C. Plumbing Interconnection
A project specific drawing is provided in the
project installation package that lists specific
connections required, and components that
are supplied by AVTEC.
Individual field interconnections are listed
below.
1. Hot Water Supply
140oF (minimum) hot water, 20-40 psig
is needed to properly clean the extractor
chamber. The Hot Water Supply is
connected to the control panel inlet. A
pressure reducing valve may be
required if water pressure exceeds 60
psig. Refer to your project drawing for
the pipe size required. Typical water
consumption at 30 psig is 1.2 gallons
per minute per linear foot of hood. For
example a 10’-0” long hood would
require 12 gallons per minute. Refer to
Figure II.C.1.
2. Hot Water from Panel to Hood Inlets
Hot water piping is required from the
panel outlet to a vacuum breaker-check
valve-detergent injection tee assembly.
NOTE:
Panels with a single wash output
(water solenoid mounted in the
panel) require an atmospheric
vacuum breaker, mounted at least
6” above the hood inlet.
Panels with multiple wash outputs
(water solenoids mounted on hood
sections) require a pressure type
vacuum breaker, mounted at least
18” above the hood inlet.
The vacuum breaker-check valve
assembly is provided by AVTEC
when specified. Refer to your
project drawing.
Additional piping is required from the
vacuum breaker, check valve, and
detergent injection tee assembly to the
Hood water inlet(s). AVTEC will pre-
pipe multiple hoods to a single inlet
when specified. Refer to your project
drawing for hood inlet connection
requirements. Refer to Figure II.C.1.
3. Cold Water Mist Supply (optional
feature)
When specified, the Cold Water Mist
feature is provided to add an additional
level of grease extraction. The Cold
water mist operates whenever the
Exhaust Fan is running.
The cold water supply (20-30 psig) is
connected to the control panel inlet. A
pressure reducing valve may be
required if water pressure exceeds 30
psig. Refer to your project drawing for
the pipe size required. Typical water
consumption at 30 psig is 0.6 gallons
per minute per linear foot of hood. For
example, a 10’-0” long hood would
require 6 gallons per minute. The Cold
Water Mist manifold is constructed the
same as a single wash Hot Water
manifold. Refer to Figure II.C.1.
4. Cold Water from Panel to Hood Inlet
Cold water piping is required from the
panel outlet to a vacuum breaker-check
valve assembly.
NOTE:
An atmospheric vacuum breaker,
mounted at least 6” above the hood
cold water inlet is required.
The vacuum breaker-check valve
assembly is provided by AVTEC when
specified. Refer to your project drawing.
Additional piping is required from the
vacuum breaker-check valve assembly
to the Hood water inlet(s). AVTEC will
pre-pipe multiple hoods to a single inlet
when specified. Refer to your project
drawing for hood inlet connection
requirements. Refer to Figure II.C.1.
