Oasis I Series Installation & Operation Manual page 16

5.5 Adequate Water Flow
All Oasis heat pumps have a factory preset internal water flow switch. If there is insufficient water flow the
heater will not operate.
It is CRITICAL that there is sufficient water flow to the unit. Incorrect water flow can cause a loss of efficiency and
possible damage to the unit. Optimal water flow rates are listed in the Oasis manual. It is imperative that water
flow is kept as close as possible to these flow rates. Correct water flow not only offers optimal heater performance,
but may also prevent possible damage to your heater.
Before connecting the heater to the plumbing, all piping must be thoroughly flushed to ensure no debris can enter
the heater. Failure to remove pipe debris can jam or damage the flow switch and may cause damage to the heater.
When cleaning the pool it is advisable to turn off your heater as restricted water flow may cause the heater to shut
down and indicate low water flow fault (E03 error) or high pressure fault (E01 Error).
IMPORTANT: A Variable speed pump or bypass valve and plumbing MUST be fitted to allow water flow to be
adjusted through the heater. Do not direct connect a water pump with higher flow than required to the heat
pump.
5.6 Rubber Feet
All Oasis units are provided with rubber feet which we highly recommend being installed. The rubber feet help
reduce vibration of the unit and help provide a space below the heat pump to install the drainage barbs.
5.7 Condensate Drain Barb
Fit the condensate drain barb into the 2 holes under the unit if you
need to direct water away from the heater. Put in hot water if stiff.
5.8 Drainage & Condensation
Whilst the heater is operating, water in the air condenses on the fins of the evaporator. In the instance of high
humidity, the condensate may be several litres per hour. This may give the impression that the heater is leaking,
however this is a normal function of heat pumps.
The heater will automatically activate reverse cycle or de-icing mode when required which also increases condensate
discharge. This normally occurs at temperatures below 8 deg C. The condensate water will discharge through the
base of the heater. As an option a pipe can be connected to the drain on the base of the unit to direct condensate
water to an appropriate location.
NOTE: A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump running. If
the water stops running out of the basepan, it is condensation. AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER
FOR CHLORINE – if the is no chlorine present, then it's condensation.
