If unit is located in a plant room at pool hall air temperatures, any ambient air ducting must be heavily insulated.
Recommend fresh air/exhaust spring return dampers to be fitted to ductwork for sub zero ambient
applications in case of power failure.
IMPORTANT - 600 and 900 models are fitted with constant flow fans and deliver the optimum
airflow, self compensating for pressure differentials in the system.
On 1200 and 1500 models ensure duct work pressure drop does not exceed resistance given in
data
sheet
.
Damper plates fitted on side of fan CAN be removed if ducting is fitted but fan amps
MUST be verified to be as per data sheet fan amps with dry coils, clean air filter and all
panels fitted.

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
AW600, 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. AW1500 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.
