Vertical Delivery, Operation and Maintenance

Installation Instructions

Vertical Delivery

In buildings with high ceilings or bays, vertical delivery unit heaters are recommended to produce comfort in central areas. They are best used when the perimeter heat loss is adequately controlled. In combination with horizontally discharged units, they aid in providing good air mixture (See Figure 4).

Vertical discharging units are mounted high above machinery, assembly lines, etc.

In an application where only vertical discharging units will be used, the air streams must overlap to blanket outside walls and provide good heat distri- bution (See Figure 5).

General Safety Information

The ceiling or wall on which the heater is to be mounted must be of adequate strength to support the heater. Plaster or suspended ceilings will not support this type of heater. For greater stability, we recommend the use of threaded rods.

Do not mount the heater where volatile liquids or gases will be present or where it will be exposed to rain or mist. All combustible materials should be kept at least 3 feet away from front of the heater.

In an area where the air temperature will be main- tained at less than 68˚F, the heater should be mount- ed in a position that will not blow directly on people working in the area.

A minimum clearance for each heater (both hori- zontal and vertical mount) is listed in Figure 6. Please follow these recommendations when mounting to avoid potential problems with the func- tion and safety of the heater.

Mounting the CEH Unit Heater

CAUTION: THE CEILING OR WALL MOUNTING STRUCTURE AND ANCHORING PROVISIONS MUST BE OF SUFFICIENT STRENGTH TO SUPPORT THE COMBINED WEIGHT OF THE HEATER AND MOUNTING BRACKETS

Vertical Discharge

(See Figure 6 for minimum clearances)

1.Install four 5/16-18 threaded rods into the threaded holes in the back of the heater and secure in place using lock (jam) nuts (Figure 7).

2.Attach the four mounting rods to ceiling or over- head structure and anchor securely.

NOTE: When mounting for vertical discharge, position unit so that access door opens away from nearest wall. This permits maximum access to wiring compartment (Figures 2 & 6).

Operation and Maintenance

How to operate your heater

Turn your built-in or wall thermostat to the desired setting. The heater will run for approximately twenty seconds before the fan comes on. The heater will then run until the thermostat setting is reached. Fan will continue to run with elements shut off for approximately seventy seconds and then will shut off. This cycle will continue as need- ed based on thermostat setting. Do not use break- er panel or fuse box to control heater. Be sure power to heater is constant all the time.

Maintenance

1.Shut off circuit breaker to heater.

2.Remove front diffuser grill or 3 of the center louvers in front of fan area.

3.Using a compressor, blow air through the outer cabinet louvers and finned element areas.

(Do not touch sharp surfaces on elements). While holding fan blade (to avoid damage or bending) carefully blow inside the fan motor area.

4.Carefully wipe off the fan blade without damaging or bending it.

5.Reinstall front diffuser or air vanes.

6.Restore power to heater.

WARNING! Risk of Electrical Shock. Turn off all power at the electri- cal panel board sup- plying power to the heater before doing any electrical wiring.

WARNING! Overheating or fire may occur. DO NOT place the heater behind doors.
