important SAFETY INFORMATION INSTALLER: Please read all instructions before servicing this equipment. Pay attention to all safety warnings and any other special notes highlighted in the manual. Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING indicates a potentially hazardous situation that if not avoided, could result in personal injury or death.
PAGE 3
HEAT PUMP INSTallATION General Information Split system heat pumps are designed only for outdoor rooftop or ground level installations. This unit has been tested for capacity and efficiency in accordance with AHRI Standards and will provide many years of safe and dependable comfort, providing it is properly installed and maintained. Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards.
PAGE 4
Connecting Refrigerant Tubing Between the Indoor & Outdoor Unit connection of the liquid valve and not inside the outdoor unit’s distributor. Perform steps 1 - 5 if the outdoor restrictor needs to be changed. CAUTION: When servicing, cover or seal openings to minimize the exposure of the refrigerant system to air to prevent accumulation of moisture and other contaminants.
PAGE 5
2. Insert a light-gauge wire hook between the valve body and the restrictor orifice (Figure 3, page 5) while being careful not to scratch either part. Carefully remove the restrictor orifice from the valve body. 3. Check the actual size of the new orifice. NOTE: The size is stamped on its side. Do not use pin gauges to measure the orifice diameter. 4. Insert the new orifice into the valve body, with the rounded end facing into the valve. See Figure 2.

PAGE 7
Blower Time Delay Relay (Select Models) A time delay relay may be provided with the unit and must be installed in the indoor section. The relay will keep the indoor blower running an additional 40 seconds for increased cooling efficiency after the outdoor unit shuts off. The relay has four terminals and one mounting hole. • Connect terminal 1 to load side of blower relay. • Connect terminal 2 to terminal R of T’stat. • Connect terminal 3 to common terminal at blower relay or transformer.
PAGE 8
START UP & ADJUSTMENTS Pre-Start Check List √ Verify the unit is level and has sufficient clearances for unobstructed airflow. √ Verify the outdoor coil and top of the unit are free from obstructions and debris, and all equipment access/ control panels are in place. √ Verify that the line voltage power leads are securely connected and the unit is properly grounded. √ Verify that the low voltage wires are securely connected to the correct leads on the low voltage terminal strip.
PAGE 9
Defrost Control Board Operational Information • Terminals R - RC must have 24±V present between them in order for the time delay and defrost sequences to be operational. • Jumpering the T2-DFT test pins will communicate to the board that the defrost T-stat is closed (if compressor is running).The defrost thermostat tells the board whether a defrost cycle needs to be started or terminated.

Refrigerant Charging WARNING: T4BE Split System Heat Pumps are shipped charged with R410A refrigerant and ready for installation. If repairs make it necessary for evacuation and charging, it should only be attempted by qualified trained personnel thoroughly familiar with this equipment. Under no circumstances should the owner attempt to install and/or service this equipment. Failure to comply with this warning could result in property damage, personal injury, or death.

T4BE Refrigerant Charging Charts - Cooling Only Application notes for using cooling charging charts • This equipment’s cooling system contains refrigerant under high pressure. 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. • When repairing system leaks, always use a nitrogen (inert) gas to protect the refrigerant system and pressure check the repair before re-charging.
