All Units Shall Be Installed by Licensed Contractors or Technicians. Read Manuals before Installation. • The location and structure should also be convenient for both installation and service. • The location should NOT be where discharge air and noise could annoy a neighbor. • The location should NOT be where drain may cause any damage to property or annoy a neighbor. • The location should NOT be where brazing work may cause fire or smoke to the surrounding materials.
INSTALLATION CLEARANCE REQUIREMENTS-INDOOR UNIT MAKE SURE OF ENOUGH SPACE FOR INSTALLATION AND MAINTENANCE To take into consideration the operational convenience and safety in installation, it is recommended to ensure enough space between the unit and the walls. Attention: If there are some additional function devices to install on the unit, be sure add to the installation space for the function devices.
Align the mounting plate holes with the holes drilled on the wall and put anchors or screws into the holes to secure the mounting plate. INSTALLATION OF INDOOR UNIT DRILL 3 INCH HOLE FOR PIPING/WIRING/DRAIN • • Locate the center where the hole will need to be drilled. Drill the holes of 2.5 – 3 Inches in diameter. A down pitch of about 1/4 inch per foot, as illustrated, is needed for the hole, to drain the condensate properly.
REFIT DRAIN HOSE FROM THE RIGHT TO THE LEFT SIDE If the drain hose needs to be refitted from its original position (right side) to left side of the indoor unit, careful handing is necessary as not to damage the unit. Refitting method: remove the drain hose from its original position, without breaking the hose. Remove the plug at the left side. Apply water-resistant glue to fit the drain hose and the fitting before securing it.
SHAPE THE DRAIN HOSE • • • To drain the condensate easily, the drain hose should be angled downward (pitched towards the drain direction at 1/4" per foot). Figures below from the 2nd to 5th show some incorrect practices. The drain hose may be extended using the hose supplied with the installation list. STUFF AND SEAL THE HOLE FOR COPPER LINE SET/WIRE and CABLE/DRAIN HOSE • Use putty to seal the wall hole. • Use a clamp (pipe fastener) to secure the pipe at the specified location.
INSTALLATION: OUTDOOR UNIT It is strongly suggested to install the outdoor unit above the ground, either on a platform or brackets as shown below. Heat pump unit must be lifted up from ground level, allowing any condensate to drain out of the drain pan in condensing unit. Otherwise, condensate may ice up causing damage to the unit. We suggest using YMGI brackets and condensate drainage fitting accessories.

OUTDOOR WIRING: OUTDOOR-INDOOR UNIT & DISCONNECT SWITCH BOX/CIRCUIT BREAKER/FUSE Remove the wiring diagram cover where also the handle for moving unit is located. Following the wiring diagrams on the unit or the wiring diagram manual that comes with the indoor unit to get familiar with the wiring and make sure everything is correct. If there is any discrepancy, always use the diagram that is attached to the units.
Running Interconnecting Refrigerant Lines: Use clean refrigeration grade copper pipe only. Keep the copper lines from kinking and transmitting any noise to walls, cabinets, etc. Pipe length not to exceed 150 feet, elevation not to exceed 35 feet. Insulate both the liquid and gas copper lines with at least 3/8-inch-thick insulation tubes. Band, tape and secure the refrigerant lines. Support copper lines at a proper distance apart to keep the tubes from sagging.
Connect Copper Pipes-Sweat Connection In this case, wrap a wet rag around the pipe to protect the valves or other components from being overheated. When using flux, rub the tube surface using steel wool to any oxidation then clean and dry to protect the system from any possible contamination.
PIPING GUIDE Set the packed pipes in a vertical position and then unwind them slowly. Do not unwind only one end of the coiled pipes. Use pulley or a bending tool to ensure a safe bending radius. Do not make any sharp or small radius bends. May also use rolling wheel to reduce internal pipe tension and avoid possible deformation. Use an elbow tool for consistent bending radius. Do not bend long sections of pipe without using bending tools. Maintain the minimum bending radius. Do not bend shot pipes.
INSTALLATION OF ACCESSORIES CONNECT REFRIGERANT PIPES Seal Copper Line Set/Wire Cable/Drain Hose Line Combination: Use factory-recommended components, as briefly illustrated below. Cover line set in a sequence, either from indoor to outdoor, or the other way. Secure line set covers onto the wall using factory-recommended accessories. LINE SET COVERS Do not damage line sets. OUTDOOR UNIT FOOT RISER OR BRACKETS BRKT-XXXX-SC1 Made of steel. Coated with weatherproof polyester powder.
VACUUM TESTING AND CHARGING VACUUM AND LEAKAGE CHECK VACUUM REFRIGERANT PIPES Evacuate the pipes between indoor and outdoor units, using vacuum pump and manifold/gauge set, to a minimum of 500 microns (service valves remain front seated). Hold for 30 minutes to check if the vacuum level is maintained. Using dry nitrogen or other leakage detection tool for leak checking. Be certain there is no pressure in the system when repairing a leak.
SYSTEM INSPECTION AND TRIAL RUNNING CHECK SYSTEM THOROUGHLY ADJUST REFRIGERANTGUIDELINE Check system thoroughly to make sure the unit is ready for trial running: check wires and pipes and air intake and discharge and power and thermostat and others necessary components. Right amount of refrigerant is very important. It is one of the basics to ensure a safe operation over time. Normally single zone outdoor unit is pre-charged with refrigerant for 25ft inter-connecting copper (liquid) line.
