NOTIFY CARRIER OF DAMAGE AT ONCE.
It is the responsibility of the consignee to inspect the
container upon receipt of same and to determine
the possibility of any damage, including concealed
damage. Avtec suggests that if you are suspicious of
damage to make a notation on the delivery receipt.
It will be the responsibility of the consignee to file a
claim with the carrier. We recommend that you do so
at once.

I. General Description
The AVTEC PAWS panel is supplied as a Sub-
Assembly for an AVTEC Energy Aire Auto Wash
Ventilator.
The PAWS panel is provided to control the
exhaust and make-up air fans and the Ventilator
Auto Wash (cleaning) cycle(s).
One panel will control one or more fans if
operated simultaneously.
operate up to 50 linear feet of ventilator with a
single wash output. Sequential wash models
include up to 8 wash outputs and can operate
up to 400 linear feet of ventilator.
Fan and wash operation may be initiated
manually or programmed to occur at a user
specified time. The operation of the wash
output(s) may be set to a value from 2 to 10
minutes.
The PAWS panel may be provided as a wall
mounted unit or integrated into an AVTEC
Energy Distribution System (EDS).
Underwriters Laboratories Inc. (UL) list the
PAWS panel as:
“SUBASSEMBLY FOR EXHAUST HOOD
WITH EXHAUST DAMPER, for USE ONLY
WITH AVTEC LABELED HOOD

EXHAUST DAMPER”
“SUBASSEMBLY FOR EXHAUST HOOD
WITHOUT DAMPER, for USE ONLY WITH
AVTEC LABELED HOOD ASSEMBLY
FOR EXHAUST HOOD WITHOUT
EXHAUST DAMPER”
All support plumbing and electrical components
for the PAWS panel are located within the panel
or the EDS. Peripheral plumbing components
may be shipped loose for installation in the field
by appropriate trades.

4. Vent Exhaust Damper Switch
(optional feature)
The hoods connected to the panel may
include exhaust dampers with switching
devices that indicate when the damper
has closed due to an extreme
temperature rise. There are three types
of exhaust damper that may connect to
the PAWS panel, Resetable ElectroMechanical, Fusible Link with Thermoswitch, and Fusible Link with damper
switch.
a) Resetable Electro-Mechanical

The connection is from the PAWS
panel to the hood connection box.
Terminal #7 provides power to the
common terminal on the relay.

5. Water Solenoid
The water wash solenoid is installed and
pre-wired in panels that have a single
wash output.
Water wash solenoids for multiple wash
output panels are pre-mounted on the
hood. The installing electrician must
provide a (2) wire circuit from the panel
terminal strip to the each solenoid valve.
Terminals #22 through #29 are provided
for each wash output

6. Fire Pull Switch (optional feature)
The Fire Pull Switch is an optional
feature that allows the user to activate
the PAWS Fire Condition manually. The
pull switch may be panel mounted and
pre-wired, or installed in a remote
location (typically at the egress of the
kitchen). The normally closed switch is
connected to Terminals # 2 and 3. The
panel is shipped with a jumper between
these terminals. The jumper is removed
and discarded once the Fire Pull Switch
is connected. Terminal

7. Detergent Pump
The Detergent Pump is installed and
pre-wired in panels that have an integral
Detergent Tank.
Some applications use a remote
Detergent dispensing cabinet with a
large volume tank (5 gallons) or drum.
In these applications the pump is
provided in a stainless steel cabinet.
The installing electrician must provide a
(3) wire circuit from the panel terminal
strip to the Detergent Pump. Terminal
#9 is connected to the normally open
contact on the pump prime switch,
terminal 21 is connected to the normally
closed contact on the prime switch. The
neutral lead from the pump motor is
connected to the “N” terminal strip. See
Figure II.B.7.

8. Detergent Probe
The Detergent Probe is installed and
pre-wired in panels that have an integral
Detergent Tank.
Some applications use a remote
Detergent dispensing cabinet with a
large volume tank (5 gallons) or drum.
In these applications the probe is
connected to a terminal strip in the
Detergent Pump steel cabinet. The
installing electrician must provide a (2)
wire circuit from the panel terminal strip
to the Detergent Probe. See Figure
II.B.8.
Figure II.B.8
The probe should be installed in the
detergent container so that it does not
protrude below the top of the detergent
pump inlet strainer. This is intended to
prevent the pump from losing its prime
and will advise when the tank needs to
be refilled. The probe rods may be cut
to facilitate a neat and effective
installation. See Figure II.B.8.a.
