COMPRESSOR COMPRESSOR COMPRESSOR COMPRESSOR
Compressor oil must be checked in those unit models provided with an oil viewer.
Verify that the compressor refrigerates adequately with the circulating gas (verify the

refrigerant charge).

Verify that the power consumption has not increased.
Verify that the compressor discharge pressure is not too high and that the intake pressure is not
too low.
Verify that the compressor fasteners are not deteriorated.
Verify that no frost develops on the compressor.
CONDENSER CONDENSER CONDENSER CONDENSER
Install chemical feeders "downstream" from the heat pump, as far away and at a lower height.
The feeder should never be installed near the intake of the purification pump as this will
damage the condenser.
NEVER introduce concentrated chemical products in the pool skimmers as this will damage the
Titanium condenser.
In climates where temperatures occasionally fall below freezing, circulate the water using the
purification pump to maintain the water temperature above freezing (32º F).
In the case these temperatures are persistent or habitual, the heating and purification system
should be completely drained. The condenser has a lateral plug the purge the system.
FAN FAN FAN FAN
Verify the flows of the fan each year.
Clean the louvers of the fan as well as the protection grill regularly.
ELECTRICAL PANEL ELECTRICAL PANEL ELECTRICAL PANEL ELECTRICAL PANEL
Verify all electrical connections.
Verify that there is no over-heating of the electrical terminals.
Verify that the protection systems operate correctly.
Verify that the regulator operates correctly and verify the temperature with a mercury
thermometer (calibration probe).

heating and air conditioning units.
DRAINING THE COOLING CIRCUIT DRAINING THE COOLING CIRCUIT DRAINING THE COOLING CIRCUIT DRAINING THE COOLING CIRCUIT
It is imperative to drain the cooling circuit before charging the refrigerant.
First draining procedure:
Connect the gauge tubes to the intake pressure lines of the circuit (low pressure) and to
•
the return pressure lines (high pressure).
Connect the main line of the gauge to the vacuum pump.
•
Open all the valves, including the solenoid and the regulating valves.
•
Open the valves of the gauge (LO = low pressure valve / HI = high pressure valve).
•
Activate the vacuum pump and wait until the circuit is completely drained.
•
Close all valves or stopcocks and disconnect the vacuum pump.
•

The equipment uses R-407C class refrigerant.
This is the reason why the gas taken from the refrigerant bottle must be introduced in the low-
pressure circuit by means of a charger (expansion system).
