Repair to electrical components by non-certified technicians may result in
personal injury and/or damage to the unit. All electrical components replaced
must be genuine MovinCool parts, purchased from an authorized reseller.
2. The power supply for this unit should be a dedicated single outlet circuit with
UL recognized short-circuit and ground-fault protective breaker.
3. Because of potential safety hazards under a certain condition, we strongly
recommend against the use of an extension cord.
However, if you still elect to use an extension cord, it is absolutely necessary
that it is a UL listed, 3-wire grounding type appliance extension cord, having a
3-blade and a 3-slot receptacle that plugs into the appliance.
The marked rating of the extension cord should be 115 V, 15 A or equivalent.
4. This unit is equipped with a 10 feet (3 m) UL recognized LCDI power cord. For
replacement, fixed location (hard wired) or power cord lengthening (extension
cord) cords are required, contact your reseller or a qualified electrician for
approved replacement methods.
5. Never fold or place heavy objects on the power cord.
This could result in damage to the power cord causing electrical shock or fire.
6. Turn the unit off and disconnect the power when the power cord is damaged.
7. Do not place water or any other liquid on the unit. This can cause damage to
the unit and increase the risk of electrical shock.
8. Do not sit or stand on the unit.
9. Do not operate the unit without water connection or without supplied water.
10. If the entering water temperature is below 68 °F (20 °C) or above 86 °F (30
°C), adjustment of the unit's water regulating valve setting is required
(see page 29). Failure to adjust this valve may damage the unit and void the

ILL00205-00
Default Valve Setting and Operation Range
Default setting of the valve opening temperature is 86 °F (30 °C) and marked on
the valve housing. If the entering water temperature is below 86 °F (30 °C), there
is no loss of water while the unit is not operating. Adjustment of the valve setting
is required only when the unit will be used under the following conditions.
Entering water temperature is below 68 °F (20 °C):
Valve setting must be adjusted to lower temperature to extend the life of the
compressor.
Entering water temperature is above 86 °F (30 °C):
Valve setting must be adjusted to higher temperature to prevent wasted water.
Note: This adjustment expands the minimum water temperature range. Carefully
control the operating range.
CAUTION: Failure to adjust the water regulating valve or operating
the unit with entering water temperature below 68 °F (20 °C) without
adjusting the valve setting may damage the unit and void the
warranty. Contact a qualified technician for details.
