MAINTENANCE
E. CONDENSATE DRAIN TUBE
The unit is equipped with two condensate water drains – a primary drain and an overflow drain. A monthly check is
recommended to ensure that these drains are not blocked. Blockage at the primary condensate water will trigger an
alarm and shut the heat pump off.
IMPORTANT
If the primary condensate drain is clogged the unit will sound an alarm and display error code A8. The unit will also
switch from Auto or Econ mode to Heater mode until the condensate block is cleared. The unit will run an auto check
every 48 hours (default – can be changed by accessing parameter F89 in the control panel) for condensate clearance.
If the condensate has cleared, the unit will revert to Auto mode. Else, the unit will continue to operate in Heater
mode.
F. EXTENDED SHUTDOWN
If you will not be using the unit for an extended period of time, shut off the power and water supply to the unit. It is
recommended that the unit and water piping be drained completely. Drainage is necessary if the unit is exposed to
freezing temperatures. Ensure that the controls are checked by qualified personnel and the unit is completely filled
with water before restarting the unit after an extended shutdown.
G. MAINTENANCE SCHEDULE
AirGenerate™ recommends the unit be inspected annually by qualified service personnel to check electrical wiring,
controls and heating elements.
