Cleaning the Heat Exchanger
•
Isolate the unit from the electrical supply
• Remove the front housing as shown on Page 7. ( Do not remove the electrical connection cover.)
• Referring to the drawings on Page 15, remove the "T" shaped screw handle stored within the main body of
the fan. Screw the handle gently into the centre hole of the heat exchanger plage (Fig 1) and carefully extract
the whole exchanger (Fig 2).
• Remove the filter mesh from the external end of the exchange (Fig 3) and clean off any accumulated dust.
Replace carefully.
• If there is any accumulation of dust on the black plastic tubes, remove this with a soft brush. Take care not
to damage the tubes.
• Re-insert the heat exchanger fully into the housing, remove the extraction handle and return it to its storage
position (Fig 4).
• Replace the outer section (Fig 5).
• Reconnect the electrical supply.
Models available
The Heatrec1003 has been designed for continuous operation at a choice of two trickle speeds. The speed can
be boosted to maximum by means of the pull cord or a remote switch, or automatically by the integral humidis-
tat.
HREC1003 - 3 speed, continuous running with a pull cord. Speed can be boosted to maximum by means of the
pull cord or a remote switch. Pulling the cord again or switching off will revert the speed of the fan to the trickle
speed.
HREC1003t - 3 speed, continuous running fan with timer and pull cord. The timer version will run at low speed
until the boost speed is activated by means of the cord or, if the cord is removed, by means of a remote switch,
light switch, PIR sensor or humidistat. If the boost speed is activated, the fan will operate at high speed until the
boost switch is turned off. After this, the fan will continue at high speed for the length of time set on the timer
overrun adjustment, between 0 and 30 minutes. After the overrun time has elapsed, the fan will return to the
slower speed.
HREC1003Ht - 3 speed, continuous running fan. The fan runs continuously at the pre-selected lower speed,
and the boost (speed 2) will start to operate automatically when the relative humidity (adjustable between 40%
and 90% +/-5% tolerance) reaches the pre-set level and will continue to operate at this speed until the humidity
has been dispersed and the adjustable over-run timer (adjustable from 0 to 30 minutes) has completed its
cycle. The boost speed can also be activated by as described for model HREC1003T.
Summer By-pass Function - The Heatrec1003 is fitted with sensors which monitor the air taken and extracted,
ensuring optimal comfort and energy saving in all seasons.
- When the outside temperature is comfortable and the inside ambient temperature is lower than 18ºC, the
air extract motor will be automatically switched off, whilst the air intake motor will continue to operate,
ensuring a quick and efficient change of air inside the room.
- When the outside temperature is higher than 26ºC, to continue to ensure room ventilation without affecting
comfort by increasing the temperature, the air intake motor will be switched off.
Frost-Stat Function - the unit is fitted with an internal thermostat, which will automatically disable the air intake
if there is a risk of the heat exchanger freezing up (when the outside temperature is too low) and also avoiding
the intake of very cold air.
