Cautions on installation service 5
New refrigerant r410a 5
Pipe materials 5
Safety caution concerned to new refrigerant 5
1 required tools for r410a mixing of different types of oil may cause a trouble such as generation of sludge clogging of capillary etc accordingly the tools to be used are classified into the following three types 1 tools exclusive for r410a those which cannot be used for conventional refrigerant r22 2 tools exclusive for r410a but can be also used for conventional refrigerant r22 3 tools commonly used for r410a and for conventional refrigerant r22 the table below shows the tools exclusive for r410a and their interchangeability 6
Also prepare the following equipments for other installation method and run check 1 clamp meter 2 thermometer 3 insulation resistance tester 4 electroscope 6
General tools conventional tools can be used 6
In addition to the above exclusive tools the following equipments which serve also for r22 are necessary as the general tools 6
Note 1 when flaring is carried out for r410a using the conventional flare tools adjustment of projection margin is necessary for this adjustment a copper pipe gauge etc are necessary note 2 charging cylinder for r410a is being currently developed 6
Spanner or monkey wrench 9 hole core drill 10 hexagon wrench opposite side 4mm 11 tape measure 12 metal saw 6
Tools exclusive for r410a the following tools for r410a are required 6
Tools whose specifications are changed for r410a and their interchangeability 6
Vacuum pump use vacuum pump by attaching vacuum pump adapter 2 torque wrench 3 pipe cutter 4 reamer 5 pipe bender 6 level vial 7 screwdriver 6
Do not discharge flon gas into the air to protect the earth environment using the vacuum pump method clear the remained air nitrogen etc in the unit if the air remains the pressure in the refrigerating cycle becomes abnormally high and an injury and others are caused due to burst 7
Environment 7
Mm hexagonal wrench is required 7
Recharge of refrigerant 7
Use vacuum pump method for an air purge discharge of air in the connecting pipe in installation time 7
When recharge of the refrigerant is required charge the new refrigerant with the specified amount in the procedure as described below 7

Checks before operation 28
Cleaning of air filters 28
Daily maintenance 28
If you do not plan to use the unit for more than 1 month 28
Warning 28
Ask the dealer or an installation professional to re install the air conditioner to a new place or move it to another place and to observe the following items if the air conditioner is inappropriately installed by yourself it may cause electric shock or fire 29
Be sure to clean the heat exchanger with pressurized water if an commercially detergent strong alkaline or acid cleaning agent is used the surface treatment of the heat exchanger will be marred which may degrade the self cleaning performance for details contact the dealer 29
Caution 29
For environmental conservation it is strongly recommended that the indoor and outdoor units of the air conditioner in use be cleaned and maintained regularly to ensure efficient operation of the air conditioner when the air conditioner is operated for a long time periodic maintenance once a year is recommended furthermore regularly check the outdoor unit for rust and scratches and remove them or apply rustproof treatment if necessary as a general rule when an indoor unit is operated for 8 hours or more daily clean the indoor unit and outdoor unit at least once every 3 months ask a professional for this cleaning maintenance work such maintenance can extend the life of the product though it involves the owner s expense failure to clean the indoor and outdoor units regularly will result in poor performance freezing water leakage and even compressor failure 29
