
Pool Water Chemistry . Incorrect pool water chemistry (improper pH level or high concentration of chlorine,
sea salt or other corrosive additives etc.) can result in equipment premature wear or malfunction (let alone
poor air quality in the pool and potential health issues) and will void the equipment warranty. Refer to pool
water quality standards; contact factory as needed.
Routine Maintenance Program
Creating facility-specific routine maintenance program and following it is vital to equipment longevity and efficient
operation.
The suggested general maintenance operations and their frequency/intervals, listed in the table M-1 below, can be
used to create such a program. For more detailed maintenance recommendations related to specific components,
refer to the respective component manufacturer’s manual.
Table M.1. Recommended Maintenance Tasks and Intervals
Interval Maintenance Task
Weekly Observe the equipment for any changes in running conditions and unusual noise
Quarterly
Clean or replace air filters if clogged or dirty
Verify that all set-points are correctly programmed as specified by the facility operator
Semi-
Annually
Inspect and clean the drain pan(s)
Tighten electrical connections, if required
Check and tighten, if required, pool water hose clamps and sensor mounts
Inspect all airside coils (outdoor condenser, fluid cooler, dehumidifier coils – evaporator, etc.) for
dirt, cobweb build-up, etc.; clean as needed
Check that the P-trap is primed (filled with water). It is good practice to pour some water into the
drain pan to ensure that the P-trap is primed and operational
Check the outdoor air louvres and dampers for accumulation of dust and clean as required
Inspect the equipment’s cabinet for corrosion. If any damage is found, clean and repaint the
affected surface with a rust-resistant primer
Annually
Clean the fan wheel(s)
Check dampers operation (linkage/actuator is not loose, damper opens/closes properly etc.)
Inspect electrical components, wiring and insulation
Rotate the fan wheel(s) and check for obstructions and rubbing
Check gasket condition on all doors to ensure an airtight seal
Check bolts on compressors, motor mounts, dehumidifier bases and coils and tighten if required
Verify that the airflow around the remote condenser or dry cooler is unobstructed
