GENERAL INFORMATION

CAUTION: Operating the unit without liquid for more than 5 seconds can result in damage
to the pump. Evidence of dry operation will void the warranty. Read the installation and
start-up sections before operating.

DESCRIPTION

The Remcor Model CFF Liquid Circulator is a self–contained unit consisting of a pump, heater, cooling system,
and 2–stage thermostat housed in a rugged cabinet with a baked-on finished. It will operate with any water
system up to a maximum of 30 gallons (113 liters). The CFF is not designed for continuous cooling at water
temperatures above 85°F (29°C), although short term operation at higher temperatures with no external heat
load is acceptable for pulling down the system temperature.

INSTALLATION

FRONT PANEL REMOVAL

In order to make connections to the CFF, it will be necessary to remove the front panel by removing the
fasteners on the front of the unit and then sliding the panel forward. When replacing the panel, slide it straight
back until it is engaged under the rear retaining flange, and replace the front fasteners.

Location

The CFF must be located such that the pump inlet is below the normal operating level of the bath to which it is
connected. Failure to do so will cause improper operation and damage to the pump.

The following clearances must be maintained around the unit for proper operation

Top – open
Right Side – 24” (152.4mm)
Left Side – 12”

Liquid Connections

Figure 2 (page 3) shows proper and improper methods of making liquid connections.. Liquid tubing should b
5/8” I.D., and hose clamps should be used to insure a tight connection.

The inlet hose should run through the hole in the rear panel and connect to the pump suction connection. This
line must run from a drain at the lowest point in the bath, and should not contain any inverted traps which could
cause air binding and loss of prime. In open systems where foreign material may be present the bath drain
should be raised slightly and fitted with a screen to prevent the entrance of such material into the inlet hose.

The outlet hose connects to the top of the CFF tank, and may enter the bath at any convenient point. Care
should be taken in larger systems to prevent “short circuiting” of liquid between inlet and outlet connections
which are to close together in the bath, as this will cause wide temperature variations. If and air trap must be
present in the outlet line, then it should be provided with a vent valve to allow the complete removal of air.

In closed systems (where the system is not open to the atmosphere), the installation should include a “surge
pot” located at the highest point in the outlet line, to facilitate proper purging of air and to allow for expansion
and contraction of the liquid in the system with changes in temperature. This pot should normally have
approximately 1/10th the total volume of the system, and a small air space must remain at the top for proper
operation.
