Commissioning Of The Crossflow System; Setting The Delivery Temperature - Rheem Crossflow RD200 Owner's Manual And Installation Instructions

COMMISSIONING OF THE CROSSFLOW SYSTEM

Potable and Non-Potable Water Circuit
All lines must be flushed of debris prior to filling the system. Failure to observe this requirement may lead to
system blockage and/or underperformance. Check and clean the line strainers after flushing.
Fill the potable water circuit by opening the isolation valve at the cold water inlet connection on the potable
water side of the Crossflow. Open a hot tap so air may be purged from within the system whilst filling. Close
hot tap when all air has been expelled.
Fill the non-potable water circuit by opening the isolation valve at the "Heating Source In" and "Heating
Source Out" connections on the non-potable water side of the Crossflow. Ensure air is purged from within
the system whilst filling.
When full operational pressure is reached, ensure that all connections on both circuits are free of leaks. The
non-potable water circuit MUST BE full and pressurised before any other tests are conducted to avoid
potentially damaging the Crossflow pump. Failure to observe this precaution will result in warranty being
void.
Switch on the electrical power to the Crossflow and follow the instructions below to set the temperature.
