AIR TO WATER HEAT PUMP WATER HEATERAIR TO WATER HEAT PUMP WATER HEATER
2.18. Hot Water Connection
The hot water pipe be connection is to a G3/4 / 25mm socket as shown in the Installation
Diagram. NOTE: Plugs are supplied with the water heater to plug off the inlet / outlet ports
that are not required. Ensure that adequate sealing tape is applied to the plugs for a tight,
leak proof seal.
2.19. Tempering Valves
We recommend high quality, solar rated tempering valves fitted onto the hot water outlet
for supply of tempered water to 50 degrees C, as per regulations, to bathrooms, etc.
We recommend insulating the unused inlet / outlet ports.
2.20. Plumbing Components QIK Kit
The components of the QIK Kit have been designed to meet Australian plumbing regulations
including insulating gloves on components.
SIDDONS recommends the Siddons Solarstream QIK Kit (QIK15-SHP) or equivalent for
quality plumbing components for longer life of your Solarstream Water Heater and better
installation.
Water contains minerals which can cause problems especially when heated. Also, high
water pressure will reduce tank life so the QIK Kit contains a pressure limiting valve rated
to 2,000 kPa that will deliver water to the storage tank at an easy 500kPa. This will deliver
good water pressure but not excessive pressure that will waste water and shorten tank life.
The 3 way Tee is designed to supply both cold and hot water to the Tempering Valve.
The Pressure and Temperature relief valve, which is supplied with the unit, must be fitted
and made accessible so that the release mechanism can be operated and, if required
Warning:
A separate drain line must be run for the PTR valve. It is not permitted to couple the drain
lines from the PTR valve and evaporator into a single common line. It is acceptable to use
a tundish under the evaporator drain connected to the drain of the PTR valve.
through
malfunction / wear and tear, the PTR valve should be replaced. The outlet of the PTR valve
must be suitably drained to remove the water discharged during the normal heating cycle
in accordance with regulations.
The inlet Tee is designed to incorporate the Pressure Limiting Valve, the Non-return
Isolating Valve and the cold water Expansion Control Valve as well as supplying cold water
to the cold side of the Tempering Valve.
