CFH-4000 IN-LINE RESIN HEATER MANUAL
INTRODUCTION
The MVP Clean Flow Heater (CFH) is designed to allow higher flow rates, give better
control over temperature change and boasts a new easy maintenance design.
The CFH-4000 Heater is heated with a single 3000 watt cartridge type heating
element, requiring 240 Volt, single phase electrical service at 15 amps. Material
temperature is indicated on the thermometer on the outlet side of the heater.
The rheostat circuit consists of a bimetal timer that can be adjusted from 0 to 100% of
the heater’s wattage. The rheostat circuit is wired through a thermal limiter. This is a
safety feature that breaks the circuit to the heating element if heater block
temperature exceeds a safe level. In addition, all heaters contain 15 amp fuses in the
electrical enclosure for protection.
There are two models of the CFH-4000 in-line resin heater:
CFH-4000-B Basic Clean Flow Heater – In-Line Resin Heater
CFH-4000-AI Clean Flow Heater – In-Line Resin Heater – Air Interlock
The CFH-4000-B Basic Clean Flow Heater is the base model of the CFH heater with
a single temperature adjustment knob which allows for simple operation. Just adjust
the temperature control to the desired level to maintain the desired temperature
indicated on the thermometer.
The CFH-4000-AI Clean Flow Heater – Air Interlock is unique in that it is an on
demand type heater and uses electrical power only when there is flow. The heater is
controlled by triggering the gun, the system regulator supplies pressure to the gun
valve which in turn activates the heater when the trigger is pulled. Once material is
flowing, an air signal is supplied to heater which engages the thermostat circuit.
When controlled with the air/electrical interlock heater switch, The CFH heaters
require a minimum of 15 psi air. The heat element is supplied with current from two
separate air circuits: the preheat circuit and gun trigger circuit. A preheat circuit is
operated to manually warm the heater block to desired operating temperature before
start-up.

OPERATION
To operate the CFH heater, just set the temperature control to mid-position or to the
desired position if the setting is known.
Heater is now ready.
To preheat the CFH-4000-AI (system with air interlock) press the preheat button and
hold until heater block feels warm to the touch. This insures resin is heated from
start-up to stop. If this system sets idle for a long period of time it may need to be
preheated again before use.
Using heat with polyester resin systems allows control of the spray pattern through
reduced viscosity while breaking up material particles, thereby giving better, more
desirable wetting characteristics. As it is highly accurate, material can be controlled
within plus or minus 3° F in continuous use.
If the spray pattern is too coarse and narrow, set heat higher, If too fine and thin, set
heat lower. Once resin in hose has been replaced by resin in heater, it will be
possible to determine if block heat has been set properly. The thermometer on outlet
side will also determine what temperature it is operating at. DO NOT EXCEED 135° F
OUTLET TEMPERATURE.
(Proper setting will vary with ambient room temperatures, flow rates and
characteristics of each resin or gel coat)
When highly promoted resins are used, it is advisable to pump cool resin through
heater after power has been removed from the heater. These resins could easily gel
if left at high temperature in block for an extended period. Anticipate your cut-off and
you will be able to use it all. Use preheat button again before starting.
When used on automatic heads, the heater should be connected to automatic gun
trigger circuit; if preheat transfer pump, connect to pump control.

MAINTENANCE
(Refer to Parts Drawings)
1. Periodically, the heater should be flushed out by pumping solvent through,
2. Inspect electrical cord for wear or damage and repair or replace as necessary.
3. Inspect hoses attached to the heater for wear of damage and replace
4. Check heater and hoses for leaks and replace periodically.
ALWAYS DISCONNECT POWER AND NEVER FLUSH WITH SOLVENT UNTIL
HEATER HAS COOLED TO ROOM TEMPERATURE. PRESSURE NOT TO
EXCEED 2500 PSI
especially with gel coat or filled resin systems.
periodically.

TROUBLESHOOTING INSTRUCTIONS
Two basic problems may occur with the MVP Resin Heater:
Loss of electrical current or heat
Material flow blockage or leakage.
Loss of Electrical Current or Heat:
1. Indicator Light: If indicator light is not sequencing during operation, try preheat
button to see if light comes on. If not, inspect bulb and replace if defective. Also,
check diodes for continuity. If light does not operate and no heat is generated in the
heater and diodes are OK, then
DISCONNECT POWER FROM THE UNIT.
2. Fuses: Remove lid to electrical enclosure and check all fuses to insure they have
not blown out. If so, replace.
3. Loose Wire: Check all connections for loose or disconnected terminals.
4. Rheostat: NOTE: Air must be ON for rheostat check. If rheostat controlled function
is not working, disconnect wires and check continuity through rheostat when it is cool.
If there is continuity-check that it’s getting current from normally open contacts of
microswitch. If no continuity through rheostat, it is faulty and must be replaced. If
neither preheat or thermostat function works, check fuses first, then make sure pilot
light is not burned out (remove bulb and inspect).
5. Thermal Limiter: Once fuses and rest of circuit has checked out, disconnect wires
and check continuity through thermal limiter when it is cool. If there is no continuity
through switch when cool (room temp. 70° F) it is faulty and must be replaced.
Heat limiter may be adjusted to trip at different levels and may need readjustment.
MVP factory setting is to trip at approx. 120° F.

6. Heating Element: If all components to this point check out, heating element is
faulty. Heater element should be checked for leakage to ground and continuity
through element.
CFH-4000-AI Air Interlock units:
7. Air Switch: Disconnect wires and check microswitch to ensure continuity through
normally closed contacts when air supply is off.
If there is no continuity, inspect air actuator to insure it is disengaging. If air actuator
disengages properly, switch is faulty and must be replaced. Next apply air pressure
(at least 30 psi) to air actuator.
Check continuity through normally open contacts. If none, check actuator to insure it
is engaging switch. If not, a small amount of oil may free actuating cylinder or it may
be adjusted if not engaging far enough. If actuator is engaging switch properly but
there is no continuity through normally open contacts, switch is faulty and must be
replaced.
8. Preheat Air Valve / Button: Check that the air valve has a constant air supply,
20psi minimum. Disconnect the outlet air line and make sure that an air signal is sent
when the button is pushed. If no signal air is sent when the button is pushed, check
the valve for blockages and replace as necessary.
Material Flow Blockage and Leakage Problems:
1. If heater is completely blocked, the end caps should be removed and resin
passages thoroughly cleaned. Make sure the passages in the end caps are clean as
well. Fittings into and out of heater should also be cleaned.
2. In case of leakage, check that perimeter end cap bolts are correctly tightened at 60
ft/lb. If so, remove end caps and inspect O-rings, Clean O-ring groove thoroughly.
