This product must be grounded. In the event of an elec-
trical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric cur-
rent. This product is equipped with a chord having a
grounding wire. A 3-blade grounding plug must be
installed or the machine may be hard wired. The plug
must be plugged into an outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
Install Plug
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by provid-
ing an escape wire for the electrical current due to
static build up or in the event of a short circuit.
Improper installation of the grounding plug is able to
result in a risk of electric shock. The wire with insula-
tion having an outer surface that is green with or with-
out yellow stripes is the grounding wire.
Improper installation of the grounding plug is able to
result in a risk of electric shock. The wire with insulation
having an outer surface that is green with or without yel-
low stripes is the grounding wire. Do not modify the plug
provided; if it does not fit the outlet, have the proper out-
let installed by a qualified electrician. Only connect the
product to an outlet having the same configuration as
the plug. Do not use an adapter with this product.
2. For machines that will not be hard-wired, install a
3-blade 240V, 1-phase grounding plug onto
cord (129). The machine must use a receptacle that
accepts the plug on the product.
Installation
For machines that will be hard-wired, hard-wire
the machine. The grounding wire must be used.
Connect Electrical Cord
Machine may be hard-wired or installed using a
plug.
Improper wiring may cause electric shock or other
serious injury if work is not performed properly. Have
a qualified electrician perform any electrical work. Be
sure your installation complies with all National, State
and Local safety and fire codes.
1. Each machine comes with a permanent 10 ft power
cable without a plug. If a permanent extension cable
must be installed onto the existing cable or if an
extension cord is necessary, be sure to use the

Install Low Power Temperature
Control Modules
The low power temperature control modules are
installed in the Heat Control box at the factory. If a low
power temperature control module must be replaced,
perform the following procedure.
9. Change rotary switch position on new low power
temperature control module. See Adjust Rotary

Installation
There is one breaker for each heated hose or heated
tank. The lower number breakers are used for the
there are two heated tanks installed and two heated
hoses, breakers #1 and #2 are used for the heated
tanks and breakers #3 and #4 are used for the heated
hoses. If there is one heated tank and one heated hose,
then breaker #1 is used for the heated tank and breaker
#2 is used for the heated hose. Each breaker has a dif-
ferent rating so it is important that the correct breaker is
used.
Set the rotary switch (S) to the specific selection accord-
ing to the settings listed in the following table.
Low Power Temperature Control Module
Rotary Switch Location
The 3-wire module power is connected in the Heat Con-
trol box at the factory. The power cord (118) for each low
power temperature control module has a connector on
one end and three power leads on the other. The three
power leads must be connected to the appropriate
breaker (114) and ground terminal (116).

2. Connect the green wire to any unused ground termi-
nal block (116).
3. Find the breaker with the same number as the mod-
page 9.
The modules must always be set to the zone num-
ber shown on the label above the module.
4. Connect the black and white wires to the
breaker (141) labeled with the same number as the
module. The black and white wires can connect to
either terminal (141a) in the same breaker (141).

The rotary switch setting indicates which zone number
the low power temperature control module will control in
the system. The low power temperature control module
uses a 16-position rotary switch.

Graco Ohio Standard Warranty
Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing its name to be free from defects in
material and workmanship on the date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty
published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by
Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty
installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of
non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with
structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or
maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of
the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned
to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will
be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy
(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or
consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these
warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or
