inclined ABS pan extension may be supplied with the unit as an option. This
recovers condensate from the valves and drains it via gravity or using a
condensate drain pump (supplied as an option).
- Installation
To avoid damaging the CIAT valves or couplings, never torque tighten to more
than 3.5 daN.m. Use two wrenches, one to hold and the other to tighten, to ensure a
tight seal.
Always fit the valve in the right direction. On these 2 CIAT couplings, the direction of
flow should be
The maximum allowable differential pressure for our valves (open or closed) is
100 kPa. We recommend not exceeding 60 kPa.
The positioning of the hydraulic networks is crucial to the correct operation of the
system. Drain valves should therefore be placed at the appropriate points and in
sufficient number. In addition, strainers should be fitted, as well as drains at circuit
high points, balancing tees and shut-off valves on each coil and, if necessary,
discharge valves.
- Filtration:
An efficient filtration system (recommended efficiency of 0.5 mm) should be fitted on
the supply water and return water lines.
The system must be flushed completely and filled with treated water to prevent the
build-up of scale or sludge in the circuit. When flushing the system,
on the unit to prevent any sludge or impurities from building up in the coil:
There are two options:
1) Remove the servomotor and fit the cap, which will cause pressure to be applied to
the shaft, thereby opening the valve.
2) Request that the control valve opens via the controller.
There are two options:
1) If the power has not yet been switched on, the valve will be open by default.
2) If the control has already been powered up, remove the servomotor to release the
rod and open the valve.
