3.8 Starting up for the first time
After all the connections have been made and checked, the following
steps must be taken:
1. Turn on the filter pump. Check for leaks and make certain that the
water flows from and to the swimming pool.
2. Connect the current to the heat pump and set the switch to ON. The
appliance will start up after the time delay (see below) has elapsed.
3. After a few minutes check whether the air being expelled from the
appliance is cooler.
4. Leave the appliance and filter pump in operation 24 hours per day
until the desired water temperature has been reached. At this point
the heat pump ceases operation. The appliance will now start up
again automatically (as long as the filter pump is in operation)
whenever the swimming pool temperature falls to 1 degree below
the programmed temperature.
Depending on the initial temperature of the swimming pool water and the
air temperature, several days may be needed to bring the water up to
the temperature required. Covering the swimming pool properly can
considerably shorten this period.
Time Delay – the appliance is fitted with built-in start-up delay of 3
minutes as protection for the electronics and to increase the life of the
contacts. After this interval, the appliance will restart automatically. Even
a brief interruption in the flow of current will activate this delay and thus
prevent the appliance from starting up immediately. Additional
interruptions in the current during this delay will have no influence on the
3-minute countdown.
3.9 Condensation
The intake air is cooled significantly as a result of the operation of the
heat pump when heating the swimming pool water, and water may
condense on the fins of the evaporator. When humidity is high, this could
even amount to several litres per hour. This is sometimes erroneously
seen as a water leak.
