Please have a look at the diagramm shown on page 9.
1. Close cold and hot water supply page 9 (No. 4)
2. Attach hoses to both boiler drains and terminate the hoses in either a service basin or an appropriate spot outside the house.
3. Open both boiler drains at the same time to drain the Solpal system (No. 5),
WARNING: WATER MAY BE DISCHARGED AT VERY HIGH TEMPERATURES OF UP TO OR EXCEEDING 212 DEGREES
FAHRENHEIT. TO AVOID SCALDING, EXERCISE MAXIMUM CAUTION WHEN DRAINING THE HOT WATER FROM THE
SOLPAL. DO NOT POINT HOSE AT PERSONS OR PETS. ALWAYS DISCHARGE THE HOT WATER TO A SAFE PLACE.
4. After all water has been drained from the collector, close both boiler drains (No. 5) and remove hoses
The conventional water heater will continue to provide hot water to the household when the Solpal system is by-passed and drained.
Operating
If the homeowner cannot get water to flow from the hot water lines, the problem is probably with the local water source and not the sys-
tem. Check the cold water supply. To determine whether the Solpal system is working, observe the thermometer when hot water is being
used in the house. The water returning from the Solpal on a sunny day (No. 9b on page 12) should be at least 15 K warmer than the water
going up to the Solpal (No. 9a on page 12).
Increasing Efficiency
To increase the efficiency of the Solpal system:
– If possible, use hot water in the evening. For example take showers in the evening rather than during the day.
– The performance of Solpal system in the Northern Hemisphere is optimized when the Solpal is mounted facing true south.
Performance, however, suffers very little when the Solpal is oriented no more than 45° East or 45° West of True South.
– The collector should be in unobstructed direct sunlight between 9:00 a.m. and 3:00 p.m. on any day of the year.
System operating Pressure
The maximum operating pressure in the water circuit must be limited to 60 psi at all times. Install a pressure reducer if necessary.
Leaving the system unused
If the Solpal system is to be unused for a long period of time, such as absence due to vacation, it is best to leave the Solpal system filled
with water and in the solar pre-heat mode. If unused for long periods of time during winter months in freezing climates, it is best to drain
the collector and the solar loop piping. The entire system must be covered by a light-reflective cloth or foil to prevent damage due to over
heating. A original cover is available at your Solpal partner.
Don't touch the hot pipes!
