9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise safety, then no

fault cannot be corrected immediately, but it is necessary to continue operation, an adequate
temporary solution shall be used on the advice of an electrician or our customer service team.
This shall be reported to the owner of the equipment, so all parties are advised.
Initial safety checks shall include:
• Ensuring that capacitors are discharged: this shall be done in a safe manner to avoid possible

7. Repairs to Sealed Components
1) During repairs to sealed components, all electrical supplies shall be disconnected from the unit
being worked on prior to the removal of sealed covers and other parts (if any). If it is necessary
to have an electrical supply connected to the unit during servicing, then a permanently operating
form of leak detection shall be located at the most critical point to warn of a potentially
hazardous situation.
2) Particular attention shall be paid to the following to ensure that when working on electrical
components, the casing is not altered in such a way that the level of protection is affected. This
shall include damage to the cables, an excessive number of connections, terminals not made to

to carrying out this task, an oil and refrigerant sample shall be taken in case analysis is required before
reusing the reclaimed refrigerant. It is essential that electrical power is available before this task
commences.
a) Become familiar with the equipment and its operation.

The recovery process is always supervised by a competent person and recovery equipment and
cylinders conform to the required standards.
d) Pump down the refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerants can be removed from various
parts of the system.
f) Make sure that the cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with the manufacturer's instructions.

16. Recovery
When removing the refrigerant from a system, either for servicing or decommissioning, it is
recommended that all refrigerants be removed safely.
When transferring the refrigerant into the cylinders, ensure that only appropriate refrigerant recovery
cylinders are used. Ensure that the correct number of cylinders for holding the total system charge
is available. All cylinders to be used are designated for the recovered refrigerant and labeled for that
refrigerant (i.e., special cylinders refrigerant recovery). Cylinders shall have pressure relief valves and
associated shut-off valves in good working order. Empty recovery cylinders should be evacuated and, if
possible, cooled before the recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the

complete with leak-free disconnect couplings and be in good condition. Before using the recovery
machine, check that it is in satisfactory working order, has been properly maintained, and that any
associated electrical components are sealed to prevent ignition if a refrigerant is released. Consult
Customer Service when in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder,
and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially
not in cylinders. If the compressors or the compressor oils are to be removed, ensure that they have

FCC STATEMENT
The remote control of this air conditioner complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) the remote control may not cause harmful interference, and (2) the
remote control must accept any interference received, including interference that may cause undesired
operation.
The remote control has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. The remote control generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If the remote control does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the distance between the remote control and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
– Consult the dealer or an experienced radio/TV technician for help.

A replacement product may be provided instead of repairing a defective product. hOme™’s exclusive
obligation under this warranty is limited to such repair or replacement.
A receipt indicating the purchase date is required for any claim, so please keep all receipts in a safe
place. We recommend that you register your product on our website: homelabs.com/reg. Although greatly
appreciated, the product registration is not required to activate any warranty and product registration
does not eliminate the need for the original proof of purchase. The warranty becomes void if attempts
at repair are made by non-authorized third parties and/or if spare parts, other than those provided by
hOme™, are used. You may also arrange for service after the warranty expires at an additional cost.
These are our general terms for warranty service, but we always urge our customers to reach out to us
with any issue, regardless of warranty terms. If you have an issue with a hOme™ product, please contact
us at 1 [phone], and we will do our best to resolve it for you.
