VII. Maintenance

In general, very little maintenance or repair is required on Water-to-Air Heat
Exchangers.

Blowers - Removable for Repair or Replacement

In Water-to-Air Heat Exchangers, powerful blowers are used.  Each is carefully chosen
to provide optimum airflow characteristics for component cooling as well as heat
transfer within the unit.

Each of these air moving devices has been engineered and constructed to provide
years of trouble-free operation and thus require no periodic maintenance.

In the case of air mover failure, blowers are easily removable with simple tools.

Replacement Blower Assemblies and Motors are generally readily available from
Kooltronic stock.

Please see the listing of Major Component Replacements earlier in this Manual.

VIII. Packing Procedure

Keep Heat Exchanger in proper upright position.

Pack Heat Exchanger in an appropriate carton (preferably original carton if possible),
with adequate internal protective packaging, making sure carton is marked properly.

For local controlled transportation, strap carton where possible, to a secure part of
truck to prevent falling or sliding, minimizing vibration, etc.

For common carrier shipment, band unit(s) securely to a pallet. Unpalletized shipment
risks severe damage which voids the warranty.

CAUTION

Disconnect electric power from the Heat Exchanger before

servicing unit.

CAUTION

Do not handle or carry the blower by inserting fingers into the

blower opening where wheels are located.  This could cause a

wheel misalignment problem and create an out-of-balance

condition.  Also, the sharp vanes could result in injury.
