Installation

General Information

NOTE: Reference numbers and letters in parentheses

in the text refer to the callouts in the figures and the parts drawing.

Prepare the Operator

All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.

Prepare the Site

Ensure that the wall is strong enough to support the weight of the heater and accessories, fluid, hoses, and stress caused during operation.

Keep the site clear of any obstacles or debris that could interfere with the operator’s movement.

WARNING

COMPONENT RUPTURE HAZARD

Heat causes fluid to expand. If the heated fluid is trapped with nowhere to

expand, it can cause component rupture. Be sure to keep the heated fluid circulating (turn the 3-way recirculation valve to the circulation position). Do not install a fluid shutoff device between the heater and the gun.

To convert a pump module to a heated package, install the heater module as follows.

NOTE: Refer to Fig. 1, and to the Mounting Hole Layout on page 11.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 7.

Installing the Heater Module

WARNING

FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD

The Viscon HP Heater must be installed by a qualified electrician in compliance with all state and local codes and regulations, to reduce the risk of electric shock or other serious injury during installation or operation.

When installing in a flammable atmo-

sphere (hazardous location) refer to Article 500 of the US National Electric Code or other applicable agency standards to plan the work.

Refer to the Technical Data and to the supplied Viscon HP Heater manual for information on heater power supply requirements.

Do not plug in or unplug a power cord in any area containing flammable fluids or fumes, to avoid fire or explosion resulting in serious injury.

Do not put all flammable materials and debris on or near the heater. Keep the work area clean.

1. Relieve the pressure.

2. Unscrew the swivel (A) from the nipple (B). Remove the fluid filter (C) and connected parts. Remove the nipple (B) and ball valve (F) from the filter and discard them. See the Disassembly Detail in Fig. 1.

3. Position the heater bracket (5) to the right of the pump bracket (D), at the same height. The two slots must face up. The center of the two outer left holes must be no more than 9 in. (228 mm) from the right edge of the pump bracket. See page 11.

4. Check that the heater bracket (5) is level. Using the bracket as a template, mark the four outer holes on the wall. Refer to the Mounting Hole Layout on page 11. The four outer holes are used to mount the bracket to the wall, and the two inner slots and two inner holes are to mount the heater (1) to the bracket.

5. Drill four holes in the wall.

6. Bolt the bracket (5) to the wall with 1/2 in. bolts and washers. Use bolts that are long enough to keep the bracket from vibrating during operation.

7. Install two screws (E, included with the heater) into the top two heater mounting posts until they are about 1/8 in. (3 mm) from fully installed.
