Ensure duct work pressure drop does not exceed resistance given in data sheet.
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 - damper plate fitted on side of fan CAN be removed if ducting is fitted
(all versions) but fan amps MUST be verified to be as per data sheet fan amps with
dry coils, clean air filter and all panels fitted.
