1.15 Basic Chemical Safety
When using chemicals, read the labels carefully and follow directions precisely. Though chemi-
cals protect you and your tub when used correctly, they can be hazardous in concentrated form.
Always observe the following guidelines:
• ALWAYS KEEP CHEMICALS OUT OF CHILDREN’S REACH.
• NEVER MIX CONCENTRATED CHEMICALS TOGETHER.
• ALWAYS THOROUGHLY RINSE ANY CONTAINER USED TO MIX CHEMICALS
AFTER USE.
• ALWAYS RINSE OUT ANY EMPTY CHEMICAL STORAGE CONTAINER
BEFORE DISPOSAL.
• Accurately measure the quantities specied. Do not overdose your tub. Amount required will
vary depending on water condition, quantities to be used are only guidelines.
• Store chemicals in a cool, dry, well-ventilated place.
• Always keep chemical containers closed when not in use.
• Do not inhale fumes or allow chemicals to come in contact with your eyes, nose or mouth.
• Wash your hands immediately after use.
• Follow the emergency advice on the product label in case of accidental contact.
• Never smoke around chemicals. Some fumes can be highly ammable.
• Do not store any chemicals in the equipment compartment.
ADDING CHEMICALS TO THE TUB
We recommend all chemicals be premixed in a bucket of water to ensure they dissolve. Then
pour the solution into the COLDTUB and run for 10 minutes before retesting.
IMPORTANT “SUPER CHLORINATION/OXIDIZER SHOCK TREATMENT”
NOTE: After adding chlorine or oxidizer to your tub, leave the cover open for a minimum of 20
minutes to allow the gasses to vent. Oxidizer gas may eventually cause discolouration or vinyl
degradation to the bottom of the cover and other components around the lip of the tub. This type
of damage is considered chemical abuse and not covered under warranty.
The COLDTUB Water Maintenance Program
Following the COLDTUB water maintenance program will save you time and frustration and
ensure clear, clean tub water.
As water evaporates from your tub and new water is added, the amount of dissolved minerals
will increase. The water may eventually become “hard” (Hardness too high) enough to dam-
age the heater by calcifying its surface.
