Hallett 30 1” Instruction Manual

Step 6: Caution: do not allow the inside of the unit to get wet. Before

opening the water supply, double check all connections and cover the top of the

unit with a rag or some plastic to prevent water entry. Close any faucets you

opened in Step 1 and then slowly turn on the water supply to check for leaks. If

leaks exist, investigate the cause and repair. Caution: Do not connect the unit to

electrical power until the piping and unit are free of water leaks. The solenoid

valve can be placed into manual mode to allow water to enter the unit. Switch

back to automatic mode when done.

Step 7: Once the system is checked for leaks under full system pressure, install

pipe insulation on the outlet hose and piping to prevent condensation from falling

onto or into the unit.

In extended periods of no flow conditions, water temperatures will rise

which may lead to the precipitation of minerals and/or decreases in water

quality. To avoid this, the installation of a purge valve assembly (p/n

X500000) is recommended. Contact your water treatment professional for

consultation.

Parallel Installation

When more than one unit is installed in parallel (flow split between units), the

units must be installed with manual shutoff valves both upstream and

downstream of each unit. This allows one unit to be serviced without interrupting

the flow to the other units. Another requirement is the installation of a check valve

downstream of the unit (after the unit). This will prevent the backflow of water to a

unit. See Figure 1E.

Plugging in the Hallett

Step 1: Ensure that the covers on the unit have been installed and the unit is

securely fastened to the wall. (Note: You should not remove any cover unless

the unit has been unplugged).

Step 2: Plug the female end of the power cord into the power entry module

located on the underside of the front panel. Note that the power entry module

contains the only fuse for the unit, which can be accessed by pulling out the

sliding fuse drawer. The power cord must be removed before changing the fuse.

See Figure 1B

Connect the male end of the system’s power cord into the Transient Voltage

Surge Suppressor, and connect the Transient Voltage Surge Suppressor to a

GFCI (live and neutral wires must be correctly wired within receptacle).

Important: after the unit has been operating for a few hours, unplug the unit and

check all hose connections for leaks (the top hose in particular). Repeat this

procedure periodically.

Proceed to system operation for further instruction to ensure optimal

performance.
