INSTRUCTIONS:

1.Determine Ihe area lo be cooled In square feet and locale that point on the left srde of chart

2. Move horizontally		across to		the center lrne of Band A, 0 or	C	Room Air	Conditioner
according to the condition of the cethng in the area to be cooled.					--	MAP	FACTORS
Band	A-Occupied	Space	Above	Ceding	--	MAP	FACTORS
Bmnd	B-Insulated	Ceiling	Under	Athc
Band C-Non-Insulated		Ceiling		Under Attrc

3.From center of band move within the band to left for more northerly exposure or right for more westerly exposure.

4.From thus point, read down to bonom of chart to determine required Btu/hr output. Write the Btulhr figure in the space indicated below.

5.- Btulhr (from number 4 above).

6.--- Locate your geographrc area on Inset map and multlply factor shown by figure rn number 5

?.~-_ If room air conditioner IS intended prlmarlly for nrghl- time coohng, subtract 30% (from figure In number 6)

6.p Subtract 30 Btuihr from ftgure in number 7 (or 6) for each linear foot of wall seoaratino the area lo be cooled

from another cooled room. -

9.- If more than two people occupy area. add 600 Btuihr per person (to figure rn number 8); if only one person, subtracl 600 Btu/hr.

lo.- Add 4000 Btu/hr (to figure in number 9) if area to be cooled tncludes krtchen.

For best results, a room condittonmg unit or umts with a cooling

capacity rahng close to that estimatedabove should be selected: A smaller capacity unit operatmg conhnuously wi!l contribute more to comfort than a larger capacity unit operating inlermit-

tently.
