Section I General Information; Introduction; Warranty; Maintaining Proper Water Chemistry - Trane TR250 Service & Installation Manual

SECTION I. GENERAL INFORMATION

INTRODUCTION:

This manual contains instructions for installation, operation, maintenance, troubleshooting, and parts lists
for the safe use of the swimming pool/spa/hot tub heaters. The manufacturer strongly recommends that the
installer read the manual before installing the swimming pool/spa/hot tub heater. If after reviewing the manu-
al any questions remain unanswered, contact the factory or local representative. Following heater installation,
the installer should leave all manuals with the consumer for future reference.
LIMITED WARRANTY SUMMARY:
The manufacturer warrants the pool/spa/hot tub heater to be free from defects in materials and workman-
ship, and will within one year from date of installation for all users, for the original purchaser, repair or, at our
option, replace without charge any defective part. The manufacturer further warrants that if the heat exchang-
er or exchanger headers (water-containing section) leak within one year from date of such installation for all
users, due to defects in materials and workmanship, replacement parts will be provided by the manufacturer.
Cost of freight, installation, fuel, and service labor (after one year) is at user's expense. For full details of
warranty agreement, see warranty certifi cate included in this manual.
If the pool/spa/hot tub heater is damaged or destroyed by improper maintenance, exces-
ATTENTION:
sive water hardness, incorrect water chemistry, or freezing it is not covered under the manufacturer's

warranty.

MAINTAINING PROPER WATER CHEMISTRY:

WARNING: Failure to maintain proper water chemistry may cause premature
heat exchanger damage or failure.
The heat exchanger in your Trane pool heater is made from the highest quality of copper and nickel (Cu-
pronickel) materials. The premium materials and the exacting processes used in the manufacture of the heat
exchanger is state of the art in pool heater design and manufacture. Yet, it remains vital that the heat exchang-
er be protected from damaging or corrosive chemicals, insuffi cient water fl ow or improperly balanced water
chemistry. Heat exchanger damage or failure resulting from improper fl ow, improperly balanced pool water
or the improper addition of sanitizers into the water is NOT covered under the terms of your warranty.
The following factors are critical to heat exchanger protection. Follow these guidelines to help prevent
pre-mature damage or failure to your heater and heat exchanger.
1. WATER FLOW THROUGH HEATER
Water must be fl owing through the heater at the minimum rated fl ow rate during operation. Check that
the pump is operating and the system is fi lled with water and purged of all air prior to starting the heater. The
minimum rated fl ow rates are listed on page 25. Some installations may require an adjustment to the water
pressure switch for proper low-fl ow protection. Test your system and if necessary, adjust the water pressure-
switch as described on page 35.
2. POOL/SPA WATER CHEMISTRY
The chemistry balance and mineral content of swimming pool water changes daily due to the addition of
pool and sanitizing chemicals, bather loads, rain, runoff and the amount of sun - to name a few. Improper chem-
istry balance and mineral content can cause scaling and deposits to form on pool walls, in the fi ltration system,
in the heat exchanger tubes and additionally can promote corrosive action to all metals in the water path. Chang-
