The water pressure switch senses when the
circulating pump is running and ensures there
is water flow before the Heat Pump starts. It
is factory set to start the Heat Pump when the
water pressure reaches 35 kPa and stops it
when it falls below 20 kPa. The water
pressure switch (which is located close to
where the refrigerant pipes enter the heat
exchanger), is adjustable.
If the pressure is too low to activate the water
pressure switch (AMBER light glows),
proceed as follows :-
1. Check filter condition and clean or
backwash if required.
2. Check for blocked lint pot or skimmer box.
3. Disconnect any pool accessories, such as
pool vacuums, that may be hindering
flow.
4. With the Heat Pump switched off, lower
the pressure switch setting and listen for
a distinct 'click' as the circulating pump
starts and stops.
5. If the Heat Pump is located lower than the
water level of the pool, the 'head' of pool
water may be sufficient to hold the water
pressure switch in the ON position.
Adjust the water pressure switch setting
to avoid this happening.
6. If the water flow into the pool is
unrestricted (open pipe or without jets), a
restrictor or tamper-proof valve needs to
be installed to increase the water
pressure to around 50 kPa.

The controller displays the temperature of the
water entering the Heat Pump. Adjust the
thermostat to approximately 28
o
C. Press
'SEL' to display the current setpoint then
adjust with the up and down arrows. Press
'SEL' again to set the desired temperature.

Both the red and amber lights must be on
before the Heat Pump will start. Each light
indicates the following :-
•
RED - glows when the Heat Pumps'
control switch has been turned on and
there is power to the unit.
•
AMBER - glows when the circulating
pump is running and the water pressure
switch has closed. (I.e. there is sufficient
water flowing).

The Heat Pump has other safety devices
which may prevent the unit from operating
while a non-critical fault exists. These are the
refrigerant high pressure and low pressure
cut-out switches.
If both the red and amber lights are on, and
the Heat Pump fails to start, switch off the
control switch and the power supply, then
turn both back on. This should re-set both
high and low pressure switches. The Heat
Pump should start again.
If after a brief period of 2 to 15 minutes, it
stops again, check that there is sufficient
water flow and that there are no blockages in
the pipes.
If the water flow is high, check the unit again
after 10 minutes.
If the unit stops again, turn off the power and
call your Carrier representative or the
company you purchased the Heat Pump
from.

HLORINATORS
Excessive chlorine in the pool water,
compounded by variable heating and filtration
cycles, may increase corrosion in the heat
exchanger material. Monitor the chlorine
levels in the pool regularly (daily is
recommended) to keep it within safe limits.
Also, maintain the pool within the water
temperatures recommended in the Owner's
Manual.
