THERMOSTATS

1- For best results, do not exceed mounting heights as per

table below :

Maximum recommended mounting height :

2 - 10 kW 2.4 m (8 ft)

15 - 30 kW 3.0 m (10 ft)

40 - 60 kW 4.5 m (15 ft)

2- Direct discharge air streams :

- Away from room occupants.

- Away from columns, posts, machinery and partitions.

- Parallel to outside walls.

- Along the windward side of buildings exposed

to prevailing winds.

3- Locate thermostats on interior partitions, walls or posts

(insulate from cold steel posts). Install thermostats away

from cold drafts, internal heat sources and from heater

discharge.

4- Small rooms require only one unit heater. In large rooms,

arrange multiple units to provide perimeter circulation as

illustrated in ﬁ g. 1 and 2.

POWER SUPPLY CONNECTIONS

The power supply may be single or three phase as shown on

the nameplate. The wiring diagram is on the inside of the

terminal compartment cover. Wire heater in accordance with

local and national codes.

TEST

- To test the unit heater, temporarily set thermostat to

maximum temperature.

- Make sure that the fan rotates in the correct direction;

airﬂ ow should be in the direction of the arrow such as

indicated on the ﬁ g. 4.

WARNING

- Disconnect all power supplies before working on circuit.

- Do not heat air containing combustible materials.

- Mount heater out of reach.

- Install at least 61 cm (2 ft) from ﬂ oor

except 40 - 60 kW at least 2.4 m (8 ft) from ﬂ oor.

Minimum clearance from walls and ceiling are :

2 - 10 kW 10 cm (4 in.)

15 - 30 kW 15 cm (6 in.)

40 - 60 kW 30 cm (12 in.)

OVERTEMPERATURE PROTECTION

The motor and the electric heating elements are protected

against overtemperature by automatic reset thermal

high-limits.

Cycling of either high-limit is an indication of abnormal ope-

ration and should be corrected at once.

LUBRIFICATION OF MOTOR

The motor includes sealed lubriﬁ cation-free bearings.

MAINTENANCE

Once a year, remove the dust accumulation inside the heater

using a vacuum cleaner or compressed air. Cleaning should be

done while the heater is disconnected from the supply circuit.

A qualiﬁ ed technician should perform any other servicing.
