Transcal - Goldacres MY17-19 Operator's Manual

Transcal

PROBLEM
Transcal is not working or is
working too slow?
The Transcal tank has
deformed and sucked in?
The sight tube on the Transcal
is not giving a true indication
of the tank level?
ISOLATING POSSIBLE AIR LEAKS
Step 1: First check the operation of the chemical
probe only i.e. bypass the Transcal tank. If it is found
to transfer water at a minimum rate of 30L/min, then
this part of the system is okay.
If not, check for air leaks at:
• Cam lever fitting at the probe.
• Hose fittings.
• Venturi – the venturi can suck air (less vacuum)
where the black drop-pipe connects to the
orange venturi.
• The venturi may also suck air where the 'lay flat'
hose joins the bottom of the black PVC drop
pipe.
Step 2: Check Transcal tank. If the probe is working
successfully but the Transcal tank system won't work
then the air leak areas to check are:
• The Tank lid. This lid may tighten against the metal
bracket above the tank and not the tank itself.
Also the top of the tank needs to be clean and
smooth for the lid to seal. Also check the lid for
cracks and condition of the seal.
• Fitting at the base of the Transcal tank.
• Any hoses and connectors.
Step 3: If probe works correctly and Transcal tank
works correctly when using suction probe but
envirodrum will not operate, check for air leaks in
envirodrum fitting (this must be thoroughly cleaned
after each use) and check interior pipes in the
envirodrum for air leaks or damage.

COMMON CAUSES
Air leak in the vacuum system
The volume of water supplied
to the Venturi
Residual vacuum left in tank
when it is not in use. This is
especially important when
spraying in warm weather or
when the sprayer is parked
overnight.
Probe or envirodrum couplers
turned on
COMMON SOLUTION
Check all hose clamps and fittings are tight
Check there are no kinked hoses and the
water pressure is about 100psi
When use of the Transcal is complete,
make sure the venturi probe tap is turned
off and let the tank vent.
Ensure the tap on the Probe or
Envirodrum coupler is turned off before
evaluating the tank level.
SUMMARY
Check the flow of water into venturi and then:
1. Check the probe only.
2. Check the probe and Transcal.
3. Check Transcal and envirodrum section.
NOTE:
• Tests must be done with water because the
speed of the transfer is affected by chemical
viscosities.
• Do not remove drop pipe from venturi except
for resealing.
