Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply. Note! Units
with electrical heaters can be supplied from
more than one connection.
2. The front panel/service hatch is opened by
slackening off the screws on the unit.
Maintenance
Since fan motors and other components are
maintenance free, no maintenance other
than regular cleaning is necessary. The
frequency of cleaning can vary depending on
local conditions, but undertake cleaning at
least twice a year. Inlet and exhaust grilles,
impeller and elements can be vacuum cleaned
or wiped using a dry cloth. Use a brush when
vacuuming to prevent damaging sensitive
parts. Avoid the use of strong alkaline or
acidic cleaning agents.
Overheating
The motors in all the air curtain units
have a built-in thermal safety cut-out to
protect against overheating. This will reset
automatically once the motor has cooled.
Fan replacement
1. Determine which of the fans is not
functioning.
2. Disconnect the cables to the relevant fan.
3. Remove the screws securing the fan and lift
the fan out.
4. Install the new fan in reverse order to the
above.
Changing the water coil (AGI W)
1. Turn of the units water supply.
2. Disconnect the cables to the water coil.
3. Remove the mounting screws securing the
water coil in the unit and lift the water coil
out.
4 Install the new water coil in reverse order to
the above.
Draining the water coil (AGI W)
The drain valve is on the underside of the coil
on the connector side. It can be accessed via
the service hatch.
Troubleshooting
If the fans are not working or not blowing
enough, check the following:
•
Operating power supply to the unit;
check fuses, circuit-breaker, time
switch/thermostat (if any) that starts
and stops the unit.
•
That the speed regulator is correctly
set.
•
That any position limit switch is
working.
•
That the thermal safety cut-out for the
motors has not been deployed.
•
That the intake grille/filter is not dirty.
If there is no heat, check the following:
•
Check that the settings for the
thermostat, switches etc. are set so that
the unit can produce heat.
For units with water coil, also check the
following:
•
That the water coil is bled.
•
That there is a sufficient water flow.
•
That the incoming water is sufficiently
hot.
If the error cannot be fixed, please contact a
qualified service technician.
Safety
• Keep the areas around the air intake
and exhaust grilles free from possible
obstructions!
