• Controller records ko maintenance logs
• Previous invoice ko packing label
• Hotunan compressor da ya lalace daga kusurwoyi da yawa

Ga distributors, neman hoto mai kyau na nameplate da terminal box sau da yawa shi ne hanya mafi sauri don guje wa kuskuren oda.

2. Nau’in refrigerant

Kwampresan maye gurbi dole ya dace da refrigerant da ake amfani da shi a cikin tsarin. Refrigerants na yau da kullum suna bambanta bisa aikace-aikace da kasuwa, kuma dokokin refrigerant ma suna bambanta daga ƙasa zuwa ƙasa. Kwampresan da aka ƙera don wani refrigerant guda ɗaya ba za a iya amfani da shi kai tsaye da wani ba.

Duba ko tsarin yana amfani da refrigerants kamar R134a, R404A, R507, R22, R407C, R410A, R290, R600a, R32, CO2, ko wani refrigerant da aka ayyana. Haka kuma tabbatar ko an yi wa tsarin retrofitting daga tsohon refrigerant. Tsarin da aka yi wa retrofitting yana buƙatar ƙarin kulawa saboda nau’in mai, zaɓin bawul ɗin faɗaɗawa, da kewayon matsin lamba na iya daina dacewa da ainihin lakabin kwampresan.

Ga hydrocarbon refrigerants kamar R290 da R600a, dole ne a zaɓi maye gurbi tare da bin ƙa’idodin aminci da dacewa da aikace-aikace. Kada a maye gurbin da kwampresan da ba a amince da shi ba cikin tsarin refrigerant mai saurin ƙonewa.

3. Ƙarfin sanyaya da yanayin ƙididdiga

Ƙarfi yana ɗaya daga cikin mafi yawan tushen kurakuran cross-reference. Kwampresan da ake tallatawa da wani horsepower ba ya wadatar. Horsepower kwatancin kasuwa ne na kusan, ba daidaitaccen ma’aunin zaɓi ba.
