GENERAL

WARNING: This heater is not intended for use in haz- ardous atmospheres where flammable vapors, gases, liquids or other combustible atmospheres are present as defined in the National Electrical Code. Failure to comply can result in explosion or fire.

The CVCHS is a clean solution or corrosive solution circulation heater ideally suited for sidearm heating, in-line circulation and engine preheaters.

The INCOLOY® sheathed tubular heating element is centered in a CPVC pipe body. This material is a good thermal insulator in reducing heat loss and eliminating the need for support jackets. Its screwplug type mounting provides easy removal when necessary.

The CVCHS has a stainless steel flange.

An integral 60° — 180°F range thermostat is provided to control outlet temperatures. However, this control does not fail-safe. Therefore automatic reset (195°F) cutout is provided.

WARNING: Users should install adequate back-up controls and safety devices with their electric heat- ing equipment. Where the consequences of failure may be severe, back-up controls are essential. Although the safety of the installation is the respon- sibility of the user, Chromalox will be glad to make equipment recommendations.

INSTALLATION

WARNING: Hazard of Shock. Disconnect all power before installing heater.

1.When the CVCHS Circulation Heater is vertically mounted, the terminal housing will be at the top of the heater.

2.When mounting the heater horizontally, the outlet pipe must be up. This is to prevent any inadvertent drainage of the heater.

3.No additional support other than the connecting pipes is needed.

4.Make piping connections to either new or existing plumbing at the 1” x 111/2” N.P.T. threaded inlet and outlet as shown in Figure 1.

5.DANGER: Hazard of Fire. Provide minimum of 6” spacing from chamber and related piping to nearest combustible materi- al. Avoid operation of heater near combustible fluids or in com- bustible vapor or gas laden atmosphere.

6.Provide adequate space at terminal end to permit withdrawal of the heater from chamber should servicing be required.

WIRING

WARNING: Hazard of Shock. Any installation involv- ing electric heaters must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.

1.Be sure line voltage matches heater voltage (on nameplate).

2.Electric wiring to heater must be installed in accordance with local and National Electrical Codes by a qualified person as defined in the NEC.

3.Remove terminal cover by backing out screw in center of cover and feed wires through the conduit bracket.

4.Connect one wire to the pigtail lead and one to the unused ther-

mostat terminal. Note: Do not disturb the existing jumper wire.

5.To set thermostat, turn the slotted screw at top of thermostat counter-clockwise until flat side is facing terminals. This is the “OFF” position.

Next, turn the slotted screw clockwise until slot in screw points to the desired temperature shown on scale. Note: Scale is marked in increments of 60°F. Replace terminal cover. (See Figure 3)
