Daily Start-up Procedure

NOTE: The daily start-up procedures describe normal
operation. Assume that all temperature and pressure
settings have been previously set, but that the heating
system is not up to operating temperature.
1. Check condition isocyanate lubrication system and
service as required. Change pump lubricant when it
shows signs of change to a milky color.
2. Ensure supply fluid is at correct temperature as
recommended by chemical system supplier. Ensure
individual chemicals are correctly agitated within
their drums/day tanks, and moisture protection
system is properly set for operation. Recirculate
heated fluid back to supply drums if necessary; see
page 30.
3. Turn on main air supply to transfer pumps.
4. Pressurize transfer pumps and open A- and B-inlet
supply valves.
5. Open air inlet ball valve (DD).
6. Turn main power ON .
7. Uncoil heated hose.
8. Check that hose setpoint temperature is correct.
9. Turn on all three heat zones.
10. The hose power controller automatically adjusts the
hose current to the hose to compensate for hose
length and ambient temperature. Wait for actual
hose temperature readout to match hose setpoint
temperature.
11. Set PRESSURE RELIEF/SPRAY valves (SA, SB) to
SPRAY.
12. Check that heat zones are on and temperatures are
on target, page 22.
13. Open air motor shutoff valve.
14. Pumps will pressurize the fluid according to air
regulator pressure.
NOTICE
Uncoil heated hoses before turning on hose heater
switch to prevent overheating and hot spots within
hose.

To prevent excessive pressure build-up in heated
hoses, always bring hoses and primary heater up to
operating temperature before opening air motor
shutoff valve.
