TROOPER : Negative Pressure System
backwards. Instead, reverse the ‘TO MOLD’ and ‘FROM MOLD’
connections and allow the water to flow through the mold in the
opposite direction. However, it should be kept in mind that operating
the mold with this set-up may result in less than optimum pressure
drop across the mold. See section 4.1, “How a TROOPER works”
on page 15.
5.10 UNIT LEAKS AT PUMP OR MOTOR HOUSING
A.
AT MOTOR:
1.
If the bolts that hold the pump housing to the motor
assembly are tight, and it is still leaking, the seal may be
damage and should be replace. See section 6.2: “Parts
Failure - common causes” on page 29.
B.
AT PUMP:
1.
If unit leaks between pump halves and bolts are tight, stator
may be damaged and should be replaced. See section 6.2
“Parts Failure - common causes” on page 29.
5.11 HOSE COLLAPSES
A.
Use a hose that is rated for vacuum and temperature. Be sure that
there are no sharp turns or loops in the hoses.
5.12 WATER DRAINS CONSTANTLY FROM VENT LINE
A.
On the TR-100, TR-200 and TR-300:
1.
The mechanical float or needle valve inside the air vent
may have become clogged with sediments or worn from
use. If cleaning does not solve the problem, replace the
vent.
B.
On the TR400 and TR500:
1.
Either the electrical float switch inside the tank or the vent
solenoid is stuck. Either may have become clogged with
sediments or worn from use. They should be disassembled
and cleaned.
2.
Tapping the side of the tank with a rubber or plastic
hammer may dislodge sediments or mineral deposits and
restore movement to the float. However, this is only a
temporary fix. The float assembly should be removed and
cleaned. See appendix “electrical float switch assembly”.
