Cold Weather Protection
Winterize machine when stored below 32 degrees F by following these steps:
Your machine can also be protected from freezing by using non alcohol based anti-freeze as follows:
Method 1
— Use pressurized air to blow out any remaining water left inside pump and hose by using the air blow-out
feature (see page 12).
Method 2
— Drain tank completely.
— Add 50/50 mix anti-freeze to tank as follows:
0° - 4 gal.
-30° - 6 gal.
— Remove nozzle and feed reel jetting hose into tank, open reel valve.
— Start engine and circulate water through system for 1 minute.
— Close reel valve and discharge water through gun and 1/4” hose if necessary.
— Check freeze protection of mix with tester and add more anti-freeze if necessary.
— Replace nozzle and hose.
Note : Some anti-freeze mixture can be caught and reused, but will have to be strengthened as necessary for adequate
protection.
Venturi Pump Attachment- 77763700 (Optional)
How the Venturi Effect works.
The venturi effect uses the venturi pumping attachment and your Spartan Jetter to create
a vacuum effect to drain standing water. In Fig. 9, the black circles represent water
from the jetter and the white circles represent the water to be pumped. The venturi has
two parts: the Venturi Throat, which is a restricted section of the suction tube; and
above that is the venturi itself which is the part where the tube widens and connects to
the discharge hose. The water from your Spartan Jetter is accelerated through a venturi
restiction which causes it to increase speed causing a pressure drop and creates the
vacuum that sucks in more water at the base of the attachment.
Venturi Pumping Attachment Operating Instructions
1. Attach high pressure hose directly to the suction head of the venturi attachment.
2. Lower suction head into water or liquid to be pumped. The discharge hose is 15 ft.
long and this determines the maximum depth or distance liquids can be pumped.
3. At a depth of 15 ft., the venturi attachment will pump 35-40gpm. If additional lengths
of discharge hose are added, the pumped volume will decrease accordingly.
4. Be sure to keep the pumping head submerged at all times to ensure steady, continuous
operation.
5. Start engine and bring jet to full pressure. Use the ball valve on high pressure hose
reel to control venturi operation.
