7. MAINTENANCE & SERVICE INFORMATION
Your Solarstream water heater is a completely sealed refrigeration system, similar to a household
refrigerator except that it operates in the opposite direction, heating rather than cooling. The
maintenance program to be used on your Solarstream is not much different to that required for
the maintenance of a refrigerator and a standard electric water heater. NOTE: Before any
electrical components are inspected, your Solarstream MUST be turned off at the power switch.
7.1 Heating time
Your Solarstream should heat all of your tank water in approximately 4 hours depending on the
air temperature and humidity. The reheat time will be less with warmth already in the storage
tank. Get to know the heating characteristics of your Solarstream in your location with your
normal hot water demand. Monitor for any significant change to this, keeping in mind that
Summer time warmer temperatures will enable quicker heat up time.
7.2 Air Evaporator Coils
Solarstream water heaters use evaporator coils to extract heat from the air. The coil is extremely
efficient in warm, humid weather. However, as temperatures drop below 5 degrees C, the coil will
begin to collect ice. The coil has been designed with an auto-defrost mode for such conditions.
The defrost system is automatic and is managed by the digital controller. It is important that the
air inlet vents are kept clean. Restriction of air flow to air-inlet or outlet vents may void your
warranty if the system has been damaged because of insufficient airflow (refer Section 13).
These devices must not be tampered with or removed. The water heater must not be operated
unless each of these devices is fitted and in working order.
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for their
safety. Children should be supervised to ensure that they do not play with the appliance.
WARNING: For safe performance, this water heater is fitted with:
1) Digital Controller
2) Thermostat (connected to the digital controller) to manage water temperature
3) Thermostat (connected to the digital controller) to manage compressor temperature
4) Non self-setting thermal cut out switch (incorporated into the digital controller)
5) Pressure & Temperature Relief valve

AIR TO WATER ALL IN ONE HEAT PUMP
7.3 PTR valve maintenance
Your Pressure & Temperature Relief (PTR) valve is functioning normally if there is some
discharge at the end of each heating cycle. The PTR valve should be checked for adequate
performance or replaced at intervals not exceeding 5 years, or less in areas where there is
mineralised water causing a high incidence of mineral deposits from the hot water. Lifting the
lever on the PTR valve should be done with care at least once per year. If the PTR valve
continues to drip after releasing the lever, there is a possibility that some sediment or grit may
have settled on the valve seat. Try lifting the lever again and carefully releasing it. If the drip
persists, contact your plumber (refer to Section 4.4).
7.4 Adding an Expansion Control Valve (ECV)
In areas with mineralised water causing a high incidence of mineral deposits from the hot water,
an Expansion Control Valve (ECV) should be installed allowing cold water to be released rather
than hot water during the heating cycle. We recommend this to be installed. If in doubt, check
with your plumber; refer to Section 4.5.
