Application Manual and System Selection Guide

SpacePak provides the Kwik-Way Heating & Air 
Conditioning sizing sheet (see Figure 1.1) to help dealers 
calculate the heat gain and/or heat loss of a structure to 
assure maximum comfort for the occupants. The form is 
easy to use; provides an accurate analysis; and is essential 
for sizing the structure and selecting the appropriate 
SpacePak equipment.
The Kwik-Way form also provides a room-by-room 
analysis for selecting the appropriate number of air 
outlets  and  balancing  orices  for  each  room.  Proper 
system balancing is the key to proper system operation.
Before equipment can be selected for an installation, 
it is imperative that the heat gain (for cooling) and/
or the heat loss (for heating) be calculated for the 
home or business in which the Space Pak system 
will be installed to assure maximum comfort for the 
occupants.
Prior to performing your calculations, complete a oor 
plan of the structure, such as the one shown in Figure 
1.2, which contains the following measurements (all of 
which can be rounded off to the nearest foot):
1. Square footage (length x width) of each room. 
The small amount of time that is spent in designing the 
SpacePak  system  will  result  in  a  satised  customer 
every time. We have provided a number of extremely 
important guidelines in this application manual involving 
the air distribution system design, such as static 
pressures, plenum duct and supply tubing runs, and 
location of room outlets.
We recommend reviewing these guidelines carefully, as 
they are intended to save time on the job, help obtain 
the best possible installation, and provide continuous, 
trouble-free operation.

2. Linear feet of exposed (outside) wall in each room. 
If more than one exposed wall in each room, add the 
lengths together. If the wall has two different kinds of 
construction (part brick, part frame), measure each 
section as though it were a separate wall. If the wall 
is partially above grade and more than 3-feet below 
grade, measure each section as though it were a 
separate wall. If there is an open stairway alongside 
an exposed wall, the entire wall area (all the way to 
the ceiling of the sec-ond oor) is to be added to the 
rst oor.
3. Ceiling height in each room.
