• GFCI (Ground Fault Circuit Interrupter) (Fig 6)
A GFCI operates on the principle of monitoring the
imbalance of current between the circuit’s ungrounded
(hot) and grounded (neutral) conductor. It does not
monitor the grounding conductor, and so it will still
operate in a circuit without a ground.
• Agitator Circuit Breaker (Fig 6) The circuit breaker
automatically opens and protects the entire machine
from damage caused by overloading the agitator/
airlock components, low voltage, short circuits or
dropping foreign objects into the hopper/base.
• Main Circuit Breaker (Fig 6) The circuit breaker
automatically opens and protects the entire machine
from damage caused by overloading the machine, low
voltage, short circuits or dropping foreign objects into
the hopper/base.
• Hour Meter (Fig 6) Displays the total number of
hours used. It is also used to indicate when regular
preventive maintenance is due.
•“On” Button (Fig 7) This push button switch is
colored green and turns the entire machine “on.”
•Ready Light (Fig 7) This white indicator light allows
the operator to visually see when the machine is ready
to use. It will not illuminate if the following conditions
exist: agitator or main circuit breaker is tripped or is
not depressed in the “on” position, GFCI is tripped or
electrical power is not present at the electrical inlet of
the machine.
• “Off” Button (Fig 7) This push button switch is
colored red and turns the entire machine “off.”
This switch also can be used in an emergency and
overrides the wireless remote.
• Wireless Remote & Holder (Fig 8) This feature is
part of the control system and allows the operator
in the attic to turn “on” and “off” the machine via a
wireless signal. The green push button turns on the
entire machine and the red push button turns it off.
The indicator light at the top of the wireless control will
illuminate when either button is depressed, signifying
that the batteries are in good condition and the signal
has been sent to the machine on the ground.
The wireless control can operate up to 250' depending
upon the location of the machine and the construction
of the structure being insulated. If you experience
difficulties with the wireless system, you may need to
change the batteries in the transmitter or locate the
machine to another area where the signal is better.
The transmitter (attached to the hose) uses two (2) AA
batteries. To replace the batteries, the holder must be
removed from the hose.

SETUP
Before the machine will operate, the hopper must be oriented and securely fastened as shown (Fig 9-10).
Next, attach the two 50', 2.5" sections of hose to each other, then to the machine – using the quick connect
(Fig 10). Attach additional sections of hose using the supplied hose connector and hose clamp.
NOTE: You may only connect up to a maximum of 100' of hose.
Attach the special (twist lock) power cord to the electrical inlet by aligning the blades and twisting in a clockwise
motion until it stops. Plug the other end of the power cord into a dedicated 115 VAC 15 amp grounded outlet.
Refrigerator or freezer outlets usually fit the requirements. If necessary, these appliances can be temporarily
unplugged, enabling the TrueComfort machine to run on sufficient power.
Note: Never transport the
machine in an open truck while
hopper is attached. Failure to follow
this warning may cause the hopper
to come off while driving.
Use a 115 VAC 15 amp
household outlet

At this point you should have the hopper attached, a 50' power cord plugged into the machine and a 115 VAC 15
amp household outlet, and 100' of 2.5" blowing hose attached to the outlet of the machine.
Note: The attic should be prepared before any insulation is added.
Contact your local building code department for further details.
Next, run the 100' of 2.5" hose into the attic and to the furthest point. Next, locate the circuit breaker on the base
of the machine and depress to the “on” position (Fig 11). Once the main circuit breaker has been depressed the
“READY LIGHT” on the operator panel will illuminate indicating the machine is ready for use (Fig 12).
NOTE: If the ready light does not illuminate, check to make sure the hopper is on correctly and the power cord is
supplying power to the machine. When power is present the LED will illuminate.
SET-UP IS COMPLETE AT THIS POINT
OPERATION
Operator Panel
The electrical control of the TrueComfort machine has been designed with the latest technology to allow the
operator full control of the machine at either the ground or in the attic. The operator panel has two push buttons
for the “on”/ “off” function and a ready light to let the operator know when the machine is ready for use (Fig
13). When the green push button is depressed it will first start the blower, then 3-5 seconds later it will start the
agitator. To stop the entire machine (blower and agitator), depress the red button.
NOTE: You cannot run the blower or agitator independently of each other!

LOADING THE MACHINE
Always use caution when cutting bag open.
Using a long-bladed knife, cut packages in half according to the instructions on the package. Cut about one-
quarter of your total number of packages to start, and stack the rest near the machine for easy access (Fig 14).
The process of feeding insulation into the blowing machine is fairly simple, but there are a couple of key points
to be aware of when loading.
Place one of the package halves onto the hopper tray (Fig 15-16) and align the green dotted line with the knife
slot. It’s important to note that the open part of the bag should be facing to the left or right and never into the
hopper; when positioned this way, the arrows will point into the hopper and the green dotted line will match up
with the knife slot. Remember: NEVER position the open end of the half-package facing into the hopper.

TrueComfort System
Setup and Operation continued
Insert the knife into the slot and slit quickly across the entire package from left to right (Fig 17-18). Be aware
that the compressed insulation will expand quickly into the hopper opening. It is best if material feeds into the
machine evenly.
While feeding the insulation into the machine, pull the bag out. DO NOT LET THE BAG FALL INTO THE
MACHINE. DO NOT OVERLOAD/STUFF THE MACHINE, or it will shut off. Feed the next half-package into
the machine when you can see the “add more” line inside the hopper. Repeat the above steps until the job is
complete.
Note: Periodically, it may be necessary to push or nudge the insulation sitting on the shelf into the hopper.
Additional troubleshooting information can be found beginning on page 19.
Note: The amount of insulation you blow into the attic depends on the R-value, or level of
insulating performance you wish to achieve. The higher the R-value number, the better the thermal
performance – and the thicker the layer of TrueComfort insulation, the higher the R-value will be.

TrueComfort System
Generators and Extension Cords
The TrueComfort System will operate on power from a commercial-sized generator. No household generators
should be used due to the high inrush requirements of the TrueComfort System. Also, generators made by
Honda, Yamaha, Coleman and Generac are not recommended. While they are of high quality, these generators
do not have the inrush protection devices necessary to start the TrueComfort System and protect the generator.
The start-up requirement for a TrueComfort System is 3450 watts; normal operating requirement is 1725 watts.
We recommend a generator of not less than 4000 watts, 115 VAC.
In addition, CertainTeed recommends generators that have a 50% power boost feature which aids the generator
in high current start-ups. Running additional equipment from the same generator will increase the total electrical
requirements. Before selecting the correct size of generator, add up all tool wattages including the TrueComfort
System. For details on selecting and purchasing a generator, please call CertainTeed Machine Works.
Note: Using a generator of insufficient size will void the Warranty.
If additional length is required – beyond the supplied 50' power cord – see table below for adding an extension
cord. Use only those extension cords meeting these specifications. Always use a 3-conductor extension cord.
