time -delay relay circuit, the indoor blower will run an additional 90 seconds to increase system efficiency. Check Charge Factory charge amount and desired subcooling are shown on unit rating plate. Charging method is shown on information plate inside unit. To properly check or adjust charge, conditions must be favorable for subcooling charging. Favorable conditions exist when the outdoor temperature is between 70°F and 100°F (21.11°C and 37.78°C), and the indoor temperature is between 70°F and 80°F (21.11°C and 26.67°C). Follow the procedure below: Unit is factory charged for 15ft (4.57 m) of lineset. Adjust charge by adding or removing 0.6 oz/ft of 3/8 liquid line above or below 15ft (4.57 m) respectively. For standard refrigerant line lengths (80 ft/24.38 m or less), allow system to operate in cooling mode at least 15 minutes. If conditions are favorable, check system charge by subcooling method. If any adjustment is necessary, adjust charge slowly and allow system to operate for 15 minutes to stabilize before declaring a properly charged system. If the indoor temperature is above 80°F (26.67°C), and the outdoor temperature is in the favorable range, adjust system charge by weight based on line length and allow the indoor temperature to drop to 80°F (26.67°C) before attempting to check system charge by subcooling method as described above. If the indoor temperature is below 70°F (21.11°C), or the outdoor temperature is not in the favorable range, adjust charge for line set length above or below 15ft (4.57 m) only. Charge level should then be appropriate for the system to achieve rated capacity. The charge level could then be checked at another time when the both indoor and outdoor temperatures are in a more favorable range. NOTE: If line length is beyond 80 ft (24.38 m) or greater than 35 ft (10.7 m) vertical separation, See Long Line Guideline for special charging requirements. Final Checks IMPORTANT: Before leaving job, be sure to do the following: 1. Ensure that all wiring is routed away from tubing and sheet metal edges to prevent rub -through or wire pinching. 2. Ensure that all wiring and tubing is secure in unit before adding panels and covers. Securely fasten all panels and covers. 3. Tighten service valve stem caps to 1/12-turn past finger tight. 4. Leave Owner's Manual with owner. Explain system opera- tion and periodic maintenance requirements outlined in manual. 5. Fill out Dealer Installation Checklist and place in customer file. CARE AND MAINTENANCE For continuing high performance and to minimize possible equipment failure, periodic maintenance must be performed on this equipment. Frequency of maintenance may vary depending upon geographic areas, such as coastal applications. See Owner's Manual for more information.
