F800e Frequently Asked Questions

Answers to frequently asked questions about the ToughTek F800e fireproofing pump.



Power Requirements

What is the impact on the sprayer with low voltage source?

The power requirement for the F800e is 200 - 240 Vac, 30 amp service, 1 phase. Running at 200 Vac versus 240 Vac will result in an approximate 20% reduction in maximum cycle rate.

Quick 220V Converter

What power does the Quick 220 converter need?

The Quick 220 power supply uses the principle that 220/240 volts AC is supplied to most facilities. The 220/240 volts is divided into 110/120 volt circuits for distribution within the building. Using 110/120 volt outlets and the Quick 220, the user can quickly identify and connect to the separate 110/120 volt halves of the original 220/240 volt, restoring the 220/240 volt AC option without adding new electrical circuits or wiring to the building.

These two 110/120 volt circuits cannot be protected by a Ground Fault Circuit Interrupter (GFCI).

Why does the Quick 220 converter, "220 Volt" not illuminate?

The Quick 220 converter needs power from two 100-120 Vac circuits that are on different phases.
Move the "PLUG B" to different outlets until "220 VOLT" lamp lights.

What is the size requirement for an extension cord that can be used with F800e sprayers using the Quick 220 converter?

Graco recommends using two 3 wire 14 AWG cord for a maximum length of 50 feet or 12AWG for a maximum length 100 feet.  Use as short a cord as possible to minimize the voltage loss to the sprayer.

Extension Cords

What is the longest extension cord that can be used with F800e sprayers?

Graco recommends using a 3 wire 10 AWG cord with a maximum length of 100 feet. Use as short a cord as possible to minimize the voltage loss to the sprayer.


Flush Mode - Reversing Motor Operation

Why did my motor reverse directions while I was flushing out fireproofing material with water?  Why does my motor sound like it is starting and stopping rapidly?

When flushing material, the system may enter "flush mode".  When the system enters flush mode, there will be a noticeable change in sound as the motor reverses directions in a back and forth motion and operates at a reduced motor current level.

The system will automatically enter flush mode on its own when flushing the hose under certain circumstances.  Typically this will occur when flushing thicker materials out of longer lengths of hose with water.  Specifically, the unit will enter flush mode if the motor drops below a minimum speed (approximately 20 pump cycles per minute) for a period of time and the pump outlet pressure is relatively high.

The system will shift back to regular operation once enough material has been pushed out of the hose and pressure has dropped.

Note that the motor rotation direction will be random after flush mode ends and that this is okay.  If the unit is stopped and started again, the motor will rotate in the default direction again.

Alternatively, the system may enter flush mode if the material is too difficult to pump through the attached hose set or if there is a blockage in a hose.  If this is the case, follow the Pressure Relief Procedure in the manual and either reduce the restriction of the hose or find and remove the blockage.


Can solvent based materials be pumped with the F800e?

No.  There are components on the F800e system that are not solvent resistant.

Are the outlet check valves required for pumping all fireproofing materials?

Graco recommends using the outlet check valves when pumping all varieties of fireproofing materials.  With the dual pump F800e design, material could backflow into the pumps if the outlet check valves are removed reducing output performance.


How often should the inlet tube assemblies on the F800e be cleaned?

The inlet tube assemblies on the F800e should be cleaned either daily or whenever material has been flushed out of the hoses with water.

Forgoing daily cleaning of the inlet tube assemblies allows material to build up within them, restricting the flow of material to the pump. This restriction causes the pump to starve and lose its prime, reducing the material output performance of the pump.
