DocumentDocumentCold Climate Heat Pump QUICK START GUIDE Thank you for choosing our product. Please read this Quick Start Guide carefully before operation and retain it for future reference. PLEASE READ FIRST Although very similar to traditional unitary heat pump systems, the ULTRANIXX Heat Pump Systems have a few key installation differences. 1. Each outdoor unit has two capacity and blower settings available on their corresponding control boards. (Detailed on the next page) · The 36kBtu models are rated for either 24kBtu or 36kBtu, nominal. · The 60kBtu models are rated for either 48kBtu or 60kBtu, nominal. · The efficiency ratings may change with a change in the capacity rating. · The outdoor and indoor capacities must match. 2. Both outdoor and indoor units feature service (shut-off) valves on both the liquid and gas (suction) valves. · The indoor unit does not contain a nitrogen charge, but a small amount (0.55lbs) of R-410A refrigerant. · Do not release this refrigerant to the atmosphere. · When evacuating (pulling a vacuum), pull from both the liquid and gas (suction) valves. This will ensure a proper evacuation has been performed and no air or other contaminants are in the refrigeration system. This will also mean proper evacuation takes less time. 3. The "W1" terminal activates the electric heat kit (if equipped). · The W1 terminal must be connected at the indoor and outdoor unit, and at the thermostat. · The heat kit is activated during defrost by the outdoor unit's "D" terminal. · For a heat pump application, not straight cooling or dual fuel, the "W1" control wire will connect to "W2" or "AUX" on the thermostat 4. This system contains PVE oil, not POE. Cross-contamination is prohibited. · Replace or flush existing line sets and/or coils in a retrofit application DO NOT DISCARD. STORE THIS INFORMATION IN A SAFE PLACE FOR FUTURE REFERENCE. OUTDOOR UNIT DIP SWITCH SETTINGS NOTE · ULTRANIXX outdoor units are configurable by a set of dip switches located in the upper right hand corner of the Main Control Board. · By default, the capacity is set at the larger capacity. Defrost, Power Mode, and Energy Savings are all set for the Standard, by default. · Power must be shut off prior to changing the dip switch settings. · The outdoor unit capacity must match the indoor unit capacity. The Power Mode and Energy Saving modes cannot be set simultaneously. SA2 ON ON ON 1 2 Capacity KU36UHO 36kBtu Configuration (Default) 24kBtu Configuration DIP OFF OFF 3 4 NOTE The ON position of the switch is towards the word "ON" located on the dip switch bank for the ULTRANIXX outdoor unit. DIP#1 ON OFF Capacity KU60UHO 60kBtu Configuration (Default) 48kBtu Configuration DIP#1 ON OFF Defrost KU36UHO KU60UHO Standard (Default) Strong Defrost DIP#2 ON OFF Operating Modes DIP#3 KU36UHO KU60UHO Standard (Default) OFF Energy Saving OFF DIP#4 OFF ON ON Strong Mode OFF OUTDOOR UNIT DIP SWITCH SETTING DESCRIPTION (Continued) DEFROST · Standard Defrost Mode is the default setting from the factory. · Strong Defrost Mode is used in cold but high humidity environments such as areas near large bodies of water. Select Strong Defrost Mode if it is common practice to extend defrost timing or increase the frequency of defrost cycles in the area where the system is installed. · In other cases where Standard Defrost Mode has been deemed insufficient, ensure the system is in good working order, the outdoor coil is clean, and the system is charged properly before changing the defrost setting to Strong Defrost Mode. STRONG MODE · In Strong Defrost Mode, the compressor will increase its speed at a higher rate than in Standard Defrost Mode, to reduce the ramp up time. · Strong Defrost Mode may be enabled if Standard Defrost Mode is deemed insufficient by the customer but note it is less efficient. · Always ensure the system is in good working order before enabling Strong Defrost Mode. ENERGY SAVING MODE · In Energy Saving Mode, the compressor will increase its speed at a lower slower rate. This can increase efficiency of the unit and provide additional dehumidification than the Standard or Strong modes. · Example: Energy Saving Mode may be used when the new system is replacing a system that was a half-ton smaller than the ULTRANIXX being installed. (The ULTRANIXX is not available in 1.5, 2.5 or 3.5 ton capacities, therefore ULTRANIXX would be set for the next highest capacity such as 2, 3 or 4 ton.) · The indoor CFM rating should also be reduced to match a normal CFM rating for the half-ton system design. This would mean that the set point would most likely be satisfied before reaching the system's full rated nominal capacity, reducing energy usage and improving dehumidification in cooling mode. NOTE Strong Mode and Energy Saving Mode cannot be enabled at the same time. Only one mode can be enabled. REFRIGERANT CHARGING · It is recommended to install a new 3/8" X 3/4" line set. · Filter driers are not recommended. Follow industry best practices for refrigerant piping.

