2 IMPOR T ANT! Please Read Bef ore Star ting This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an impor- tant par t of your job to install or service the system so it oper- ates saf ely and efficiently .
3 2. The standards for minimum room v olume are as f ol- lows . (1) No partition (shaded por tion) (2) When there is an eff ective opening with the adjacent room f or ventilation of leaking refrigerant gas (opening without a door , or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).
New tool? 4 1-2. Pre vent impurities including water , dust and oxide from entering the tubing. Impurities can cause R410A refrigerant deterioration and compressor defects . Due to the f eatures of the refrigerant and refrigerating machine oil, the pre vention of w ater and other impurities becomes more impor tant than ev er .
5 Valve Liquid 3-2. Use R410A e xclusive cylinder only . Single-outlet valve (with siphon tube) Liquid refrigerant should be recharged with the cylinder standing on end as shown. New refrigerant R410A cannot be used f or earlier models 1. Compressor specifications are different.

W ARNING Al ways c heck the gas density limit for the r oom in which the unit is installed. 1-10. Check of Limit Density When installing an air conditioner in a room, it is neces- sar y to ensure that e ven if the refrigerant gas accidentally leaks out, its density does not e xceed the limit le vel f or that room.

15 1-13. Example of T ubing Size Selection and Refrigerant Charge Amount Additional refrigerant charging Based on the values in T ables 1-2, 1-3, 1-4 and 1-7, use the liquid tubing size and length, and calculate the amount of additional refrigerant charge using the formula below .
Checking of limit density Density limit is determined on the basis of the size of a room using an indoor unit of minimum capacity . For instance, when an indoor unit is used in a room (floor area 80 ft 2 × ceiling height 8.8 ft. = room volume 704 ft.

61 6. HO W T O PROCESS TUBING 6-1. Connecting the Refrigerant T ubing Use of the Flaring Method Many of con v entional split system air conditioners emplo y the flaring method to connect refr igerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts.
62 Caution Before Connecting T ubes Tightly (1) Apply a sealing cap or water-proof tape to pre v ent dust or water from entering the tubes bef ore they are used. (2) Be sure to apply refrigerant lubricant to the matching surf aces of the flare and union bef ore connecting them together .
63 Fig. 6-8 Fig. 6-9 6-3. Insulating the Refrigerant T ubing T ubing Insulation Thermal insulation must be applied to all unit tubing, including distribution joint (purchased separately). * F or gas tubing, the insulation material must be heat resistant to 248°F or abov e.
64 Fig. 6-10 Fig. 6-11 6-4. T aping the T ubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes per mit) should be taped together with armor ing tape in 1 bundle . T o prev ent the condensation from ov erflowing the dr ain pan, keep the dr ain hose separate from the refrigerant tubing.
