14.MAINTENANCE
Before any maintenance or cleaning of the unit make sure the switch is off and no power to it
This section is intended for end users and is very important to maintain regular operation of the unit over time. A few operations,
carried out regularly can prevent serious intervention by the staff.
Necessary operations do not require particular expertise and are summarized in simple controls of some components of the unit
.
-
Clean outdoor coil, the skin must be able to get through maximum heat exchange. Therefore, it is always necessary to keep
its surface free of dust and dirt that could be deposited by the action of the fans..
•
With a brush to remove all foreign objects such as paper, leaves, etc, who are on the surface of the outdoor coil..
•
Clean the aluminum surface of the outdoor unit, eg a vacuum cleaner
•
Check that all fins are not damaged or bent.
-
Control water flow defrost: During winter operation, occurs from time to time the defrosting of the outdoor coil. You need to
check that the drain is not blocked. If drainage is not correct, with cold temperatures, it could form a layer of ice on the base, which
would compromise the functioning of the whole system
.
We recommend a regular maintenance by qualified personnel
Here are some checks to be performed:
•
Check direction of rotation of the DHW pump, and the possible presence of air on the pump.
•
Check that the pressure of condensation and evaporation in this mode are accurate at all times, depending on the
temperature of DHW and outdoor air temperature.
•
Check the power consumption (Amps) of the unit operating conditions at that time.
•
Check that the unit in this mode to achieve the temperature selection.
•
Check that when the temperature drops to DHW temperature selection, the unit starts to operate in this mode.
•
Check direction of rotation of the pump air conditioning, as well as the possible existence of air in the system.
•
Check that the pressure of condensation and evaporation in this mode are accurate at all times, depending on the
temperature of cooling water flow and outside air temperature.
•
Check the temperature drop in cooling water, is within the recommended range. If not, check: water pump, air in the
water circuit, dirt in the water system, etc) .
•
Check the power consumption (Amps) of the unit operating conditions at that time.
•
Check that the unit in this mode to achieve the temperature selection.
•
Check that when the temperature drops to air conditioning temperature selection, the unit starts to operate in this
mode.
•
Check and clean air conditioning water filter
•
Check and clean tap water inlet water filter