Length COLD WEATHER STARTUP The UTRANIXX outdoor unit is factory equipped with a crankcase heater. · In outdoor temperatures below 32°F (0°C), ensure that power is applied to the outdoor unit for a minimum of 8 hours prior to startup. · Upon power application, check the operation of the crankcase heater by removing the front access panel, opening the compressor blanket, and checking to see if the crankcase heater is hot. · The crankcase heater ensures that liquid refrigerant is not present in the compressor before startup. · Liquid refrigerant is not compressible and will force the compressor oil out of the compressor. This will damage the compressor. INSTALLATION TIP To make the best use of the 8 hour preheat, do the following: 1. Set the outdoor and indoor units 2. Install the refrigerant piping 3. Perform a leak check 4. Pull a 500 micron vacuum 5. Connect line voltage to the outdoor unit 6. Weigh in additional charge, if needed 7. Open the indoor and outdoor shutoff valves 8. Power on the outdoor unit 9. Complete all other installation items once power is applied to the outdoor unit ELECTRIC HEAT KIT PRECAUTIONS ANY FIELD WIRING, IF PRESENT, ON L1/L2 MUST BE DISCONNECTED PERMANENTLY PRIOR TO HEAT KIT INSTALLATION! ALL POWER FOR THE AIR HANDLER WILL BE PROVIDED THROUGH THE HEAT KIT BREAKER! FAILURE TO DISCONNECT ALL FIELD WIRING ON THE L1/L2 TERMINAL CAN RESULT IN FIRE! AIR HANDLER DIP SWITCH SETTINGS NOTE · The ULTRANIXX Air Handlers are configurable by a set of dip switches located on the main control board. For proper operation, ensure that the air handler blower settings match the outdoor unit capacity and ducting design. Power must be off prior to changing the dip switch settings. · There are 8 static pressure settings for the blower. · Air handler's control box Dip Switches are located on the Main Control Board inside the air handler control box. · By default, the blower is set at Speed 4. · Dip switch settings are on the following two pages. · As with all air handling equipment, a duct system with a design that exceeds the capabilities of the installed equipment will result in customer discomfort, limited performance, and reduced equipment life. AIR HANDLER DIP SWITCH SETTINGS (Continued) NOTE · Only the "HEAT (SA2)" dip switches are adjusted. · The "COOL (SA1)" dip switches must remain in the "ON" position.

Please see the illustration below. NOTE Adding a proper Field-installed Transition will ensure proper airflow across the entire coil and allow space for inspecting the coil and heat exchanger. A minimum of 2inch is required between the heat exchanger and the A coil. 24V CONTROL WIRING SCHEMATIC Thermostat wiring without heat kit Blower shutdown during defrost NOTE Blower shuts down during defrost to prevent cold air in the space. Thermostat wiring with heat kit Blower shutdown during defrost NOTE Blower shuts down and heat kit does not activate. 24V CONTROL WIRING SCHEMATIC (Continued) Thermostat wiring with heat kit Activate heat kit during defrost NOTE Heat kit and blower runs during defrost. Thermostat wiring for Dual Fuel NOTE Dual Fuel Capable Thermostat is required so that the Furnace and the Heat Pump cannot run at the same time other than when the Heat Pump is in defrost.Adobe InDesign 19.3 (Macintosh) Adobe PDF Library 17.0
