Filling The Brine System - York YHGS Installation Instructions Manual

When the brine lines are connected to the right for Geysir
!
Air, the brine out line must be routed over the brine pump,
under the compressor's vacuum pipe and under the
condenser's flexible hose, see figure below.
Figure 55: Routing of pipes for brine out for Geysir Air.
5. Install the supply line with all the accompanying components.
6
. Install the expansion tank with the safety valve.
7.
Fit both brine lines with anti-diffusion insulation running all the
way from the heat pump to the lead-in in the wall. The brine
lines running outside the house to the collector can be buried,
however they must be well insulated.
Applies to Geysir Air: Bear in mind that the outdoor unit may
!
move during defrosts, use flexible hoses to connect the pipes
from the heat pump and pipes on the outdoor unit.

8.7. FILLING THE BRINE SYSTEM

NOTE! Before filling the brine system, the electrical installation
!
must be completed so that it is possible to operate the brine
pump.
NOTE! Before filling the brine system for Geysir Air, the water
!
MUST
heater be filled before the anti-freeze tank is filled.
NOTE! Always check local rules and regulations before using
!
anti-freeze.
NOTE! Use anti-freeze with corrosion protection additives,
!
mixed to achieve frost protection down to -15°C.
NOTE! Use only ethylene glycol anti-freeze for Geysir Air,
!
mixed to achieve frost protection down to -32°C.
Calculated volume, Geysir, Geysir with Passive cooling
n
The volume of the brine system is calculated as follows:
Heat pump (exchanger and piping) approximately 2 litres
l
Expansion tank approximately 3 litres
l
Collector (single pipe): PEM 40 approximately 1.0 litre/m; PEM
l
32 approximately 0.6 litre/m; Cu 28 approximately 0.5 litre/m
Calculated volume, Geysir Air
n
The volume of the brine system is calculated as follows:
Heat pump (exchanger, pipe and outer jacket) approximately 47 litres
l
Expansion tank approximately 3 litres
l
Outdoor unit approximately 7 litres
l
Collector (single pipe): 28 mm pipe approx. 0.5 litre/m

Filling kit
n
When the filling kit is installed on the return line, remember to turn
the strainer cover upwards in order to minimise the amount of air
that gets into the brine system when cleaning the filter.
