WARNING: APPLY THE APPROPRIATE WATER PRESSURE
AND TEMPERATURE TO ALL FITTINGS TO PREVENT
LEAKAGE AND COMPONENT FAILURE
ATTENTION: SYSTEM MUST BE INSTALLED IN CONDITIONED SPACE BETWEEN 32°F AND 130°F
Ensure there is 36 Inches of service clearance to the front of the panel.
Plumbing Connections for Self Cleaning
Several field plumbing connections are required for proper Self Cleaning hood operation. It is
recommended that all plumbing connections be sealed with Teflon tape or pipe thread sealant. Use care
not to contaminate the interior surfaces of the water lines when plumbing the unit, as small particulate can
clog the orifices of the spray nozzles.
1. All incoming plumbing connections are connected via ¾” quickseals at the top of the utility
cabinet. See Figures 1 and 2 for details.
2. Self Cleaning hoods with the W1 option (Hot Water Wash) require a hot water connection at
140°F to 170°F and a minimum required PSI, per Table 1, to 50 psi operating pressure. If the
operating pressure is greater than 50 psi, a water regulator must be connected. Max water static
pressure is 125 psi. Typical water flow rate is 0.7 GPM per foot of hood. The spray lasts for a
factory setting of 3 minutes every time the fans are switched off.
3. Self Cleaning hoods with the W2 option (Constant Cold Water) require an unheated water
connection at an operating pressure of 10 to 20 psi. If the pressure is greater than 40 psi, a water
regulator must be connected. Max water static pressure is 125 psi. Typical water flow rate is 0.4
GPM per foot of hood. The spray runs constantly while the fans are turned on.
4. Self Cleaning hoods with the W3 option (Hot Water Wash and Constant Cold Water) require a hot
water connection at 140°F to 170°F and a minimum required PSI, per Table 1, to 50 psi operating
pressure and an unheated water connection at 10 to 20 psi operating pressure. If the pressure is
greater than the max rating, a water regulator must be connected. Max water static pressure is
125 psi. Typical water flow rate is 0.4 GPM per foot of hood for cold water and 0.7 GPM per foot
of hood for hot water. The cold spray runs constantly while the fans are turned on and the hot
water lasts for a factory setting of 3 minutes every time the fans are switched off.
5. If multiple hoods are arranged in an end-to-end or back-to-back arrangement, plumbing
connecting the hoods must be piped in the field. The plugged end of the spray bar is used to do
this. Remove the plugs on the main hood and the adjacent hood and simply pipe the two
together.
6. There is also a non-pressurized 1-1/2 inch drain connection that must be piped. This allows
water to drain from the hood grease trough. It must be connected to the building grease trap.
Hoods 10’ in length (or greater) will require 2 drains. 24” tall hoods with 20” filters will require 2
drains. All other hoods will require 1 drain. See Figure 3 for details.
7. Once all supply and drain lines are connected, remove one of the nozzles and flush the lines.
8. The Ansul fire system duct detection bracket and fusible link are shipped loose to be installed in
the exhaust ductwork. The detector must be installed no more than 20 feet from the hood, and
installed per the Ansul fire system guidelines.
Warning
All field connections between hoods and drain lines must be run with Steel, Stainless Steel, or
Copper pipe. Plastic pipe cannot be used for drains or field connections between hoods, as it
could fail and become hazardous.
