Oil intake is arranged at frame top section, over its width, and composed of oil vessel with one top and oil discharge bore at bottom. Oil feed pipe arranged downstream of check filter is connected to heat pump cooling circuit. Outlet pipe of the latter is connected via the pump to bath inlet while heat pump heating circuit is connected with extra heater inlet and outlet. Case top part accommodates the guide of frame lower parts that stay in horizontal position.

EFFECT: higher efficiency.
