Heat pump PVP Inverter
MA20-14E rev 1
ENGLISH
It is important that this manual is read carefully by both the installers and users to ensure the heat pump’s function and lifetime.
Pahlén AB is not responsible for any damage due to improper installation, mishandling or improper maintenance.
Product description
Pahlén heat pump Aqua PVP is intended for heating the swimming pools or whirlpools. It is intended for operation at air
temperatures between -7°C and + 43°C to obtain 18-35°C of the pool temperature (maximum power is achieved at the air
temperatures between +15°C and +25°C).
Heat pump efciency is inuenced among other things by water, air and pool temperatures. On cold days and nights,
the operating time required to obtain the desired temperature in the pool becomes longer than on hot days . For economy
reasons it is better to cover the pool when not in use, especially at nights. Approximately 60-70% of the heat is lost through the
pool water surface. Covering the pool therefore reduces the heat pump operating time.
By-pass-kit (item no. 14950181 for c-c 340 mm and 390 mm, 14950182 for c-c 620 mm) is a Pahlen accessory containing all
connections required for proper installation, and allows to easily adjust the optimal water ow through the heat pump.
Key functions
This heat pump is equipped with safety functions that automatically stop the operation in order to protect the heat pump.
The display shows the current pool temperature, or an error code if an error occurs.
Flow switch
The ow switch is turned on when a sufcient ow of pool water ows through the heat pump’s titanium heat exchanger .
At low ow or no ow, the heat pump shuts off, and the display shows “E3” error code.
When the ow returns to normal, the heat pump restarts automatically.
High and low pressure guard
Protects compressors. The pressure switch can detect the refrigerant circuit pressure at high pressure/ low pressure sides and
turn off the heat pump at too high/low pressures.
If the pressure switch detects a too high pressure, the display shows “E1” error code. If the pressure switch detects a too low
pressure, the display shows “E2” error code. When the pressure returns to normal, the heat pump restarts automatically.
Low outdoor temperatures
The heat pump automatically shuts off if the outside temperature is too low for the pump to produce heat.
The display shows “Eb” error code. Heat pump restarts automatically when the outdoor temperature becomes too high.
The exact temperature for disconnection varies depending on the current weather (and the amount of sunlight), and activates
the temperature sensor positioned on the heat pump back side.
Restart delay
Heat pump has a 3-minute restart delay (to prevent the compressor thermal overloading caused by the refrigerant pressure
being not balanced, which can occur at short starts and stops).
Operating mode
Heat pump has two different operating settings: “Smart” and “ Silence”. They have different advantages in different situations.
Smart:
The operation is automatically adapted to the air and water temperatures in order to quickly heat the pool to the desired
temperature. Recommended during the heating phase:
Silence:
Heating capacity between 25 and 80%, noise level 3% lower than in the “Smart” operating mode.
Recommended at night or when the pool has the required temperature, and the ambient temperature is at least 15°C .

Installation
Water ow through the heat pump is driven by the external pool circulation pump. The recommended water ow is shown in the
technical specication.
Placing
Placing of the heat pump is very important and can affect its performance and maintenance options.
Consider the following factors:
• Heat pump must be installed outdoors in a well-ventilated place in order to avoid cold air recirculation.
It requires at least 300 mm clearance from the walls, shrubbery or the like around the heat pump in order not to block air intake.
Note also that the pump requires at least 2500 mm space in front of it in order to prevent air recirculation.
We do NOT recommend placing the pump under the eaves, wooden decks or porches, since this may cause cool air
recirculation that can greatly affect performance.
• Consider that it should be easy to access around the heat pump at installation (plumbing and electric works), and that enough
space is also available for future maintenance .
• The total length of pipe between the heat pump and the pool should not exceed 10 meters. Heat pump must ALWAYS be
connected with a xed tube.
• It should be placed on a rm, level surface, on a 300-400 mm high concrete base or a tripod that can handle its weight.
Fix the heat pump frame/feet with M10 bolts.
• Heat pump should never be placed near any source of explosive or corrosive substances.
• In order to protect the heat pump in exposed locations, prevent sand or air with high salt content (since this can cause clogs,
damage or corrosion to the pump), you can plant shrubs or put up fences for protection, but at a good distance from the
heat pump.
• When the heat pump is working, condensation water is formed in the bottom. Make sure that the supplied drainage hose for
water drainage has been installed.

Pipe installation
Heat pump must always be connected with a xed PVC pipe Ø50 or a bypass kit (recommended by Pahlén ).
The pipes may need to be relieved, so that the connections do not have too much burden (breakout force can damage the
heat exchanger).
Any tightening of the coupled connections to the heat pump should be made by hand (tools can damage connections).
To protect the heat pump from dirt and snow it is optimal to place it on a base or stand above the ground level.
NOTE! The pipe length between the pump and the pool should not be more than 10 meters.
Install the supplied drain connection down through the holes in the heat pump’s base. Connect it to the following drainage hose
and make sure that wastewater and condensate are drained from the heat pump.
Electric installation
Electric installations must be performed by a qualied electrician in accordance with applicable regulations.
Installation must be preceded by installation of a residual current device and maintenance switch.
Never start the pump until all wiring and re-checking are performed.
