Setting Up Your Ultratemp-E; Water Flow Setting - Pentair UltraTemp-E Serie Guide De L'installateur

Setting up your ultratemp-E

Installation
After having connected the heat pump to the pool water circuit system trough a suitable by-pass and having made the
electrical connections by a qualified engineer, please verify the following points:
 Appliance is in a horizontal position and on a solid ground.
 Water circuit is primed (full of water): no air inside the
tubes or the heat pump tank.
 Water circuit is well connected (no leaks and no chance of
injury due to badly fitted hydraulic couplings).
 Electrical circuit is well connected (all cables tightened
correctly at terminals and intermediate circuit breaker),
insulated and earthed correctly.
 The installation requirements described previously are
strictly adhered to.
 Ambient temperature is between :+ 3 and + 35°C
 Water temperature is between 15 and 30°C
You can then start up your machine. Follow the instructions
below in the given order each time you start up the pool heat
pump, especially at the beginning of the swim season:
 Open the three by-pass valves and then half close the
settings valve
 Start the pool pump
 Turn on the pool heat pump with the on/off switch .
 Check the machine to make sure that it starts only together with the filtration pump: If the filtration pump is not
working, the "flow" LED will stop lighting. If it doesn't detect any water flow, please see chapter an alarm will be
generated
 The pool heat pump will work after a delay of few minutes.
 Set the temperature using the up or down arrow.
 After a few minutes (time for circuit to heat itself) you can regulate water flow as explained hereafter (Chapter

"Water flow setting")

Water flow setting
To optimize the performance of the heating process, it is advisable to regulate the water flow through the heat pump.
The adjustment must be carried out according to the indication given by the pressure gauge. The setting is modified
by opening or closing the setting valve of the by-pass.
To increase the pressure on the manometer (pressure gauge), the water flow passing through the heat pump must
decrease: Open the setting valve.
To decrease the pressure on the manometer (pressure gauge), the water flow passing through the heat pump must
increase: Close the setting valve.
For a normal working performance, inlet and outlet valves must be completely open.
Normal pressure
Pressure inside the refrigerant circuit of the heat pump and the water flow influence each other.
To work correctly, a water flow of 5 to 7 m³/h (100 l/min) should be maintained for maximum heat transfer.
If the value indicated on the pressure gauge is in the green area between 1,5 and 2,5, the water flow is CORRECT.
Set the water flow to 1,5 when water is cold (at the start of the season) and between 2 and 2,5 when water is about
28 to 30°C.
Warning: The Heat pump needs to operate for few minutes before the internal pressure stabilizes
Abnormal pressure
If the pressure is too high or too low, it indicates that the water flow circulating inside the heat pump is not correct.
You need to adjust the water flow by opening or closing the by-pass valve. Open little by little it if the pressure is too
low and close it little by little if the pressure is too high until it remains stable in the green area.
Pressure gauge must be between value 1 and 1,3 when the machine is stopped. If the value is 0, don't start the
machine (contact your seller).
