Installation
5.
Flush the Heater
WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
follow the
Pressure Relief Procedure
on page 6 before flushing the heater or
spray system and whenever you are instructed to
relieve pressure.
WARNING
FIRE AND EXPLOSION HAZARD
Before flushing, disconnect the electrical
power to the heater to reduce the risk of
static sparking, which can cause fire or
explosion.
CAUTION
The heater was tested in lightweight oil which was
left in to protect the parts during shipment. The oil
must be flushed or purged from the system to avoid
material contamination.
NOTES
1.
Use a solvent that is recommended by your mate-
rial supplier, and be sure it is compatible with the
heater’s wetted parts.
2.
Some material will be contaminated whether you
simply purge the oil from the heater or use a
solvent to thoroughly flush. Discard that material.
3.
For long term shutdown or storage, flush with a
compatible solvent and then flush with a light-
weight oil. Leave the oil in the system to protect it
during shutdown.
4.
Some material suppliers provide maintenance
services which include flushing and storage.
5.
Never flush the hoses. It is very difficult to remove
all moisture from hoses which have been flushed,
and the moisture will contaminate the ISO and
RES.
Procedure
1.
Relieve the pressure.
2.
Disconnect the material hoses, if connected.
3.
Remove the outlet fittings (X) from both fluid filter
outlet nipples (114).
4.
Plug each outlet nipple (114) with a swivel (P/N
156173) and plug (P/N 101754). These parts are
shown exploded on the left side of Fig. 4 and
assembled on the right side of Fig. 4.
5.
Connect your flushing system supply hose to the
IN port of one of the heaters.
6.
Open the filter drain valve (111). Have a waste
container ready to catch the draining solvent.
7.
Turn on the flushing system and use the lowest
possible pressure to flush the heater for several
seconds.
8.
Shut off the flushing system and close the drain
valve.
9.
Repeat this procedure for the other side of the
heater.
10. Continue the setup by connecting the electrical
service. When you are ready to prime the system,
the procedure on page 14 tells how to purge the
remaining solvent from the heater.
