REMKO WKF 85 - Manual (Page 45)

Ensured discharge in the event of leakage
With the REMKO oil separator OA 2.2, the below
listed requirements of local regulations and laws
are met.
NOTICE!
Local regulations or environmental laws, for
example the German Water Resource Law
(WHG), can require suitable precautions to
protect against uncontrolled draining in case of
leakage to provide for safe disposal of
escaping refrigerator oil or hazardous media.
NOTICE!
With the connection of an external drain line to
the oil separator, it must be kept frost-free.
5 Hydraulic connection
A separate interpretation of nominal flow rate
must be made for every system (see technical
data).
n For hydraulically isolation of the heating cir-
cuits, a buffer storage can be installing as a
hydraulic switch.
n Make a pipe-network calculation before instal-
ling the heat pump. After installing the heat
pump, it is necessary to perform a hydraulic
balancing of the heating circuit.
n Protect floor heating systems against exces-
sively high inlet temperatures.
n Do not reduce pipe diameters for the supply
and return connections to the heat pump
before connecting a buffer tank-unit.
n Plan for air bleed valves and drain-off taps at
appropriate places.
n Flush the the system's entire pipe network
before connecting the heat pump.
n One or, where necessary, several expansion
tanks must be designed for the entire hydraulic
system.
n The system pressure of the entire pipe network
is to be matched to the hydraulic system and
must be checked when the heat pump is
turned off. Also update the static-pressure form
supplied with the heat pump.
n As delivered, the safety assembly consists of a
manometer, air bleeder and safety valve. It is
to be mounted to the pipe connection provided
on the indoor unit.
