grounding

WarnIng:the unit cabinet must have an uninterrupted or unbroken electrical ground to minimize personal injury if an electrical fault should occur. Do not use gas piping as an electrical ground!

This unit must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code (ANSI/NFPA 70) or the CSA C22.1 Electrical Code. Use the grounding lug provided in the control box for grounding the unit.

Example:

AB = 451VBC = 460VAC = 453V

2. Determine the average voltage in the power supply.

3. Determine the maximum deviation:

4. Determine percent of voltage imbalance by using the results from steps 2 & 3 in the following equation.

max voltage deviationfrom average voltage

= 100 xaverage voltage

% Voltage Imbalance

= 1.32%6

454100 x

Example:

1. Measure the line voltages of your 3-phase power supply where it enters the building and at a location that will only be dedicated to the unit installation (at the units circuit protection or disconnect).

Unbalanced3-PhaseSupplyVoltageVoltage unbalance occurs when the voltages of all phases of a 3-phase power supply are no longer equal. This unbalance reduces motor efficiency and performance. Some underlying causes of voltage unbalance may include: Lack of symmetry in transmission lines, large single-phase loads, and unbalanced or overloaded transformers. A motor should never be operated when a phase imbalance in supply is greater than 2%. Perform the following steps to determine the percentage of voltage imbalance:

In this example, the measured line voltages were 451, 460, and 453. The average would be 454 volts (451 + 460 + 453 = 1,364 / 3 = 454).

The amount of phase imbalance (1.32%) is satisfactory since the amount is lower than the maximum allowable 2%. Please contact your local electric utility company if your voltage imbalance is more than 2%.

Example:From the values given in step 1, the BC voltage (460V) is the greatest difference in value from the average:

460 - 454 = 6454 - 451 = 3454 - 453 = 1

• Indryclimates,a90minutesettingisrecommended.• Inmoistclimates,a30minutesettingisrecommended.

To set the cycle timer, place the timing pin on the defrost control board to the desired time interval post.

notE: All units are shipped from the factory with the default time setting of 30 minutes. Longer settings are recommended for drier climate areas and shorter time intervals are recommended for moist climate areas. Maximum heating performance can be acheived by setting the time to 90 minutes.

Defrost control boardOperational Information• Terminalsr - rc must have 24±V present between

them in order for the time delay and defrost sequences to be operational.

• Ajumperbetweenthet2 - DFt test pins will communicate to the board that the defrost T-stat is closed (if the compressor is running). The defrost thermostat tells the board whether a defrost cycle needs to be started or terminated. notE: The defrost T-stat is closed at 32° F or below and is open at 68° F or above, but it’s state is unknown if the temperature is between 32° F and 68° F.

• With the DFT closed, the unit will run for 30/60/90minutes in heat mode and then defrost the outdoor coil. The defrost will turn off the outdoor fan, turn on the compressor and raise the coil temperature to 68° F. This will open the DFT and terminate the defrost. If the DFT does not open the defrost will end after 10 minutes.

• Toover-ridethedefrostboardandinitiateafasterdefrosttest in 5, 10 or 15 seconds as determined by the 30, 60 or 90 minute defrost pin settings (factory setting is 30 minutes), jumper the tEst terminal to the c (common) terminal while the compressor is in heat mode.– This will bypass the compressor off delay when the

unit goes into defrost test and if left in defrost test, the delay will be bypassed when the test is terminated by the processor. notE: If the jumper is removed before the test is over, the processor will perform the remainder of a normal defrost. See bullett 2 above.

• To switch from no-delay to delay, remove the pin from the no - delay pin location and shift it to the delay pin location. The delay/no-delay pin concerns compressor operation during defrosts. The default setting is delay.– Reciprocating compressors should only use this

setting in conjunction with an approved hard start kit.

– Scroll compressors that have noise issues while going into or coming out of defrost should use this 30 second delay to reduce the defrost noise.

– Manually initiating a defrost will cause the compressor to run continually when entering defrost.

Normal defrost operationTo test normal defrost operation when the temperature is above 35° F, jumper r to DFt on the board and allow the unit to run for 30 minutes. Defrost will continue until the r to DFt jumper is removed or for 10 minutes. Remove the jumper.

The 5 minute time delay feature can be shortened 1 time to 1 second by jumping the test to c terminal. Remove the jumper and repeat as desired.

notE: If jumper is left on the test to common pins permanently, the defrost cycle will become inoperable.

