The SpacePak system has been designed to reduce installation time and cost for
installing contractors. Small diameter, flexible tubing weaves around construction
obstacles and eliminates the need for large, cumbersome ductwork and major
structural renovations. Fittings simply snap securely into place with no tools required.
The typical installation diagram and guidelines listed below provide a quick reference
to ensure successful installation and operation of the system. More detailed and comprehensive information is available in our
Factory Trained Installer Handbook and on our website at www.spacepak.com.
 Outlets – The most important rule of thumb when installing
a SpacePak system is having the proper number of outlets.
Six (6) to Seven (7) outlets per ton are recommended for
optimal 35-40 CFM airflow from each outlet under normal
conditions to maximize aspiration.
 Outlet Placement – Outlets should be placed in the room where
they will create the least disturbance (floors, ceilings, walls)
and not infringe upon inhabitants with turbulent air. Traffic
patterns, drapes and bed placement are all factors to consider.
 Supply Duct–Ideally, all runs should be as equal in length as
possible. Keep the 2" duct length between 9 ft. and 30 ft. for
best performance. The longer the run, the lower the CFM
capacity. See performance chart in IOM.
 Main Trunk/Plenum – Maximize use of the main trunkline in
order to minimize the lengths of 2" duct. It will allow for an
easier installation and better performing, balanced system
if 2" duct lines are minimized.
 60/40 Rule – Always try to use a full flow “T” in larger, 4-5
ton systems. Never exceed a 60/40 split of outlets off the
main trunkline in order to maintain evenly distributed
airflow. A perfect 50/50 split is best.
 Locating Take-Offs – Distribute takeoffs as evenly as possible
along the main trunkline – no closer than 6" away from one
another. This will assure better balanced airflow.
 Sound Attenuators – The last 3 ft. of every run should use
a fully-fabricated SpacePak sound attenuator to reduce
outlet air sound.
 Return Air Duct – Minimize potential fan noise and maximize
performance of this acoustically lined duct by incorporating a
90-degree bend between the air handler and return grille.
