Damage to blue polyethylene housing.
Leaking from bottom of pads.
Excessive water pressure.
Float valve maybe stuck in open position.
New pad may have a temporary odor (this
is normal) – you may be smelling the
thermosetting resin on the new pads
– it will pass.
Water quality – check your immediate
environment.
Check your water flow valve first.
Water supply off at main valve source.
Pump switch is off.
Water filter may be clogged.
Hard water with excessive mineral content.
Solution (continued)
Repair as necessary.
Reduce the water flow with the water control
valve located on the front of the unit.
Search for leaks and repair as necessary.
Push bottom of cooling pads gently inside to
stop leaking.
Check you pressure. Max water pressure is 413
KPA (60 p.s.i.), adjust water supply valve to
1 ¼ turns or install a water pressure regulator
found at local hardware store.
Contaminants in water; drain cooler, sump and
refill. If float remains stuck remove pads and
examine float for debris or damage. Wash out
debris and replace float. Continue.
Drain and refill several times in first week to
remove thermosetting resin smell.
Add QC Tablets to reduce smell – and algae.
Water should be drained about once a month or
sooner depending on your specific working
environment – the water quality and conditions.
Make sure your water flow valve is open.
MaxxAir units usually operate at peak
performance at 1 ¼ turns.
Open water valve at supply. You may wish to
keep this valve open at all times.
Turn pump switch on.
Remove the cooling pads see section 6.2. Open
back of unit – open water filter – pull out filter
screen and clean. Replace and try again.
Use Evapo-O-Matic Tablets or add a Water
Stabilizer at the discharge side of the pump.
Flush water from unit’s water reservoir more
frequently. See section 7.4.
