Maximum allowed elevation is 10,000 feet (3000 meters) above sealevel or lower.2. Locate unit away from windows, patios, decks, etc. where unitoperation sound may disturb customer.3. Ensure that vapor and liquid tube diameters are appropriate for unitcapacity.4. Run refrigerant tubes with no bends with centerline bend radius lessthan 2.5 times the external pipe diameter.5. Leave some slack between structure and unit to absorb vibration.6. When passing refrigerant tubes through the wall, seal opening withRTV or other pliable silicon-based caulk. (See Fig. 1.)7. Avoid direct tubing contact with water pipes, duct work, floorjoists, wall studs, floors, and walls.8. Do not suspend refrigerant tubing from joists and studs with a rigidwire or strap which comes in direct contact with tubing.(See Fig. 1.)9. Ensure that tubing insulation is pliable and completely surroundsvapor tube.10. When necessary, use hanger straps which are 1 in. (25 mm) wideand conform to shape of tubing insulation. (See Fig. 1.)11. Isolate hanger straps from insulation by using metal sleeves bent toconform to shape of insulation.12. Provision shall be made for expansion and contraction of long runsof piping.13. Piping and fittings shall be protected as far as possible againstadverse environmental effects. For example, the accumulation ofdirt and debris.14. Piping should be installed to reduce the likelihood of hydraulicshock damaging the system.15. Certified piping and components must be used in order to protectagainst corrosion.16. Flexible pipe elements shall be protected against mechanicaldamage, excessive stress by torsion, or other forces. They should bechecked for mechanical damage annually.25TPB7Performance™ Series 2-Stage Heat Pumpwith Puron® Refrigerant andInteliSense™ Technology2 To 5 TonsWARNING!ELECTRICAL SHOCK HAZARDFailure to follow this warning could result in personal injury or death.Before installing, modifying, or servicing system, main electricaldisconnect switch must be in the OFF position.
