HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS PRE INSTALLATION Determine the best location for mounting the indoor unit, it must be located a minimum of 4 ft (6 ft or more recomended) from the floor and no less than 6” from ceiling. CONTROLS AND COMPONENTS Units are supplied with a wireless remote control, which communicates with the unit microprocessor control. The return air temperature sensor mounted in the indoor unit provides input to the control for system operation.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS INDOOR UNIT INSTALLATION ! CAUTION ! Follow Instructions, failure to follow instructions may cause possible malfunction and void any warranty. Remove indoor and outdoor units from the carton/box. Indoor unit carton contains, remote control and batteries, ensure these are kept in a safe place during installation. Locate area to install indoor unit the unit should be located a minimum of 6 ft. from the floor and 6” from the ceiling.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS INDOOR UNIT INSTALLATION Prepare the evaporator for mounting by removing the mounting bracket from the rear of the indoor unit. Use a Phillips head screwdriver to remove the unit pipe strap. If the unit is a heat pump the defrost sensor also must be undone from its retainer. If mounting the unit on an inside wall, use the knockouts provided on the left and right sides of the unit to route the piping and wiring connections through.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS INDOOR UNIT INSTALLATION Prepare unit line set connections Rotate refrigerant line stubs gently to 90° (if mounting on an outside wall). For other line set configurations align the stubs as required. Feed the 14 AWG interconnect wiring between indoor and outdoor through the unit electrical connection (maximum number of 6 wires is required) (if required by local codes an electrical connector can be attached to the rear of the unit).
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS INDOOR UNIT INSTALLATION Install unit on mounting bracket Feed the line set stubs/condensate hose/ wiring connections through a ø 3” hole in the wall. Position the evaporator so that the “key” slots on the back of the unit slide onto the tabs on top of the mounting bracket. Then push the lower portion of the evaporator against the bracket until it latches into the mounting bracket. 18,000 Btuh shown through the wall penetration, also check that the wall is plumb.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS Refrigerant Line Set Piping Interconnecting line set between the outdoor unit and the indoor unit, must have both refrigerant lines insulated as the expansion device is located in the outdoor unit. Gently bend the line set stubs from the in- door unit to the desired location. Using 2 x 10”/12” Crescent wrenches remove the flare nuts from the indoor unit line stubs. The indoor unit is filled with a dry gas, check for release of this to ensure that no leaks are present.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS OUTDOOR UNIT INSTALLATION Evacuation Gauges can now be attached to the service ports - SERVICE PORTS HAVE A 5/16” CONNECTION TO GAUGES, which is different from the norm for R-22. You will need specific hoses or an adaptor for the 5/16” connection. tem to remove all traces of moisture. See “System Start-Up” section to fine-tune the refrigerant charge.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS OUTDOOR UNIT INSTALLATION Electrical Wiring Installation ! CAUTION outdoor unit must be a point to point i.e. the terminal that the wire is attached to on the outdoor unit must be the same terminal it is wired to in on the indoor unit. ! Electrical Wiring should be done by a certified electrician in accordance with all National ElectricalCode (NEC) and local state/city building codes.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS OUTDOOR UNIT INSTALLATION HEAT PUMP WIRING If the system is a heat pump the defrost sensor must be connected from the indoor unit to the defrost sensor in the outdoor unit. Standard lead length is 25 ft, if a longer length is required then cut the lead and extend using thermostat wire. Note: use of colored wire (supplied with line set) and defrost sensor connected (heat pump only).
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS OUTDOOR UNIT INSTALLATION 12) Condensate Hose: The unit is provided with approximately 18” of condensate hose connected. Hose connection is sized to accept a 3/4” OD or 5/8” ID clear plastic hose to then extend to building drain. There is approximately 6’ of additional drain hose supplied with the (accessory) line set. All condensate hose extensions should be in accordance with local building codes.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS Start the indoor unit, cooling mode is only allowed when the outside ambient temperature is above 60° F to prevent damage to the compressor. Unit has a 3 minute time delay before the compressor start up operation. Note: If interconnect is less then 25 feet a small amount of refrigerant may need to be reclaimed to achieve the proper charge for optimal operation. We recommends fine tuning using the “Superheat” method.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS FIELD CHARGING Instructions: 1. Measure suction pressure and determine evaporator-refrigerant temperature on R410A scale of low-side gauge. 2. Measure suction-line temperature on suction line of the unit. 3. Measure outdoor and indoor temperatures. 4. Determine from the table what the superheat should be for the indoor and outdoor temperatures. 5. Adjust charge if needed. Be sure unit is running at stabilized condition.

HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS Features of Heating Operations Important: Heating operation will cease at approximately 15° F outdoor temperature due to a sensor located in the outdoor unit. This product does not contain supplemental electric heat, therefore other means of heat need to used when this system ceases operation at low outdoor ambients. Basic principles and performances • The Heat Pumps absorb heat from the outdoor air and transfers it indoors to heat the indoor air.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS Maintenance To clean the surface of the air conditioner: • Use a soft and dry cloth to wipe the air conditioner off, or use a vacuum cleaner to clean it. • If the air conditioner is very dirty, use a damp soft cloth with a neutral household detergent to clean the surface of the unit. Note: If the air filter screen is blocked by dust or dirt, the performance of cooling and heating will be affected, and the operation noise and power consumption will increased.
HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS Basic Operation Characteristics Problem Cause The unit can not be restarted just after shut down. (RUN light is on) Restart is delayed for 3 minutes after shut down to protect the unit. Three-minute protection timer incorporated in the microcomputer actuates automatically. Except when power is connected, this function does not actuate. Air does not blow out at starting of heating operation.