Defrost Test Procedure1. Jumper t2 to DFt at the test terminals.2.Withunitrunninginheatmode,shortthetEst terminal

to the common terminal near it. This will speed up the board and cause it to enter defrost mode in 5/10/15 seconds depending on the defrost time selection. Compressor delay will not function during speed-up.

3. This test will end in 5 seconds if the tEst-common short is not removed.

4. Remove both the short and the t2 to DFt jumper to terminate the defrost cycle. The 30 second compressor delay should operate normally.

5. Test is complete, reset thermostat to home owner preference.

anti short cycle timer testThe 5 minute time delay feature can be bypassed or shortened to 1 second by jumping the test to c terminal.

notE: If jumper is left on the test to common pins permanently, the defrost cycle will become inoperable.

• Chargingtablesarevalidforavarietyof indoor,returnairconditionsandaremostinfluencedbytheoutdoorambient temperature, outdoor fan operation and the unit operating voltage. Before using these charts, make sure the unit is in a stable operating mode. As shown in Tables 2 - 17 (pages 10 - 15), the ideal system sub-cooling can vary over the range of operation. Reference the tables to determine the ideal amount of sub-cooling for a given liquid pressure. Units charged to other values will not perform at the rated unit efficiency (EER) or rated Coefficient of Performance (COP) in heating mode.

• read all notes and warnings for the cooling-mode charging tables prior to using these heating-mode charge verification tables. always use safe and environmentally sound methods when handling refrigerant handling or servicing the unit. review the factory literature and safety warnings prior to servicing.

• Whenrepairingsystemleaks,alwaysuseanitrogen(inert)gastoprotecttherefrigerantsystemandpressurecheck the repair before re-charging. Always replace the filter-dryers when performing any repair to the refrigeration system with one capable of acid removal. After completing the repairs, evacuate the system to 350 - 500 microns and weigh in the refrigerant to the amount specified on the unit rating label.

• Before using Tables 18 - 25 (pages 17-19), determine the outdoor ambient temperature and the return air temperature to the unit. Locate the appropriate location on the units verification table based on those measurements to determine the ideal liquid line pressure and temperature. Verify the outdoor fan and compressor are running and the outdoor coil is free from frost accumulation. Also verify the system is not operating in defrost mode before inspecting the system.

• Always use quality instruments that are in good working order to measure the actual operating point of the refrigeration system. The liquid line temperature should be within 2 degrees of the ideal value and the pressure should be within 2%.

• The most reliable way of verifying the system is at the correct charge is to evacuate the system and weigh in the charge to the amount shown on the rating label. However, if an inspection with these verification tables does not line up with the values shown and the ambient temperature is above 50˚ F, then a more accurate way to inspect the system for proper charge is with the cooling mode charging tables. Switch the unit into cooling mode and allowittooperateandstabilizeforafewminutestheninspecttheunitoperationwiththecoolingmodetablesandprocedures.

before changing the unit charge, always inspect the following items first:1. Inspect the liquid line temperature on the inlet and outlet of the filter dryers. If it is the factory dryer and in good

condition there should be no temperature difference. If the temperature difference is larger than 5˚, replace the filter dryer with one that is bi-directional and has acid removal capability. Refer to the unit RPL for the recommended partnumberandsize.

2. Inspect the units input voltage. Units operating at less than 95% of the nominal voltage may deviate more from the chart then previously stated.

3. Inspect the input voltage for a phase imbalance. Units with greater then a 2% disparity will not operate at the rated performance.

4. Verify that the unit filters are installed and are clean. The pressure drop across the filters should not exceed 0.08 in-W.C.

5. Inspect the indoor coil, indoor blower and blower motor for cleanliness, clogging, and proper operation.6. Inspect the system for leaks. If any leaks are detected, repair them immediately. Re-inspect the return air and

ambient temperatures and verify that the correct system point on the verification chart was selected.

Do not use the tables in systems that have the fan cycling under a low-ambient control. Low-ambient controls are for cooling operation. In heating mode, the low ambient control should be disabled. Unless the unit is in defrost mode, the outdoor fan should always operate in conjunction with the compressor.

notEs:

1. All pressures are listed psig and all temperatures in °F2. Discharge temperatures greater than charted values
