Hydro Tek HG SERIES, Operation & Maintenance Manual

Page: 6 / 24

BEFORE START UP:
1. Read all instructions before using this product.
2. CHECK OIL AND FLUID LEVELS:
Check pump oil by locating the oil view
window or dipstick and fill to the red
dot. Check fuel levels.
Check engine oil and
coolant levels if unit is
so equipped. (See the maintenance schedule
on page 16).
3.
CONNECT HOSE AND GUN
ASSEMBLY.
4.
CONNECT THE WATER SUP-
PLY & TURN
WATER ON:
Maintain an adequate supply of water using a ¾"
I.D. hose with a pressure between 25 and 60 PSI. Burner
power switches should be off before starting. If tank fed,
be sure there is water in the tank and the valve is switched
for supply tank feed. Do not run dry for longer than one
minute.
5. BATTERY INFORMATION
If you did not order a battery with your machine you
will have to buy one and fill it with electrolyte (avail-
able at local auto parts store).
!WEAR EYE PROTECTION!
If the opening on your battery box
measures 9" by 6" we
recommend Exides'
U1L/GTH 235CCA
battery. If the opening
measures 8" by 12" we
recommend Exides' group 46-60 550 CCA battery. Deep
cycle batteries are recommended to extend battery life.
Always connect the positive battery cable before the
negative and coat the battery terminals with corrosion
inhibitor to prevent corrosion.
6. If wheel kit, accessories, or discharge hose are not
installed, see your local dealer for instructions & installa-
tion.
OPERATION:
1. STARTING:
A. Electric Powered Units:
Connect power supply and ensure that all wiring connec-
tions and voltages are of sufficient rating to comply with
the equipment's requirements. Turn pump power switch
on. If unit is equipped with auto-start, keep all power
switches off when left unattended. (Unit will only turn on
when trigger gun is pulled.)
B. Gasoline Engine Units: To reduce the risk of starter
damage remove spray nozzle from wand and pull spray gun
trigger while cranking engine. After start, release trigger and
replace spray nozzle. Be sure nozzle is properly positioned
in quick disconnect before spraying:
2. PURGE AIR FROM SYSTEM:
Squeeze the trigger on the spray gun until a constant stream of
water comes out. (Purging works best with nozzle removed
from wand and/or dual wand in the low pressure mode.)
3. SELECT DESIRED
NOZZLE
Connect nozzle securely
to spray wand. If equipped,
close pressure adjusting
knob on dual wand. Hold gun firmly, squeeze trigger for
high pressure spray. O-ring should be replaced with 1/4"
or 3/8" EPDM.
CAUTION - Gun kicks back - hold with both hands.
WARNING - Risk of explosion - DO NOT spray
flammable liquids.
4. START BURNER: To create hot water on high pressure
washers equipped with heat exchangers, release the trigger
on the gun, turn the burner to the on position, and turn the
thermostat to the desired temperature.
Squeeze the trigger on the spray gun and the burner will
begin heating the water. It will stop firing whenever the
water spray is off or if the temperature setting is ex-
ceeded.
5. STEAM: (If Equipped)
Insert steam nozzle and turn thermostat to 250º steam
setting. The steam nozzle is sized for approximately
25% less water volume than the hot water mode.
6. BYPASS MODE:
System will go into bypass mode when machine is left
running and trigger gun is closed. Bypass mode is when
the inlet water coming into the pump recirculates through
the unloader across the pump head. If left in bypass too
long - More Than Five Minutes - friction created by the
movement of the water will begin to heat the water at a
rapid rate. If equipped with a THERMAL DUMP
VALVE, water exceeding 145°F will cause the valve to
open allowing the hot water out of the system into the
atmosphere and allow cool water in. The valve
will reset itself when water temperature comes
down to a safe level.
If equipped with a bulk water tank, water can be
bypassed back through the tank allowing for a
larger volume of water to be recirculated through the pump
head thus reducing heat on the pump seals.
!Warning: Do not leave in bypass for longer than five
minutes to prevent pump from overheating.
