WARNING
PRESSURIZED FLUID HAZARD AND
MOVING PARTS HAZARD
The bleed-type master air valve (C) and
auto depressurization valve (P) are re-
quired in your system to relieve air
trapped between this valve and the
pump after the pump air regulator is
closed. Trapped air can cause the pump
to cycle unexpectedly, which could result in serious
bodily injury, including splashing in the eyes or on
the skin and injury from moving parts.
4-Regulator Air Control Module (shown)
For more information, refer to Fig. 2 on page 8. The
following components are included with the module:
Bleed-type Master Air Valve (A) is used to shut off
the air supply from the entire supply unit.
Bleed-type Motor Air Valve (214) is supplied in your
system to relieve air trapped between it and the air
motor when the valve is closed (see
WARNING
above). This bleed valve should be easily accessi-
ble and located downstream from the air regulator.
It can be used as a safety lockout.
Pump Air Regulator (204) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. It is located on the air control panel up-
stream from the bleed-type master air valve.
Auto Depressurization Valve (106) exhausts air
from the system at shutoff. The built-in control
delays startup to allow material to heat thoroughly.
Ram Air Regulator (224) controls the air pressure
to the ram. There are separate air regulators to
control the ram pressure in the up and down direc-
tions.
Ram Air Supply Hose connects the ram air regula-
tor to the air manifold.
Ram Plate Blow-off Valve controls the air pressure
to the ram plate blow-off.
FRL (filter, regulator, lubricator) (202), (203), and
(204) conditions the air to the ram and the pump.
The pump air regulator is located in this assembly.
The ram air is taken from this assembly; an air line
tube connects the FRL and the ram air control
module.
Fluid Line Accessories (Typical)
A pressure compensator valve controls fluid pressure
to the gun/valve, and dampens pressure surges. Install
the pressure compensator valve in the position shown
in the Typical Installation, using adapters as neces-
sary.
Vent Hood Kit (if supplied)
The vent hood assembly is designed to efficiently draw
fumes to the factory exhaust system during drum
change-out. This assembly requires connection to a
factory ventilation system that draws a minimum air
flow of 8.4 m
3
/min (300 scfm). This kit is recom-
mended for Polyurethane Reactive (PUR) applications.
Heat Control Zone Selection
The Therm–O–Flow Plus can be ordered with six
(Code E–1) or eight (Code E–2) heat zones. Zones 1
and 2 are always used for the drum heated platen and
the heat pump. Zones 3 and 4, 5 and 6, and optional
zones 7 and 8, are available as paired zones through a
16 pin connector. The heated hoses have a 16–pin
connector on the inlet end cable, and an 8–pin connec-
tor on on the outlet end cable. All heated valves,
manifolds and heaters are equipped with an 8–pin
matching connector. Accessory cables are available
for other possible connections.
