described in t his manual.

For any service which requires ent ry int o t he refrigerant sealed syst em, Federal regulat ions require t hat t he work is performed by a t echnician having a

· This heat pump must be properly inst alled in accordance

Class II or Universal cert ificat ion.

wit h t hese inst ruct ions before it is used.
· All wiring should be rat ed for t he amperage value list ed on t he rat ing plat e. Use only copper wiring.
· All elect rical work must be complet ed by a qualified elect rician and complet ed in accordance wit h local and nat ional building codes.
· Any servicing must be performed by a qualified individual.

· All air condit ioners cont ain refrigerant s, which under federal law must be removed prior t o product disposal. If you are get t ing rid of an old product wit h refrigerant s, check wit h t he company handling disposal.
· These R- 410A heat pumps syst ems require t hat cont ract ors and t echnicians use t ools, equipment and safet y st andards approved for use wit h t his refrigerant .

DO NOT use equipment cert ified for R22 refrigerant only.

WARNING RISK OF ELECTRIC SHOCK. Could cause injury or deat h.

· An adequat e ground is essent ial before connect ing t he power supply.
· Disconnect all connect ed elect ric power supplies before servicing.

· Repair or replace immediat ely all elect rical wiring t hat has become frayed or ot herwise damaged. Do not use wiring t hat shows cracks or abrasion damage along it s lengt h or at eit her end.

WARNING RISK OF FIRE. Could cause injury or deat h.
· Do not st ore or use combust ible mat erials, gasoline or ot her flammable vapors or liquids in t he vicinit y of t his or any ot her appliance.

WARNING
This appliance is not int ended for use by persons (including children) wit h reduced physical, sensory or ment al capabilit ies, or lack of experience and knowledge, unless t hey have been given supervision or inst ruct ion concerning use of t he appliance by a person responsible for t heir safet y. Children should be supervised t o ensure t hat t hey do not play wit h t he appliance.
To avoid danger of suffocat ion, keep t he plast ic bag or t hin film used as t he packaging mat erial away from young children.
Be sure not t o allow foreign mat erials (oil, wat er, et c) ent ering t he refrigerant piping. Seal t he ends of refrigerant piping before st orage.
For inst allat ion purposes, be sure t o use t he part s supplied by t he manufact urer or ot her prescribed part s. The use of non- prescribed part s can cause serious accident s such as t he unit falling, wat er leakage, elect ric shock, or fire.

IMPORTANT SAFETY INFORMATION

CAUTION
It is highly recommended t hat you do not open or close t he st op valves when t he out door t emperat ure is below – 5°F (- 21°C) as t his may cause refrigerant leakage.
Make sure power is t urned on for at least 12 hours aft er periods of being powered down in an 32 °F (0° C) environment or lower.
Do not t ouch t he fins of t he coil. Touching t he coil fins could result in damage t o t he fins or personal injury such as skin rupt ure.
Ensure t he power circuit capacit y is adequat e for all loads connect ed t o t he elect rical service panel. Increase t he conduct or and panel capacit y if t he t ot al elect rical loads exceed t he power source capacit y.
Cont act t he power ut ilit y if t he power provided is below equipment rat ing plat e requirement s.
Be sure t o inst all a breaker of t he specified capacit y.
Regulat ion of cables and breaker differs from each localit y, refer in accordance wit h local rules.
Do not use exist ing refrigerant lines.

Use refrigerant t ubing t hat is clean and free of any cont aminat ion which may cause damage t o t he syst em including sulfur, copper oxide, dust , met al chips, powder, oil or wat er.
Avoid brazing lines t oget her. Use a cont inuous lengt h of copper t ubing as oxides formed during improper brazing t echniques can damage t he equipment .
Do not use copper pipes t hat have a collapsed, deformed, or discolored port ion (especially on t he int erior surface). Ot herwise, t he expansion valve or capillary t ube may become blocked wit h cont aminant s.
Improper line sizing will degrade performance. Peak pressure of R410A is much higher t han R22. Use copper t ubing wit h adequat e wall t hickness.
To prevent breaking of t he pipe, avoid sharp bends. Bend t he pipe wit h a radius of curvat ure of 4 in. (100 mm ) or more.
If t he pipe is bent repeat edly at t he same place, it will break.

· The refrigerant lines should be as short as possible t o ensure efficiency.
· Lubricat e t he flare fit t ings wit h refrigerant oil prior t o assembly.
· Always use a t ubing bender when creat ing bends in t he refrigerant t ubing.
· Align t he t ubing wit h t he flare fit t ings before at t empt ing t o t hread t he flare nut . Cross- t hreading can damage t he fit t ing. Always st art t hreads by hand.
· Please refer t o fast ening t orque in t he “Pipe Specs and Fast ening Torque” sect ion.
· Seal any t ubing t hat is not being used t o avoid mat erial damage.
