Never push the equipment beyond its design limits.

If it will not do what you want with reasonable ease and
speed, assume you have the wrong heater for the job.
Contact your local HSS Hire Shop for advice.

Keep the equipment clean

- you will find this less of a

chore if you clean it regularly, rather than wait until the end
of the hire period. 
When not in use

, store the equipment somewhere

clean, dry and safe 

from thieves. 

Set the switch to ‘fan only and wait for the unit to
cool down. 
Once cool switch the supply OFF and unplug it from
the power supply.
All that remains is to give the unit a final clean up
ready for return, 

to your local HSS Hire Shop.

EQUIPMENT CARE

FINISHING OFF

The heater has a three position switch, ‘0’ for fan
only, ‘1’ for 9Kw heat output, and ‘2’ for 18Kw heat
output.

Note that

when the unit is connected to a power

supply and the supply is switched ON, the fan will
run in all three switch positions. 

Only when set to No

1 or 2 will heat be emitted
Having double-checked that the heater switch is set to the
‘0’ (fan only position),

plug the heater into its power

supply and switch the supply ON.  

Model 1…
Start by setting the switch to position ‘1’, 

this will

activate the fan without heat.

Check that the fan is

running BEFORE you move the switch to position ‘2’

(the 6.5Kw heat setting). 

If the fan fails to run, 

DISCONNECT THE UNIT AND

SWITCH THE SUPPLY OFF then 

contact your local HSS

Hire Shop for advice. 
Once 

you have confirmed that

the fan is running move

the switch to position ‘2’, 

this will give an output of

6.5Kw and may prove to be sufficient for your needs.

If 

setting ‘2’ proves

insufficient, move the switch to

position ‘3’.

Always

avoid using more heat than is required 

and

keep an eye on the room temperature as the heat builds
up.
When you want

to switch the unit OFF, turn the

switch to position ‘1’ and leave the unit for at least 5
minutes. 

In this position,

only the fan will run and 

will

help

cool down the heating element 

before you handle

the unit.

The ‘fan only’ setting can be used 

if you wish

to

circulate air without heating it.
Model 2…
Check that the fan is running BEFORE you move the
switch to position ‘1’ 

(the 9Kw heat setting). 

If the fan fails to run, 

DISCONNECT THE UNIT AND

SWITCH THE SUPPLY OFF then 

contact your local HSS

Hire Shop for advice. 
Once 

you have confirmed that

the fan is running move

the switch to position ‘1’, 

this will give an output of 9Kw

and may prove to be sufficient for your needs.
