3.13 COLDTUB Pal Version 1 R1
Maintenance Schedule
Item Frequency Maintenance Task Target Range
The following table outlines the typical water maintenance program required for an COLDTUB
tted with COLDTUB Pal Version 1 R1.
To help ensure chemicals dissolve appropriately it is good practice to rst mix/dissolve the
chemical in an uncontaminated container of hot water before carefully adding to the Tub water.
There are two methods to check the target range:
• COLDTUB Pal Application, if your Tub has Wi-Fi and access to the internet through
your home network or portable device such as iPad or smart phone, you can log onto
COLDTUB Pal and open the Settings or Diagnostics Page to review the readings (To
access COLDTUB Pal you must rst register your details on the COLDTUB Pal web site:
www.mycoldtub.com.
pH Weekly Check the Potential Hydrogen (pH) to
ensure it is in the target range.
Always rst check to ensure the pH is
within the target range. If the pH is out
of the target range pH must be adjusted
before making any adjustments to chlo-
rine levels
7.2 – 7.6 pH As Salt systems naturally drive pH levels upwards, it is most critical to the performance/
life of the salt system to maintain the pH within the target range.
High pH reduces the effectiveness of chlorine.
Therefore, high pH causes your COLDTUB Pal system to produce more chlorine thus
increasing pH even higher and reducing the effectiveness of chlorine even further.
Strive to achieve a Low pH level 7.0. pH must not exceed 7.6.
Low pH - Can be raised by adding COLDTUB Cold WaterJump to the Tub water.
High pH - Can be lowered by adding COLDTUB Cold Water Run Down to Tub water.
ORP Weekly
(& before
each use)
Check the Free Chlorine Level to ensure
it is in the
target range.
545–550 mV 545-550 mV is the Optimum Range factory default setting.
The user may adjust higher if preferred through the COLDTUB Pal Web Page.
COLDTUB Pal will strive to maintain ORP within the Optimum Range.
Depending on the water chemistry which will be affected by bather load and Tub usage,
at times the ORP value will overshoot or undershoot the Optimum Range.
Sodium
Chloride
Monthly Check the Sodium Chloride Level to
ensure it is in the target range.
Version 1 R1
1500 – 1800
ppm
Once Sodium Chloride reading is in the target range salt concentration will only change
if water is splashed or drained out. Do not add salt unless this test conrms the level is
below the chemical acceptable range.
High Sodium Chloride - add water.
Low Sodium Chloride - add salt.
Filter 3 Monthly Change the lter(s) N/A Change the lter(s) in accordance with Owners Manual instructions.
Water 6 Monthly Change the water N/A Change the water in accordance with Owners Manual instructions.
