Heat Pump Installation - AZURO BP-50HS-A Installations- Und Bedienungsanleitung

(d) The air outlet should not be directed to areas, where the increased circulation of cold air may be bothering (windows, terrace, etc.). The air outlet should
not face against the direction of prevailing winds.
(e) The equipment distance from the pool edge shall not be shorter than 3.5 m. It is recommended to install the heat pump at the distance of 7 m from the
pool provided that the overall length of interconnecting pipe system will not exceed 30 m. One should take into account that the longer the pipe, the
greater the heat loss. To get an idea, a 30m long pipe system will show the loss of about 0,6 kW per hour (2000 BTU) for each 5 °C diff erence between
the temperatures of pool water and the ground (provided that the pipe system is buried in dry ground). Such loss represents the increase of 3-5 % in the
time of heat pump operation.
(f) The equipment shall be placed on a fi rm and even surface, such as a concrete slab or steel base and the heat pump housing shall be padded with vibration
isolation mounts (rubber silent-blocks) and attached by bolts or screws to the base in order to reduce noise and extend the heat pump service life
(g) The rear side of the evaporator consists of lamellae made of soft metal and is liable to mechanical damage. Therefore, adequate measures should be taken
and suitable site chosen to have the lamellae protected from damage.
Note: If it is intended to use the heat pump for an indoor pool the supplier should be consulted concerning pump placement and its connection to the pool.

HEAT PUMP INSTALLATION

(a) The heat pump should be used in combination with the fi ltration unit comprising a part of user's installation of the pool. The fl ow through the heat pump
should correspond to its recommended value (see Table 3.1 Technical Data) and shall not be more than two times higher. In order to provide for the
proper operation of heat pump the bypass line shall be installed. The system consists of three valves that allow setting the fl ow rate through the pump
(see chapter 6.2 Operational State Setting Using Bypass).
(b) The heat pump is fi tted with inlet and outlet fi ttings with cap nuts and sealing rubber rings for connecting the pump to D50 pipes. For connection to the
fi ltration circuit use a D50 PVC tube, or 50/38 reducing fi ttings that allow using the ø 38 mm hose. The lower and upper fi tting should be used for heat
exchanger inlet and outlet, respectively. Before screwing the caps nut on, apply lubricant on the threads.
Insert the D50 tube into the sleeve piece of heat exchanger no less than 1 cm and no more than 2 cm.
Consider also the use of quick couplers for the heat pump inlet and outlet to make easier its connection to and disconnection from the fi ltration circuit for
draining all water before wintering or commencing maintenance/service works.
(c) The heat pump shall be connected to the pool fi ltration circuit downstream of the fi lter and upstream of the water treatment equipment (automatic
chlorine dispenser, ozoniser and so on). A typical connection of fi ltration circuit is shown on the following fi gure.
Note: In case the automatic chlorine dispenser is used in the fi ltration circuit, a check valve with titanium spring shall be installed upstream of the dispenser. Failing this, in the
course of pump standby time chlorine concentration will increase in the exchanger of heat pump above its permissible level and cause damage to the exchanger.
