  • Page 25: Multiple Installations

    MULTIPLE INSTALLATIONS A multiple installation of Solahart 27 litre in-series gas boosters on a single manifold is possible, using a parallel plumbing arrangement, where large volumes of hot water are required. It is good practice, but not ® essential, to install the water heaters in an Equa-Flow plumbing arrangement.
  • Page 26 MULTIPLE INSTALLATIONS PRESSURE REDUCING VALVE COMMISSIONING PROCEDURE The pressure reducing valves must be set and commissioned for each water heater so the water heaters will turn on and off in sequence when the flow rate increases or decreases to a particular rate. This procedure can be conducted with either cold water or solar heated water, however the temperature of the solar heated water must not exceed 58°C.
  • Page 27 MULTIPLE INSTALLATIONS To set and commission the pressure reducing valves: Commissioning: Commission each of the water heaters prior to setting the pressure reducing valve on “Commissioning” the solar preheat branch to the water heater (refer to on page 28). Turn on services: Turn on the water, gas and electricity to the water heaters. Locking screw: Loosen the locking screw on each SYR valve with a flat bladed screw driver.

    COMMISSIONING All water heaters are tested and adjusted before dispatch from the factory, however further adjustments may become necessary because of local conditions. Note: If this water heater is installed as part of a multiple installation, i.e. in a bank of water heaters, it will be necessary to isolate the other water heaters and commission the water heaters one at a time.
