Dual Lance Assembly With Adjustable Pressure; Water Supply - Mi-T-M HSD Serie Manual Del Usuario

INSTALLATION & PREPARATION

DUAL LANCE ASSEMBLY WITH ADJUSTABLE PRESSURE:

This unit features a Dual Lance Assembly with adjustable pressure which
allows the user to select a high or low pressure "fan" spray. Simply rotate
the adjustable grip on the dual lance to achieve the desired pressure
selection.
1. Selection of high pressure can be achieved by turning the adjustable grip
on the Dual Lance assembly counterclockwise as shown in the figure
below.
2. Selection of low pressure detergent application can be achieved by turning
the adjustable grip on the Dual Lance clockwise as shown in the figure
below. Once the pressure is low enough, the detergent injector on the
pressure washer will draw detergent into the system. A water/detergent
mixture exits from both the spray nozzle and detergent nozzle.
DUAL LANCE CONNECTION:
1. Be certain the trigger gun is locked in the "OFF" position.
2. Connect the dual lance assembly to the trigger gun assembly at this
time (if applicable). Be certain the connection is securely tightened.

WATER SUPPLY:

1. Select a water supply hose which is a quality grade of garden hose
measuring at least 3/4" ID and no longer than 50'.
2. Check the water inlet strainer to ensure it is clean and free of any
obstructions. As a strainer becomes obstructed, it restricts proper flow
of water to the pump. This can result in cavitations which will cause
premature failure of pump packings.
a. Unscrew the strainer cap from the unit.
b. Remove the strainer screen and clean or replace.
3. Connect one end of the water supply hose to the water inlet of the unit.
Connect the other end of the hose to your pressurized water supply.
NOTE: If there is a high mineral content in your water, it is recommended
that a water softener be used to prevent the possibility of excessive
scale buildup inside the heat exchanger coil.
4. Follow the incoming water requirements listed below:
a. Water pressure must be between a minimum of 20 pounds per square
inch (PSI) and a maximum of 125 PSI.
b. Incoming GPM must be approximately one gallon more than the
outgoing GPM stated on the pressure washer nameplate.
(You can check GPM by timing how long it takes to fill a 5 gallon
container)
c. Incoming water temperature must not exceed 125°F. Excessive
pump damage may result if the water temperature exceeds this
acceptable level.
5. Never allow the unit to operate without the incoming water line attached
and the water supply completely turned on.
