All ambient air ducting should be suitably insulated if plant room temperatures are significantly different from ambient, particularly where the plant room is at pool
conditions. Spring return dampers are recommend for exhaust and fresh air ductwork in installations with sub zero ambient temperatures, in case of power failure.
Important
AA600, 900 and 1200 models are fitted with constant flow fans and self-regulate to deliver the optimum airflow, compensating for pressure differentials in the
system. AA1500 models are fitted with a variable speed, so the fan speed should be commissioned to ensure the correct volume (with dry coils, clean air filter and
all panels fitted). See data sheet for pressures available.
