1. Remove the tank head assembly by unscrewing
the three Tek screws and lifting the tank head off.
2. Remove the two pipe nipples and associated fit-
tings.
3. Lift the coil out of the outer wrap.
CAUTION: The coil weighs about 80 lbs. Use proper
lifting techniques.
4. Clean, repair and replace the coil by reversing the
above steps.
pressure relief valve:
Each machine is equipped with a relief valve to relieve
pressure in the system when higher than normal oper-
ating pressures are encountered. Unusually high pres-
sures come from an object plugging the spray nozzle.
This problem can easily be remedied by removing the
obstruction. If operating pressure of machine is found
to be normal and relief valve continues to leak, repair
or replace the valve.
rupture Disk
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst, allowing
high pressure to be discharged through hose to ground.
When disk ruptures, it needs to be replaced.

propane Cylinder Capacity:
An important consideration with propane systems is the
capacity of the supply cylinder relative to the needs of
the burner. The burner operates on propane as a gas;
as gas is used from the propane cylinder, the liquid in
the cylinder boils to maintain gas pressure. This boiling
process cools the liquid, and in a heavy, continuous-
demand situation, the liquid temperature can fall to
the point at which it cannot provide gas as rapidly as
is needed. In this case, it may be necessary to warm
the propane cylinder by directing a warm spray, not
over 120° F, on the cold cylinder or by manifolding two
propane bottles together to increase total vaporization
capacity. It is recommended that a minimum 30 lb.
vapor propane bottle be used on the machine.
