Ensure you have reads the above section entitled “PLUMBING THE MACHINE” above
before proceeding. Install the HTS-11 into the water line (1/2” ID pipe size minimum)
before the dish machine line incoming water connection point using copper pipe. The
HTS-11 must be installed vertically. A mounting bracket is provided to facilitate the
venture metering head to the wall. Observe proper inlet/outlet water directions. Flow
directions are molded into the top of the head. It is recommended that a water shut
off valve be installed before the HTS-11 to allow access for servicing. Plumb from the
HTS-11 outlet to the incoming water connection point using copper pipe (or order the
1/2” ID exible hose kit offered by Noble). The water supply is to be capable of 20 PSI
(plus or minus 5 PSI) “ow” pressure at the recommended temperature indicated on
the data plate. See “Shock Absorber” section.
Ensure you have read the section entitled “PLUMBING THE DISH MACHINE” before
proceeding. Install the water supply line (1/2” ID pipe size minimum) to the dish ma-
chine incoming water connection point using copper pipe (or order the 1/2” ID exible
hose kit offered by Noble). It is recommended that a water shut off valve be installed in
the water line between the main supply and the machine to allow access for service.
The water supply line is to be capable of 20 PSI (plus or minus 5 PSI) “ow” pressure
at the recommended temperature indicated on the data plate.
Upon rst installation, the chemical alarm will buzz until the chemical feeder pumps
are primed. If the chemicals run out, the chemical alarm will buzz until the chemical
is replaced and primed if necessary. The bottom of the chemical container cannot be
located any higher than 8” from the oor. If the unit is shipped with a 6” or 18” table
stand, then the highest position will be respectively 14” or 26” from the oor.
Noble offers a water pressure regulator that can be purchased separately. Regulators
help areas where the water pressure uctuates or is lower than the recommended
pressure. DO NOT confuse STATIC pressure with FLOW pressure. Static pressure
is the line pressure in a “no ow” condition (all valves and services are closed). Flow
pressure is the pressure in the ll line when the valve is opened during the cycle.
Also, it is suggested that a shock absorber (NOT SUPPLIED) be installed on the
incoming water line. This prevents water hammer (hydraulic shock), induced by the
solenoid valve as it operates, from causing damage to the equipment.
