ZWEMBAD SERIES · AIR/WATER SYSTEM

7 HIBERNATION PROCEDURE

1. Switch off the filtering pump.
2. Turn off the by-pass valves.
3. Open completely the drain cock of the condenser (bottom left)
4. Drain the exchanger to protect it from ice.
5. Once drained part of the condenser, close the drain cock.
6. Check the connectors and the (closed) by-pass valves of the heat pump to restrict the entrance of
foreign bodies or water to the exchanger.

8 MAINTENANCE INSTRUCTIONS

This operation must be obligatorily carried out by a professionally qualified person. It should be
carried out at least once a year and includes several elements:
- Cleaning of the rear evaporator with the aid of a thin brush and a nondirty and nonchlorinated water spray.
· Revision of instructions and operating issues of the unit.
· Revision of the safety mechanisms.
· Dusting the circuit board.
· Checking the earth connections.
· Checking the gas pressure.
PREVENTIVE MAINTENANCE.
A record should be kept of each element repaired or substituted as well as of all maintenance and repairs.
The surface of the exterior panels may be cleaned with a soft cloth and non-abrasive cleaner.
DISCONNECT THE EQUIPMENT FROM THE POWER SUPPLY before performing any maintenance
procedures.
To keep in mind:
EVAPORATOR COIL:
The evaporator coil should be kept clean and free of obstacles which may hinder the circulation of air through
them. In order to clean it, use water (little pressure) and non-abrasive detergents or cleaning liquids made
specifically for it.
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:
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 (0º C).
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.
